Gmoke sez, "Richard Komp has taught people how to make solar as a cottage industry in at least 16 different countries over the last few years. There's a documentary called "Burning in the Sun" about his work in Mali and he's even got an Introduction to Photovoltaics series on YouTube. Reports from his 25 international trips available here"
Gmoke sez, "Two years ago, two Bedouin women, Rafea Al Raja and her aunt Seiha Al Raja (Um Bader), returned from a six-month solar engineering training at the Barefoot College in India as 'solar engineers' to start a training center for other women. Although they solarized 80 houses in their village, the government of Jordan, NGOs and international organizations have shown little or no interest in their work. Even with a documentary on their training and projects at home, 'Solar Mamas', there hasn't been enough funding to sustain their work and their dreams.
“We are still not working and the training has not started either,” Rafea told The Jordan Times in an interview on Saturday.
They came with hope, she said, but this hope is fading away. The government, NGOs and international organisations are showing little or no interest, according to FES officials, leaving the project stranded in the desert.
“Now even our fellow villagers have started to make fun of us because they see nothing is happening on the ground,” said Rafea, who with her aunt were received with festive firing and an “official” ceremony upon their arrival from India.
The situation took a dramatic turn for both Rafea and Um Bader. Although they provided solar energy to 80 houses in the village, they are now facing the darkness of personal problems that have plighted them since they completed their training in India.

A worthy and overlooked story in the NYT by Elizabeth Rosenthal about a new economic riptide hitting Central America, a result of America's changing corn policy. The US is now using 40% of our own corn crop to produce biofuel, and tortilla prices have doubled in Guatemala, which now imports about half of its corn.
"Recent laws in the United States and Europe that mandate the increasing use of biofuel in cars have had far-flung ripple effects, economists say, as land once devoted to growing food for humans is now sometimes more profitably used for churning out vehicle fuel."
This is the difference between low kinetic energy (top) and high kinetic energy (bottom), as illustrated in the 1956 Disney book Our Friend the Atom. It may be useful in visualizing some of the ideas presented in my recent feature on space radiation.

General Electric has moved some of its key appliance-manufacturing work back to the USA, re-opening "Appliance Park," a megafactory in Louisville, KY. The company is finding it cheaper to do some manufacturing in the US relative to China, thanks to spiking oil costs, plummeting natural gas prices in the US, rising Chinese wages, falling US wages, and, most of all, the efficiencies that arise from locating workers next to managers and designers.
The GeoSpring suffered from an advanced-technology version of “IKEA Syndrome.” It was so hard to assemble that no one in the big room wanted to make it. Instead they redesigned it. The team eliminated 1 out of every 5 parts. It cut the cost of the materials by 25 percent. It eliminated the tangle of tubing that couldn’t be easily welded. By considering the workers who would have to put the water heater together—in fact, by having those workers right at the table, looking at the design as it was drawn—the team cut the work hours necessary to assemble the water heater from 10 hours in China to two hours in Louisville.
In the end, says Nolan, not one part was the same.
So a funny thing happened to the GeoSpring on the way from the cheap Chinese factory to the expensive Kentucky factory: The material cost went down. The labor required to make it went down. The quality went up. Even the energy efficiency went up.
GE wasn’t just able to hold the retail sticker to the “China price.” It beat that price by nearly 20 percent. The China-made GeoSpring retailed for $1,599. The Louisville-made GeoSpring retails for $1,299.
Everybody poops, including panda bears. (See about 0:35 in the above video for evidence.) But panda poop could turn out to be quite a bit more important than your average animal excrement. That's because scientists are "mining" it for bacteria that could help make better biofuel.
The key problem with biofuel today is that the stuff that's actually economical to produce — i.e., corn ethanol — isn't really that great for the environment. Corn farming uses a lot of fertilizer, water, and herbicide. Using corn that was previously grown for food to make fuel, instead, can lead to deforestation as people clear land to make up for the lost food farming. Some models of carbon dioxide emissions suggest that, by the time you factor in things like fossil-fuel derived fertilizers and the deforestation, a gallon of corn ethanol might not be any better for climate change than a gallon of gasoline. Not all the models agree on that. But even if corn ethanol produces fewer carbon emissions than gas, you still have to deal with the fact that growing nutrient-hungry corn on the same patch of ground over and over and over is really bad for local soil and water quality.
