How Some Inventors Say We Won't Lose Moisture In the Desert While Winning The Superhighway Competition

Dale Ernhart is using a cooling suit that also stops fire (a real cooling suit always will!). The cloth will have an inner layer that will allow better air circulation than conventional suits, drawing heat and moisture away. Conventional suits have a quilted layer of cloth that stops fire but that also causes dehydration, this causes drivers to lose 12 pounds of water and some drivers to be confused or with slower reflexes by the brain's loss of computing power to win the competition. Who says surfing the web and reading won't make you a genius!

When it's hot the wind blows when you have perspired, wouldn't it be nice to have that high level of cooling power? One invention uses the bodies own moisture not to wick away and promote heating (works well to stay warm in winter!) but rather for cooling. Somewhat like the inventor of hook and loop, who went outdoors and got burrs, reminding him of hook and loop the inventor of this cooling motif was trying to devise a way to stay warm by using layers of thin plastic around his socks outdoors in winter, but sometimes his feet would overheat even with much moisture held inside the sock. So to be cool he took off his shoes with the layer of thin plastic and moisture inside, with dramatic cooling. It just took about 20 seconds to cool most of the feet compared to 10 minutes with just dry socks. In the scorching heat most always sense the depth of water with both feet or jump in the pool without a wait! This motif of using the bodies own moisture could be used in a summer suit with an inner thin absorbing layer to not get too moist, a layer of thin waterproof plastic to seal the water in, and the usual outer fire proof layer. A fan blows air between the plastic layer and the fire proof layer, much cooling the driver. They have even devised one way pressure pumps that use some of the g forces the drivers must tolerate like in their legs with the vibration to continually pump air to the cooling layer without an external pump, a real actual airbag for feetwear. Dino and Wilma and Betty will celebrate! Unlike some cooling suits that use ice water or a coolant, this needs no heavy box of ice water to lift in the heat to be portable.
Why not just pump air to the suit? Because water is much cooler than air, and the water is already just where evolution would find it of most worth to the wearer. For people who live in the desert this would have an inner waterproof layer and an outer airsealed layer with air pumped between both. If there were too much moisture on the skin with this sort of science it could be continually recycled with a small still or other machine perhaps solar powered, so almost no water would be lost in the heat while the wearer would be cool.
