Solar Technology Powers Poor Schools

Posted in Uncategorized, tagged , , , , , , , , , , , , , , on January 18, 2013| Leave a Comment »

Global Envision is part of an effort at the nonprofit Mercy Corps “to foster a richer conversation about global poverty.”

Last fall, Global Envision’s Erin Butler set off to investigate technologies that help schools in impoverished parts of of the world.

“For some students, hopping on the school bus is hopping into the classroom. Four communities are using solar-powered mobile classrooms to overcome inaccessibility to the power grid.

“Last week,” writes Butler, “we looked at a bus in Chitradurga, India, that brought modern computer technology to students in energy-poor rural schools through solar power. SELCO, a private energy company, engineered the bus with 400 watts of solar modules, 10 laptops, fans, and lights.

“Circumventing the area’s erratic power supply with its solar panels, this bus provides much-needed modern computer education and exposure to the advantages of solar energy. Motoring through rural villages in Chitradurga since January 2012, the bus has reached ’60 schools and 2,081 children,’ the New Indian Express reported in early September. …

“Where there’s more water than land, boats replace buses, and with rising sea levels, low-income Bangladeshi students have difficulty getting to school altogether.

“Pushed to inaccessible riverside settlements that lack basic infrastructure, students often can’t get to school due to monsoon flooding. Shidhulai Swanirvar Sangstha, a nonprofit organization started by Mohammed Rezwan, rides the rising tides with his solar-powered floating schools.

“Trained as an architect and personally experienced with soggy school disruptions in Bangladesh, Rezwan rode a brainwave that led him to floating schools. Combining the best of traditional boat design and modern sustainable practices, the organization’s 54 boats have been operating since 2002 and have served over 90,000 families.”

Entrepreneurs’ 1-Minute Pitches

Fun time at Mass Challenge!​

Mass Challenge is an incubator “accelerator” for entrepreneurial companies, perhaps the biggest worldwide. I’ve blogged about it before.

Of the 125 finalists in this year’s challenge, 48 gave one-minute pitches last night to an audience of about 200 friends, family, and investors at 1 Marina Park on the Boston waterfront.

Besides being entertaining, it was inspiring. So many people working hard on so many great ideas!

A couple noteworthy presentations were from MIT people. Helmet_Hub tapped the skills of MIT materials science students to create a helmet-vending machine. They have already partnered with the City of Boston’s Hubway, which lends bikes point to point. Another MIT-based organization, Global Research Innovation & Technology (GRIT), uses bicycle parts to make inexpensive wheelchairs for Third World patients. Very impressive. (More on GRIT here.)

I also wrote down that soundfest has a better kind of hearing aid. Prime Student Loan screens students so banks can make a safe loan even if graduates have no FICO score.

Wanderu was one of the few female-run companies. It does for ground travel what kayak and others do for air. Zoomtilt creates ads that are said to be so funny and entertaining, people actually want to watch them. Guided Surgery Solutions helps oral surgeons drill into the right place.

Roameo helps you find out what’s going on near where you are right now. Newartlove helps artists sell their work. Social Made Simple helps small businesses with social networking. (Check it out, Luna & Stella.) CellanyxDiagnostics has a more precise test for prostate cancer than the PSA.

I will likely follow up on a worthy-cause business called Bootstrap Compost. They teach you to compost, give you the bucket, pick it up, deliver it to farms, and give leftover compost to schools. You can have some, too. Bootstrap is very low-tech, doing most travel on bikes. It is proud of keeping tons of food scraps out of landfills.

I was also impressed at the Mass Challenge diversity — men, women (OK, not many women), old, young, scientists, artists, business types, different races, different nationalities, humorous, solemn.

No need to worry about the economy long term. Not with the joy of invention alive and well.

Tiny Tweaks, Huge Impact

Posted in Uncategorized, tagged , , , , , , , , , , , , , , , , , , , , on October 5, 2011| 2 Comments »

Some years ago, the John Adams family biographer Paul Nagel introduced me to physician/poet Norbert Hirschhorn. Paul told me that Bert was on the team that helped save thousands of lives in Third World countries simply by distributing water to which sugar and electrolytes had been added. (A National Institutes of Health paper references Bert’s 1973 research on “oral glucose electrolyte solution for all children with acute gastroenteritis” here.)

A special NY Times science supplement on Sept. 27, 2011, “Small Fixes,” reminded me of Bert and the notion that small innovations can have a huge impact.

Among the great stories in the supplement. is this one about Thailand’s success fighting cervical cancer with vinegar.

It turns out that precancerous spots on the cervix turn white when brushed with vinegar. “They can then be immediately frozen off with a metal probe cooled by a tank of carbon dioxide, available from any Coca-Cola bottling plant.” The complete procedure, which can be handled by a nurse in one visit, has been used widely in Thailand, where there are a lot of nurses in rural areas.

In Brighton, Massachusetts, Harvard’s George Whitesides founded Diagnositcs for All to commercialize his inventions, including a tiny piece of paper that substitutes for a traditional blood test for liver damage. Costing less than a penny, “it requires a single drop of blood, takes 15 minutes and can be read by an untrained eye: If a round spot the size of a sesame seed on the paper changes to pink from purple, the patient is probably in danger.” Read the Times article.

Amy Smith at MIT is another one who thinks big by thinking small. Read about her Charcoal Project, which saves trees in poor countries by using vegetable waste to make briquettes for fuel.
