Maldives Floating City is planned to accommodate up to 20,000 residents. Badly needed. Global warming is sinking the country.

Is it possible to reverse the harm we’ve done to the planet after burning so much fossil fuel? For the people of Maldives, time is of the essence, and they’re not waiting to find out.

Alice Finney writes at dezeen, “The Maldives has partnered with architecture studio Waterstudio to create a brain-shaped floating city that will house 20,000 people in a lagoon near the country’s capital.

“Called Maldives Floating City, the development will contain 5,000 low-rise floating homes floating within a 200-hectare lagoon in the Indian Ocean. As sea levels rise, so too will the city, which will be built upon a series of hexagonal-shaped floating structures.

“In the Maldives, 80 per cent of the country sits less than one metre (three feet) above sea level. With the Maldives islands predicted to be uninhabitable by 2100 due to rising sea levels, the government of the Maldives hopes to offer up to 20,000 locals and foreigners the opportunity to move to the floating city as early as 2024.

“Construction is planned to begin later this year on the development, which will be 10 minutes by boat from the Maldivian capital Male.

” ‘This first-of-its-kind island city offers a revolutionary approach to modern sustainable living perched against a backdrop of the azure Indian Ocean,’ said the studio. …

“Maldives Floating City is among a number of floating city proposals, including Oceanix Busan by architecture firms BIG and Samoo and tech company Oceanix that are designed to offer a housing solution to rising sea levels and global temperature increases.

“However, developer Dutch Docklands claims that none have been attempted on this scale and at this speed with full governmental support.

” ‘While attempts at floating cities have been tried before, none have featured Maldives Floating City’s most compelling selling points: full-scale technical, logistical and legal expertise,’ explained Dutch Docklands.

“The development, which is set to be fully completed by 2027, will be composed of a series of hexagonal islands modeled on the geometric shapes of a local coral called brain coral. When combined and viewed from above the development will resemble a brain. …

“The living platforms will support houses, hotels, restaurants, shops, a hospital, a school and a government building. …

” ‘As a nation at the front lines of global warming, the Maldives is perfectly positioned to reimagine how humankind will survive — and, indeed, thrive — in the face of rising seas and coastal erosion,’ said the Dutch Docklands.

” ‘Inspired by traditional Maldivian sea-faring culture and developed in close cooperation with Maldivian authorities, Maldives Floating City homes will eventually be joined by hotels, restaurants, stylish boutiques and a world-class marina.’

“The Intergovernmental Panel on Climate Change (IPCC)’s Sixth Assessment Report 2022, states that small island nations such as the Maldives may become completely uninhabitable as the world is on track to warm by two to three degrees this century.

” ‘The world faces unavoidable multiple climate hazards over the next two decades with global warming of 1.5°C (2.7°F)’ the report by the United Nations’ climate change panel said. ‘Even temporarily exceeding this warming level will result in additional severe impacts, some of which will be irreversible. Risks for society will increase, including to infrastructure and low-lying coastal settlements.’

“Viable solutions for urban development into the ocean listed in the report include elevating houses on stilts and creating ‘amphibious architecture’ that can float on the surface of rising floodwater.”

Oy. I try to find hopeful stories for the blog, but I think I failed on this one. We really need to reverse what we’ve done. I know climate is not the same as weather, but the extremes of weather we are seeing should convince even nonbelievers that something is going on. I left for my walk at 5:15 am today to “beat the heat.” It was already 80F (26.6 C)!

Finnish researchers Markku Ylönen and Tommi Eronen, who came up with the sand-battery idea. Don’t these guys look just like the kind of young people you’d expect to tackle something impossible?

The big challenge for renewable energy sources like solar and wind has always been storage. Where is there a battery big enough and powerful enough to store the energy until it’s needed?

Bring on a couple wiz kids who think about daunting problems like global warming and overdependence on Russian gas.

Matt McGrath writes at the BBC, “Finnish researchers have installed the world’s first fully working ‘sand battery,’ which can store green power for months at a time. …

“Using low-grade sand, the device is charged up with heat made from cheap electricity from solar or wind. The sand stores the heat at around 500C (~932 degrees Fahrenheit), which can then warm homes in winter when energy is more expensive.

“Finland gets most of its gas from Russia, so the war in Ukraine has drawn the issue of green power into sharp focus. It has the longest Russian border in the EU and Moscow has now halted gas and electricity supplies in the wake of Finland’s decision to join NATO.

“Concerns over sources of heat and light, especially with the long, cold Finnish winter on the horizon are preoccupying politicians and citizens alike. But in a corner of a small power plant in western Finland stands a new piece of technology that has the potential to ease some of these worries.

“The key element in this device? Around 100 tonnes of builder’s sand, piled high inside a dull grey silo.

“These rough and ready grains may well represent a simple, cost-effective way of storing power for when it’s needed most.

“Because of climate change and now thanks to the rapidly rising price of fossil fuels, there’s a surge of investment in new renewable energy production. But while new solar panels and wind turbines can be quickly added to national grids, these extra sources also present huge challenges.

“The toughest question is about intermittency — how do you keep the lights on when the sun doesn’t shine and the wind doesn’t blow? …

“The most obvious answer to these problems is large-scale batteries which can store and balance energy demands as the grid becomes greener.

“Right now, most batteries are made with lithium and are expensive with a large, physical footprint, and can only cope with a limited amount of excess power.

“But in the town of Kankaanpää, a team of young Finnish engineers have completed the first commercial installation of a battery made from sand that they believe can solve the storage problem in a low-cost, low impact way.

” ‘Whenever there’s like this high surge of available green electricity, we want to be able to get it into the storage really quickly,’ said Markku Ylönen, one of the two founders of Polar Night Energy who have developed the product.

“The device has been installed in the Vatajankoski power plant, which runs the district heating system for the area.

“Low-cost electricity warms the sand up to 500C by resistive heating (the same process that makes electric fires work). This generates hot air which is circulated in the sand by means of a heat exchanger.

“Sand is a very effective medium for storing heat and loses little over time. The developers say that their device could keep sand at 500C for several months.

“So when energy prices are higher, the battery discharges the hot air which warms water for the district heating system which is then pumped around homes, offices and even the local swimming pool.

The idea for the sand battery was first developed at a former pulp mill in the city of Tampere, with the council donating the work space and providing funding to get it off the ground.

” ‘If we have some power stations that are just working for a few hours in the wintertime, when it’s the coldest, it’s going to be extremely expensive,’ said Elina Seppänen, an energy and climate specialist for the city. ‘But if we have this sort of solution that provides flexibility for the use, and storage of heat, that would help a lot.’ …

“One of the big challenges now is whether the technology can be scaled up to really make a difference — and will the developers be able to use it to get electricity out as well as heat? The efficiency falls dramatically when the sand is used to just return power to the electricity grid. …

“Other research groups, such as the US National Renewable Energy Laboratory are actively looking at sand as a viable form of battery for green power. But the Finns are the first with a working, commercial system, that so far is performing well, according to the man who’s invested in the system.

