Power from repelling magnets

[ayeaye]

Have you measured your force?

No, i said i tried. But the force is so small that i don't even see the disc in the spring scales move. In spice that i can clearly feel the force by my hand.

Ayeaye said "Again, in your Lafonte scissors both pairs of magnets attract, did i understand correctly? Assuming that it is so."  - false assumption. get off the keyboard and make one and then you will learn something. One attracts and the other repels but always at the same distance so they are always balanced just like the scissors. But I prefer the linear ones because they are easier to adjust and there is not angle changes.

false assumption

Thank you, i needed to know that. Thus one pair of magnets in the Lafonte scissors attracts, and the other repels. So this is like balancing forces. Both opening and closing the scissors needs very little force. But when it is only balanced forces, then there likely is not much output energy.

My health has recovered enough to continue my work started here. I am trying to
exploit the power between 2 repelling magnets when they push apart by first
  inserting metal to make them attract onboth sides and then when the metal is removed they
  will separate and release the power for our use. My work is always rapid
   prototype and crude but here is a peek at what I accomplished. The third
   photo shows the entire setup. The first photo shows the variable lever setup.
The second photo shows the basic device setup that has 2 repelling magnets with
metal between them.  A bell crank with connecting rods makes them open and
close equally together. Then off to the right not seen but in the second photo
  is a variable lever with a RadioShack magnet (weight only) to counter balance the
  attraction forces of the magnets to metal. Then adding a 3/16 nut is enough
  to make the arm drop 1.25 inches. That pulls the metal away so that the
  repelling magnets separate to lift the output variable lever. Then not seen
  behind   is another variable lever attached to those magnets which lifts 6 of
the same magnets 1/2 inch. Which means that using
(1 nut x 1.25 in travel is a unit of work) 1 unit lifts 6 magnets 1/2 inch.
   Thus 1.25 units in / 6 x .5 = 3 giving a ratio of 240% work out vs in.
   I have achieved this with 2 other permanent magnet devices but its not
   enough to reset and repeat to make continuous motion. BUT IT IS OVER UNITY.

I will try to refine this to do better because the variable levers are not
precisely configed. I used what was lying around from past projects. They need
to be sized for the mechanical travel distance to match about 1/4 the
circumference of the circle. The film canister in the input is too big and
needs to be down sized and the output might be too small. If you hook 2 equal
variable levers to each other they will balance no matter where they are
positioned just like 2 equal weights on a pulley and string.
I use adjustable stops on the left to keep the metal from dragging
on the magnets and requiring more work in.

The last photo shows the output variable lever with 5 nuts like the 1 input nut.
And the yardstick has 2 sets of markings - blue is the distance lifted for
the output and masking tape is the nut dropped distance markings

I hope this will encourage you to do your own work to get power from permanent
magnets.

If I had a fraction of the money spent this weekend on "the game" I would have
a self runner.

The leverage on the variable lever changes as the arm moves from horizontal where
its max leverage occurs. The leverage is not the radius of the arm but the
distance of the weight to the axle. At horizontal leverage is maxed but at 85
degrees either up or down the leverage is very little and thus is intended to
approximate the magnet closer stronger, further weaker characteristic.

Since my heart/breathing/circulation has improved so much I am on a roll again. I realized that my film tube had too much travel and not enough angle change in the movement so I made a smaller one which gives more angle/leverage change and I am working on multiple weights at various leverages to match the closer stronger magnetic attraction characteristic. So in this photo you can see the beginning of this and what it means. There are 3 different weights at 3 different leverages. The arm/weights are balanced at this point but as the arm goes down to horizontal the 2 weights on the left are not necessary so I will "sit them on a floor" so that they are not a penalty when going back up.
see photo for the idea. I will use strings to hold the weights which will "sit them on a floor".
So when the forces are balanced out just adding a small weight will make the arm drop and removing it will allow it to go back up to repeat the cycle.

My real purpose in all of this is to demonstrate that not all energy is conserved in all cases. So in this concept a balance is made between magnetic forces, gravity (could be springs), and variable leverage such that we release the magnetic repel power with a smaller force.
