So we are looking at 650 watts per square meter * .6 which is 390 watts as the current max and future max might be something like 600 watts per square meter which still leaves a car or boat very underpowered.

"The car motors are rated to a peak power of x watts. They don't need to run at peak output otherwise you couldn't get the rated range figures."

Is this because of air and road friction or does the motor loose efficiency at peak output.
