Wind Power For Campers

I recently made a post on this blog about inflatable wind turbines. Trudy commented that it would be nice if there was a smaller version for campers. Orange clearly thought the same thing and commisioned a prototype tent mounted wind generator. The resulting device charges up a battery which in turn can charge up another device. Here's a picture: -

• The good news is that it only weighs 150 grammes.
• The bad news is that to generate enough energy to fully charge a mobile requires 24 hours of 12mph wind (I guess it won't run a cool box).

Still it is only a prototype and may improve. Find out more here and here.
