15 kilowatt generators are cheap, very quiet, and efficient (1.5gl/hr consumption max, maybe even 1.0).
Commonly used on bus and motorhomes to power their systems and recharge their huge battery banks. Cant one of these be fitted (or modified to fit) in a tesla S with a fuel tank (diesel, 12 gallons). This will extend the range of the vehicle. If I know I desire to drive 500 miles, I could set the tesla to start charging once battery starts to deplete. I understand that 15kw will NOT be sufficient to keep the vehicle fully charged forever, but it should slow down the discharge such that we effectively are getting 600+ miles of range.
And it would even be possible to fill up before a night's rest and let the generator charge the battery -- i estimate it would take about 8 hours -- with some engineering (building muffler like a standard vehicle), it could be very quiet 60dB or less that it would not even be noticeable if it was running unless you stood next to the vehicle.
The idea of charging stations is not the future. This can be an option because i recognize it would probably add about 8-10,000$ to the cost, but I think this would be a huge winner
