Do we have a real list with facts?

Eric,
 Details are what we are lacking so a good replication is going to be lacking.. Somewhere he stated he thought the screws are 3/4 inch long. Still no details of the screw size like #8, #10, #12, etc.. No details of how many screws going around the outside of the PVC pipe. No details of both horizontal and vertical spacing of screws. He did make a brief mention of the magnets being grade 45 or so he thought. For a grade 45 they are awfully weak for pulling the screwdriver in the video. If they were grade 45 I think he would have had to pry the screwdriver away. I am hoping he comes back with more information and a better video.
If not we can still use the video supplied to try to replicate but that will be more hit and miss. Just from looking at the video I would say they are #12 wood screws with spacing about 1/4 inch horizontal and vertical mounted on a 4 inch PVC pipe. It maybe a 3 1/2 inch PVC pipe. Screw heads appear to ground off on one side up to the shaft then glued to the PVC. Still too much missing information.
 I am kinda bothered that he stated that this PVC pipe ran for a night but instead of presenting the PVC design he is now presenting a steel washer design. Why change ? Seems strange to abandon a working design so early in the game if it ran for a night.
Maybe after this weekend we will have more video and more details..

Later,
Tom .

I agree. @xpenzif should be more forthcoming if his creation is to see the light of day. Otherwise it will sink as many other seemingly working devices sank when their creators were approached for details only to disappear. Also, I' m seeing that various people are giving him advice which doesn't belong to this stage of the development of the idea. I think @xpenzif should learn to be himself and not listen to anything which would distract him from the main goal--establishing of his experiment as legitimate by having independent parties replicate it. I'm saying this in principle. Of course, I don't know what his exact attitude is regarding these matters. Maybe, for instance, he's too busy now and doesn't have the time to chat in this and the youtube forums. Anyway, I think you're quite right, it has to be impressed upon him that he shouldn't abandon a working model and get into a chaotic, unsystematic activity to improve something that hasn't yet been established. It will be very detrimental to the development of this important idea.

Off to make the bracket to mount 4 magnets on, but so far as below and mounted on a HD bearing for now.

Still before I sign up for machine shop time I want to see a better video and some more details. Machine shop time cost $$..
Later,

I wish I got into this stuff back in school..  I had a cnc, mill, vaccum former, table saws, band saws, sanding chambers, and every tool all at my finger tips.  I wonder if the inconsistencies in the screw gap distances cause a acceleration and deceleration which is the mechanism which allows for the effect, just a thought.

Nice as always.    Just a suggestion to make sure and glue those screws on well, as the magnets will pull them off if its too close.

I'm wondering if one could use the magnet sheets that they sell at home depot etc. to cut out these triangular shapes. This would take care of the problem of the screws eventually becoming magnetized.

Good luck. Just to mention, did you notice that in the original the heads of the screws are flattened, as we discussed above? Perhaps this won't matter. Let's see. Also, is it me but it seems that the PVC base isn't exactly a cylinder. Also, the magnets aren't aligned quite perfectly. Look at the third from the top. The top magnet seems closer to the screws than the bottom, etc. It's amazing that even such an apparently crude construction turns as nothing else so far does. Torbay's wasn't perfect either but we never saw it in action (except for that propaganda clip where details were smeared, nothing like here).

I think screws getting magnetized should be the least of your worries at this point. Show a replica making full turns, as many as in the video, possibly a little more, and then we'll worry about magnetization of the screws (no worry at all).

[eavogels]

Flattening of the heads of the screws is seen when carefuly observing the close shots in the video. Also, it was mentioned in the youtube discussion.

I found it. He wrote:
Honestly screws were a bad idea and took a lot of work flattening, you can probably find something better than screws.

When looking very close; the whole screw was grinded in the shape of the PVC.

Well I was also thinking it would make it easier to build as the magnetic sheets I'm talking about have adhesive already on their backs.

That's a mistake to abandon the working model and push everyone elsewhere into untried territories. This absolutely shouldn't be done. Reproduce this exactly as is and then further it.

As for the screw ground into the shape of the PVC, I don't seem to see it. It appears to me that both the front of the head and the back are filed so that the screw can lay flat on the surface to a certain extent while the outer surface goes flush with the stem of the screw. What is relied upon is the fact that the thicker part of the (already flat) screw is attracted more than the thinner one. This is what @xpenzif also says in the video.

What about the design in the above link that I posted earlier?  I am working on a similar design but it is very related to the video discussed in this thread.  Does anyone think this video is faked?  Or maybe he is using pulsed electromagnets?  I will try to post some pics of my device.  Thanks.

Well, if your device works, that is, turns without any input energy as in the discussed device here that would be fabulous. Waiting to see it.

@xpenzif's device seems as simple as can be, though.

Okay, I grinded a screw. I held one against my grinding wheel and I grinded a bit of the whole side of the screw, not only the head. Now the part of the screw that is left, fits very well on the round PVC. I tried to make a photo but I cannot zoom in so I made this drawing to show what I mean.

Hi Ommibus and everybody!

I agree with you about trying to replicate the initial model as accurate as possible.

BTW1: I also think that the "the whole screw was grinded in the shape of the PVC". (Eavogels).

BTW2 : have you noticed that in the Steorn forum 'they' (this load of spektic trolls) seem not to be interrested in this device and seem to prefer discussing about useless topics? Are they not?

@Omnibus:

Yes, it is very simple, which is usually best right?  Someone mentioned the fact that the screws were not all in a precise allignement.  I also believe it is possible that it is this non-precision that possibly eliminates or greatly reduces the sticky spots.

I am not using screws on my device and I don't consider it a replication.  I have magnets around a drum mounted on my good old hard drive spindle motor in a helix pattern, similar to the screw layout.  I am now constructing the stationary post, or posts which house the repulsion magnets that line up with the ones on the drum.  Thus far, I have to say that I still feel sticky spots when experimenting by holding posts in my hand. It runs for a 1/4 turn before finding equilibrium. I am going to mount the posts and experiment with polarity and angle changes to see what happens. I'll try to post some pics tonight.
