Thanks for the post. Up to now I've dismissed any talk of an electric plane as pie in the sky, but reading the link I now see that an EP makes good sense when used as a commuter. I wonder if the hybrid strategy is similar to the Volt in charge sustaining mode, i.e., battery used when most power needed and generator power used for steady state cruise power. I wonder if it would be possible to regen in an airplane?

Regen should be possible, by reversing electric motors that generate thrust. It'll only apply when you need to slow the airplane on descent and landing, naturally.

And here is a flying example that proves the concept

http://equatoraircraft.com/index.html

A 2 seat light aircraft which has basically the same power system.
I think it's a big premature to say it proves anything... it hasn't flown yet. I actually really like the design, and they are supposedly getting close to a first flight (though they've been saying that for a few years), but it's a pretty complex system for a small aircraft and I have a hard time believing it will ever be commercially viable.
