Former ship's electrical officer here. We transfer 1000x that much energy to vehicles (ships) from stations (pierside "hotel" power) all the time. Electrical transfer is far safer than transfering the same amount of energy in chemical form (e.g. gasoline) and letting any lunatic walk up to publicly accessible nozzles and point them whereever they want with or without a lit cigarette. * charging leaves zero risk of explosive residue * it's ridiculously easy to apply interlocks at every step of the transfer. * the exact rate and requirement of energy transfer is very easily calculated and monitored and self-balancing. Ancillary variables like temperature and thermal expansion are equally cheap and easy to measure with very high precision. * At scale, the marginal cost of solar power gets really close to free. I have plenty of neighbors who are getting rebate checks from the local utility instead of paying them. * Energy density remains the biggest hurdle, but it's already provably good enough. The pricepoint is high only because of the small scale of production and the high-end stuff (leather seats, etc) wrapped around it.
