A Solar Grand Plan: By 2050 solar power could end U.S. dependence on foreign oil and slash greenhouse gas emissions. [Via Gristmill.] [more inside]
The Thirteen Towers of Chankillo in Peru may be the Western Hemisphere's oldest known full-service solar observatory, showing evidence of early, sophisticated Sun cults, according to archaeoastronomy professor Clive Ruggles. The 2,300-year-old complex featured 13 towers running north to south along a ridge and spread across 980 feet to form a toothed horizon that spans the solar arc. Last year, another ancient observatory was discovered in Peru by Robert Benfer. The Temple of the Fox is 4,200 years old, making it 1,900 years older than the Chankillo site, but wasn't a complete calendar.
The kilometer-high Solar Tower to be built in Australian outback (previous post) has finally purchased a site, and construction may be finished in 2009. Other towers may be built in China and the US.
Barefoot Solar Engineers. India's Barefoot College teaches poor and illiterate women to build and maintain rural solar systems in areas with little or no electric supply. [Via WorldChanging.]
A kilometre-high solar tower, to be built in the Australian outback by EnviroMission Ltd, will become the world's tallest structure when completed in 2006. Designed by Jorg Schlaich of Schlaich Bergermann und Partner, the solar tower (or solar chimney) operates like a hydroelectric power plant, but uses hot air instead of water, and it could provide enough electricity for 200,000 homes. Time calls it one of the best inventions of 2002, and I think it's one of the most ingenious ideas I've ever heard. Another solar chimney project was planned in Rajasthan, India, but I haven't found any information on its current status.
