Ugh, tech reporting. Is there a original source for this somewhere? Theres some limited info at http://www.teslamotors.com/supercharger http://www.teslamotors.com/supercharger. 100 kilowatts good for three hours of driving From the announcement video, it seems they are charging at 370V with a maximum of 225 amps = 83.25kW. So that 30 minute figure for half a charge is pretty real. The cost for one such charge would be approximately 3$ with industrial prices for electricity. Given that you can feed solar power back into the grid at rates above or equal to what normal customers pay for their electricity, I could see them making break-even on this when discounting the initial investment (which will pay back hundred-fold in adoption rate for their cars).
