can’t electric cars be self charging by having a wind turbine emblem on the hood and solar cell material roof?
Not really. Putting a wind turbine on the car just increases the drag and makes it less aerodynamic. Putting solar panels on the roof helps a little, but they’re not efficient enough to provide much charge. For example, Toyota has optional solar panels on the 2010 Prius, but they’re just used to power the air conditioning and other systems that require little power. They don’t provide enough power to charge the car.
The wind turbine emblem would create such a tiny amount of energy that it doesn’t matter.
Solar cells on the roof can help cut the amount of energy you need to provide from home, but even a sunny day can’t give your car all the energy it needs. Many websites sell kits that let you install solar cell roofs onto your car.

Don’t forget about the wheels on your car that creates a lot of friction and heat it should be absorbed back creating and saving electricity and the engine gets hot you should collect the engine’s heat and bring it back so that you can create a perpetual heat machine!

The wind turbine creates drag, requiring the vehicle motor to consume more electricity. By laws of energy conservation this drag is equal to or greater than the amount of electricity such a turbine would produce.
Solar cell roof does not yield enough power to run a car.

they do have a car with a solar roof… looks like an ashton martin but different brand’s concept. they also have invented shock absorbers that use the energy from bumps. power producing spinners would be a pretty got idea, but propellats on a vesicle would not be able to operate at that high of speed without burning up motors from soooo much friction

If you look at wind turbines and see how big they are you might realize that a little one could only add a small amount of power when the car is sitting stationary in a good stiff breeze. When the car is moving the turbine will increase the drag on the car and take energy away from the vehicle.
Insolation is the energy received from the sun. There are several things that affect insolation levels. Time of day is important. No solar energy will be received at night and most will be around noon. The angle to the sun is important. This is why most stationary solar panels are tilted at an angle based upon the latitude. This is also why solar electric panels lying relatively flat on the roof of a car will be less effective than a stationary array.
So while these things may have benefits to a stationary vehicle on a mobile one they are much less efficient. The same money would be more efficiently spent on stationary energy collectors.

It takes energy to create energy. Law of Physics. And some of that energy is in the form of heat(due to friction from the movement of mechanical parts-turbine) which is lost into the environment. So that lost energy is not electrical energy.
Solar cell technology is still minute amounts of electricity.
if it was that easy, then we should demand that gas cars be self filling and never run out ever.

All the people who said the wind turbine would make things worse are completely wrong and out of their minds. Obviously, you would only deploy the wind turbine when the wind is at your back or you are stopped, but in both those cases, it would provide nice free power.
And if you completely covered your car with solar panels, you could drive for like 30 minutes a day. So 6 five minute trips for free. That would be a big help. For a lot of people, who basically commute 30 minutes each way, solar cells could provide half their power needs.

Read "Solo: Life with an electric car" by Noel Perrin. They tried the solar panel trick, and found it only provided about 10% of the power the car needed to run.
The wind turbine would be a net lose unless you were stopped. You shouldn’t drag a wind turbine around while you’re driving, for several reasons, but if you could pull it out of the trunk and stick it on while you’re parked, it could help.
