I've been thinking about how Tesla could improve the range the cars on a singular charge for those who drive long distances but want to save on gas. What i would like to know is, normal gasoline cars use alternators to charge their batteries while they are driving, so why couldn't Tesla cars use a similar form of this? Where an electric generator is spun via the axles of the car moving. I am by no means an electrician or know how this could be an issue for the batteries, but my thought is. If you have four small electric generators near each wheel, while the car is moving a belt (like on an alternator for gas cars) would rotate it, producing electric charge. This in turn could be fed into a backup battery for the car or into the main one (depending on the model and issues with that) Like I said i am by no means an electrician but its just something I could see working to increase the range of a singular charge from Tesla's batteries.
