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%). Sienicki (2009) Investigation of alternative layouts for the supercritical carbon dioxide Brayton cycle for a sodium-cooled fast reactor.

How clean is EV battery manufacturing?

Electric Auto Association

of burned gasoline into energy to turn the wheels, electric vehicles (EVs) use 59-62% of the electrical energy from the battery to do the same. Gasoline always emits 20 lbs of toxic air pollutants per gallon, and can only be burned once. Whereas, battery EVs fueled on average grid electricity emit 105–124 g CO2 eq./km,

Electric Car Manufacturers Inspire New Paradigms -- Seeking Alpha

Tony Karrer Delicious EVdriven

The electric car features three different battery options, two different Lithium-based (LI) systems – A123Systems and Enerdel as well as a Sodium-Nickel battery Zebra (Mes-Dea). In the end, gasoline won out because it was the cheapest and delivered the most energy per unit, but it took 20 years to sort out. We have oil!
