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.

A very small footprint indeed

Whilst on the subject of summer and feet and the covering thereof, Mrs Green today continues the theme and segues into a story about a remarkably small motor-home/camping carbon footprint. Via Treehugger, who also wrote about an 80 cm x 120 cm box that hides furnishings enough for an entire room, we are introduced to a portable modular living system that fits into a car.

By sliding the box-shaped units over each other, holiday makers can access a sink, hob, dining table, picnic table and chairs, a shower, and a double bed. Oh – a hot water boiler too.

Mrs Green learned, amongst other things, at that  “Once connected, electrical devices such as the pump and water boiler, as well as optional add-ons such as the fridge, and iPod and computer chargers, will all power themselves off the car battery, which will cut out once the battery only has 11 volts remaining — the minimum required for starting an engine. The battery will then recharge as the car is driven.”

Camping, anyone?

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.

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?
