Down wind faster than the wind

Why would you leave out the wind?

Not forgetting that this thing called "Wind" is the relative motion between the air and the ground.

The cart is caught between air and ground, just as my cart in the YouTube demonstration is caught between the ruler and the tabletop.
 
I have been telling you that you do not know how you own designs work and it appears from the above, that you are incapable of learning.
To have that confirmed was gratifying. However, to see you make such a lamentable excuse after all your hot air about admitting mistakes, is just the icing on the cake. I could not have insulted you more than you have just done.


This is perhaps your most bizarre post yet. It's as if you think I've somehow admitted I was wrong or contradicted myself.
 
It scares me that there are people like humber in the world making decisions that affect the rest of us. Even when everybody else is pointing out how wrong he is, showing the math, showing the physics, showing the video evidence, he sticks to his original decision.

On a forum it's not so bad and even entertaining at times. But when you find one as a manager (or heaven forbid, a president), their perverted reality impinges on our reality.

It's unfortunate that people are anonymous on this board because what I would really like to do is knock humber off his pedestal and send him back to school or at least insure that he isn't in a position to cause harm.


Humber is no longer answering my posts because I ask too many hard questions

Questions like in the equivalency test:


Why can't humber answer this?

He will, but he also knows that others are trying the same gambit, so he will answer them in one post, when he has gathered enough information.
This applies to the kinematic question also.

If you are interested Dan_0, is scares me that so many seemingly intelligent people can fall for the same mistake.

(1) So, to confirm something Dan_0. You agree that the cart balances as I said? ( I can explain the motion up the treadmill, using your method of forces to the treadmill, if you want) ?

(2) If you do agree that it balances, do you still think that it is traveling at windspeed when on the treadmill?
 
If he would answer that correctly, he automatically has to admit that his thinking was wrong from the start. So he avoids it as much as he can.

If he would answer that according to his stupid view of things, he would make it even more obvious that he has no clue at all.

My guess is that he already knows that he is wrong but doesn't have the balls to admit it. That would pretty well explain his ignorance as well as his avoidance of answering these questions.

Greetings,

Chris

We'll see.
 
Because the treadmill does.

This is one of the truly entertaining bits about this whole problem.

Wind is nothing more then relative motion between air and surface. How people can look at a treadmill and not see relative motion between air and surface is simply astonishing to me.

Air moving from left to right over still road -- road moving from right to left under still air.

Exactly the same thing tsig. Truly the same. To anything in the air or on the treadmill no change. Nada. Zip. Over, said and done.

Cart is at rest relative to the air.

It's plenty easy to explain the performance of the cart climbing an incline. There is plenty of energy available (as has

been show) at the ground/wind interface to cause the cart to climb an incline, accelerate beyond the wind speed, or both. We show all three in our videos. If you hope to get any meaningful answers from the "physicists" that claim this is not possible, I wish you luck. I've yet to find one such physicist that understands the most basic principle of equivalence of inertial frames.


I thought I would never say this but humber is correct.

His description of the cart on the treadmill being in balance is absolutely correct.



Notice the difference there, Spork? Let me spell it out for you. No frames of reference or ground energy are needed to explain your cart remaining on the belt and traveling an incline. This puts the remainder of your ideas in doubt, and explains their rejection by academia.

You respond with this:

I read VERY little of what humber posts. While I've never seen him be right on anything at all (or even close), it stands
to reason that he'd stumble onto something right with the reams he posts here.

Yes, when JB and I go to great pains to get the cart to exactly balance on an inclined treadmill, it is in fact in balance on an inclined treadmill. That seems obvious enough to me.
If we simply place it on our treadmill at max speed and max incline, the cart simply climbs the incline and heads straight off the front of the
treadmill.

Not quite eh? Yes it quite obviously stays on the belt, and moves up it, but my explanation contradicts yours.

You talk a lot of rhetoric about others admitting being wrong, but when it's your turn that is your cowardly and adolescent response.This is why you insult all who question you, including all those 'stupid' professors. They know you are wrong, but you just won't quit.

(1) I think Prof. Whiteman is correct. You are irrational. You claim to have a recording of the phone call, so let's hear it, so that others may judge for themselves. A transcript may suffice.

(2)You said that you had accepted many challenges to your bet, but that they failed because the other party bowed out or otherwise could not agree. I asked you to provide details, but as usual you do not. Let's see those.

(3)You have made claims that some academics do agree. You post links to those who do not, so let's see some for those who do.

This is why I say not only have you contradicted yourself, but that you are afraid to admit your mistakes. I do not want such an apology of course, because I don't actually believe much of what you say.

You'll have to show yourself since I'm not where you are.

Run downwind the same speed as the wind -- do you feel any wind? Though your feet are moving, you are now at rest relative to the air.

Ride a bike downwind the same speed as the wind -- do you feel any wind? Though your feet are spinning, you are now at rest relative to the air.


Drive downwind the same speed as the wind and stick your hand out the window -- do you feel any wind? Though your wheels are spinning, you are now at rest relative to the air.

Do this as many different ways as you wish (including riding on the chassis of a DDWFTTW cart) and the results will be the same -- when going downwind the speed of the wind, you are at rest relative to the air.

Treadmill set at 10mph -- same as going 10mph downwind in a 10mph wind.
