Can you use an alternator on an axle to recharge batteries? Answered
If you have a battery powered vehicle of some sort, can you put an alternator/generator or something on the axles to generate electricity to recharge the batteries the vehicle runs on? When the axle turns, the brushes pass over the coil generating electricity which is then routed back to the batteries thereby recharging the batteries. Please pardon the bad Paint drawing, but something like this.
