Solar Plane Completes 24-Hour Flight 88
asukasoryu writes "An experimental solar-powered plane landed safely Thursday after completing its first 24-hour test flight, proving that the aircraft can collect enough energy from the sun during the day to stay aloft all night. The record feat completes seven years of planning and brings the Swiss-led project one step closer to its goal of circling the globe using only energy from the sun. The team will now set its sights on an Atlantic crossing, before attempting a round-the-world flight in 2013." We ran a story about the flight's departure yesterday.

Solar powered flight is evolving just like any technology, and it's currently in its infancy. It may or may not ever prove to be practical, but abandoning it just because an experimental craft has shortcomings we don't think a fully mature product should have would be silly.

you're still not talking anything remotely practical for commercial use.
If such a plane can be made to carry even small amounts of cargo across the earth - slowly, but faster than terrestrial speeds - and it's operating costs are negligible, wouldn't that have a variety of commercial applications?
An unmanned variant might someday even has some military and civilian uses
Contradicts first statement.
it's never going to replace our chemically powered, high speed transportation aircraft.
Possibly true, but irrelevant.

I'm guessing all those times I spent at the end of a fiscal quarter or a fiscal year hoping I had enough budget to buy my spares and consumables were figments of my imagination. The same goes for the gradual accumulation of ships at the piers towards the end of a quarter, after all they didn't have a quarterly fuel budget... (And this was at the height of the Cold War!)
Or, IOW, bovine exhaust. The military does care about the costs of fuel and operations as they don't have a blank check.
The military also cares deeply about endurance and cycle time - because the shorter they are, the more units you need to maintain coverage. All else being equal (and taking budget into account) they'll chose the system with maximum endurance and minimum cycle time consistent with minimal life cycle costs.
