I am putting my own money into my own (possibly) miraculous endeavour. I'll see how I go. Unlike some commenters, I am also following what's happening with a spreadsheet of calcs to guestimate what people are doing in terms of range, payload, hover power, etc because it helps in my quest to establish the envelope of the possible. From my work, I don't think you need huge batteries to be useful - certainly a fraction of what a Telsa is carrying about. I think 40kWh tops for something that is useful. Obviously not for the Über model of carting five people about but as a single-seater for useful short cross-country work.
