My idea is to assemble in a normal car, a generator (turbine) to produce energy to recharge the Ion-lithium batteries, and generators to use the rotation of the wheels and axles to produce more energy, and install solar (light) pannels on the bonnet and trunk of the car. This vehicle would not need to charge from main sockets or need to refuel. How can it be done?
 
A very noble ideal but completely impossible. Your first idea is to install a generator to charge the batteries, have you thought how you will power the generator? Generators need fuel to produce electricity which has to be replaced.

The main things you have to overcome are frictional losses in bearings and wheels and drag due to air. Once you've overcome these problems you can start thinking about perpetual motion.
 
Well, an alternator in a car keeps the battery charged, so with maybe compact generators driven from each wheel, plus a turbine and solar panels, I'd say you have a pretty good idea. If you're planning on building on, try it on something like an R/C car first, and proceed from there.

If I'm not mistaken, there have been cars built that run solely on solar power, so having that during the day while the generators charge up another back-up batter for night driving, it should be possible. This is assuming that the car would be intended to be driven for a constant 24 hrs.

And you don't have to worry much about the sky clouding up; last I check, it's brighter outside on a cloudy day than it is in an office, yet solar powered calculators work indoors. So, the clouds wouldn't stop a solar panel from working.

Now, combining these ideas with comfort..well, that's another story....
 
conservation of energy means you only get out what you put in.

You cannnot get energy out enough to charge it to make it move - that is perpetual energy and is logically impossible.

The only thing you can do is run it off solar power, but then it would stop on a cloudy day or night so impractical for use.
 
It can't.

The best you can do is use a regenerative braking system (where braking takes energy and recharges the battery).

You cannot have a perpetual motion system, and solar panels would not provide enough energy to drive the car even with regenerative braking.