” ‘It’s really simple, but we liked the idea of trying something new, to be the first in the world to do something like this,’ said Pekka Passi, the managing director of the Vatajankoski power plant.”

One of the aspects of this approach that I like best is that it doesn’t use lithium, a “blood mineral,” the mining of which often hurts local communities.

Working with his team and villagers, retired forest chief Hikmet Kaya has helped create a forest on once-barren land in Turkey.

Around the world, people have learned that planting trees can help us fight back against global warming. But it’s not as easy as sticking them in the ground. You have to ensure they live. And thrive.

Jessica Stewart reports on one initiative at My Modern Met, “Hikmet Kaya has proved that good intentions and hard work can yield big rewards. The retired Turkish forest management chief has posed proudly in front of the barren land that he and his team have transformed into a lush forest.

“He began his career in the town of Sinop in 1978 and while he retired 19 years later, his legacy has continued to grow — literally.

“Working together with his team and villagers, he brought in and planted 30 million saplings over the course of his tenure. Long after his retirement, these trees have continued to grow; and today, this barren stepped land has undergone an incredible transformation. … Needless to say, he admits he’s very happy with the results.

“It’s a wonderful example to set for the rest of the country. According to Global Forest Watch, Turkey has seen a 5.4% decrease in tree cover since 2000. … Combatting deforestation often comes down to governmental policy changes, which makes it important for individuals to know who they are voting for and to make sure their environmental concerns are heard. Still, that hasn’t stopped people from taking matters into their own hands and taking action.”

There’s a tree maven in India who worked without help. You may have read about him. I’ll share Andrei Tapalaga‘s History of Yesterday story in case you missed the news.

“When talking about saving the environment, most people come with the comment of ‘how much difference will I make?’ … In this article, I want to present a man who has defied any kind of odds and showed the world that if you set your mind to something it will become possible.

“Jadav ‘Molai’ Payeng spent 40 years of his life planting trees, gaining the nickname of ‘Forest Man’ in India for transforming a [barren island] into a forest. [At this point] Payeng had covered 1,400 acres with trees. There is no exact number of trees as he never kept track, but we are looking at around 1.5 million trees planted in 40 years.

“Payeng was born in 1963 near the small rural town of Jorhat, India. From a young age, he saw a small island near the coast of the Brahmaputra River suffering from erosion. In many of his interviews taken by the media in India, he described that he had spent some of his [childhood] playing in that forest and it was heartbreaking seeing its vegetation slowly die.

“That is why in 1979, when Payeng was 16 years of age, he decided to plant at least one tree a day for as long as he lives, calling it giving back to Mother Nature. … The start to this incredible journey was difficult, not only [considering] the road ahead, but it was simply difficult to find tree seeds to plant. His vision was not to plant only one type of tree, but many different types. …

“As the years went by, the problem of finding seeds was solved as the trees he had planted years ago started to give seeds. With more seeds, he was able to plant even more trees every day. The island is surrounded by a flowing river, so the water supply was never a problem. …

“There are many people out there just like Payneg who have dedicated most of their life toward an honorable cause but rarely get noticed. The media in India actually discovered Payeng by mistake when in 2008, a herd of over 100 wild elephants strayed into the forest he had created.

“Payeng notified the forest department about the elephants and they thought he was crazy at first as there was no forest on the island. Upon the forest department’s inspection of the island, the community around Jorhat told them about Payeng’s efforts, at which point the media from India bombarded Payeng. [He] was also made an official forester for the forest he had created on Majuli island.

“In 2012 Payeng was interviewed by the Times, where he confessed that he had always asked for help but no one wanted to assist him. … Now the island is greener than ever whilst being inhabited by all sorts of wildlife from rabbits to tigers and even rhinos. The plantation of trees had slowed down as Payeng is becoming old and tired. However, he is trying to make his children continue what he had started.”

These eelgrass seeds are fresh from the sea.
Mexico’s indigenous Comcáac people have managed to protect 96% of the precious eelgrass that grows in their region.

I have long known about beach grass and how it can hold the dunes and protect the land in a hurricane. I know about how easily the roots die if you walk on beach grass and why, when “Keep Off the Dunes” signs aren’t obeyed, houses wash away.

But I’m learning there’s another fragile grass that helps the environment. This one lives in the sea and captures carbon.

Sam Schramski has the story at Public Radio International’s the World.

“At a two-day festival on the coast of northern Mexico [last] month, scientists, chefs and local residents gathered to celebrate eelgrass — a unique type of seagrass that grows in the Gulf of California. 

“Seagrass is on the decline in the world’s oceans, but the Indigenous Comcáac people who live in the region have managed to protect the eelgrass that grows in their waters. 

” ‘From my parents, I learned about medicinal plants and the songs of plants, as well as about traditional foods,’ said Laura Molina, who is Comcáac.

“She remembers how her mom made tortillas out of flour ground from eelgrass seeds known as xnois in Comcáac language, a mix between wild rice and nori seaweed. 

Seagrass is getting a lot of attention these days because of its capacity to store carbon, estimated to sequester up to half the so-called ‘blue carbon’ in the world’s oceans and coastal ecosystems — putting it on par with global forests.

“Ángel León, a Spanish chef and owner of Aponiente restaurant, has made it his personal mission to protect threatened seagrass beds off the Spanish coast. He’s interested not only in the plant’s environmental benefits but also its culinary potential in the kitchen as a nutrient-rich superfood. …

“Seagrass is down about 30% globally since the late 1800s. Through León’s restaurant and related nongovernmental organizations, he has heavily financed seagrass restoration projects.” More at the World, here. Listen to the audio version there.

Kendal Blust at Fronteras also wrote about the festival: “In the small Comcaac village of Punta Chueca, on the Sonoran coast of the Gulf of California, a group of women gathered around a white sheet piled high with dried zostera marina, or eelgrass.

“One woman sang an ancestral song dedicated to the plant, known as hataam, as others beat the dried eelgrass and rubbed it between their palms to remove its small, green seeds. Xnois, as the seeds are known in the Comcaac language, cmiique iitom, are an ancestral food.

“ ‘The Comcaac are the only people, the only Indigenous group, that consumes the seed,’ said Erika Barnett, a Punta Chueca resident who has been heavily involved in restoration efforts.

