Al, if you like the type of music that dude is playing on the guitar, you'll love the new band I started. The two guitarists play stuff like that non-stop in really awesome "guitarmonies".
Have you ever listened to Mastodon? I love that band and some of the stuff they do is similar to that but a little more metal and not as much mega-man. You should check out their album "Leviathan". It's fantastic.

bloody hell, how are you guys surviving this? It is DAMN cold! ... and I missed the worst of it. I don't want to go outside and try my car... one cold vehicle is enough... and I'm loathe to find out how my roomie has treated the place in my absence.
blech. At least it's February now.
actually, I lied... it's not bad outside right now. heck, I didn't mind shovelling for that matter. ... at my parents' place. I don't wanna go back to my place just yet.

Ahhh... thank-you Paras, I can finally see a fallacy in my previous statement! You're right when you say since the thrust isn't coming from the wheels that the forward velocity of the plane won't be affected by the wheels on the treadmill. My confusion though lies in what I thought they were trying to argue:
that a plane can take off without moving forward. I thought the whole reason for putting it on a treadmill was to prove that the forward movement of a plane is not necessary for flight. I thought they were trying to get the plane to take off from a stationary ground position. I think my initial misunderstanding came from my inability to decipher what they were trying to prove. That's why in my earlier post when I watched the video I didn't think the test proved their point so I said: "why does the plane drive forward for quite some distance before it takes off? That's not impressive at all. It honestly doesn't look like they proved shit in that video." But now I think I understand what the question was SUPPOSED to be: will a conveyer belt under the wheels of a plane counteract its forward acceleration? And NOT: will counteracting a plane's forward movement not affect its ability to fly?
I guess sometimes to understand the answer you've got to understand the question.

their thrust is useless because it's being counteracted by a treadmillThis was my point. What makes you think that the treadmill is counteracting anything?
The wheels on the plane are free-spinning. As long as they can spin, there's no impact by the treadmill on the plane's forward velocity.
And that's the point of the question, I think: there's an assumption people have that the treadmill will slow the plane down somehow. But because the plane's forward acceleration has nothing to do with its wheels, it's not going to be slowed down. It takes off as if it's on a normal runway.
I think your confusion (if I'm not misunderstanding you) demonstrates the disconnect there.

Turbines (as al stated) aren't for air flow, they're for thrust, and the air flow comes from the thrust pushing the plane forward through the air (initially on a runway). So if it's a plane with turbines and the turbines aren't propelling it forward (ie: their thrust is useless because it's being counteracted by a treadmill) then what's causing the air flow that's making the pressure differential necessary for lift?
That's my question.
