Sometimes I like to reinvent the wheel, I don't know why.

So I hate being hot. Worst thing is wearing a helmet where I can't feel air on my face. I can't imagine what it's going to be like with a full racing suit. So my plan is to buy a G Force helmet with an air hose attachment and my wife can make a shirt with fish tank hose running through it.

I then want to mount a removable cooler of some sort in the car with a drain valve. I'm going to use the windshield washer pump as the water pump for the shirt.

So, another idea I have is instead of ducting air hot air from outside, I'm was thing I'd rather have cold air go through my helmet. I'm going to mount a small fan on the side of the cooler, pulling air from inside the car, through the cooler, then suffer through my helmet. I imagine sitting in the car staging, everyone else will be roasting, and i can flip a switch and be comfortable. I'm pretty sure I can make this whole set up for very little. I would image just a few lbs of ice and water would last the length of a race.

What do you guys use and how well do they work? What about weight?
