    One can only hope this is not another EEStor, the words "Startup company" no longer inspire confidence.

    Interesting, but I would be very wary of standing next to a car where a battery is being recharged with 15kWh - 50kWh in one minute.

    Me too, but that is "just" an engineering issue. Think laptop batteries. You can snap them in and out in seconds, recharge them inside an explosionproof safe if you like. You can trade your empty 5-gallon propane cylinder for a full one at many filling stations around here, and the empties are refilled by people who know the risks and who can do it safely.

    As I recall, when petroleum-fueled autos were becoming popular, people said much the same thing about pumping gallons and gallons of the most energy-dense liquid fuel around, with explosive vapors, into a cranky, accident-prone horseless carriage.

    And before that, they were worried about the tons and tons of debris piling up from the "horsed" carriages too.

    Gasoline is amazingly safe stuff for its energy density. If one pumps electricity 15kWh electricity into something in one minute, then at constant power which is optimistic that is 900kW. Even just 10% loss is 90kW waste heat in the wiring and batteries. That's enough to be very concerned about.

    15kWh/min here fixed that for you;)
