So just thinking out loud, and this might not be best source for fact based experiences, but I had an idea.

With a track based car, no rules to follow other then common sense/safety/cost/weight, I was thinking for a Florida car, with an old fart driver, with an alum Kirkey containment seat, and less then 30 min track stints, could I just drum up some seat back Ice pack slots attached to the seat back, figure out a basic ambient air insulation solution, incorporate an easy melted ice pack swap between stints design, and be done with it?

Sure it won't be slick or controllable, and will add some weight, but its simple?, reliable, and less then the multi thousand dollar powered systems, and be better then nothing, and its hot In Florida in a 3.5 race suit, in an enclosed non AC car


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
