Sounds like an upgrade to my cold towel idea

Slit the seat cushions and sink the tubes in. Very clean. I'd say exit the tubing under the seat to a "terminal block" of hoses. One block for "in" and one block for "out". You could consider using one of those 12V coolers instead of ice water or some fancy paltier thing. Put it in your back seat or trunk. I have grabbed a small 600gph bilge pump from the boating section. I'll let you know how well it moves water through small tubing.

For winter you could use the anti-freeze that is used in RV water systems.
Its non-toxic.

In winter you could just drain the tubes and take the cooler/pump system out of your car.

Not if you want to use it for heat.

He's got heated seats already. But for someone else, yes, good point.

$119 is probably about what I will end up spending it will probably never pay back in the golf, but it will be very comfortable and very cool.

Good Thought!
I have some copper screen; might be just the ticket. I'll have to play err Umm Experiment, with it and some foam to see if it is destructive or not..

as long as they don't sink to far I'm sure that it will work well

There is some extra space (little loose) in the crease area between the seat and the seat back. I'm planning on doing 4 Manifolds 1 lower out 1 lower in 1 upper out and 1 lower in. basic plan is to have a larger tube (1/2"?) and a series of t's to make a long manifold across the with of the seat.

Those electric coolers are pelter based.

Please do let me know how the bilige pumps work for small tubing.

The issue that i have with peltier based coolers is that hte heat has to go somewhere. That's why i'd rather just be cycling ice blocks in my basement freezer. Let the heat go into the water, then dump it out when done. Otherwise you're heating your car's cabin space to cool down your seats. Reminds me of the morons that I saw leaving a fridge open to try to cool down their house.

I really need a 12 volt pump; I could do an inverter, but that's kind of a waste.

On that note I am running a 12volt fountain pump on a wall wart (came in a gift table fountain) as a recirculating pump for a vibratory tumbler. It is not in line, but I'll look at it.
