We need more alternative energy sources. Surely the best answer is to power everything with a bunch of little critters running on wheels in their cages! Simply carry the little buggers in one's pocketbook with the appliances hooked up to the wheels in motion. Perhaps some creative 'Catter could patent lots of things powered in the manner of the Flinstones. Perhaps fellow 'Catters could get somewhat of a discount off the price of, say, a chipmunk powered chromatic tuner.
