Next thing you'll be telling me is that Gravity is a government conspiracy.
Most airplanes with asymmetric airfoils do not usually remain inverted for long, but can be flown inverted with lots of negative alpha and a lot of power applied (provided the plane has top tank feeds and a pressure fueled carburetor or fuel injection), or through maneuvers where there is always positive G (like a barrel roll).
If you watch a non-aerobatic airplane do a simple aileron roll at an airshow, you'll notice the first thing the pilot does is to pull the nose up a bit into a climb right before executing the roll, because as soon as the roll angle gets past 90 degrees, the vertical component of lift goes to zero, and the plane sinks until the roll passes the 270 degree point. Assuming no elevator input during the roll, of course.
Most every specialized aerobatic airplane ever built (like the Extra 300) has what's called a 'symmetrical airfoil' which in cross section has no difference in its shape whether inverted or right side up. Bernoulli's theorem applies no matter what attitude an airfoil is in - you generate lift (and induced drag) in proportion to AOA.
An asymmetric airfoil (what you find on your 172's, Lears, 737's) is just not nearly as efficient when inverted as a symmetric one is.
In fact, there really is no "inverted" for a symmetric airfoil at all, only the human being carried by it regards such conventions.
All that said, this Moller is indeed a complete charlatan; I've been seeing his bullshit in the backs of magazines for around 25 years, at least.
You can't fly at speeds over 250 knots around cities anyway, so the 350 figure is meaningless for intracity commuting.
If more people move to osx or linux, I guess Symantec and all the others will have to move to writing all these viruses for the new platform, to sustain business.
You don't really think all the malware comes from pimply-faced adolescents, do you?
Or better yet, make a $40 order and pay for it in 40 infected 1 dollar bills!
Most efficient vectoring scheme?

If I were a terrorist and wanted to start off a really good plague with something new, nasty, and specially engineered, I always thought handing out a few infected 20 dollar bills at various interstate highway Burger Kings or MacDonalds would be very effective.
Every car that comes after you becomes a new vector! And heading all over the place!
There was a case like this a few years ago I saw on some 20/20 type show, where a woman, panicked, called 911 and said her car "was accelerating out of control".
Cop shows up while she drives along (she is clearly in control, speeding up and slowing down) puts his car in front of hers, stops her car. Nothing at all wrong with her car, turns out she has a history of mental illness and hysterical behavior.
That's what happened here, bet on it.

Hey come on, Andy Griffith did it that way, so NASA can too!

Would you write an XP driver for the old iRez CapSure pcmcia composite video capture card? It only came with drivers for 98, and has been orphaned!
Who the hell cares if the framerate is lower when your eyes/brain can't see more than 30 fps anyway?
Suckers.
Nice proofreading there, Zonk.

and what do they do, again?
Hey, man, so when can I install Windows 3.1 on my new Sony Vaio that came with XP? Sorta the same deal, isn't it?
There is a usenet posting on this very subject from 1995.
I guess Cape Breton Island isn't as safe as I thought it'd be.

You are aware that many utilities alter their kwh rates during the season? Could explain the bill difference.
As if you don't pay for everyone else's expenses under the U.S. system. Heh.
