Shame on all those who actually learned physics, where the Second Law of Thermodynamics clearly tells that a kWhr of electricity can produce a kWhr of heat but a kWhr of heat can not produce anything close to a kWhr of electricity, but fail to speak up in the face of this widely used trickery in promotion of electric vehicles.

The equivalency is a mathematical conversion. There is no losses in a mathematical conversion. You are getting your knickers in a twist about this, and I don't understand why.
Of course, if you do an *actual* conversion, there will be losses. But we are not doing actual conversions. So, again -- the energy contained in a typical gallon of gasoline IS EQUIVALENT TO about 33.4 (or 33.7) kWh of electricity. This is a way to compare the energy contained in each. It is NOT an actual conversion of one to the other!
The reason they (the X-Prize folks) was that we are all accustomed to gallons of gasoline. Nothing more than that. Nothing sinister or sneaky. They have to convert everything to one common denominator -- so they can decide/show which is more efficient.
An ICE powered car doesn't have to account for the energy it takes to actually produce that gasoline, so why should the EV have to account for the energy it takes to produce the electricity? Can you please answer that question? Pretty please, with sugar on top?
