Almost didnt see what you wrote as it was embedded in my quote.  =]

Well if you look at the cam angle where I see the arms kinda fly leftward as the fall and extend out, this doesnt look like a tight noogie. ;]   And I see where you are seeing the arms that I claim being blown at the bottom just drop to a hang after being what you see as tight. I think that we see that drop due to the arm in front of it finally blocking the wind.

Ive really looked at this pretty good.  When we see these machines in motion, sure they look as if, wow, there it is folks, and everything seems to make sense.  But just as in mylows vid, and he admitted doing wrong in the end, look how long it took to see the fishing lines and the motor set up on the couch, and him stepping over the lines that were discovered while filming.

I think there may be a ceiling fan also. cant say cant see.  I said above a couple times that I may be wrong.  And you all can make up your own minds.  =]

Oops,  I see my post got lost in your quote but for some odd reason I don't seem to be able to 'modify' my post now.  Thanks for catching it.  It's really hard to say on this.  I don't think a ceiling fan would do anything though.  It seems the only direction an air flow would help would be from the side the movie taker walked around and near the bottom to be of any assistance in turning it.  I've got enough of a start on a build similar that when it warms up a bit I'll get into my shop and try this as I don't think it will take more than an hour or two to finish a build I started years ago and turn it into this style setup.  I anticipate I can put it together without even buying anything additional.

Very cool E2.  Look forward to seeing what you have come up with.
Back when I started with the gravity wheels, my first was the rolling marbles, then a couple like we see here. My last was the sliding rods, where I spent a lot of time on.
But who knows, Im definitely not Einstein. =]
good luck.

Here's an excerpt of Mikhail Dmitriyev's video focusing on the important part of it:  http://www.youtube.com/watch?v=ENrMwPNt9Cc&feature=player_embedded#

Thermodynamics never takes into account the energy put in to build a machine. The energy balance in thermodynamics is always done from the moment there is a machine available on. In this case the work of the machine starts from standstill. At that standstill the machine has certain gravitational potential energy, as a, say, ball has when sitting on a table with respect to the floor. In the case of a ball on a table, once it's let go towards the floor it can never recover the initial potential energy due to losses and never reaches the height of the table on its own. In this case the construction more than recovers the initially put in energy thus producing excess energy ("energy out of nothing", as it were).

What we see in the video is that when the lever with weight (the pendulum), attached to a one-way clutch bearing reaches the 12 o'clock position the second time it is already in a retracted state. The problem now is, as in every case of a magnetic or gravity motor, to construct a proper negative feedback mechanism which would use the obtained excess energy to restore the initial state of the lever (the state the lever had at the beginning of the experiment).

Probably using some kind of low-friction ramp would be the solutions here too (aside from the brute force approach Dmitriyev applies by using a swastika-like retractor driven by an externally powered motor; that solution isn't acceptable for convincing society let alone that we already have Paul Sprain's solution). I've tried using a magnet, positioned right where the restoration of lever arm position should occur (12 o'clock) but now one needs to have the one-way clutch to suddenly turn into two-way clutch and then revert back to one-way clutch.  Otherwise, the attraction continues and the lever overshoots the needed position. As is easily understood, converting a one-way clutch into two-way and back is a mechanical problem of exactly the same type we've had in all these cases whereby rotational energy has to be converted into translational.

So, in this case, as in each one of the cases studied so far, we have to focus on ways to accomplish this negative feedback as frictionless as possible. Also, one doesn't need to add more and more weights or to come up with another 2000 ideas having the same problem. One working solution is enough.

So, yes, there are attempts to fake a gravity machine but the truth is, in principle, it is possible to build one, as this and many other experiments prove.

Groan.

Draw the thing out on a piece of paper and then do a moment-arm analysis. You will see that the wheel is actually always IN BALANCE. Gravity cannot be doing anything here. The device is likely powered by air flow in the environment, and it doesn't take much of that. There is considerable "flywheel effect", that is, energy is stored in the rotational inertia of the device, so standing in front of the airflow for a few moments won't hurt much. Plus, considering the design of the device, the air could be hitting it from any direction within the plane of the wheel, and it would turn. Top, bottom, side, it matters not. A ceiling fan could indeed be making it turn.

I can hear plenty of noise in the background that could indeed indicate fans or a vacuum cleaner blowing on the thing. Note that the device is a product of a "design studio"... meaning artists.

Nice puppy dog, though.
