Any chance that you can give us a summary so that we don't have to waste the better part of 2 hours watching a video full of obvious errors that you missed or ignored?

Don't bother,  it's about whether the tyres on Elon Musk's Tesla would have exploded in space.

Please explain your problem?

The pressure at sea level is near enough to 14.7 psi and the pressure in the "infinite vacuum of space" is near enough to 0 psi.
Even I can work out that the difference is 14.7 psi.

Your "7th Day Truth Seeker," gives this comment:
Quote
760.0 torr = atmospheric pressure
10^-17 torr = 0.00000000000000001 torr  = vacuum of "outer space"
Now to anyone that knows anything about numbers, 0.00000000000000001 torr is so close to zero as makes no difference!

So put a normally inflated car tyre into a vacuum and it experiences an extra 14.7 psi of pressure difference.
Now I usually inflate the tyres on my Toyota 4WD to about 35 psi, but the maximum rated pressure for those tyres is 64 psi.

So putting my tyres into a vacuum would be equivalent to inflating them at 49.7 psi, still well under the allowed 64 psi.

Now, who knows what the initial inflation pressure of Elon Musk's red Tesla was? It may have been well under the normal pressure for driving on a road.
On soft sand (say over "Big Red") I have run with tyres as low as 12 psi. An extra 14.7 psi would still not have brought the pressure up to normal road pressure!

In that video, we have no information as to the initial pressure in that football, so it means nothing. Other than a totally deceptive attempt to prove Wolfie6020 wrong!

The whole of that video is utter crap!
If you disagree, post your own justification of the points raised because there's no way I'm going to wade through 1 hour 45 min from someone who has no understanding of pressure or temperature.

Several points.

Inflating tire pressure an additional 14.7 psi is not equivalent to subjecting the tire to the vacuum of space.

It has been proven vacuum can be applied to lift a tremendous amount of weight, leaving open the question as to how an atmosphere is maintained without being enclosed.

Rail cars subjected to vacuum collapse quite easily.

Totally incorrect! Please provide evidence of your claim.

No, a vacuum can lift nothing.
So called "Vacuum Lifters" simply rely on the pressure difference between the atmospheric pressure and the lower pressure of the near vacuum.
A "Vacuum Lifter" will not work at all in a vacuum. This example is just small suction caps, but they work on the same principle.

No question at all. It's about time you realised that a vacuum does not suck,
the atmospheric pressure simply "fades out" till at 100 km altitude it's density is only about 1/2,200,000 th that at sea level.
Finally the density becomes so low that individual atoms move as tiny projectiles and since virtually all travel at far less than "escape velocity" the atmosphere is retained by earth.

Quote from: totallackey

That is totally different. A thin walled tank can withstand far more when the internal is greater than the external pressure than vice-versa.

For example a PET soda bottle can easily be collapsed by suction as in:
#
plastic bottles and vacuum, marksmall82
But can withstand considerable internal pressure. See here:

PET Bottle Burst Tests, Air Command Rockets
The bottle often busts at over 175 psi.

Yeah, those containers are subject to normal atmospheric pressure.

Kindly demonstrate in even a man-made vacuum.

A vacuum that can lift over 30000 lbs is definitely a force.

Kindly reproduce any kind of layering of air, gradually resolving to the vacuum conditions of space.

No, it is the atmospheric pressure "that can lift over 30000 lbs is definitely a force." A vacuum on its own can lift nothing - it is always the difference in pressures that creates the force.
You find an example of that "vacuum lifter" lifting 30000 lbs when it is in even a man-made a "vacuum" chamber.

Why should I bother? Your original video did not show car tires in a vacuum, man-made or otherwise - only a football, inflated with an unknown pressure before it started.

If you are so ignorant of way pressure falls with altitude, it's hardly my job to educate you.

But why are aircraft pressurised at even 30,000 ft?
          Simply because even at 30,000 ft the atmospheric pressure has fallen to about 4.37 psi.
Why do balloons rarely get much above 120,000 ft?
          Simply because at 120,000 ft the atmospheric pressure has fallen to about 0.62 psi and the air is not dense enough to support the weight of the balloon and payload.

