The Solar Dog prototype charger from Erik Schiegg is a solar panel attached to a dog sweater. I’m not sure how efficient it is, but I could see this being handy. [via recombu]

My Android phone is charged in no time… The dog feels good and I’m feeling good and planet mud is turned a little bit more into planet earth. But this idea would be interesting for farmers around the world, letting their animals collect electricity, too.
