Close call there. I believe it is close to even, though it would take an
engineering study to see the net effect. After all, it takes quite a bit of
energy to haul around 1,500lbs of battries.

That would be more efficient that recharging off of the grid. Better yet,
would be a hydrolic drive system using the turbine for power. That was
demonstrated in 1970 or so by Embry Riddle Aero Univ. It was very efficient.
I believe Ford's Turbine 18 wheeler semi-truck uses a simular system.
