Using photosynthesis to power hydrogen production
Researchers have found that if they insert platinum nanoclusters into the photosynthetic machinery of bacteria, one acre could produce an amount of hydrogen equivalent to 79 gallons of gas per day. [more inside]

For the second time in two years a team from Germany has won the US Department of Energy's Solar Decathalon. This year's entry was a cube shaped house entirely covered in 300W and 70W solar panels generating a peak of 11.1kW. The DoE has published a complete product directory of all the subsystems and components used to build each house. Another notable design is the Canadian Team North house designed for optimal solar+insulation performance in high latitude climates.

Peak Oil, 1925. In 2000, 20% of new buildings will be solar equipped. By the late 1990s, 90% of the world's energy will be nuclear-generated. These and other erroneous projections are being collected as part of the Forecast Project on the website Inventing Green: The Lost History of Alternative Energy in America.

Could giant magnetically levitated windmills be the solution to the worlds energy problems? Chinese scientist have reported 20 percent increase in capacity over traditional wind turbines using maglev turbines, and now Arizona-based based Maglev Wind Turbine Technologies claims their turbines will have 1000 times the capacity of a traditional turbine. Not everybody is convinced.

Katrinanomore&global warming Welcome to the first web site in America dedicated exclusively to raising awareness about the connection between hurricane Katrina and global warming. See below an essay just written by author Mike Tidwell that explains how climate change will soon turn every coastal city in America into another New Orleans unless we make a rapid switch to clean, renewable energy worldwide.

Cool! Toronto's Deep Lake Water Cooling System was launched today. The system cuts electricity consumption in commercial buildings by 75 per cent by drawing near-freezing water through pipes extending five kilometres out into Lake Ontario. According to the city, the system will save enough power to service more than 100 Toronto office towers or 4,200 homes per year, and it will eliminate 40,000 tonnes of carbon dioxide. Here's a public television segment explaining the process. Seems like it makes a nice complement to the lakeshore windmill.

Burn peanut butter not fossil fuels. Great little piece on a new cell phone charger that you windup to recharge and the promise of a windup charger any application. I always thought the windup flashlights were great but the windup radios with one speaker leave a lot to be desired.
