The shortcomings of the internet, when it is obvious that someone is making a joke, at someone else's expense smileys should not be required.

Of course my mistake was in being overly polite to 3bodyproblem to start with. I was trying to give him the benefit of the doubt, unfortunately for him his later posts have erased all doubt.
You're making a conclusion before you even consider any of the steps. Start at the beginning, not the end.
The energy source is the wind. Are you familiar with how the energy available from the wind is calculated?

Are you remembering to hop?
Perhaps you need someone to hold you down against the belt. Or the wife can stand in front of the treadmill and push you backward with a homemade plastic spork. That'll surely make you hover (and balance).

Blog here
and here
and here
and here again
and here's another
and this one
oh and once again
here too
If this isn't you blogging, brother this is some conspiracy.

On a trip to Hong Kong, I saw baseball caps that had been fitted with a small propeller, to keep the wearer cool! I wonder if you wore one of those and your roller skates, you could hover on the treadmill?
You really have a lot of homework to do before declaring anything to be nonsense.
In that case, maybe you should carry spork on your back while you wear the cap with the propeller and the skates on the treadmill. It would make a great video!

No problem, I actually can appreciate the new blood to this argument. They are wrong of course but I was getting more than just a little tired of humber.
The first one isn't me. The second one isn't ANYONE. The third one is the YouTube video we posted as part of the Mythbusters video challenge. In any event, it's pretty darn clear you don't know what a blog is, because I've NEVER done one.

I'm afraid that resonance between the little propeller on my cap coupled to the treadmill belt and my imperfect skate wheels will result in a calamity that would dwarf the Narrows bridge incident! Oh the hilarity!
You can Google to find the differences between treadmill exercise and real running. However, the treadmill's motion is not responsible for your expenditure of energy. It provides a reactive force to your muscles. In fact, you don't want the motor to do your exercise for you.
The body absorbs some of the KE generate while running, or stores it in ligaments, to be later returned. When walking, the leg is raised against gravity, and returns much as a pendulum. We need a make a bit of 'gap' to ground, so there is a lateral waddle to our gait. The belt simply moves back to accommodate those and other actions of ambulation, and our balance mechanism. Your are also your own dummy load, so to speak.
You can see that running is no more than a simple repetitive cycle, and if that is once possible, the length of the belt makes no difference.
Quite different ideas there.
No, the power will fall to almost zero.
I think that the amount of energy consumed by the motor by the addition of the cart is negligible.
Talk of resonance is overwrought.
The belt is passing under the wheels at exactly the rate that the wheels are rotating in the opposite direction. That is the the equivalent of a fixed point w.r.t the ground. (they subtract to produce zero w.r.t the ground).
All motion is therefore w.r.t the ground. That motion is nothing more than a slight imbalance in that subtraction. In principle, the cart cannot move.

Hints of domestic violence now. Science, heh?
But at least your mention of the Narrows Bridge shows that you can at least understand how the energy delivered to a resonant object is multiplied. Note, energy itself is not multiplied, it is the amount delivered to something from something else, that is multiplied. On the treadmill, all of the energy comes from the electric motor. It delivers only so much to the cart but at resonance, it can deliver more, enabling the cart to speed up. Going down wind, there is no reason to think such resonance can be achieved. In fact, there is no evidence at all of a cert moving down wind faster than the wind, only a cart moving down wind.
You're wrongness is truly spectacular.
A) there is only one of me. To my knowledge no one else in the history of the planet has ever offered these carts at any price.
B) I offered them at $40. So you were only off by 100%
C) I'm willing to bet you an amount of your choosing that I understand thrust better than you - certainly better than the nonsense you've spewed here about thrust being the rate of change of mass!
Yup. 671 posts, and you haven't found a blog yet. But keep telling your lies.
