Here's something that may generate some creative ideas. A year or two ago I bought a chilipad. Check out www.chilitechnology.com for info. A peltier unit is in a cube (about 10" cube) that generates cooled or heated water which is circulated through tiny silicone tubes built into in a mattress pad. The tubes are barely detectible even without only a sheet on top.
It does feel slightly wet sometimes but it is so slight, I feel a fan blowing through the seat would take care of it. No mold or mildew even in the humid south where I live.
It definitely works in the summer. As I have two dachshunds who stick to me like velcro, I don't need it in the winter.
I think a combination of chilled water circulated through a pad PLUS a bit of air moving across the tubes will cool the driver plus handle any condensate.

How about making a seat of out aluminum tubing, so it is structural and light,
and circulate the cold water in that.
My own idea is to just cool the back of your neck, this cools the blood which has a built-in circulation pump. If this pump is not working, a/c is not a concern.  |

that's a good idea. i run across them from time to time.

I started 6 branches, might add a 7th, then attached 30 feet of 1/4''OD PVC tube on my 13x22 inch bottom pad.
I am sure I will get at least 30 to 50 more feet on there.
Also might extend the pad several more inches for under leg cooling.
Shouldn't be too difficult to get that uncomfortable cooling I am after, I can always turn it down from there and you cant use cooling capacity that you don't have.

Oil pan, thanks for this write up. 
I think I'm going to follow your build and make one of these for myself. My Talons
mid mount turbo system is working great but the heat is killing me. 
This will be a excellent way to keep cool. We have had one of our hottest Summers this year and its taking its toll on my body and check book.

No A/C and cool as hell, but still I doubt whether the FE is much improved.

City mileage would be impaired, but hey, if you get in an accident, nobody will know if you wet yourself.

The first part of the bottom heat exchanger has taken 80 feet of 1/4''OD PVC. That's not counting the feed and return lines hanging off the side.
Seems adequate.