“Eelgrass seed has been a part of their culture for millennia, she said. Traditionally, the flour was used to make tortillas and a hot drink combined with honey and sea turtle oil. And because it’s quite filling, it used to be carried by Comcaac during sea journeys. …

“Barnett said her great-grandparents were probably the last members of her family to collect and eat the xnois seeds. Her father, now 76, last tasted it when he was just 7.

” ‘That’s was the last time he ate it,’ she said. ‘It’s very ancient, but it’s no longer eaten like it used to be, and most younger people have never tasted it. So this effort is really rescuing our culture.’ …

“Now, Barnett is part of a team working to bring the tradition back to their community — both because of the plant’s nutritional value and its ecological benefits. Eelgrass creates habitat for sea turtles and fish, protects the coastline and captures carbon.

“ ‘It’s important for us to revive these traditions so they can be passed on to future generations,’ she said. ‘But I think we need to show the community that it can be done, first. That it’s hard, but we can harvest the seeds.’

“So for weeks in April, a group of women and girls harvested eelgrass the way their ancestors would have. They waded into the sea to collect plants floating near the shore, then dried, thrashed and winnowed them. …

“ ‘One of the missions of Aponiente is to look to the sea with hunger,’ said Greg Martinez, a chef and biologist. … Martinez said the restaurant is committed to discovering the gastronomic potential in the ocean, both for our health and for the planet.

“And eelgrass has a lot of potential. For one thing, it captures and holds carbon below the water’s surface. Known as blue carbon, it can help mitigate climate change.

“ ‘But it doesn’t only sequester carbon,’ Martinez said. ‘It also protects coastlines. It serves as a habitat for thousands of different species that come to breed in their protection. It buffers waves so if you have a tsunami or another storm it protects the coastline in that way as well.’

“Despite the swath of ecosystem services seagrasses provide, however, seagrass beds currently are disappearing from the world’s oceans, he said. And that makes it especially important to protect the abundant meadows in the Canal del Infiernillo, a channel between the coast and the massive Tiburon Island that is entirely within Comcaac territory.”

Camryn Stewart, 14, and Naomi Bell (right) open the salmon season on Scotland’s River Dee with the first casts.

So many good people trying to make the world better! Each one has their own area of action. It may be health, sports for kids, peace, housing, justice, the environment, art, teaching school. You name it. Today’s story is on people doing something about the effects of global warming where they live — along Scotland’s rivers.

Severin Carrell reports at the Guardian that “millions of trees are being planted beside Scotland’s remotest rivers and streams to protect wild salmon from the worst effects of climate heating.

“Fisheries scientists have found rivers and burns in the Highlands and uplands are already too warm in summer for wild Atlantic salmon as they head upstream to spawn, increasing the threat to the species’ survival.

“Fisheries on the River Dee in Aberdeenshire, one of the country’s most famous salmon fishing rivers, have planted 250,000 saplings along key tributaries. They plan to plant a million in the Dee’s catchment by 2035. …

“In 2018, the year Scotland recorded the lowest rod catch for salmon since records began, climatic changes meant water temperatures in 70% of salmon rivers were too warm for at least one day that summer. They exceeded 23C [73.4 Fahrenheit], a temperature that induces stress and behavioural change. …

“Marine Scotland scientists found that only 35% of Scotland’s rivers, which stretch for 64,000 miles (103,000km), have adequate tree cover.

“Lorraine Hawkins, the river director for the Dee District Salmon Fishery Board, a statutory body, said: ‘These rivers and burns are the nursery grounds for young fish and it’s the young fish which will be affected by summer temperatures – their feeding and growth rates are affected. If it gets hotter, we will see fish dying.’

“Fishery boards across Scotland have similar tree-planting programs, to provide essential shade to lower water temperatures. Many will be fenced off to prevent the saplings from being eaten by deer. Hawkins said these projects improved the overall health and biodiversity of rivers across the uplands, increasing insect life, leaf fall, managing essential nutrients and flood control.

“Alan Wells, the director of Fisheries Management Scotland, an industry body, said climate forecasts were clear that water temperatures would continue to climb, even if governments succeed in limiting climate heating. …

“He said, ‘This will get worse. We need to grow trees now to create that cooling shade.’

“The dramatic decline in wild salmon numbers is blamed on numerous factors: climate change affecting food availability; weirs and other obstructions in rivers; predation by soaring seal populations; sea lice attracted by fish farms; bycatch by trawlers at sea and poor river quality. Wells said that while Scottish ministers were proposing new conservation strategies, he remained frustrated with the slow pace of change.

“The Dee marked the start of its angling season [in February] by inviting two female anglers who won a fundraising competition last year to make the first cast, an annual ceremony at Banchory. …

“Camryn Stewart, 14, one of the first cast fishers, said she had been brought up fishing by her parents, Deirdre and Jim. The sport is targeting women and children as it strives to expand its participation and appeal. …

“ ‘I have been surrounded by people who fish, and I’ve wanted to fish all my life,’ she said. ‘We need more people fishing. … We gain so much from it. Just being outside and being in the wild. Even if you don’t catch anything, you come back from the day fulfilled.’ ”

Flanders Moss in Scotland has seen the return of key bog plants such as sphagnum (peat moss) and cottongrass — so important now that we know bogs can store the carbon we don’t want in the atmosphere.

My father-in-law sold peat moss, among other agricultural products, for his entire career. He usually got the peat from Canada, although other people source it from places like Germany and Ireland. In Moat, Ireland, our friend James Hackett relied on peat for warming the house. (Burning it was not the best thing for his health.)

Today’s story is about Scotland’s heightened focus on protecting peat bogs so they can store carbon and fight global warming.

Phoebe Weston reports at the Guardian, “Flanders Moss bog is slumped on the flat, farmed landscape of the Carse of Stirling in Scotland like a jelly fungi. It wobbles when you walk on it, and a metal pole goes down eight metres before reaching hard ground. This lowland-raised bog is a dome of peat fed mainly by rainfall and it acts like a single organism – the whole thing has to be looked after for any part to be in really good shape. If it is drained in one area it will affect the water level across the entire bog.

“For much of human history peat bogs have been thought of as wastelands. This 860-hectare [~2,200 acres] site has been hacked away and drained since the early 1800s to make space for fertile farmland below. …

“It is now recognized that peat bogs are among the greatest stores of carbon and, after decades of restoration, the holes in the peat at Flanders Moss have been patched up. Areas that used to be purple with heather are turning green as key bog plants such as sphagnum (peat moss) and cottongrass come back. The bog rises out of the land like a sponge and ‘breathes’ as changes in the weather and water level cause it to swell and contract.

