Even it sounds childish or unbelievable it is true, and it’s true since 1932 when J.M. Custer of Piggott, Ark. had an idea for a car that would run on compressed air, requiring no external charging and no fuel. What’s surprising is that he succeeded to ran it.
For the engine it was necessary six years of researching but the result is impressive: four air tanks filled with compressed air power the car 500 miles at a speed of 35 miles an hour. As the warm air went through the engine and cooled, it was recovered and drawn into a compressing chamber, where it was reheated again and returned to the tank.
Maintenance cost almost nothing, being a engine using air, cooling system, ignition system, carburetor, etc are getting useless. The Custer air car technology shows how Magnetic Air Cars are working using air-bearing turbochargers to create mechanical energy. After 75 years, the technology revived and now using high tech, it’s trying to improve the concept reaching an(other) eco way for protecting our Home.
