(CNN) - He's called the "nutty professor" by one of his sons, but inventor Peter Dearman has developed a renewable energy source in his garage.
Dearman calls it liquid air energy, an experiment created from a mixture of liquid nitrogen and antifreeze.
The mixture of the two, Dearman has discovered, allows for liquid nitrogen to transform into an even stronger power source. The combination is powerful enough to start a car.
Dearman bases his invention on the idea that fossil fuels won't last forever, and more sustainable energy sources need to be developed.
The inventor sites that liquid air energy is cheap, clean and efficient and the only waste produced is cold air.
