As an engineer I sat watching the video in excitement envisioning how I could make some of these things work.  I've done countess projects like this that seem hopeless at the start, but actually turn out to be very successful.
  I just can't figure out the infinitely stiff extension poles.  Perhaps 4 wheel mounted electric motors make up for the lack of engine room, but then the battery would have to be some custom Li-Ion configuration sandwiched between the body panels or something.  That's the fun thing about something like this.  Even the technology would have to be invented.  Fun!
