We have seen power devices that use a crank, wind, and sun, but pedal power is new to me. Power up your electronic gadgets while burning some chub off of your butt. The Japanese Rakuten charger is powered by pedal energy. Use your feet or your hands to crank out electric power. The unit has its own batteries for storage… and can charge your other gadgets off of an outlet port. You have to admit, it would feel good knowing that your iPod was powered by your hard work.
