Not to dissuade you from building such e devices, but :
Some thoughts on electric driver anything. In short efficiency . that is the power created in you e device seems prodigious but when you look at the power consumed to generate the electricity weather by wind coal or even water, plus the losses in transmission, the net power of your device comes out a negative number.
Batteries are a joke for transportation devices. the only thing that currently works is a hydrogen fuel cell. I'm not sure of the power required to create liquid Hydrogen. Maybe when nuclear fusion become a reality, or wireless transmission of E power is a fact (ala Tesler) .
As long as paying for power is fact, nobody is going to make much headway on creating a free power system.
I see all e transportation devices short of Public trans as a very expensive toy
