First, ducted fans are inefficient compared to rotors. You get a lot more force out of a large diameter and small exit velocity. Its why props are more efficient than turbofans, which are in turn more efficient than turbojets. The ONLY advantage is that the fan is out of the airstream, so high velocities are achievable. It's designed to ferry cargo to troops under fire: with ducted fans you don't have to worry about clonkin' yer rotors on the sides of buildings and the blades can given some protection from small arms. Besides, I doubt a military that sticks jet engines in its tanks cares much for fuel efficiency =P
People seem to believe that if it's integrated, it should be better, but it's not the case. In their benefit, I downloaded and tried WindowsBlinds. It seems to indeed take less RAM and CPU than XP's theme compared (for simple themes).
Hardly surprising: Microsoft licensed (almost) just enough of the old WindowBlinds code to pretty up XP.

It is not a myth although it certainly is pervasive...among physical chemists. Basic thermodynamics is just that: basic. Like all laws of science it makes assumptions that are not always true. Under specific conditions the effect can still be observed once evaporative loss is compensated for; it apparently has even been observed in closed containers.
IIRC, the explanation for the ice-cube-trays-in the-freezer 'anomaly' seems to involve the specific temperatures of the two samples, the insulating sides of the tray (minimising heat loss via conduction), enthalpy of vaporisation and the temperature gradient in the water. But don't quote me.
What appears to be a comprehensive exposition on the matter can be found here here.

It's my considered opinion that many people with keys to the mod-car shouldn't have been allowed off the short bus.
Oooh, just you wait til I mod your comment down. I'll show *you* short bus!
Or play it iteratively. Oh, wait...

Also, WinPatrol with Scotty the Windows Watch Dog. Woof!

Can't, won't or don't?
