Applications

reXorce’s Thermafficient™ systems has the potential to create meaningful change across a broad range of power generating applications including:

• Industrial waste heat recovery with greater than 30% increases in efficiency gains.
• Solar thermal as a source of power, projecting up to 200% efficiency gains versus solar photovoltaic.
• Low temperature geothermal applications with greater than 25% efficiency improvements.
• Consumer appliances, from HVAC to refrigeration, and hybrid HVAC having increased efficiencies.
• Internal combustion engine alternatives with thermodynamic efficiency projected at greater than 65%.

Unique Capabilities

The system will generate electricity at superior efficiencies using thermal energy from waste heat, biomass, solar and geothermal sources in addition to fossil fuels.
The combination of reXorce’s proprietary components and the integration with the NASA patent leads to the following value potential based on extensive thermodynamic modeling. The production of the working prototype in Q2 2008 will serve to confirm the predicted model.

• Thermafficient™ will enable conversion of waste heat recovered from a range of sources, such as a coal-power plant or industrial process, to yield additional electricity without any increase in CO2 emissions.
• Thermafficient™ will provide active cooling and up to 20% more power generation per square meter for the next generation of concentrating solar photovoltaic units.
• Thermafficient™ solar thermal is projected to be up to 2X more efficient than traditional and flexible film solar photovoltaic units at reduced $ per kW capital costs.
• Thermafficient™ is projected to increase the power generated capacity from existing geothermal plants by utilizing lower operating temperatures.
• Thermafficient™ will significantly lower capital costs for distributed power generation that has additional cooling requirements such as large retail stores.

System Advantages

When comparing Thermafficient™ to the narrowly defined category of thermal engine systems such as the Stirling engine, the advantages are significant:

• Provides free cooling which most other competing systems do not.
• Uses less moving parts with less maintenance and lower capital costs.
• Operates in broader temperature ranges, allowing for integration with a range of renewable sources as well as the ability to extract energy from 250°F versus 350°F temperature sources.