“Researchers in Scotland are tracking ‘bog breathing’ using the latest satellite technology that can detect just a few millimetres of change. … Thanks to the restoration work, the water table has risen [and] is now at the surface. As the bog draws in water from the surrounding land, it helps manage flood risk. Flanders Moss bog has removed [about 2,200 acres] from the Forth catchment, reducing flooding downstream. …

“The Scottish government-funded Peatland Action project, which started in 2012, is helping revive 25,000 hectares [~61,776 acres] of degraded peatland. In 2020, the Scottish government committed [about $300 million] over 10 years to bog restoration in a bid to lock carbon in the land. …

“It takes about a month to process the satellite data for a third of Scotland, which is available through the Copernicus Open Access Hub. The technology is still in development but is likely to be cheaper than ground-based mapping. …

“Despite these restoration efforts, Flanders Moss is still a net emitter of carbon. … Stopping these emissions and preventing further degradation are the primary objectives of the restoration project.

“Bogs work on a different timeframe than humans. They form slowly … taking up to 1,000 years to grow one metre. But [David Pickett, who manages the site with his National Nature Reserve] team has jump-started recovery. ‘We’ve done most of the big work here,’ he says. ‘Now, it’s a question of waiting. The process of fixing this site will last 100 years, and the benefits of work being done now will only be seen by the next generation.’

“It’s easy to see why bogs weren’t popular. They are stores of partly decayed organic matter, which are too acidic and devoid of nutrients to support healthy trees. But this bog is colorful and has a fresh, earthy smell. As well as being a fantastic store of carbon, this ancient, watery land – healthy peat is about 90% water – is also rich in wildlife, including rare lizards, dragonflies and even snakes.

“ ‘There isn’t headline sexy stuff like puffins and seals but you go around the boardwalk and it’s a fantastic place,’ says Pickett. ‘I always used to think bogs must have been named on a Friday after a really bad week. We’re trying to change the perception of bogs but it’s a hard sell.’ ”

Biospheres in Arizona gather ancient wisdom to aid future generations.

Now that we know human activity is the main reason for dangerous global warming, it’s time to turn to indigenous tribes and learn to step more lightly on Plant Earth. That’s the thinking behind a biosphere project in Arizona.

Samuel Gilbert reports at the Washington Post, “Indigenous peoples have known for millennia to plant under the shade of the mesquite and paloverde trees that mark the Sonoran Desert [in Arizona], shielding their crops from the intense sun and reducing the amount of water needed.

“The modern-day version of this can be seen in the Santa Catalina Mountains north of Tucson, where a canopy of elevated solar panels helps to protect rows of squash, tomatoes and onions. Even on a November afternoon, with the temperature climbing into the 80s, the air under the panels stays comfortably cool.

“Such adaptation is central to the research underway at Biosphere 2, a unique center affiliated with the University of Arizona that’s part of a movement aimed at reimagining and remaking agriculture in a warming world. In the Southwest, projects are looking to plants and farming practices that Native Americans have long used as potential solutions to growing worries over future food supplies. At the same time, they are seeking to build energy resilience.

“Learning from and incorporating Indigenous knowledge is important, believes Greg Barron-Gafford, a professor who studies the intersection of plant biology and environmental and human factors. But instead of relying on tree shade, ‘we’re underneath an energy producer that’s not competing for water.’

“On both sides of the Arizona border with Mexico, scientists are planting experimental gardens and pushing the potential of an ‘agrivoltaic’ approach. Thirsty crops such as fruits, nuts and leafy greens — which require elaborate irrigation systems that have pulled vast quantities of water from underground aquifers and the Colorado and other rivers — are nowhere to be found. …

“Southern Arizona is an epicenter of the movement not just because of the intense environmental pressures that the region faces but because of the presence of the Tohono O’odham Nation southwest of Tucson.

“The Tohono O’odham have farmed in the Sonoran Desert for several thousand years. Like many Indigenous groups, they now are on the front lines of climate change, with food security a paramount concern. Their expansive reservation, nearly the size of Connecticut, has just a few grocery stores. It is a food desert in a desert where conditions are only getting more extreme.

“Since the early 1970s, a group of Nation members have run the San Xavier Cooperative Farm and grown ‘traditional desert cultivars’ in accordance with their ancestral values — particularly respect for land, water and plants.

“Sterling Johnson, a member of the Tohono O’odham Nation, has worked for the past decade to share that expertise broadly. His partner, Nina Sajovec, directs the Ajo Center for Sustainable Agriculture, a Native American-governed food justice organization that several years ago founded its own seed bank and already has distributed over 10,000 seeds to farmers.

“ ‘We’re all about using what is out there,’ Sajovec said. Among the center’s heirloom varieties: 60-day corn, a fast-maturing desert-adapted vegetable, and the tepary bean, a high-protein legume particularly suited to the climate because of leaves that can fold to withstand direct sunlight during the peak of summer.

“Johnson captures precipitation during the Arizona monsoon season to sustain crops on his field in the desert lowlands. ‘It’s using the rainwater,’ he explained, ‘using the contour lines, using your environment and nature to grow food.’ …

“Perhaps even more daunting than the rising temperatures of climate change are the water shortages that many parts of the world will confront. In Tucson, the Santa Cruz River is now dry because of too much diversion and burgeoning demand, according to Brad Lancaster, an expert on rainwater harvesting.

“ ‘The majority of the water that irrigates landscapes and Tucson and Arizona is not local water’ but tapped from the Colorado River, Lancaster said. Unless severe drought conditions reverse and the river level improves, mandatory federal cutbacks mean farmers will lose a significant amount of that critical resource starting next year.

“ ‘The goal is how can we use rainwater and storm water, passively captured, to be the primary irrigator,’ said Lancaster, who lives in a local neighborhood that has been transformed through passive water harvesting into an ‘urban forest,’ with wild edible plants such as chiltepin pepper and desert hackberry lining the sidewalks.

“He is planning a similar system at Tumamoc Resilience Gardens, using basins and earthen structures to spread water across the landscape and reduce channelized flows. Nabhan, who also is involved in the site’s design, sees it as replicable and, more importantly, scalable. …

“ ‘We’ve had 5,000 years of farmers trying out different strategies for dealing with heat, drought and water scarcity,’ said [Gary Nabhan, an ethnobotanist and agrarian activist who focuses on plants and cultures of the Southwest], walking around his own creation at his home in Patagonia, a small town about 18 miles north of the Mexico border. The fenced space holds 40 species of agave, three species of sotol, prickly pear and other varieties of cactuses and succulents.

“ ‘The key concept,’ he said, ‘is that we’re trying to fit the crops to the environment rather than remaking the environment.’ ”

Author Tsitsi Dangarembga has joined the Future Library, offering a work that won’t be read for 100 years. 

There are many ways artists can highlight how global warming is hurting the planet. Katie Paterson, for example, once created an installation that allowed people to listen in on the sound of glaciers melting. Now she has come up with the idea of a Future Library in hopes that it will still exist in 100 years so that people can read the works of the celebrated authors who have joined the project.

