Bicycle powered home appliances could provide the ultimate 2-in-1 solution for many people (ie. get some exercise while doing your chores). A great example of this is a bicycle-powered washing machine created by a fellow who goes by the name Homeless Dave. The spin cycle is powered by bicycle, as is a TV for entertainment during the “spin”. As for the dryer…well, I suggest a clothesline.Via Treehugger.
