Yes, yes and yes. I have been experimenting with something like this on highway trips last summer and this summer and have gotten some of my highest tank averages ever. (Just shy of 1,000 miles on 16 gallons of diesel) I am using a chiller I got after an injury, used to reduce swelling. After I healed the device was just sitting around so I decided to re-purpose it. Basically it is like a small cooler filled with ice and water with an electric pump and two insulated hoses. When it is plugged in it circulates the chilled water through a bladder that I placed at the back of my neck below the headrest. It works surprisingly well and lasts for about 2-3 hours, depending on sun and outside temperatures.
