You can ride a stationary bike that is connected to a generator. You supply mechanical energy to an electromagnet that then causes current to flow. On a similar principal, I think I once read an article about a device that you wear on your thighs while you walk or jog, and it recharges the batteries in your walkman.
On Gilligan's Island, the professor once recharged batteries by having everybody stir a solution in coconut shells. That's not terribly far off, really; you can use the heat of a chemical reaction to provide energy to an electrical device.

use the wind or the water in a river to turn a generator then wired to a voltage regulator and to a 12 volt battery,all this from out of a car

There are several methods to generate electricity by yourself but the efficiency is very small and you will end up bankrupt.

Chemical reactions (i.e. electrical cells), a conductor moving with respect to a magnetic field (i.e. a generator), or mechanically moving charges so that they accumulate (i.e. a 'van de Graff generator').
Any of these can be demonstrated in your garage.
