    Hello Everyone,

    Im trying to propose a project that will increase the battery life of a battery powered Remote Controlled Car (RC Car) using dynamic charging. The project has two capacitors linked to two batteries. As one battery is being used, the other battery is being charged by one of the capacitors.

    The capacitors will receive charge through electromagnetism from magnets and coils attached inside of the wheels of the RC Car. Battery-A will be used to power the wheels. While the wheels are spinning the coils begin to produce an electrical charge. The charge will be stored on Capacitor-A. When Capacitor-A reaches a desired voltage, charge will be directed to Capacitor-B. Once Battery-A reaches a low voltage, the HCS12 will switch main power to Battery-B and Capacitor-A then charges Battery-A. Once Capacitor-A is discharged, Battery-A is then used as main power. The wheels then charge Capacitor-A and Capacitor-B charges Battery-B. Then the cycle repeats.

    I know there are a few details missing, but I just want to know if its possible first.
    what do you think? possible? Ideas?

    In essence, this is a perpetual motion machine. Due to less-than-perfect efficiency, you will lose significant power trying to drive the car and capture power from the wheels. The net effect will be to make it harder for the battery in use to move the car a given distance, and the charging battery will not recapture a significant fraction of the energy expended at the changeover. If you want significantly more run time, place battery A & B in parallel.

    capture energy only under braking conditions. perhaps in a RC model car this (what i propose) is really not feasible since RC cars technically dont brake. you could perhaps capture motion energy (KE) from the wheels only when power is not being applied to the motor. better yet, build a special motor that serves two functions. 1) does work when power is applied, 2) acts like a alternator when power is not applied......
