Electric cars how to create more energy than you consume?

jamesalburen asked:
Listening to all the talk about electric cars and how physics doesn’t allow alternators to renew their batteries leads me to ask a few BIG questions: How do we get the alternators to produce more energy than the car can consume? Also, Why can’t we make the axles work for us to turn the alternators using a drive shaft? Why wouldn’t stacking alternators work?

Simply put you cannot lift yourself off the ground by your own boot strap.
And it is the same with battery, motor and genertor/alternator. Trying to generate MORE electricity than it take to spin the generator is like trying to lift yourself off the ground.

There has been lot smarter people than you AND me that investigated this issue.
Good Luck….

This is the age old question of the perpetual energy or perpetual motion engine. So far it is not possible. At least for now (I am hopeful though) with anything from conventional cars to the electric car, you cannot get the complete energy potential out of it. there will be loss of efficiency sadly. the idea is to make it as efficient as possible. Hence the kinetics brakes that regain energy every time you brake etc. If you come up with a perpetual motion car, you’ll either be filthy rich or dead within a week from announcing it.

in simpler terms
the amount of drag created by the charging system
would stop the car from moving

“So far it is not possible”
bad news; it will never be possible. getting more energy out than you put in would violate the laws of physics (the 2nd law of thermodynamics, specificaly)

doesn’t work, it would violate the laws of conservation of energy, or “you don’t get something for nothing”.
analogy:
Start out with a £5 note. Go to a bank and change it for five £1 coins (minus a service fee). Go to a different bank. Change your coins for a £5 note, minus another service fee. Repeat until you have several million pounds!
