Brayton Energy will develop a 1 kW recuperated Brayton cycle engine to produce heat and electricity for residential use. To begin the cycle, compressed air is preheated in a recuperator before adding fuel, then the air-fuel mix is ignited in a combustion chamber. The high temperature exhaust gases then expand through the turbine, providing some of the work that drives the compressor and also produces electricity in a generator. Major project innovations include the use of a rotary screw-type compressor and expander that operate in a sub-atmospheric Brayton cycle i.e. below atmospheric pressure. In addition, Brayton will also use their innovative patented recuperator that is currently in production, and an ultra-low emission combustor.

Dartmouth College is developing specialized alloys with magnetic properties superior to the rare earths used in today's best magnets. EVs and renewable power generators typically use rare earths to turn the axles in their electric motors due to the magnetic strength of these minerals. However, rare earths are difficult and expensive to refine. Dartmouth will swap rare earths for a manganese-aluminum alloy that could demonstrate better performance and cost significantly less. The ultimate goal of this project is to develop an easily scalable process that enables the widespread use of low-cost and abundant materials for the magnets used in EVs and renewable power generators.
