It does not use additional gas to create electricity. AS long as the car is on, the alternator gets its juice from the spinning of the Fan Belt that connects the alternator to the shaft.

So even at idle, it is spinning enough to create the juice to power things and recharge the car battery, or in this case, batteries.

My dad is a certified solar installer and he is working toward wind certification as well, so our home has two wind generators, 6 solar panels, and 12 deep cycle forklift batteries, that provide the majority of our power. Green computing FTW!

I wonder how long its going to take him to recoup the battery cost, a new alternator, and the install for said alternator because he looks like a complete idiot. (the alt will die soon because an alternator is not meant to charge a dead battery, its mean to tender a mostly charged battery)

He'll be in the red for sure. Plugging it into the wall would be cheaper.

An Austrian style battery....you have someone locked in your cellar that generates power for you.

In recent months, I've looked into Solar. A system for my home, be it all or nothing, would consume about $18-24,000 plus installation So I dream on

an alternator generates electricity as long as the engine is running, 14v is correct, BUT, electronics run off of the battery during transit, the alt just charges it, its to much strain on an alt to just run all electronics from it.

thats why when you jump start someone with cables, your not suppose to have your car running, its hard on the alternator

Yeah, I had that brilliant idea that I presented to my parents until they looked up how much power the computers actually consume and said that it isnt worth it.

was an idea that I had but I dont really know how to make it work.

Realistically, we need to find a way to that the energy that the computer puts out (heat) and make good use of that. In the winter its easy (heat the house) but we need something constructive for the summer.

The only use is to warm a room. That's why it is wasted heat... There's nothing that it can be used for constructively without hurting performance. There's PLENTY of sources of waste heat (factories, HVAC, office buildings) where it would take more effort to recapture the energy. It's entrophy...

I had a crazy idea the other day and it would pertain to this subject quite nicely.

A motor, an alternator, and a relay... Jump the motor from an external source (Battery, PSU, etc) and use a belt to turn the alternator. Then, the relay kicks in and kills the external power while the alternator provides the juice.

The electronics does not run off the battery, as you say it.
the Battery is linked parallel [look on wiki for linear and parallel circuits if you have questions ;o) ].
The whole Car runs perfectly fine without a battery (only that you can't start it).

A medium class car has a 45 - 70 A alternator.
And they are chosen to power all your stuff in any case.
Only if you put in a very strong Audio Amplifiers, you can get in trouble ;o)

I learned to run the spending car to not kill it's battery.
That way also the battery of the earning car is charged way faster and less power has to run over the cables on a starting try.

You mean you want the System to power itself after removing the start power?
That's not working^^
Parts of the energy is turned into heat and a magnetic field.

If you're already out of school you didn't listen in the physics class ;o)
