There is a man who fills up his tank once every two months. One tank of gas, literally, lasts him two months. He is freezing the price of gas by freezing something else. David Hutchison is a Cryogenics expert. He built this Cryo-Process himself. A few years ago he began an experiment on his hybrid Honda, freezing the engine components. The results were a fuel-efficiency dream. A hybrid Honda typically gets really great gas mileage anyway, around 50 miles to the gallon, but David Hutchison's cryogenically tempered engine has been known to get close to 120 miles a gallon. Racers have picked up on David's trick of cryogenically freezing car parts. It is now widely accepted among NASCAR and Indy-car racers.
