Who would have thought that the air we breathe could provide cooling for mobile mine equipment, power underground vehicles, produce compressed air and generate electricity. It sounds like science fiction, but Daniel Cluff, a Sudbury-based physicist and engineer, is ready for a mining equipment manufacturer and mining company to step up and trial the technology.

Using the Dearman engine, developed by the Dearman Engine Company, also of the U.K., liquid air can also be used to power underground mining equipment.

“It would be similar to a piston engine except you’re not using fossil fuel. You’re using liquid air. The radiator heats up the antifreeze instead of cooling it down and delivers the heat to the pistons to cause the expansion. The only exhaust is cool air,” said Cluff.

Electricity grids around the world are being stretched by increasing demand, the retirement of older power stations and the growing use of intermittent renewable generation.
