nope. the alternator upgrade was to cover lights and stereo, besides, its a jeep, who needs a/c when you have no top or doors? :)
You actually have a system?.......
No, no, no. It works like this: You turn the little knob to all blue then the fan switch thingy to the picture of the Big Fan. Cold air comes out the hole in the dash and you make the slats turn to blow in your face. THAT'S how it works..........
you're kinda right. but it doesn't "move heat". think of it like this. what happens when you add cold water to hot water? it equalizes the tempreture, it doesn't displace it. a cars a/c unit sucks the heat from the (outside) air, then pushes the cold air into the vehicle, combining it with the warm air in the vehicle, which equalizes the difference between the two air tempretures. the excess (equalized tempreture) air is bled out of the vehicle (like what would happen if you kept filling the container of hot water with cold water until it overflowed.)
Watt, er, what would be a cooler idea is to figure out a way
to use the engine/exhaust heat with additional peltiers to
generate the power needed to run the cooling peltiers.
My parents built a energy efficient home in 1985. Part of the design included a geothermal "heat-pump." Since the well provides plenty of water their system is configured as an "open-loop" design. However, I have seen systems that skip the coolant-to-water heat transfer and circulate the coolant itself in copper ground loops.
Another great invention car companies are beginning to use:
remote keyless entry that instead of flashing the lights, turns on the reverse lights with no brake light. I was driving through a parking lot and saw a large SUV (Yukon Denali) with reverse lights on and no brake lights. Waited... realized the driver was not even in the car. I have seen this on a couple other cars.
My idea years ago (I live in Florida) was to bury a matrix of 12" PVC pipes in the ground, deep enough to be below the water table (about 4' or deeper during dry season here) The temperature of the water is always about 68°F year round. A circulation fan would direct air through the pipes and back into the house duct system with appropriate dust and critter filters.......
The peltiers could be mounted to finned heatsinks that are in the air stream or a duct that directs air to them from the front of the car. The faster you drive the more cooling the get.....
I don't have the URL handy, but one site showed a unit being installed in a NYC townhouse! They drilled into the sidewalk to place the ground loops. The catch with geothermal HVAC is that the initial costs are huge compared to traditional systems. However, my mom's winter electric bill was the same as mine (geothermal "runs" on electricity) but I still had to pay for propane. Ouch!
I've read few articles on generating applications. Mostly propane-based, out in the real remote locations.
Also for wood stoves, but the overheating issue is a biggie. Too easy to cook your investment w/o much of a return.
Anyway, you're stuck in traffic, and there's not much [cool] air moving across the the cooling fins, and you end up
like the guys with baked peltiers on wood stoves.
I'd rather have an RTG, myself... :)
A GTO with an RTG. What a combo!
I must have missed it. Where is the FREE energy mentioned here? I had impression that it was about improving the efficiency. Please explain where I am wrong.
I think myself6 should also stand next to a diesel electric power unit on a train as the engineer accelerates the trottle.

Lets say your engine is running at 2500 RPM.
You plug in one of those DC powered tvs to the lighter jack and turn it on.
The car is still running at 2500 RPM driving down the road at 55mph.
There was NO EFFECT on the mechanical load of the engine, therefore MPG was not effected.
If you increase the electrical load on the alternator beyond what it is rated for (you will probably blow a fuse before this happens) your engine will eventually stop running and your battery will be dead.
I refuse to drive a car that modifies the RPM of the engine according to the electrical needs. F--k THAT!
Within the alternator's rated capacity, if you perform the above steps, switching on the TV will increase parasitic drag on the engine. The drop in rpm will be barely noticeable, because the engine control opens the throttle to compensate - as if you were climbing a hill. You're holding steady at a given rpm, but you're burning more fuel to maintain that rpm given the increase in load.
How is Sherlock doing these days? I hope all is well.
I'm suprised that after nearly 200 posts someone has not mentioned the 480 system that I have on my car. Four windows down and 80 miles an hour.
His position was equivalent to the free energy position, and the knowledge (ok, faith) that perpetual motion machines are impossible to make serve to expain why his own position was wrong. If, in fact, it took the same torque to run a generator irrespective of the electrical load on it, then you could make a perpetual motion machine in the following way:
Get a small motor, and a bigger generator. The small motor is enough to overcome the friction in the larger generator with no load. Now, turn on the generator -which supposedly doesn't change the torque required to turn it. Since it's a bigger generator, it can not only power the small motor, there is power available for free on top of that.
The fact that the above is impossible can be used to prove that the torque must change with electrical load; the perpetual motion scheme falls on the assertion of torque being independent of electrical load. In fact, when you connect the generator to the motor (that is, when you draw a load from the generator) the little motor will no longer be able to maintain RPMs - it will soon stop if there is no other power source.