Alison Flood reports on one such author at the Guardian. “Tsitsi Dangarembga made the Booker shortlist for her most recent novel, This Mournable Body, the story of a girl trying to make a life in post-colonial Zimbabwe which was praised as ‘magnificent’ and ‘sublime.’ Her next work, however, is likely to receive fewer accolades: it will not be revealed to the world until 2114.

“The Zimbabwean writer is the eighth author selected for the Future Library project, an organic artwork dreamed up by the Scottish artist Katie Paterson. It began in 2014 with the planting of 1,000 Norwegian spruces in a patch of forest outside Oslo. Paterson is asking one writer a year to contribute a manuscript to the project – ‘the length of the piece is entirely for the author to decide’ – with Margaret Atwood, Ocean Vuong and Karl Ove Knausgård already signed up. The works, unseen by anyone but the writers themselves, will be kept in a room lined with wood from the forest in the Deichman library in Oslo. One hundred years after Future Library was launched, in 2114, the trees will be felled, and the manuscripts printed for the first time.

“The artwork ‘perfectly expresses my yearning for a human culture that centres the earth’s sustainability,’ said Dangarembga. ‘I share with many other dwellers of our beautiful planet a deep sense of concern for our home’s wellbeing.’ …

“The author, whose acclaimed debut Nervous Conditions (1988) was the first novel written in English by a black woman from Zimbabwe, said she was already “settling on the story” she would tell. She was not worried about the fact that she will never know how her writing is received.

“Paterson said that Future Library was ‘honoured’ to include Dangarembga. … ‘Tsitsi Dangarembga’s words have shaped the world.

” ‘I don’t think of myself in those terms,’ Dangarembga said. ‘So it’s really a great honour, I’m very pleased about it.’

Saul Griffith’s latest venture, Otherlab, is a research company reminiscent of the “invention factory” created by Thomas Edison.

Here’s an Australian inventor who aims to stop global warming. I especially like his ideas about a substitute for lithium batteries — not just because it could save money but because lithium and other rare minerals are the new “blood diamonds.” Mining them is bad for Nature, bad for communities.

Rachel Pannett writes at the Washington Post, “During a TED talk, Australian inventor Saul Griffith wanted to show his audience how much a person’s individual choices can affect the planet.

“The person, in this case, was himself. And so, the tall engineer with tousled brown hair pulled up a chart on a big screen behind him on the stage.

“On display was an exhaustive audit of his personal energy impact, calculating the carbon footprint of every action in his life down to his underwear, toilet paper and taxes.

“The founder of a wind power company and a dedicated bicycle commuter, Griffith was ashamed to discover that he was consuming much more power than the average American. In short, a planet hypocrite, he told his audience. …

“Since that TED talk 10 years ago, Griffith’s San Francisco lab has attracted $100 million in capital from investors and spun out a dozen companies.

“The 47-year-old, who won a MacArthur ‘genius’ grant in 2007 for his prodigious inventions ‘in the global public interest,’ from novel household water-treatment systems to an educational cartoon series for kids, has spent the past decade working to solve climate change through technology. His solution: mass electrification.

“While most environmentalists have taken aim at the fossil fuel industry, Griffith wants to decarbonize each American household — replacing every gas cooktop, furnace and hot water heater with electric devices. Otherwise, he says, efforts to reach net-zero carbon emissions will fall short.

“Most of Griffith’s tinkering happens in a nearly century-old former factory in San Francisco’s Mission District. … From every available space on the ceiling and walls, Griffith’s team has hung bicycles — from cargo bikes to a four-seater electric model.

“Otherlab, which Griffith co-founded more than a decade ago, is where the Australian and two dozen other scientists are trying to find a way to stop global warming.

“One of the lab’s current projects aims to radically redesign offshore wind platforms. Another team is designing a solar-powered scooter set for launch this year. They also designed a tracker system that helps solar panels follow the sun’s path through the day.

“ ‘Things don’t stay on paper very long,’ said Joanne Huang, Otherlab’s special projects lead, who joined the company in 2019. ‘It is like a build-it-and-see kind of place. It’s very fun in that way.’ …

Griffith believes climate change is solvable, and he imagines a cleaner future that looks better than what we have now. …’There is every reason to believe the future can be awesome.’

“In the first-floor workshop, Huang and Hans von Clemm, an engineer, were recently working on modular cubes designed to stack neatly in the corner of a person’s garage to store excess energy from rooftop solar systems. The heating and storage systems are being tested in several homes in California, including Huang’s. Their hope is to store electricity from rooftop solar panels for far less than the cost of a lithium battery — making the technology accessible to more people. …

“For the task, Griffith has assembled an eclectic team. Von Clemm is a former ski instructor; Huang was a competitive snowboarder.

“Von Clemm, who joined Otherlab as an intern in 2016, remembers the day he interviewed for the job. Griffith asked to see his hands, which were calloused and covered in cuts. The week before, von Clemm had been building a knife drawer for his mom. ‘All right,’ Griffith said approvingly.

“He then handed the young engineering student a piece of paper and a pen and asked him to draw a working bicycle in 60 seconds. Von Clemm said his hands were shaking. When he finished, Griffith declared: ‘Okay, you can start tomorrow.’

“Griffith’s vision for addressing the devastating impact of climate change bucks tradition. Instead of just focusing on shutting down coal and gas-fired power plants and polluting industries and switching to renewable power generators, he wants to also focus on suburban life. … There is little use in having wind or solar power if your stovetop, furnace and water heater are powered by gas.

“Griffith acknowledges this could be a tough task — furnaces are not easy to swap out like appliances such as refrigerators: Typically, you replace them only when they are broken. …

“ ‘We need a Cambrian explosion of local experiments of how to locally solve the problem,’ said Griffith, whose book, “Electrify: An Optimist’s Playbook for Our Clean Energy Future,” will be published in October.”

Burning peat increases global warming, which is why commercial operations are closing, but undisturbed bogs have always been great for keeping carbon
from the atmosphere.

My father-in-law was in the peat moss business back in the day. The Philadelphia company he worked for and later ran was called I.H. Nestor. It sold peat mostly for agriculture, but you may know that peat was also burned for heat, especially in Ireland. My friend, the late great James Hackett, and his family always heated their home with peat, with unfortunate consequences for their health.

Today’s story is about the historical value of peat bogs, an aspect that has been mostly unrecognized until now.

Chris Mooney writes at the Washington Post, “Long before the era of fossil fuels, humans may have triggered a massive but mysterious ‘carbon bomb’ lurking beneath the Earth’s surface, a new scientific study suggests. If the finding is correct, it would mean that we have been neglecting a major human contribution to global warming — one whose legacy continues.

