Anti-Gravity Wheel?

I am here at the University of Sydney where
the mechanical engineering shop has built this incredible piece of apparatus for me.
It is a forty pound, that is nineteen kilogram flywheel on the end of a meter long shaft. Can you imagine trying to hold this out horizontally
with just one hand at this end? It is virtually… it is impossible, ok? No I’m going to let go. You going to be able
to hold this at all? I hope so.
Can you lift it out? Make it horizontal – hold it, hold it, hold
it. Come on. Just try to – I want you to hold
it out horizontal. See if you can. Hold it, hold it!
Ahh, come on! No.
What I’m going to do is I am going to spin this up to a few thousand RPM and then I’m
going to attempt just that, to hold it from one end and have it out horizontally.
Five, four, three, two, one. Boom. I’m going to let go with my left hand. What
you’ll see is that the shaft remains horizontal, see it going around there. It almost looks as though the wheel is weightless.
How does this work? Well instead of pulling the wheel down to the ground as you’d expect,
the weight of the wheel creates a torque which pushes it around in a circle. You may recognise this as gyroscopic precession.
For a more detailed explanation, click the annotation, or the link in the description
to see my video on the topic. Here I want to try something more extreme.
I’m going to try to lift it over my head with one hand while it’s spinning. Wish me luck. But before I make the attempt, Rod wisely
suggests that I first check if I can lift the wheel above my head without it spinning. OK, let’s prove that I could lift it, just
this end, without it spinning. Here we go. agggh
I mean it’s just kind of awkward with the hand.
Careful! Ah, che
Careful! Ha
Oooohhh Just barely. Oh goodness, do you even lift?
Clearly I do not. Undaunted by my lack of strength, I’m going
for it, but I want to make sure the wheel is spinning as fast as possible to give me
the best chance of success. Give it ten more seconds.
Ten, nine, eight, seven, six, five, four, three, two, one. Pull!
Go. That was perfect.
Now I’m going to release my left hand and holding only with my right hand at the end
of the shaft, I’ll try to lift it up over my head. This is a forty pound, nineteen kilogram
flywheel. Ready?
Here we go: three, two, one. Beautiful! Let’s go again in three, two, one. Nice!
Smooth. Three, two, one. It feels incredibly, incredibly light as I
do that. When you said it felt incredibly light,
yeah you mean when you’re lifting it feels light?
Yeah. It shouldn’t!
I know. Hahahaha
Honestly, I have lifted it up with one hand when it’s not spinning.
Yeah. And it feels really hard to lift it up, like
it’s a big effort. Yeah.
But with this, when it’s spinning it honestly felt like it was just…
wanting to go up by itself. Yes.
It felt like I was not struggling like I was not putting in the amount of force that you’d
think to lift that kind of weight. I bet if you let it go, it’d crash down to
the ground. It’s not weightless! We can’t do that though. We can’t do that
part of the experiment. What we could maybe do is I could stand on a scale and we could
see what the weight of me plus that apparatus does, while I’m lifting it up over my head,
see if I get lighter in essence. You can see that just my weight is about 72
kilograms. Now when I pick up the flywheel it goes up to about 91 kilograms, which makes
sense because the flywheel itself is about 19 kilos, that’s about 42 pounds. Now we’re going to spin it up and I want you
to make a prediction. As I’m lifting it over my head, do you think the scale reading will
be more, less than, or equal to 91 kilograms. What do you think? You can make your prediction by clicking on
one of the on-screen annotations or if you’re on mobile you can click a link in the description. Five, four, three, two, one.

  1. Imagine a vehicle, round shape, that has lots of this thing arount it in a shell instead of wheels, that is called Flying Saucer!! Damn! Aliens exist!

  2. It simply uses "magnus effect", it doesn't defy gravity, just has another force providing normal reaction to it in mid air letting it partially balance gravity

  3. If you spun up two wheels, one on each end of a rod, barbell style, so that the wheels were spinning in opposite directions to cancel out the procession, would it cancel out the effect and simply be a very dangerous spinning barbell?

  4. I believe this trick works like quantum physics. Like light, the weight requires an observer, or in this case a strongman.

    It is lighter, the quantum mass, when someone is lifting it.

