The machine was invented by a team of engineers led by Mike Nowak, customer proposal manager at Weldun.

Many gas turbine engines use a recuperator, or heat exchanger, to extract heat from exhaust gases and preheat the combustion air. Recuperators include a core that is commonly constructed of thin, flat sheets of metal with an angled or corrugated spacer between them. The sheets are joined into cells and sealed. They then form passages between the sheets. The cells are then stacked or rolled to form alternate air cells or hot exhaust cells. Air discharged from a compressor in the engine passes through the air cells, while hot exhaust gas flows through the alternate cells. The exhaust gas heats the sheets and spacers, and the intake air is heated by conduction from the sheets and spacers.
