I know, I switch projects a lot. I just can't stay focused on one thing for too long.Anyway, here's my idea:There's a local museum called Fort Discovery, which, by the way, is quite cool. But, there is this exercise bike they have there, and connected some how (I haven't been there in a while) is a few different home tools, like an incandescent light bulb, a drill, a hair dryer, and something else. There are switches, so you can turn whichever ones you want on, to see what you can power. The "exhibit", if you will, is to show how work = power. Now, I'd like to try to hook something like this up, except a few things will be changed:It would be a regular, moving bike.There would only be a light bulb.I want the power to be stored in a capacitor, because what would be the purpose of having a light while riding in the daytime?Now, besides from the point of me not knowing at all how to hook this up, I wonder if there would be a capacitor that would store enough power to light the bulb for a reasonable amount of time, if say, I used a 60 watt bulb. Then of course, I have a few questions, some of which I may of already said:How big would the capacitor have to be hold enough power to light the bulb up?How many hours (or minutes, if applicable) of moderate riding would it take to store enough power to light the bulb enough to see for about 15 minutes?Would the power stay in the capacitor so that I could charge the bulb a bit over the course of a few days?How would I hook such a circuit up?Could I hook the circuit up so that the power is stored from the wheel going around, rather than my pedaling?Thanks for any and all help, and if this turns out all right, then I may just put an Instructable up. I guess I'll have to see. Thanks again!
