At least taking their figures at face value, about 75kwh to generate a gallon of gas, and let’s say 67 kwh to get a an EV 200 miles (assuming some losses between the generation and the actual battery capacity, and 3 miles/kwh which is on the low-ish end of EVs, but realistically close). The most aggressive hybrids getting 50 mpg so we end up with it being about 4x worse than charging an EV with that energy source.

At least at residential rates where I live, that’s about $10, so it would only really make sense when gas gets to $10/gallon, otherwise, go to the pump for the fossil fuel. That’s ignoring the cost of the station itself.

So maybe nearer than one might imagine, but still highly impractical. Maybe if they doubled the efficiency and gas eeks up without residential electricity rates going up…

But all this is assuming it will work exactly as well as they say it is, and I’ve learned to have a healthy dose of skepticism… Here though I can be as optimistic as they like and it’s still a tough sell…
