I am aware that only small amounts of power are generated, on one site i looked at for some infor it said that after 2 mins of shaking (shake torch) the capacitor had 1v, not much power for sure, but imagine the cumulative power generated, just from walking..
Lets say for arguments sake i have a capaciter that has 1v of charge, how would i go about putting that charge into a 3.7v battery?? all the Li polymer battery chargers i can find require a higher input voltage than the battery itself, i.e 5v,
So does this mean i could do something as simple as use a dc-dc converter on the capaciter to provide me with a 5v supply to the battery??
This may not be very efficient so im thinking there might be a better/simpler way
