Markus Kayser has designed and built The Solar Sinter, a solar powered 3D printer which creates glass objects out sand. Needless to say, the ability to create objects out of sand using solar power will be welcome in deserts. He took his machine into the Sahara desert to test it. Previously in the Sahara Kayser tested a similiar machine, The Sun Cutter, which uses a ball lens to create a kind of laser cutter.
"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
Solard Death Ray: Power of 5000 suns! [SLYT] The R5800: made from an ordinary fiberglass satellite dish, it is covered in about 5800 3/8" (~1cm) mirror tiles. When properly aligned, it can generate a spot the size of a dime with an intensity of 5000 suns! This amount of power is more than enough to melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant. It stands at 5'9" and is 42" across.
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.
Aurore, a renewable energy (RE) service provider in South India has been designing and developing RE products like solar lanterns and street lights, arranging for microfinance to support installation in remote villages and winning prestigious awards for their work. Cleaner, safer and cheaper than fossil fuels, their business philosophy is grounded in a greater vision than mere profit.
The Solar Decathlon 2005 winners announced. The Solar Decathlon brings together 18 teams of college and university students from around the globe to participate in an unparalleled solar competition to design, build, and operate the most attractive and energy-efficient solar-powered home.
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.
