Sigh -- ~33kWh of electricity has the same BTU content as a gallon of typical gasoline, so it is a direct comparison of the energy used in the car. Which is very useful information.
Sure electricity has embedded energy -- starting from the source through generation and distribution.
BUT the thing that many people also forget is that gasoline has lots of embedded energy in it -- it does not just materialize out of thin air, either. So, if you add the embedded energy into the electricity, then you must also do the same for the gasoline.
Neil Blanchard Designs: Oil Is Finite, Electricity Is Infinite
Back on topic: the basic issue with the the Miastrada design is, does it actually avoid the problem it is intended to? Or, does it merely separate the two parts of the vehicle, making everything much more complicated, raising the Cg, and increasing the drag, to boot?
You see, a large space above the ground and low Cg are mutually exclusive.
If you raise part of the car high up, but keep part of it low, then you would seem to have negated any possible aerodynamic benefits, since you still have things close to the ground.
