Cyclone’s Waste Heat Engine (WHE, pronounced “we”) is a low temperature, low pressure, self-starting model of the Cyclone Engine.

Because the WHE runs on heat as low as 225 degrees, it can pull its power from many different sources of “wasted” heat or renewable fuels, such as:

• Commercial or small-scale industrial ovens or furnaces - see how this works

• Concentrating solar thermal collectors

• Engine exhaust – transportation or power generation

• Biomass combustion – dry and raw waste disposal

The WHE is capable of producing up to 16 HP of mechanical output, which is sufficient to power a 10 kW electrical generator. This means that one engine offers the potential to supply a significant portion of the energy requirements of a home or small commercial facility. Two or more engines in-line or networked can be used to generate greater power output. Connected with an engine exhaust system, the WHE can substantially boost the overall efficiency and lower overall emissions of the prime mover engine.  

We are also working with our licensee Waste Heat Resources to develop large-scale waste heat engines, based on our Mark V and Mark VI configurations. These engine systems will harvest heat from massive industrial furnaces, foundries and other heat producing (and wasting) equipment. To see more of what WHR is doing, click here.
