• the popular consensus is that, It takes more energy to power an electric generator, than the generator will produce.
  
  Where an alternator on a gas powered car will generate enough electricity to recharge a single Battery, an electric powered car uses multiple batteries, with the preferred power source being 48 volts, with a 36 volt power also being used.
  while an alternator on a gas powered car only charges a 12 volt battery. jcms
• Because there is always a loss of energy somewhere in the cycle. If there weren%26#039;t it would be an example of perpetual motion which is not possible. Energy is always required to turn the cars wheels and make it move forward. Even if the engine was 100% efficient it would only be able produce as much energy as it consumed and a portion of the energy it produces would have to be used to turn the cars wheels. In order to create enough energy to replace all the energy and propel the car it would have to produce more energy than it consumed.
  
  if you have an energy source with 100 units of energy and it takes 50 units of energy to complete one rotation of the wheel. Then the engine would have to convert 100 units of energy into 150 units of energy to both turn the wheel and replenish the 100 units of stored energy. This would mean that the engine would have to be 150% efficient which is not possible.
  
  The only way to get around stopping to recharge is to find ways to collect elements from the environment that can be converted into energy without disrupting the momentum of the vehicle i.e. Solar or Hydro
• There are systems that can be used on electric cars that are called regenerative breaking. The breaking of the car charges the battery some how. I really do not know the specififcs, I only know that they exist. Check it out on the net for more info.
• If the car is equipped with solar panels it will recharge the batteries. The %26quot;charge time%26quot; however will always exceed the %26quot;discharge time%26quot;. In other words every hour of driving will require several hours of charging.
• Actually there is a way to do it but it is a completely new concept that i am working on that charges it while you drive so you never have to stop again I currently have a Patent Pending on it :D
• Because there%26#039;s no source of power that would charge the batteries while driving. It would be very impractical to build a system to charge them while moving.
• Professor Actual-Factual from Berenstein Bears drives a Solar Powered car. It charges itself up.
  that is what the car makers need to do. make solar cars AT A DESENT PRICE FOR EVERYONE.
• Because of the natural laws of Physics and Chemistry. Where does the power come from? You would need to run another engine to power a generator.
• a hybrid can...but just a battery by itself looses juice....it stores power it doesn%26#039;t create it like a gas engine converts carbon fuel to movement
• thats why they are trying to build cars with hydrogen fuel cells.
  in order to make a car go through another means of energy.
• it is good idea,but we must redesign the whole parts of our car in order to do that....,i mean the battery insist....
• What the hell would it use for energy? Your smug sense of self-satisfaction?
