Maybe this would work better with a portable heat pump. A device strapped on to your waist that takes in your blood on one end, heats it up, and then pumps it back out the other and into your body. And in the middle of winter when you find yourself with a layer of ice stuck to your car’s windshield you can pop off a hose and spray the car down. Instant de-icer.
