Notice no mention of getting rid of the internal combustion engine all together. it is the most inneffecianet design EVER created. More than 90% of the energy in gasoline is lost to HEAT. Thats right, only about 10% of the energy in gasoline is actually used to 'propel' the car down the road. This is why you have many additional heat exchange systems on your car: Coolant radiator, transmission cooler, oil coolers, power steering coolers, etc. Ask any automotive engineer about the effeciancy of the internal combustioon engine. So, the REAL issue is them keeping us on oil. PERIOD.
