"A practical [inexpensive] artificial leaf has been one of the Holy Grails of science for decades. We believe we [Sun Catalytix] have done it." Video: Professor Daniel Nocera at MIT
The world's largest solar power plant will probably be cleared for construction in California. At 1GW it is the size of a nuclear power plant and nearly doubles the US installed base of commercial-scale solar power. It will take 6-years, $6-billion and 7,000-acres. Proposed site (on Google maps). It will use parabolic trough's (video). It is being built by a German company (construction video / operation animation). There are many other CSP (Concentrated Solar Power) projects.
How Africa's desert sun can bring Europe power. A £5bn solar power demonstration project called Desertec is being developed by Trans-Mediterranean Renewable Energy Cooperation (TREC) that would send solar energy northward from African deserts. The goal is in 30 years to provide a significant fraction of Europe's electricity needs.
Popular Science has named Nanosolar the #1 innovative product of the year. Finally, cheap and ubiquitous solar power has arrived, “You’re talking about printing rolls of the stuff—printing it on the roofs of 18-wheeler trailers, printing it on garages, printing it wherever you want it,” The only problem is demand, so they're building the world’s largest solar-panel manufacturing facility in San Jose. See 96 other innovations in PopSci's Best of 2007.
The Zephyr, a solar powered plane, has smashed the record for the longest duration un-manned flight, staying aloft with engines running for 54 hours. This was just a test run at the US military White Sands Missile Range in New Mexico, according to the UK developers, "You ain't seen nothing yet". Meanwhile in Switzerland, development continues on the Solar Impulse, which has a goal of flying around the world, manned(!), by 2010.
Solar Tower (text and video). "The rays of sunlight reflected by a field of 600 huge mirrors are so intense they illuminate the water vapour and dust hanging in the air."
Cheap solar power poised to undercut oil and gas. The "tipping point" will arrive when the capital cost of solar power falls below $1 per watt, roughly the cost of carbon power.
CitizenRe is a solar power rental company for the home. Free to install (!), a monthly rental fee is equal to what would normally be paid to the power company. Video.
The 16th annual Tour de Sol showcases experimental vehicles built by students, individuals, and corporations that can cut greenhouse emissions, and compete for top awards. More photos and reports. Then cruise on over to the Green Car Club for a list of Green Cars available to buy today.
