We wind a simple ring of iron with coils; we establish the connections to the generator, and with wonder and delight we note the effects of strange forces which we bring into play, which allow us to transform, to transmit and direct energy at will. Nikola Tesla
I ride my bike for transportation a great deal - occasionally I ride it for fun. But I also have a generator bike that's hooked up to my solar battery pack, so if I ride 15 minutes hard on my bike, that's enough energy to toast toast, or power my computer. Ed Begley, Jr.
