Here's two  SMOTs of mine.
Yes, they lift a ball, and after adjustment even it falls and rolls, but... as soon as a level of the beginning of movement correspond to a level where the ball falls, it does not roll, only remains, where has fallen. It is impossible to deceive a magnetic field...

can you make the ball to NOT fall horizontally? I mean (my bad english), put something there so the ball doesn't fall all the way down but rolls down and away, increasing it's velocity, encountering another smot on it's way?

Seems to me, with a few simple modifications the ball drop could be controlled, and more energy could be preserved off the end of the ramp. If you cut the track at a radius angle to allow a smooth transition off the end of the ramp, and cut a small clearance notch in the bottom of the track to allow for the ball passage, it should guide the ball off the ramp at a higher momentum, and allow you to control the transition.

Also, if you cut the ends of the bar magnets away from the track at the end, the magnetic flux would have a different orientation, and a strength gradient, that would help to guide the ball off the end of the ramp, instead of applying back force on it at the end of the ramp.

Also if you had the ramp lift slightly above the level of the mags at the end of the ramp, such that the magnets transition from pulling from the sides to pulling from the bottom, we may get better results, but I'm just guessing. I've always thought that if a SMOT ramp, transitioned to an adsitt ramp, we'd get better transitions off the end of the track. I didn't add this, because I'm not sure. I am however positive the first two suggestions would help.

Attached are some illustrations to show you what I'm talking about.

Regards,
Gn0stik.

What you don't seem to understand schriss, is that we've all tried to figure out ways to do that. That is in fact THE problem to overcome with a SMOT. And without using gravity to break free of the magnetic field, so far, we've been unsuccessful. That's why we "drop" the ball. However we might be able to avoid dropping all the way back to the beginning point by doing it this way and preserving some of the forward momentum.

If we use the forward momentum to slingshot the ball around the radius, perhaps we can get a little more downward momentum on the otherside of it, to propel it into a track at a higher level than we started.

But who knows perhaps that would work. I haven't tried the modifications I suggested, so who knows.

It's made exactly the same way, but this is not a point. We can make the ball run, but we can not make it run to higher level. The point is, when levels are the same the ball can't roll away from the ramp, not enough power to overcome the field. When it fall far enough from field, yes it can roll...but level is to low to let him get back to ramp.
But like  gn0stik  said "who knows", needda more practice...

Ok,
 I'm kinda new to this so forgive me if I sound a bit backward...
I know this has been hashed over quite a bit and I plan on trying out a few ideas (which I will share, of course) in the meantime, I have a question. How about using stronger magnets and steeper ramps?

P.S. I found a site that carries some interesting items including awesome magnets:

Fine, then can you move what I added, halfway down? So the ball WILL drop, but not on the ground, but on the curved surface that will make it start rolling? What's the problem here, are the magnets on top still holding the ball?

Nevermind the above, just saw the latest movie and the ball rolls away can't it just roll into another smot?

Yes it can, in fact J.L. Naudin did that in one of his experiments called "SMOT 2.0". However the second smot had a lower starting point than the first one, and the final height was even lower than the second one. Basically what you've got here is a slinky, which also can be seen to be self motive, but you've never seen one going up the stairs have you?

May I suggest looking at Don Adsitt's ramp?  It is interesting to watch the movies that he has made.  The ramp track has hills in it in the last movie.

Here is the web site:

The SMOT ramp should be longer and steeper, and from what I see from J. Naudin, the ball really drops down and away from the smot. The lifting height, however, is not high enough to let the ball drop onto a uniformly declining circular track. If we can lift the ball three to four times its own height, say, and still manage to have it drop down, then you have enough space to put a track underneath its exit point to bring it back.

Anyone up for a challenge to make the SMOT ramp a little steeper and longer for higher lift? We really need some more lift.

Yes, somewhere I've seen a video of one of these turning quite quickly. It wasn't a wheel though, it was two balls, one on each end of a spinning armature style rotor.

Where was it? PESWiki maybe?

SMOT has not overunity
« Reply #103 on: June 27, 2006, 05:27:04 AM »
sorry I'm english beginner

I make SMOT and experiment

but I can't confirm overunity

start point hieght : 6cm , ending point height 5.5cm

SMOT is an optical illusion

It looks like you've only elevate the magnets and not the ramp. In other SMOTs the ramp is more elevated than yours.
