Sandia progressing to demo stage with supercritical CO2 Brayton-cycle turbines; up to 50% increase in efficiency of thermal-to-electric conversion

Green Car Congress

MPa enable the system to operate with very high thermal efficiency, exceeding even those of a large coal-generated power plant and nearly twice as efficient as that of a gasoline engine (about 25%). A number of DOE labs, including Idaho National and Argonne National, have contributed to the body of work.

DOE to Award Up to $27M in Phase III Small Business Awards; Algae Processing, Fuel Cells, Improved Materials for Motors, Synthetic Fuels Among Areas of Interest

Green Car Congress

Improved Magnetic Materials for Motors. High-temperature, high-strength, lower-cost permanent magnets (PMs) are needed for traction motors for HEVs and PHEVs. Grant applications are sought to economically produce core material and magnet material with high resistivity that would improve motor efficiency and reduce fabrication costs.

The Case for Nuclear Cargo Ships

Cars That Think

“At the same time, it’s becoming apparent that alternative-fuel solutions we’re looking at have big drawbacks, and that producing these fuels will take a lot of green power that will be needed to replace coal and gas on shore. The reactor would produce steam to spin turbines that would generate electricity to power motors.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In The impetus for this change came from a study by the US Idaho National Lab [ 2 ]. Smaller and lighter, it requires less liquid fuel.
