Power from repelling magnets

[norman6538]

I have been able to piddle around in between Dr. appointments and went back to the Lafonte device with an off center axle and the attracting magnets on the shorter end so they are closer and will attract. Which they do until the repel gets lined up. Then when the 2 arms are lined up the axle can be shifted to the center where equal forces will allow the 2 arms to be separated where power from attraction can be harvested again. The problem was I first made it as a rotor and due to the magnetic field rotations the 2 arms will never line up so I went to the scissors device where they will lineup and have an equal force. The trick will be where does the power come from to shift the axle. A solenoid would to that very well but it would have to connect to both axles and then release the former pivot. So it becomes a leverage shifting device with magnets. And what we are accomplishing is effectively turning the attraction on and  off to do useful work.
Then by cascading that to 2 larger devices it should be possible to get 10-20 times the power out.

To be honest, i don't understand what you made.

The problem, can you measure? As i don't know how it works, i cannot figure out how to measure.

The problem, the citfta device, with the shield magnet and linear movement, while simple, it is likely very difficult to make. The linear movement on ball bearings, kind of metal work? And at that, it seems to me that the citfta's device doesn't even have a movement fully on ball bearings, there seem to be like two ball bearings, and the other sides are without ball bearings... And it seems that in spite of ball bearings, the friction is quite high there.

So maybe a rotary device would be better, and it may be possible to measure it too. just measure force after every small distances, even if it rotates. Cannot figure out how though, without knowing the device.

One more thing, you were not quite right. It is true that an iron shield attracts to the position, and it is like output. But the problem is, it has to be pulled out, when it is between two magnets, and this is twice as much of energy. The shield magnet in theory needs no force when shifting in and out, in theory it should completely work. In practice though, only measurements can show.

The problem, the citfta device, with the shield magnet and linear movement, while simple, it is likely very difficult to make.   Anyone with some patience and normal hand tools could make what I have made.  The linear movement on ball bearings, kind of metal work? A hacksaw, a hand drill, some drill bits and a couple of files are all you need to do the metal work.  And at that, it seems to me that the citfta's device doesn't even have a movement fully on ball bearings, there seem to be like two ball bearings, and the other sides are without ball bearings...  There are 6 bearings supporting each piece of aluminum angle.   And it seems that in spite of ball bearings, the friction is quite high there.  Wrong again!  The friction is very low as you can tell from carefully watching the video.

"Wrong again!  The friction is very low as you can tell from carefully watching the video."

From carefully watching the video, i see that the force was 3 to 4 ounces when moving the magnet towards the shield magnet, while there shouldn't be any force at all. And there was 7 ounces of force when shifting the shield magnet. Ok, maybe because the shield magnet touched the other magnets, but even without it there was still 5 ounces of force. I don't see this as a very low friction, but of course i cannot know what it all may be caused by, i didn't do the experiment. I just say what seems to me after carefully watching the video, and i watched it very carefully. What concerns ball bearings, on the left arm i saw only two ball bearings, and i cannot figure where the others can be. I cannot be sure though, as i cannot see inside your device.

And better don't move towards the right magnet when measuring the output forces, this is wrong. Because then you add the friction force to the output force, measuring considerably more output energy than there actually is.

Attached is a photo of the off center axle (at the nut) in the attracted  position. As you can see it is easily made of tongue depressor sticks and hot glue. If you pull the attraction magnet on the left down it will jump right up because it is closer than the repel on the right due to the leverage advantage of the off center axle. The center axle is just to the right of the nut. I put this together last night in an hr. and got photos and a video. If you are a "bencher" you can to it too.
I'm sorry about the large photo, I shrunk it to 1/3 and it still got too big.