Cellulosic ethanol could be a much better alternative — particularly cellulosic ethanol made from native, perennial plants that don't require heavy inputs to thrive and actually improve the health of the land they're grown on. The problem: Converting those plants into fuel is, so far, a lot more expensive. Cellulose — the plant fiber that makes up things like stalks of bamboo and tall prairie grasses — is tough stuff and hard to break down.
That's where panda poop comes in. Pandas process tons of cellulose every day, right in their guts. Maybe the bacteria that work for them could work for us, too.
Yoko Ono and Sean Ono Lennon launched "Artists Against Fracking" earlier this year, and have received no response from NY gov. Andrew Cuomo to their request to meet and talk about the idea of a ban of fracking in New York. Now, Ono and Lennon have launched a billboard campaign on a route where the governor often passes. “Governor Cuomo: Imagine there’s no fracking,” the sign reads.
Energy emergency: Sandy profiteers sell gas, generators at predatory prices on post-apocalypse Craigslist
New Jersey governor Chris Christie signed an executive order announcing a state of energy emergency and instituting gas rationing for the purchase of fuel by motorists in 12 counties, starting today at noon.
Make way for price-gouging entrepreneurs!
Try this, to get a taste of how bad it is: search for "gasoline," "gas," or "generator" on NY Craigslist right now. Gas sales I've found on Craigslist range from $5 to $20 a gallon, but there are probably ads at higher prices. My favorite was the 55-gallon drum of gas for a thousand bucks. Unleaded! Cash only, folks.
Not only is this exploitative, it's explosive. A black market of gasoline reselling, without appropriate safety measures, seems to me like a recipe for tragedy.
BURN: An Energy Journal, the radio documentary series hosted by former NPR journalist Alex Chadwick, has a 2-hour election special out. It's the most powerful piece of radio journalism I've listened to since—well, since the last episode they put out. You really must do yourself a favor and set aside some time this weekend to listen to “The Power of One.”
Energy policy, defining how we use energy to power our economy and our lives, is among the most pressing issues for the next four years. In this special two-hour edition of BURN, stories about the power of one: how, in this election season, a single person, place, policy or idea can — with a boost from science — affect the nation’s search for greater energy independence.
The documentary examines how "individuals, new scientific ideas, grassroots initiatives and potentially game-changing inventions are informing the energy debate in this Presidential Election year, and redefining America’s quest for greater energy independence." It was completed and hit the air before Hurricane Sandy, but the energy issues illuminated by that disaster (blackouts, gas shortage, grid failure, backup power failure at hospitals) further underscore the urgency.
The plant's operator, Exelon, says there is no threat to public safety, or the structural integrity of the plant.
Those pumps are not essential since the reactor has been shut for planned refuelling since Oct. 22. However, a further rise to 7 feet could submerge the service water pump motor that is used to cool the water in the spent fuel pool, potentially forcing it to use emergency water supplies from the in-house fire suppression system to keep the rods from overheating.
On Tuesday, an NRC spokesman said the levels reached a peak of 7.4 feet -- apparently above the threshold. As of 6:10 a.m. EDT waters were at 6.5 feet, with the next high tide at 11:45 a.m. He said the company had moved a portable pump to the water intake structure as a precaution, but has not needed to use it.
America lost a great Maker last week. Stanford R. Ovshinsky was a self-taught engineer and inventor who held more than 400 patents when he died on October 17th at the age of 90. The name may not be familiar to you, but his work is. Ovshinsky is credited with inventing key technologies behind flat-panel liquid crystal displays that we use to watch TV, work on the Internet, or play with our phones.
He was also the inventor of the nickel-metal hydride battery — a rechargeable battery that now powers everything from laptops to the Prius. Ovshinsky (along with his wife, Iris, who held a Ph.D. in biochemistry and was his research partner for much of his life), began working on improved versions of batteries, solar cells, and other energy technologies beginning in the early 1960s. More than a decade before climate change became a well-established fact, Ovshinsky was concerned about the pollution and political instability that went along with fossil fuels. He spent the rest of his life developing better alternatives.
For a good introduction to how truly groundbreaking Ovshinsky's ideas were, check out a 1978 article from Popular Science, all about his invention of amorphous silicon semiconductors — a technology that today forms the basis behind both thin-film solar panels and smart phone displays. At the time though, it made Ovshinky a controversial figure.
