A portable solar generator in a briefcase

Thousand Suns has produced a portable solar generator packaged in a flight-case.Portable Solar Generator

Unclip, fold out and position the solar panel using the fold-out legs and it will charge fully in six hours. The unit can also  be charged using a mains charger in about four hours.

EnviroGadget has plenty more information and pictures of this sleek 4.1 kg solution to powering phones and fridges among other things. Mrs Green is also happy to read that the battery is 95% recyclable and has a life of about 10 years.

Building a sun-tracking solar cooker

sun tracking solar cookerNot for the faint-of-heart DIY-er, but perfectly possible for those of us blessed with more experience – TreeHugger has a look at the who and the how of doing this.

To quote: “[Instructable user Keith] created an insulated box (including two panels for mirrors, and removable back doors), mounted it to allow it to tilt and rotate (plopping it on a big Lazy Susan dealt with the rotation part), added a motor so it could move itself, and of course devised a simple but great solar panel system so that the unit could detect and track the sun.”

The page has a fine video of the cooker too, and more detail and instructions can be found on the Instructables site.

Solar-power from windows?

solar-power-from-windowsThe U.S. Department of Energy’s Los Alamos National Laboratory and Brookhaven National Laboratory have developed a transparent film that could potentially generate power by transforming windows into solar panels.

Imagine every window of your house generating power. Now – imagine every window of every office building and skyscraper doing the same.

The Green Tech Gazette has an article about it here, and the Los Alamos National Laboratory website has more information here.

2010 Solar-car race in South Africa is over.

solar-powered-carLast week, on Sunday, the 4 000km 10 day Solar Challenge Race ended in Pretoria. IOL News describes it as one of the world’s toughest alternative energy races. There were 5 cars driven by solar, hydrogen or electric power. Japan’s  car won with  a new record for the event when it travelled 4 061 km purely on solar energy and a South African team set a local record too.

Find more information and pictures of the rather strange looking cars here, and the official home page of the race is here.  Mrs Green thinks the silvery-white one is rather fine.

Solar-powered car ventilator

solar-car-ventilatorI’d like to have one of these.  It fits any car window. The past week has been more than hot. Apparently the solar panel, which is 5 inches by 4.5 inches, powers the fan, which exchanges hot air inside the car for the presumably cooler air outside. If you park in the shade and want to use the fan, there’s a plug-in adapter for the car. Cool!

Unfortunately Mrs Green cannot find anywhere to obtain this little lovely. Local Entrepreneur somewhere?