    The usual mass when someone is weighing it.

    I believe it is in two states, or two masses, at the same time.

  5. Would it work the same way if u added two flywheels that both spun a different way? And can u do a video of it if its possible?

  6. Los masones de mierda o poderes fácticos, luchan para que la energía libre Nunca sea de usó común para la humanidad

  7. I think it isn't anti gravity. Because you moving forward. You just only throw the energy. Asia people know this very well…

  8. Pity you chose not to mention of Professor Eric Laithwaite, former Professor of Heavy Electrical Engineering at Imperial College London, who first demonstrated this experiment, and who you've obviously copied it off. Your experiment trying to weigh yourself is flawed, because you will be bouncing up and down a bit on the scales which will throw the result.

  9. Porque os engenheiros não enchem os interiores dos caminhões de cargas com algumas rodas como essas e assim poderiam diminuir os excesso de peso que a gravidade exerce sobre a carga e no final isso resultaria em baixo consumo de combustível fóssil!!!

  10. This is super simple and no, it’s not how flying saucers would fly if they existed.

    Centrifugal force. When the disc is spinning really fast, they centrifugal force is almost as strong as gravity which explains why our skinny host can suddenly hold the stick with the spinning disc at one end.

    The trick ONLY works when the spinning disc is held vertically because gravity pulls towards the mass generating it while the centrifugal force pulls equally in all directions away from the axis of the spinning disc. If he had held the stick with the disc straight over his head, the trick would fail as the centrifugal force was pulling to the sides instead of downwards.

    A flying saucer would therefore need to be vertical instead of horizontal and even then, the centrifugal force would only help carry the discs, not make them or anything else weightless. And that doesn’t even address the energy needed to spin such discs fast enough to ALMOST nullify their own weight.

    Just think about it.

    Elementary, dear Watson.

  11. The answer to anti-gravity is right in front of you. Why don't you see it? The answer is still invisible as a knowledge which already has been disseminated, but the answer is always in front of you. We all live under it's rule every day. If you make a million guesses, what are the chances that one, or twenty are correct? Now focus on those possibles. Then narrow down the amount of tests of the ones you choose. Of what amount of those are false leads, and wasted on the true, and correct answer to this difficult problem? I believe those who come close to the answer are stifled and stopped from their proving grounds, and this is the battle we are constantly forced away from with distracting physics that only flicker its real power.

  12. What happens if you accidentally come into contact with that spinning disc? How fast is it going? Is it like touching the rough surface of a running angle grinder with your finger?

  13. I know why the gyro is easier to lift. Individually, the angular and linear momentum are NOT conserved separately. This is a mistake in physics. The SUM of angular and linear momentum IS conserved, however, AND this correction to (or clarification of) Newton's Rule by Laithwaite allows for the conversion of one into the other.
    In your experiment, just as in Laithwaite's experiment, the gyro was easier to lift while it was spinning, even though the weight didn't change. If your scale had a platform which could rotate as you stand on it, you would find that the gyro naturally wants to precess and your whole body would precess with it. This represents the almost complete conversion of the downward component of its initial fall into MORE angular momentum. When you lift it, the gyro rotor dips even more downward causing an increase in the processional angular momentum. Thus, the SUM of the two types of momentum (linear and angular) is conserved, even though one got smaller and the other got larger.
    The reason it is easy to lift is that the upward momentum you give it with your hand is mostly converted into angular momentum. This causes the force of lifting to virtually disappear. It is a real effect. Any upward momentum you give it is going to show up in downward momentum and register as a force on the scale, or a weight increase. Physics is not perfect. It contains a few glaring mistakes like this one. Keep using your brain. It's working fine.

  14. (from the OverUnity Forum)

    Had Laithwaite sped up his ball and stick wheel to the point where

    a balancing weight was no longer needed, he would have observed the following:

    The top weights bend towards the tower.

    The bottom weights bend away from the tower.

    This bending arises from the back spin giving a differential travel speed to

    the top and bottom line of weights, cf. the effect of back spin on a cricket ball.

    Thus the top weights rotate around the tower at a lower speed than the bottom weights.

    This induces a couple, or moment to use the structural engineering term more

    familiar to me, acting on the gyro.