The same old excuse...

Cannot reproduce what is claimed.

A pressurized container inside a vacuum will explode.

That was demonstrated by the video.

Asking for a vacuum to work inside a vacuum?

WTF sense does that make?

I am going to need to wait to look at the videos you claim demonstrate humans training in a vacuum.

The claim that it is the external atmosphere on a vacuum lifter that is responsible for the lifting power is just absolutely laughable.

You have to repeat it as often as you are willing to repeat the atmoplane exerts no force upon everything on the surface of the Earth.

Effectively, what you want to state is this: A vacuum lifter exerts no force. It is the atmoplane of the Earth at 14.7 psi, pressing a 10 foot by 3 foot mechanism down hard enough in order for a 30000 lb pipe to be lifted against a force causing it to accelerate back toward the center of the Earth at 9.8 m/s

Okay, you need help with this.  That's fine.

35 psi is 2.4 atm.  The volume of a typical car tire is 10 L.  The temperature of the air could be 290 K, although changing this isn't going to have a significant effect on the answer.  The Ideal Gas Constant is 0.082057 L atm mol-1K-1.

Number of moles = Pressure x Volume/ Ideal Gas Constant x Temperature or n=PV/RT.

Plug in the numbers and we get just over 1 mole in the tire.  A mole of dry air weighs approximately 29 grams, which is almost an ounce.

Even if you squeeze 2 moles in, that would be 2 ounces of air.

So again, why do you think a rail car with an internal vacuum getting crushed by miles of atmosphere above it is remotely comparable to a tire with an ounce or two of air holding it in with an external vacuum?  Do you see that they are different now?

And you need help understanding the following.

Please mount an empty tire on a rim.

The you fill the tire to the recommended pressure.

And then understand that it is still 35 psi that is important.

Without a countering 14.7 psi on the outside, that tire would explode.

The burst pressure of a typical tire is around 200 psi.  Do you really believe that the 14.7 psi pushing in is the only thing keeping the 35 psi pushing out from causing the tire to explode?   Here is a hint: the tire is more than capable of handling 35 psi without bursting, even in a vacuum.

Does your body create a vacuum between itself and the pipe?  That would be pretty amazing...

What really happens is the 10ft x 3ft lifter creates a seal with the pipe and then pumps all the air out.  The 14.7 psi of atmospheric pressure is now pushing on the pipe in every direction but down.  The lateral pressures cancel each other leaving 14.7 psi of upward pressure.  That atmospheric pressure holds the pipe to the lifter. 

The atmosphere doesn't do any lifting, by the way, it just holds the object to the lifter, which can then be manipulated mechanically to move up sideways and back down.  The vacuum seal is just taking the place of pincers, a bucket, or some other mechanical means of grabbing the object that is to be lifted.  The atmospheric pressure doesn't lift the pipe, it just keeps it from falling.

And pressurized containers placed inside  a vacuum would, consequently, explode.

And they do.
Only when the pressurized container is not strong enough to resist the pressure.
Any pressurized container that collapses when a vacuum is introduced to the inside will explode when pressurized and placed inside a vacuum.
First of all, you cannot introduce a vacuum to a container.  You evacuate the air inside the container to draw a vacuum.

Secondly, containers, especially flimsy ones, are usually better at containing higher internal pressure than resisting higher external pressure.  Why do you think that drinks bottles and cans are so easy to crush but don't generally explode when you shake them?



A vacuum that can lift over 30000 lbs is definitely a force.
A vacuum is, by definition, nothing.  How can nothing be or exert a force?  If anything, it's a vacuum's inability to resist forces that is significant.
Well, if a vacuum is nothing then it must nothing that lifts the steel piping in the OP video...

A PENGUIN MIRACLE!!!
Nope. 

The claim that it is the external atmosphere on a vacuum lifter that is responsible for the lifting power is just absolutely laughable.
Pressure is defined as a force exerted over an area.  A vacuum is, by definition a low or zero pressure.  I fail to see how zero force exerted over an area  is going to lift anything.

How do you exert a force over an area without punching a hole in the area? And a force applied will not lift anything. It will just accelerate what it is applied to. So I agree you cannot see it.
