TD replications

                       No O.U. in the all magnet twist drive.

An input of about 80 grams (average force) on the "SL" sliding unit,
over 22 increments of linear displacement....

causes the lifting of 135 grams over 42 increments of displacement.

80 x 22 = 1760  work in to 135 x 42 = 5670  work out.

5670 / 1760 = 3.22 times more mechanical work out put than
mechanical work input.

But the process when reversed, has precisely the opposite ratio.
Therefore during a full cycle operation the work in to work out
cancels.
                         No net gain !

Something similar could be done with springs and levers. 

                          Note... I say similar but not identical.

1. In loaded spring designs I have examined,  there is a spring / force, loading
present in that part of the unit (which is analogous to the SL magnet / linear
motion unit) which does not exist / is not present, in the magnet rather than springs,
builds / design.

2. The magnets, if electromagnets and unlike springs, can be switched on and off.   
                                          Full cycle operation could then be O.U..

Note..

It is only my opinion that electromagnet use, can yield an O.U. result.

Energy input in electric form, would need to be measured as expended in
either one or two electromagnets.

One electrical input, if a single electromagnetic coil (no core ?) is used along
with one permanent magnet.
             or
Two electrical inputs supplying two electromagnets (both with cores).

The mechanical energy input upon a single one of those magnets (the SL)
must also be included as joules of input energy.

It remains at this point, that the calculating of joules per second  (power) is not
necessary in to determining the energy input to energy output ratio.

It is not my intention at this time, to do those explorations / measurements.

To hell with the electromagnet ideas. 

I stumbled on a fix for GoToLuc's torque amplifier. 

See the jpg file below.  Very simple, wow.

I call it luc's times 1/2, times 4

note that shoud be flush not fush

This is Luc's original design

At first the original may seem identical to this modification, but
its not.

Ah Floor you got me hooked again. I made a rapid prototype and it works an has a great escape. I used  1 mag on the pendulum and 2 on an arm with travel stop limits and it works the same as GOTOLUC. Then I removed the mags and the pendulum swings free so there is a bit of a stick spot but not a fully stuck spot.
Now as I have said before great ideas but where are  the measurements that tell the final story.
I had 2 sets of magnets with different gaps between them to see if I could reduce the travel of the input work of the pendulum and it seemed to have more sticky spot to overcome.
