Good reply. Don't be greedy, just take one, and see if you can deal with it on your own.
I can find many pages, BTW. You are flat out wrong, your treadmill is a joke.

So I guess I just hallucinated all those you-tube videos where the cart moved against the belt, faster than the belt.

So here's mender forum jumping again. Great retort to schroder, btw. And the lack of dust and position of driver made me wonder how humber could make such a speculation also. So, as did you apparently, I noticed the time frames of his posts. What makes humber run? You have to admit he's right about the enigma bit.
Some really high wire traipses along the borderline today though, so do let’s continue on with the humorous aspects long in play here and not again take things too seriously. I want more anemometer savvy bunnies! And how about some good analogies from both sides on making their opponents argument? Humber's from spork’s perspective, and vice-versa? Motivations, overall viewpoint? But realistic, not parody which both sides employ to an extreme level. The obvious ‘turd on the floor, that all shall ignore,’ is that none involved in this 90 page cyber-anthropological tutorial would have spent even one page of replies on an idiot. Full of sound and fury yet signifying.... nothing???
It moves just faster than the belt? So what?
Go to your supermarket checkout, and with but a small push from your hand, make a can or jar do the most miraculous of things. Move faster than the belt!
Post is on you-tube. Stun and amaze the Crowned Heads of Europe!
If the wheels are in good contact with the belt, then they must move at the same speed as the belt. The propeller is directly geared to the wheel, so it cannot turn any faster than the wheel. Therefore, when it does move forward, it must be sliding to some degree. There are several mechanisms at work.
How can the cart make linear progress from a standstill? The wheels either slip, or turn at exactly beltspeed.
The way it responds to the stimulus of the fork, is evidence of a marginally stable system.
Hallucinations, or simply poor perception?
Now, who is not "grokking". A photo like that can be what you want it to be.
Hollywood defies physics as stock in trade.
The photo has been rotated to make the angle steeper. It is a strawman introduced to cover up lack of basic knowledge, that is all.

To see the whole list, just concatenate all 2000 (or however many it is now) of Humber's posts. There is of course a sentence here and a paragraph there that are right (probably by accident), but I doubt that it would amount to more than two or three percent of the total. Of course something like 30% to 40% of that huge body of text is so incoherent that it's possible to figure out what Humber was trying to say, but I think we can count that as wrong.
Bluff, and hopefully, unchallenged. Pick one, and go with it.
Alternatively, you can tell me how the wheel can spin faster than the belt
Within the bounds of simplification and generalization, what I write is 100% correct, with the occasional bit you understand.

So, imagine a cart with no propeller, just a flat plate. Put it on the treadmill, and use your hand to control its speed. The belt moves, and the wheels, which have good traction, turn at some speed that is maybe the same as beltspeed (in which case the cart stays still relative to the floor), or slower than beltspeed (in which case the cart backs up relative to the floor), or faster than beltspeed (in which case the cart moves forward relative to the floor). Any problem with that?
Now, let go of the cart, and use a fan to blow on the back of the plate. Provided the fan is blowing hard enough, the cart can stay still or even move forward relative to the floor, while its wheels roll on the belt with good traction, and it doesn't matter what the wheel contact patches are doing. Any problem with that? No hovering, hopping, or slipping required.
(That's the simple stuff that even you should be able to understand. The part that I don't expect you to be able to comprehend is that the fan can be on the cart, facing the other direction, powered by the wheels, and produce the same effect.)

Beats me. You're the one that said "motion is impossible".
For the cart, substitute the propeller for your hand.
The wheels have to slip for the cart to move at other than beltspeed? How do the wheels know that they are moving forward faster than the belt is moving backward and that they have to slide instead of roll? More of that magical ground influence? You've outdone yourself with this one Humber. Even more ridiculous than the canoe making a bow wave while drifting at the speed of the current. You really don't understand how wheels work.
Poor perception. By you.

Me too - 95 to be exact. And every one of them dedicated to your complete confusion about basic physics.
Yes, and the joke is on you.

He is, but he won't notice until the meth wears off.
I am reluctant to do so. The photo of a car on a hill suggests that "where you come from", plants do not grow in a manner that best benefits them. I think the photo has been rotated, and the man in the driver's seat is the photographer's boyfriend.
Of course. The force needed to restrain the cart is only the result of friction.
That between the belt and the wheel bearings. You can get an idea of the forces required, by buying a $1 child's toy, and running a sheet of paper beneath the wheels It is a trivial level of force.
That is because you have independently moving air driving the propeller.
Please move so that you can shoot your other foot.
With a fan, the wheel is driven by the prop, so the force develops behind the axle, moving the cart forward. However, for this reason (amongst others) the belt cannot force the same condition upon the wheel.
Also, because of the synchronized motion of wheel and belt, and in concert with the internal balance mechanism, it can't force it backwards either.
Really. Do you have three feet?
Your expectations are delusions.
(1) The so-called "wind" is a result of the cart's motion with the belt, otherwise there is still air.
(2) The rim of the cart's wheels, move at the same velocity as the belt.
(3) Because of that, there can be no motion relative to the belt.
(4) That means there is no "wind"

Small fry. Back in the water.
A barometer not only of your intelligence, but wit.
And your replies evidence of no knowledge what so ever. If you can't say "frames of reference" you are stumped.
If you try, you know I will thrash you.
The repetition familiar of the schoolyard. You need to go back there, for more reasons than to learn some science.
It means Fredriks, that a treadmill from Walmart only loses functionality when in Spork's hands.
