Here’s a new one for you; an engine that can run on the stream produced by boiling liquid nitrogen. The Dearman Engine Company is set to begin trials this summer on a revolutionary zero emissions engine that uses liquid air as fuel. It’s a new idea on an old concept, and it has a tremendous amount of promise.
The liquid nitrogen, also known as liquid air, boils at very low temperatures, producing steam that can be harnessed to power an engine. While notoriously inefficient, these “heat engines” have been around for quite a long time. Peter Dearman decided to spent some time improving the efficiency of his heat engine, and recent trials are showing great promise.
The Dearman Engine Company teamed up with the Imperial College of London on a three-month test that recently concluded. The next step is to put the Dearman engine to work on a refrigerated truck, where it will provide both engine power and cooling, a double whammy in the name of efficiency. Liquid air storage has also made remarkable progress as well, and could even compete with the batteries in electric cars.
This won’t be the last we hear of Peter Dearman and his liquid air engine, I can tell you that much.
