What, you don't think a 20hp generator can supply enough electricity to power a 270hp car?

Oh, a 20hp generator can eventually supply enough electricity to power a 270hp car. But the 2nd law of thermodynamics demands that it would require much, much more than 270hp worth of gasoline fuel to do so.

Yeah, I got it. The fact that they, apparently, driving while using the generator is more my point.

What I hear about this:

When you use a gasoline generator to produce electricity for an electric car, you first lose energy in the generator’s conversion process, but then the electric car uses that electricity more efficiently than a gasoline car would use gasoline directly.

Due to the initial inefficiency of the generator, the overall efficiency might not be as high as using grid electricity. But it still tends to be better than the direct use of gasoline in a car.
