David Hamel Generator.

[Steven Dufresne]

I also built a Hamel 3 cone device a few years ago after reading about it on several sites.  Mine did exactly what Anand's did in his video. I must have made a hundred adjustments but it would always stop.

@Vince,
Nice work. Do you mean it spun or that it wobbled or both? Mine wobbled for sure. I don't recall any spinning. Did you ever try with it enclosed in a metal container? David always said that the air motion around the cones is important. Without the enclosure you wouldn't have the air movement. Also, if there's ionization (my theory, though David's mentioned of the colored glow supports it) then that might be needed to build up before it would become self-sustaining (again, my theory.)

The upper cup was sidewards under the force of the magnet above it. The smaller magnet did not show that. So the alignment was right but the force of the field couldn't keep the 3 in line.  Lowering the magnets makes it pend in one direction always. A wobble would be a back and forth motion of the top magnet, but the field in the middle would prevent it crossing the centre so that the only way is for it to spin, Or am I wrong? Naudin's replication-model shows a spin with the wobble.

@Anand,
There may well be spin, but according to what David Hamel told me, it's the wobble that we're after. I don't recall mine spinning.

So you have seen a Hamel device working perpetually, or just for some time?

I've never seen one working perpetually. Mine would wobble for a short time and then stop. My version that replaced the top repelling magnets with a motorized oscillator would continue to wobble, but that was because of the motorized oscillator of course.

A wobble caused by a little shock from the outside can take minutes to come to a rest, but the decline is quickly seen. Words are just words, we need a witness like you to be exact on your observations to be sure we have a real thing here.

I agree. That's why I did the next best thing and brought mine with me when I visited David so he could point out issues first hand. But yes, seeing a perpetually working one in person would be best. Unfortunately David's destroyed itself the first evening he tested it and since he knew it worked, he didn't see any reason to make another. Instead he focused on building his space ship version, which he didn't get a chance to complete. All we have are the results of conversations with David Hamel by people such as myself, and there won't be any new ones since David passed away in September 2007.

I have no idea how to picture the wobble going that strong that the thing develops anti-gravity... Just burning a little bulb or spinning a wheel with it would be enough for me. We need a replicable, mechanical proof of magnetic overunity.  Vince had the same problem: no alignment with our replications gives a permanent wobble. My compliments with your faithful research. Don't you have a video of your wobble?

Sadly, and I regret it more every time this comes up, to make room in my small place, I've since gotten rid of everything except the magnets and my two versions of the oscillator (the bottom part.) Back when I did my experiments back in 2000, I didn't have a video camera. But since mine would only wobble a short time, that doesn't matter. The animation on Jean-Louis's website is good enough to demonstrate the motion. His replication is only a replication of the demonstration of the butterfly motion and so is less useful than his animation for the purpose of replicating the 3 cone device. If you want descriptions from more people then you'd have to go to the yahoo group where there are plenty.

I also have only theories, and I can picture how it might occur. Being one who can't see how you can get energy from nowhere, I bring zero point energy into it of course:
http://rimstar.org/sdprop/hamel/hameltheory.htm
"The initial wobble of the magnets induces an electrical current in the metal cones and the exterior shell. This results in a separation of charge across the skin of the cone. Charge leaks out any sharp points, ionizing the air. The wobbling of the cones causes the ionized air to move around, including away from the sharp points, allowing more ionization. This ionized air fills the drum, including the area between the wobbling magnets located at the cone rims. This fulctuating magnetic field in the presence of ionized air results in a tapping of zero point energy. Somehow there is feedback which sustains the wobbling. If enough zero point energy is tapped then gravity effects may happen."
More is on the webpage. But that's just my untested theory.

If I were to build one again, having gone over two versions with David, I would embed my magnets in metal bicycle rims like David did so that my cones would get more contact with the fluctuating magnetic field (for my theory) and I would use the exact same magnets that David did. My cones would be metal, like David's, and the whole thing would be enclosed in a metal 45 gallon drum, like David's. The first rule of any replicator is "first replicate exactly." I started out without contact with David and with very little info, like you, and back in the days when there was only a short video lecture by Pierre Sinclair. Even after visiting David a few times and showing him two versions I still have questions about the rings of magnets attached to the drum wall. If I were to build one more version, I'd have to start from scratch.

Steve;

My replication would wobble and give the odd partial spin but would quickly come to a stop.

If you look up MYTHBUSTERS latest episodes you will find the show they did on antigravity devices.  They built a very close replica of the Hamel device complete with the 45 gallon drum. I got the impression from the show that the unit was balanced and did continue to wobble but I don't know for how long.  They did try to measure for gravity modification but got negative results. For them to go that far, I'm assuming that they got a fairly steady wobble in their cones. It is probably the best replication I've seen over the years but sadly it too, does not work.

Regards
Vince

Thanks Vince.
I've heard of the Mythbusters episode but I don't get the show myself and despite having looked for it online a number of times, have never been able to find it. If anyone has a link to where this episode can be viewed I'd really appreciate having it.

Also, if you do get a chance to enclose your 3 cone device, I'd suggest you make sure that the enclosure is electrically connected to the metal rim that the ring of magnets (the magnets that are in opposition to the cone rim magnets) is attached to - just in case it's important that the fluctuating magnetic field induce current to flow in the enclosure wall. I did get two weak positive results from mine when I ran my Mark 2 with a mechanical oscillator to create the wobbling and with it enclosed in a steel 45 gallon drum with just a small hole in the top. The first highly subjective result was that I think I smelled ozone, which would result if there was ionization going on inside. The second result was when I inserted the probe from an ion meter down into the drum such that it lightly touched the inside surface of the top cone (which was aluminium), it showed fluctuating ionization in sync with the wobble, i.e. changing amounts of charge on the cone surface. This makes sense as the magnets at the cone rim would have a fluctuating magnetic field which would induce electron flow in the metal cone. See:

Darn, I wish I still had the parts for mine!

The reason I see for the device with the ball bearing working is because you are chasing
it around on the table. The movement of your hand chasing it makes it keep spinning.
If it really did spin on it's own you could just replace the ball with a stationary bearing
and it would keep spinning in one place.
I see no mystery here.

By the way my girlfriend became interested in Hamel and ordered the whole package on his device.
In the videos he keeps mentioning the importance of using granite,
something about the characteristics of granite. He insists everything must be made from granite.

I'll second that, every Hamel spinner gets dragged/pushed around by the operator. It spins because the spinner is allowed to tilt slightly thus the ball contact point on the table is slightly off centre, this gives a tiny contact circle as it rolls around so only a small hand movement will cause quite fast revolutions.