“The researchers, from France’s Laboratory of Climate and Environmental Sciences and several other institutions across the globe, suggest that beginning well before the industrial era, the mass conversion of carbon-rich peatlands for agriculture could have added over 250 billion tons of carbon dioxide to the atmosphere. That’s the equivalent of more than seven years of current emissions from the burning of fossil fuels for energy.

“ ‘Globally [peatlands] are only 3 percent of the land surface but store about 30 percent of the global soil carbon,’ said Chunjing Qiu, a researcher at the laboratory, a joint institution supported by French government research bodies and the Versailles Saint-Quentin University, and the first author of the study published Friday in the journal Science Advances.

“The new finding of an ‘ignored historical land use emission’ suggests that even now, we lack a complete understanding of how the Earth’s land surfaces are driving and modulating the warming of the planet. … Scientists have long worried about the potential for massive amounts of carbon being released by northern permafrost, where ancient plant remains lie in a kind of suspended animation beneath the surface. But the peat threat is very similar; in fact, peatlands overlap considerably with permafrost regions.

“Peatlands are a particular type of wetland, one in which dead plant matter does not fully decay due to the watery conditions, and thus accumulates.

In its normal state, peat slowly pulls carbon out of the atmosphere — unless you disturb it.

“If a peatland is drained — as has occurred for many centuries to promote agriculture, especially the planting of crops — the ancient plant matter begins to decompose, and the carbon it contains joins with oxygen from the atmosphere. It is then emitted as carbon dioxide, the principal greenhouse warming gas. …

“To try to get around the problem of missing historical records, the new study simulates the Northern Hemisphere (outside of the tropics) over thousands of years to determine where peat would have likely developed. Over time, the computer model will begin to include growing agricultural activities. It can then be used to analyze different scenarios for how frequently such developments may have occurred on peatland.

“In a middle-of-the-road scenario, where humans would have regularly grown crops on peatlands, the study finds that some 70 billion tons of carbon (over 250 billion tons when converted to carbon dioxide) would have been lost from the soil.

“Importantly, the analysis does not cover all the peatlands across the globe: It only considers Northern Hemisphere peatlands from the year 850 CE onward. Massive losses of tropical peat are even now occurring in countries like Indonesia and Malaysia, for instance, so global losses will be higher. …

“The study is ‘a broad modeling approach with many assumptions, which can all be individually questioned and debated,’ added Hans Joosten, who leads a peat research group at the University of Greifswald in Germany. ‘But the overall message that remains is that drainage of only a small part turns the entire northern peatland resource into a net carbon source.

‘Though peatlands indeed are carbon sinks in their pristine state, they should also be seen as carbon bombs, which explode whenever they are damaged. Keep them wet!’ …

“The new work underscores that major gaps remain in how much we know about the human contribution to climate change, even as we are trying to halt it. With poor understanding about peat locations, and poor reporting about land conversion, experts say, many countries can’t fully account for peat emissions even now. That could raise questions about what has been happening in their land-use sector.”

From the
Christian Science Monitor news roundup: “Managing director Kimani Muturi shows off a TexFad hair extension made from banana trunk fibers near Kampala, Uganda, April 3, 2021. When finished using it, consumers can compost the product. The company also makes rugs and other handwoven textiles.

When in the air-conditioner season I stop to think about how much we all depend on fossil fuels, I worry that we will never be able to halt global warming. But then I read stories from around the world about inventive people doing what they can, and I remember the underlying wisdom of “one and two and 50 make a million.”

Lindsey McGinnis at the Christian Science Monitor has scoured the news media for signs of progress in a variety of areas, including the environment.

“Researchers from the University of Maryland and Yale have made a breakthrough in the search for sustainable plastic alternatives, developing a wood-based bioplastic that disintegrates in a few months. … The new bioplastic is created by using a biodegradable solvent to deconstruct wood powder found at lumber mills into a slurry, which can then be shaped into common plastic products, such as shopping bags and other packaging.

“Other experimental bioplastics have often lacked the strength to compete with petroleum-based plastics, but the scientists say their product showed high mechanical strength during tests, the capacity to hold liquid, and resistance to ultraviolet light. At the end of a product’s life, the bioplastic will quickly decompose in soil, or can be re-slurried and used again. Source: New Atlas, Nature Sustainability

“A startup in Uganda is making consumer products from edible banana plant material that would otherwise go to waste. Uganda is sub-Saharan Africa’s top producer of bananas and plantains, with an estimated 75% of all farmers growing some form of banana. They typically leave the stalks to rot after harvesting fruit. That’s where TexFad saw an opportunity. The company, which launched in 2013 and employs 23 people, runs the stalks through a machine to create long fibers, hangs the leathery strands to dry, and uses the material to create products such as carpets.

“Last year, the company made $41,000 in sales, and the managing director expects TexFad to double production in 2021 to 2,400 carpets, some of which will be exported to customers in the United Kingdom, Canada, and the United States for the first time. The company also creates hair extensions (used ones can be composted) and is working on a process to soften the fibers for use in clothing. Source: Interesting Engineering, Reuters

“A global network is helping reroute dangerous refrigerants before they leak into the atmosphere. Freezers and refrigerators have housed some of the most potent greenhouse gases, including the compound known as R12, a chlorofluorocarbon with roughly 10,000 times the destructive potential of CO2. The refrigerants pumped into modern units are better, but still pose global warming potential. When disposed of improperly – either knowingly or unknowingly – these gases are released into the atmosphere and contribute to climate change.

“Tradewater, a company that collects and destroys greenhouse gases and sells the carbon offset credits, is coordinating with governments and businesses around the world to dispose of the gases safely. Its teams are sometimes called ‘chill hunters’ or ‘ghostbusters’ for the way they track and trap the gases, transferring them from discarded refrigerator cylinders into a large container. Tradewater then incinerates the recovered gases. The group reports that 4 million to 5 million metric tons have been kept out of the atmosphere so far. Ángel Toledo has run a waste disposal plant on the edge of Guatemala City for 16 years, but only dealt with refrigerant gases since 2018. ‘It’s like a dream, helping the environment … [by preventing these] gases from reaching the atmosphere.’ Source: BBC.”

Asparagopsis is a species of Red Algae that can fight global warming. When eaten by cows, it releases bromoform, which reduces methane production and limits how much CO2 goes into the atmosphere.

It isn’t hard for me to give up eating beef — but milk? For one thing, my doctor wants me to drink it. I do know that cows and other livestock are not helping with our global-warming problem, and that’s a worry. Here’s something that could help.

