SPINNING/CYCLING: Charge your car while exercising
My idea is a dynamo integrated with the charging system via a gym for spinning/cycling; the person exercising can charge his car.
Description
The idea is to convert mechanical energy to electricity by utilizing our fat stores via exercise specifically through cycling/spinning which can be integrated with a dynamo for electrical power generation. A win win scenario since as we improve our health fitness and endurance we can also charge our cars.
