Submission + - Ask Slashdot: What stands in the way of a truly solar-powered airplane? (gizmag.com) 2

centre21 writes: So I've been reading about solar-powered aircraft all over the Interwebs, as well as solar power in general, but I'm wondering, is it more than just solar cell efficiency that's preventing the creation of a solar-powered airliner? Conspiracy views aside (which may be valid) it seems to me that if I were running an airline the size of United or American, eliminating the need for jet fuel as a cost would be HIGHLY appealing. So I'm asking: what stands in the way of creating true solar-powered airliners?

  • Take a B737 sized aircraft, even if we could convert 100% of sunlight hitting it to electricity, it wouldn't have enough thrust to take off with a normal PAX load.
    In the near future a light aircraft for two people will be viable.
    But the priority should be the electric car, and the fuel cell bus/locomotive. We use a lot more oil in ground/sea transportation than in air transportation.

Once it hits the fan, the only rational choice is to sweep it up, package it, and sell it as fertilizer.
