Sustained solar-powered flight, only a matter of time?
Well, today must come to an end, and so must my posts about alternative forms of transportation. But, I couldn't let the day go by without mentioning the last frontier of transportation: flight.
I am sure that you already know that the average jet engine is not really friendly to the environment, and a great deal of work will have to be done before planes are flying on biofuels. Also, if you plan on flying solely on human-power, don't expect to get very far. But, what about solar? Is solar-powered flight just a dream, or could it someday be a reality? Well, check this out before you decide. Yes, I know that this is just a model, and a very small one at that. But, this is a good first step, wouldn't you say? You should really check the thread out, it's well worth your time to read. A thanks goes out to Kert for sharing the link with us.

A solar powered aircraft was, in fact, built and demonstrated a few years ago.

How high and fast to stay perpetually in the sun, over the effective equator (for maximum sunlight)?
10k altitude, stratosphere
1000mph I think. Nuclear powered concorde?
