A bicycle-powered welder
Sounds like gyms should get in on the act, and hook their exercise equipment up to power something else.
Bicycle Design: A bicycle-powered welder
Mike and the group made an inertia friction welder powered by a bicycle. You can check out their entry video right here. The video shows the pedal powered machine in action as it welds 2 pieces of aluminum together. The resulting weld joint may not be the prettiest I have ever seen, but it is really exciting to see the machine working right before your eyes.
