Electric Car That Never Needs To Be Plugged In?

[JeffElectric]

I'm sure that most of you have knowledge of Telsa Motors all electric sports car that is capable of a 200 mile range +/-.

My point is (and putting the laws of physics aside for a moment), why couldn't the similar technology developed by Telsa engineers in addition to the regenerative braking system in the Prius to charge the batteries, plus designing and most importantly a system that would kick in at sustained speeds (let's say 35 miles per hour and above) a pulley system connected to a high-output generator that would be the main re-charge for the batteries essentially providing unlimited range as a self sustained system of charging.

I'm not an engineer, but I can't stop thinking of this idea.

Appreciate everyones opinion and technical expertise.

Because it defies the laws of physics? That may be one small limiting factor.
I think Tesla already has regen braking.

Man-made laws can be broken, but not the laws of physics. It looks like you are describing a perpetual motion machine. Google that phrase and see why it's a non-starter [pun]

No one has managed to prove Mr Newton's theories on energy to be wrong yet.
Moving a body through a fluid will make the fluid move converting the energy moving the body into energy moving the fluid and heat. Tyres rolling down the road get hot radiating energy into the environment.
Energy can neither be created or destroyed so that energy must come from somewhere.
Energy to turn a generator must come from somewhere.
Have you ever ridden a bicycle with a generator light outfit? The energy to turn the generator comes from your legs, you can feel it!
This is all about grade 6 science.

The way to understand this is to think of a bouncing ball. Each time it bounces the height gets smaller. Why? because there is some energy loss/transfer when the ball hits the ground. Eventually the ball stops.

The same thing would happen with your pulley system. The pulleys would transfer/take some of the energy as they go around. Thus there would be a net loss of energy.

Energy is not something that is free. It has to come from somewhere.

But that would be naughty wouldn't it?

There is a much cheaper way to achieve the same thing, and it's already been mentioned on this forum at least once. You put a magnet on a stick and place it in front of your car, and it pulls you along. Same thing, no moving parts, and much cheaper. If you want to go faster, you use a bigger magnet.

I guess you've never heard of the three laws of thermodynamics.

There's a guy in the autoinsight forum that has, more than once, mentioned his concept of installing wind turbines on a car to capture the wind and recharge the batteries as the car drives.

I have tried in every possible way to explain why this can't work but he's undetered. I'm not sure how so many people made it through high school without some minimal understanding of these basic principles of physics.

If it was an electro magnet like they use to lift scrap metal you could use the energy from the battery to make it stronger like 200 volt strong or from the inverter at 500 volts, wow, how fast could you go?
