But I think this design is a little to gimmicky.  390lbs = useful load is me and a child.  And where are we seriously going to = go within 200miles?  A serious effort would drop the cost, = complexity, weight, drag and airflow disruption of eight of those motors = to produce a decent electric plane.  Then I suspect you could get = 3-500 miles with a 450lb load (Me, my girl, and her bikini.)  (On = second thought, no need to make allowances for the bikini.)

I agree; the future is closer than we tend to think. :-) We use things every day that were science fantasy (not just fiction) when I was in high school. I'm pretty confident that by the time my RV-7 rotary flies, I'll be able to put an affordable electric motor & batteries on at least an ultralite style a/c as an 'after supper' toy.
