British inventor Peter Dearman, the man behind the Dearman Engine Company, has developed a system of propulsion out of thin air...literally.
Here's how it works: when you cool air to -390° F it turns into a liquid. Dearman pours that "liquid air" (liquid oxygen, nitrogen) into a holding tank onboard a vehicle. The liquid is then converted back into a gas via anti-freeze. This expansion and release of air turns a motor that powers the car.
Dearman shows off his air-powered car to ABC News in the video clip below:
"With Ricardo and a cluster of Universities, the company is now currently working on sub-system optimization and a fully characterized demonstration engine is scheduled to go into testing during mid 2013 to provide the ground-work for field trials," says DearmanEngine.com.