    This couple is the pair of centrifugal and centripetal forces holding up the

    gyro as it orbits the tower.

    What about centrifugal force? Surely this should pull the gyro away from

    the tower since the end of its axle is simply resting on a shallow depression on

    the top of the tower.

    Looking down from the top of the gyro the it will be seen that the top line of weights

    is convex towards the the tower whereas the bottom line is concave.

    Thus there are two centres of curvature for the path of the weights on either side of

    the gyro orbit.

    Far from being no centrifugal force there are two.

    These act in opposite directions and virtually cancel each other out.

  15. So where does the energy lifting the gyro against Newtonian Gravity (NG)

    come from?

    It has to come from the Ersatz Gravity (EG) field. The G force experienced

    by fighter pilots and exercise fanatics in 2001 space stations.

    The moment that the Prof's stick and ball weights applies to the heavy gyro

    unbalances the opposing centrifugal forces and generates [b]EG[/b] energy.

    One centre of curvature moves in towards the gyro, the other moves out.

    The energy generated is the difference between the two.

    Remember, EG obeys a square law whereas NG is linear.

    The beauty is the evidence is unarguable. The experiment has been done.

    Anyone can easily repeat it for themselves. He raises 50 pounds in the air

    with ease. Energy is obviously being supplied from
    somewhere other than
    the gyro because the speed of the gyro doesn't change.
    If he'd been tall enough he could have gone on lifting the gyro

    until he reached stationary orbit providing he kept his feet firmly on the

    ground so as to maintain ground reaction.

    Frankly, I would have more sympathy with someone who claimed the

    demonstration was fraudulent than someone who tried to explain
    this unmistakable gain in NG potential energy. It's a bit like

    Desertphile's attitude to Al Setalokin's WhipMag. He recognised

    it was clearly generating free energy so he claimed it had to be

    a trick.

    Developing this phenomena to obtain energy on a continuous basis

    should not be difficult once the psychological block of cognitive

    dissonance is removed. Even a colonial university should be able
    to manage it. 😉

    If I had oil shares (which unfortunately I don't, 😒 ) I'd sell them now.

  16. I have come up with an idea. Put 300Kg of weight on a barbell and spin them in opposite direction and place the barbell on the something so the weights do not touch the ground. Then lift it and turn slowly and you win a gold medal in heavy-weight weight lifting competition in the next Olympic.

  17. Here is an image of Professor Laithwaite pumping up a heavy gyro

    with 3rd derivative Precession Kinetic Energy (PKE).

    Here is the video from which that image was taken:

    How do we harvest that PKE?

    We transfer support from the end of the shaft to the centre of the gyro disk.

    Stripped of PKE support the disc will give up its 2nd derivative

    Newtonian Gravity,,(NG), potential energy by falling to the floor.

    The cycle is then repeated.

    The energy produced by each repeat is the difference between the

    Ersatz Gravity (EG) energy provided by the Prof. in lifting the

    gyro and the greater energy given up by the gyro falling under NG.

  18. Professor Eric Laithwaite. MagLev train inventor. Rejected by the Royal Society on his gyro theory. In his 1974 lectures, Laithwaite suggested that Newton's laws of motion could not account for the behaviour of gyroscopes and Laithwaite suggested that they could be used as a means of reactionless propulsion[3]. The members of the Royal Institution rejected his ideas and his lectures were not published at the time, a first for the Royal Institution.

  19. Now spin one 80 lb weight same way while on top of it is another 80 lb weight spinning OPPOSITE way. WARNING: TIE A 10 FOOT ROPE TO YOUR WASTE AND FASTENED TO THE GROUND BEFORE…….ATTEMPTING THIS EXPERIMENT !!!!!!!!!! Otherwise: have a nice flight 😆 (helicopter blades work in similar way but by throwing this rotating mass over you, and AWAY from you outward = lift. The tail rotor acts like your stationary body.

  20. This guy’s countdowns couldn’t be any more annoying. I can imagine him counting down everything in his life like he’s eternally 7.

  21. my real question with this is at what speed does the wheel lavitate on its own, if it's wheight becomes lesser and lesser the faster it goes then i think at a certain speed equilibrum is reached and beyond that speed levitation can be acheived
