Electric battery packs exhaust their embodied energy without materially affecting their weight. They should be compared to 1/2 tank of fuel, which both Ford and Diesel felt should be sourced from hemp seed.

We are operating at an overall mechanical efficiency of only four percent… Therefore, we find that if we increase the overall mechanical efficiency to only twelve percent we can take care of everybody. That three-fold increase in the overall efficiency can only be accomplished by redesign. – R. Buckminster Fuller
