Once in a while I like to look at inventions and innovations of common people, yours, the guy next to you, the old lady living across the street, my nerdy officemate, you know, those folks you do stuff at home that are really marvelous. This is one from Homeless Dave which I found at GreenOptions. I think a do-it-yourself, self-propelled, power washer is just what you need to lose two things -- high electricity bills and excess calories and gain one - clean, environment friendly clothes.

Great for students I think. Lots of excessive energy there and a heap of dirty clothes!