Tatiana Schlossberg writes at the Washington Post, “One of the most powerful weapons in the fight against climate change is washing up on shorelines around the world, unnoticed by most beachgoers. It’s seaweed. Specifically, Asparagopsis taxiformis and Asparagopsis armata — two species of a crimson submarine grass that drifts on waves and tides all around the world’s oceans.

“It doesn’t seem like much, but it could practically neutralize one of the most stubborn sources of a powerful greenhouse gas: methane emissions from the digestive processes of some livestock, including the planet’s 1.5 billion cows, which emit methane in their burps.

“Reducing methane from livestock, and cows in particular, has long been a goal of scientists and policymakers but is especially tricky: How do you change a fundamental fact of animal biology in an ethical way that doesn’t affect milk or meat?

“In lab tests and field trials, adding a small proportion of this seaweed to a cow’s daily feed — about 0.2 of a percent of the total feed intake in a recent study — can reduce the amount of methane by 98 percent. That’s a stunning drop when most existing solutions cut methane by about 20 or 30 percent.

“Meanwhile, growing seaweed used for the feed supplement could also help sequester carbon dioxide, another greenhouse gas, and reduce ocean acidification, because the plant sucks up carbon in the water as food.

“Rob Kinley, the scientist who identified asparagopsis as a methane inhibitor, said it might just be the most promising way to eliminate methane emissions from livestock in the next decade.

“That’s significant because livestock overall account for about 15 percent of global greenhouse gas emissions, with nearly 40 percent of that linked to methane from the digestive process, according to the United Nations’ Food and Agriculture Organization. …

“In a study published in 2016, Kinley and his co-authors found that asparagopsis virtually eliminated methane emissions in lab trials. When a cow eats grass or other fibrous plants, microbes inside its rumen, or first stomach, use carbon and hydrogen from the fermentation of those plants to produce methane, which escapes from the cow mainly through burping, although about 5 percent is released through flatulence.

“Asparagopsis and other types of seaweed have specialized gland cells that make and store bromoform, an organic compound. When the blurry red seaweed is freeze-dried, powdered and sprinkled as a garnish on a cow’s meal, bromoform blocks carbon and hydrogen atoms from forming methane in the stomach.

“In response, the cow makes more propionate, a fatty acid that helps produce glucose in the metabolic process, allowing the animal to more efficiently grow or to produce more milk. That may enable farmers to use less feed and save money. …

“Some evidence suggests that herders in ancient Greece fed their cows seaweed, as did many in 18th century Iceland. The most recent effort began when

Joe Dorgan, a farmer on Prince Edward Island in Canada, observed that his cows that grazed on seaweed that rolled up on beaches had better pregnancy success, produced more milk and suffered less from mastitis than cows that didn’t eat seaweed.

“Before Dorgan could sell the seaweed to other farmers, the Canadian government required proof that it was safe, said Kinley, who was then at Dalhousie University in Nova Scotia and was hired by Dorgan. …

“Dorgan’s seaweed reduced methane by about 18 percent, [but, he says,] ‘The light came on for me that there’s probably a seaweed in the world that’s better than that.’ …

“A number of companies have been working to make asparagopsis taxiformis and asparagopsis armata into commercial products that can be added to animal feed. … While their approaches differ, they share an urgency in getting asparagopsis to farmers, something they recognize is not easy. It’s a challenge to figure out how to grow and process asparagopsis at scale and in a way that will translate into higher earnings for farmers.”

Shahzad Qureshi, founder of Urban Forest, in Karachi, Pakistan.

Today most people have come to realize the importance of trees for everything from reducing global warming to improving life in neighborhoods. The Amazon rain forest (currently in grave danger from Brazil’s government) is known to cool the planet by soaking up carbon in the atmosphere, and urban forests give city residents a chance to cool off — and calm down.

Sometimes it takes a tragedy, but around the world, more people are feeling they better do something themselves to protect trees.

Anna Kusmer reports at PRI’s The World, “Extreme heat often hovers over Karachi, Pakistan’s largest city, creating insufferable conditions for its 16 million inhabitants. But each time Karachi resident Shahzad Qureshi transforms a barren patch of land into a dense, urban forest, he helps his city adapt to extreme urban heat that has become inevitable under climate change. Over the last four years, Qureshi’s organization, Urban Forest, has planted 14 urban forests in parks, schools, people’s yards and outside of a mosque.

“Qureshi’s quest to plant urban forests started in 2015, when temperatures reached over 120 degrees Fahrenheit in Karachi. About 2,000 people in the region died from dehydration and heatstroke. It was devastating.

‘It was just too hot,’ Qureshi said. …’ And one of the things everybody was talking about is that there’s not enough green cover.’

“Around that time, Qureshi saw a TED Talk that changed his life. He listened to a man named Shubhendu Sharma sharing a method to quickly grow dense urban forests. Qureshi was amazed. …

“Qureshi decided to learn Sharma’s technique and bring it to Karachi, joining a growing global community of urban foresters who want to help their cities adapt to extreme urban heat events created by rapid climate change. …

“Sharma’s organization Afforestt has now helped plant 150 mini-forests in 13 countries.

“ ‘So, there is a quite strong global community right now,’ Sharma said. ‘I am very keen on taking this method to every single country of the world.’

“Sharma’s special technique is known as the Miyawaki method. It involves the close placement of a variety of trees with different growing speeds and light requirements to prevent competition for the same resources. The approach specifically uses native species, allowing trees to thrive in their original climates and environments while supporting native bird and insect populations.

“ ‘Most of the city is roads and buildings and built-up urban area,’ said Nadeem Mirbahar, an ecologist with the Swiss International Union for Conservation of Nature Commission (IUCN) on Ecosystem Management, based in Karachi. His organization did a survey and found that only 7% of Karachi had green cover.

“This contributes to an ‘urban heat island’ effect, Mirbahar said. The phenomenon causes cities to be significantly hotter than the surrounding countryside. He thinks Karachi should strive for at least 25% green cover to avoid catastrophic heat events in the future.

“Qureshi’s oldest urban forest is four years old and already has towering, 35-foot-tall Acacia trees full of big, thorny branches and birds’ nests.

“ ‘I have seen bird species in this park, which I have not seen in my life,’ he said. ‘It’s a habitat for them.’ …

“Policymakers in Pakistan have started to look at planting trees as a solution to the urban heat threat, said Umer Akhlaq Malik, a policy analyst at the United Nations Development Program (UNDP) in Pakistan.

“In 2016, the government launched a plan to plant hundreds of millions of trees as part of a project called ‘the Billion Tree Tsunami,’ in response to the fact that the country had fallen to a mere 2% forest cover.

“Malik said … ‘To take it to scale, you need more practitioners who invest their time and energy into this.’

“Malik said the biggest barriers are cost and space. Each forest can cost hundreds of thousands of dollars to establish.

