Why does this concept not work for an ever-charging battery in a car? You have 4 tires spinning, which creates the same rotational force continuously while a vehicle is in motion. Why does this spinning action of the wheels, not recharge the battery similar to a wind turbine?
Hope that makes sense, but that concept has always confused me. Why would we need recharging stations? If the spinning action of the wheels recharged the batteries during motion? So technically, shouldn't the battery only need an initial charge off the manufacturing line?
