Hello. I am trying to build an impulse driven motor to heat a small heating element. The problem is that this motor/ generator needs to be about as small as a wallet. What I to work with to create energy is about 150 pounds of pressure ever second or so for a duration of about .2 seconds. There seems to be plenty of designs on how to create power from a high velocity motion, but i couldn't find anything on slow strong movements. I found some useful information in the toymill section, and the gear system from kidwind.org seems to have some merit, however that is about 4 times too large for the project. Is there any way to turn this force into emf? I'd really appreciate some help. Thanks
PS ... perhaps using a small electric motor to charge a capacitor which dispersed heat periodically? however I still need a way to efficiently spin a small electric motor like that.
