Hello. For a school project, my group is making a rolling cart that uses power it generates from motors attached to the wheels to charge a cell phone. I was wondering if anybody could help by suggesting a way that I could store the charge from the rolling wheels so that, even when the cart is not rolling, the phone continues to charge. Is there a way I could do this without greatly increasing the resistance on the wheels but still generate a descent amount of power?
thanks!
thanks!
