It would cost money, but I'd bet less than gasoline.

The station could use a mix of solar power, wind, power grid and charge the batteries for probably much less $/kWh than gasoline in a car.

It would be interesting to try to work out for certain types of people the cost of powering an Tesla.

When you fill up a petrol / diesel engine you have one option: petrol / diesel.

When you fill up an Tesla (and other electric cars have different possibilities) you have:

- Recharging on your home power, which would cost whatever your home power costs but can only be used when you are OK charging over night - Recharging at one of those Tesla fast stations, which costs nothing, but takes 40min - Swapping a battery at a Tesla station, which takes 90 seconds and costs $??

The price then depends on the mix of those three strategies, which is determined by your usage (drive to and from work every day, it's your home power etc)
