Heat Engines/Pumps

The key innovation of this technology utilizes is its ability to capture and transfer heat through the engine without a change of state, thus avoiding the inherent shortcomings of steam generation at lower temperatures. Because of this we can obtain meaningful output over the full operating range. Our prototype at the CERL lab operates with both heat source and heat sink well below 100C although it is designed to operate with heat sources at 300C as well.

In accordance with laws of thermodynamics, low differential heat generation has a corresponding reduction in net conversion efficiency. Our focus has therefore been to optimize the rate and volume of heat that is processed through our engine in order to compensate. So although the net efficiency will be lower, the net cost will be superior and provide respectable capital cost recovery.