“But Qureshi remains hopeful that the project can scale up. He is working with the UNDP to form a coalition that aims to bring urban forests to every park in the city. He thinks Karachi could look fundamentally different.”

Art: Diana Beltrán Herrera
The artist makes birds and other wildlife from paper and in recent years has started to use her art to support nonprofits fighting for the environment.

Although it is not new for artists to celebrate nature — a compulsion dating at least to prehistoric cave paintings — there’s a new sense of urgency in the era of global warming.

In a 2018 article in the New York Times, for example, 12 artists described how the crisis is influencing their work.

Here artist Xavier Cortada explains to the Times why he made a work showing residential street numbers underwater. “In response to South Florida’s vulnerability to rising sea levels, the village of Pinecrest, Florida will encourage its 6,000 households to install an ‘Underwater HOA [Homeowner Association]’ yard sign (similar to the 18- by 24-inch ‘Home for Sale’ yard signs used by realtors) on their front lawns during the first week of December. I numbered each yard sign from 0 to 17 feet (the municipality’s land elevation range) to show how many feet of melted glacial water must rise before a particular property is underwater.” Oy.

860_climate_change_and_artArt: Xavier Cortada
This painted sign is a marker that someone can plant in their yard showing that the property would be underwater with a sea-level rise of five feet.

Meanwhile, the fascinating website This Is Colossal has for some years been following the amazing paper creations of Diana Beltrán Herrera as she expands from birds she knows to environments she has never seen to helping nonprofits battle climate change.

Grace Ebert writes, “In 2012, Bristol-based artist Diana Beltrán Herrera [began] sculpting impeccably layered paper birds and other wildlife as a way to record her surroundings. Her lifelike pieces continuously have captured nature’s finely detailed and minuscule elements, like the fibrous texture of feathers and the veins running through leaves.

“Today, the artist has expanded the practice to include exotic species and environments she’s never seen up close, developing her paper techniques to express the more nuanced details of the shapes and textures she studies in biology books. Now focusing on the structural elements of fungi, fruit, and florals, Beltrán Herrera shares with Colossal:

‘Paper as a medium for documentation allows me to register and create notions and ideas of subjects that I have not experienced in real life but that I can experience when a sculpture is completed. I like this approach because it is not harmful, and through my work, I can show and tell my viewers about the things I have been learning, of the importance of nature just by researching and making it myself.’

“Much of her work centers on conservation efforts and environmental justice. For example, a recent commission by Greenpeace UK bolstered the organization’s Plastic Free Rivers campaign. ‘I am constantly looking for more subjects that are relevant to the times we are living in, so that through my work I can communicate important information that can educate or just make things more visible.’ …

“Her hope is to merge graphic and digital design with her paper pieces, potentially adding in animation, as well. Ultimately, her goal is to dive into larger projects. ‘I don’t see my work as something I want to know how to make and stay safe, but as a challenge, that will always allow me to wonder how to execute and create things that were never made with paper,’ she says.” More.

Using the constant flow of the Gulf Stream in the Atlantic Ocean to generate power holds promise for an energy future based on renewables.

People fighting global warming have been understandably concerned that coronavirus has soaked up all the oxygen (to coin a phrase) in the public forum. On social media, they try to remind us that health issues — and racial justice, too, for that matter — are inextricably tied to pollution, global warming, and climate justice. I heard one expert opine on the radio that our clearer skies would not last and that as polluting manufacturing slows down so does manufacturing related to renewable energy.

So I was happy to see from today’s story that inventors in the renewable arena are still inventing.

Craig Pittman writes at the Washington Post, “Nasser Alshemaimry was on a boat last month, heading for a spot in the Atlantic Ocean to test out his turbines. He was also, he said, heading for completion of his final life goal.

“ ‘This is my last hurrah,’ said Alshemaimry, 70. ‘I’m going to do this and then retire.’

“A year ago his company, OceanBased Perpetual Energy, agreed to work with Florida Atlantic University to develop a way to generate electricity by harnessing the steady-flowing Gulf Stream, the powerful ocean current that brings warm water from the Gulf of Mexico into the Atlantic and up the East Coast to Canada. Now his company was ready for the first test of five types of turbines to see which one would work best while anchored 80 feet below the ocean’s surface.

“A successful test, Alshemaimry said, would lead to a project that would cost an estimated $16 billion. The goal: in five years, producing 5 gigawatts of electricity from turbines spun by the Gulf Stream, which would be sent through underwater cables to a power distribution station built in the West Palm Beach area.

“The 12-person team submerged the turbines in the Gulf Stream current approximately 20 miles offshore between Broward and Palm Beach counties [and] left them there for 24 hours to see which ones would spin the best in the Gulf Stream’s flow, producing power with the fewest problems. …

“All of the turbines worked well, but the team selected a design that looks like a pair of airplane engines mounted on a single wing to eliminate the torque caused by the rotating propellers.

Ocean energy works very much like wind power — the force of the sea turns the propellers of a turbine, activating a generator to produce electricity.

“Small numbers of underwater energy devices are unlikely to harm marine life, change their habitats or affect the natural flow of ocean waters, according to [oceanographers] with the U.S. Department of Energy’s Pacific Northwest National Laboratory in conjunction with the International Energy Agency. But submerged turbines do come with unique challenges — electrical parts have to be sealed and must resist corrosion, while underwater repairs are disruptive and difficult.

“Producing energy from the ocean is not a new idea. The La Rance tidal power station in Brittany, France, has been using 24 turbines to convert ocean tides into electrical power since 1966. Ocean power produces none of the carbon emissions linked to climate change, and it appeals to some energy executives because tides and currents are predictable, unlike solar and wind. But the cost of building the complex infrastructure required is so great that, so far, solar and wind have outpaced it. …

“ ‘Many of these niche applications, while interesting and helpful for research purposes, can’t compete in the wholesale power market,’ said the [Energy Information Administration’s] Glenn McGrath. …

“Gabriel M. Alsenas, director of the Southeast National Marine Renewable Energy Center at Florida Atlantic, said that’s in part because ocean energy hasn’t been given the same government subsidies [as] solar and wind. …

“Alshemaimry, a Saudi entrepreneur with prior experience building solar-powered homes, spent several years working on a never-completed tidal energy project in Sweden. Then [he] met a U.S. Department of Energy official who suggested he contact Alsenas at Florida Atlantic University about the use of ocean currents. …

“After one phone conversation … Alsenas said, Alshemaimry dropped his Swedish project, switched from waves to currents and moved his entire operation. …

“ ‘Tidal is not 24/7 power,’ [Alshemaimry] said. ‘It’s back and forth. … The Gulf Stream flows 24/7/365.’ ” More here.
