    I do not know what modern homes in Germany have.

    I guess we should also ask them exactly what they mean by "high speed"?
    Most homes in the UK have only a 60A service fuse at 230V which gives a maximum of just under 14kW - by the time you subtract the power taken for cooking, lighting, entertainment, etc. only a "slow" charge is possible during the evening (more in the "wee small hours", but still not what I would say is enough for a high speed charge without battery assistance).

    Changing gears a moment. When I was in the UK for the Automechanika Birmingham, I ended my trip going through London. Some colleagues and I went to check out the Fully Charged Event at Silverstone Raceway. I thought you might like to see some of my photos from the event. I hope my writing and photos are somewhat interesting... Check out the 600hp 1973 Beetle!

    Just as a note on the charging front: My Tesla wall charger at home is 11.5kW (60 amp breaker on 240v) and gets me about 44 miles / hour plugged in. It's paltry compared to even the worst urban supercharger, but still faster than any 'level 2' chargers I've used out in the wild (Free or otherwise)

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    I really like the idea of one motor per wheel, but it needs to in-board. Putting it in place of the normal wheel hub and brakes increases unsprung weight by a lot, which is terrible for both ride and handling.

    The linked article does't mention them. They're great at providing or absorbing big bursts of current, but their energy density is way too low to replace batteries for bulk energy storage.

    I agree and weather proofing would be much better in-board too versus what's hitting the puddles & salt....

    Yeah I know but I feel it's coming and a lot sooner than people seem to dismiss it, its also why it's on the special tariff tax for duty!

    Actually that's a pretty big deal IMO. Certainly not continuous cruise power, but assuming you get that rate for 6 hours a day, that's 45 miles/day range from onboard solar, which is never plug in territory for many daily commutes. You won't always get the sun, but when coupled with 450 miles of battery to buffer against inclement weather and to cover the occasional longer trip... very interesting.
    Silence gives consent.
