Magnetic OU principle, You should really take a look at this !

Hi Wiz

Not sure why it doesn't work for you but I was able to play the "Time to wake up" video on the http://www.forgotten-genius.com/documents/in_the_news.html site, if it doesn't open for you maybe try this direct link to the video on Youtube:

Hi all

Amazing. magnets can not do work they say 

This works on equilibrium principle. Would be nice to hear from the maker for details.
Fantastic. what a workmanship. but I think no fanners here.
Anyone knows more about this ? Or we should make a trip to china and learn language and writting ?

6. conversion of linear mech energy to electrical using linear permanent magnet-coil arrangement.

I can see a small problem with that. On the power stroke all will be well and we can extract energy from a coil. On the return stoke we are relying on gravity to pull the stack back down while we extract an equal amount of energy in the other direction from the coil. This will create drag on the mechanism and the stack will fall slowly reducing the efficacy of the machine.

What is needed is a restoring force that can do as much work as the power stroke - a spring perhaps or a design where stacks operate in pairs and the power stroke of one resets the other.

I also see a small problem with the cost and size efficiency of this machine. To take the example above of 300 lbs force and 6 inches travel. If a stack can be operated at one Hz this come out to a shaft output per stack of about 200 Watts for a machine with fairly large and expensive neos and quite a bit of steel. Obviously the machine will be more cost effective if it has many stacks and few magnets to increase the power strokes per second. Then again a machine with a suitable stack restoring mechanism might allow the stacks to operate at much more than 1 Hz - I don't know.

As for the COP, I think this will depend mostly on how large you build the machine. Doubling the size of the machine should not double the input power (which is still required only to overcome rotor friction) but the output should increase by a huge amount with larger magnets and more steel. So the bigger you build it, the higher the COP. That's my theory anyway.

Just my thoughts. Hope that helps.

I've drawn a diagram of how I currently envisage this thing. I've omitted a few bits for the sake of clarity. In addition to the stacks shown, there would be two more at 90 degrees.

There are two magnets on each rotor and they are 90 degrees apart one rotor from the other.

Output is of course taken from the reciprocating cylinders linking the stacks.

A means would be needed to support the stack central columns while allowing the stack cylinders to reciprocate.

Plus a motor to drive the rotor.

I think these mechanical solution presented over here are
interesting and might work,
but to get the COP really into the range of 20 to 50 you have to go with
electric power input.

The easiest thing would be a tunable LC circuit, that runs
on the same resonance frequency as the reciprocating
output frequency of the square washers pushing back and forth.

Have a look at this video to see the effect
of the low resonance input power into the driving
LC tank circuit.

In this video you would just use the left shown LC tank circuit
in the circuit diagram to drive the washers back and forth.

You need to wind the coil around the core of the soft iron core
pieces that conduct the magnet flux into the airgap,
where the square washers move back and forth.

So no magnets are needed at all.

At the resonance frequency of the LC circuit this
motor will run only on very low input power ( just the coil windings
and iron core eddy current  losses, you can see it in the video: the lightbulb goes
very dim, so not much input current is flowing= very low input power)
and have a huge mechanical power output.

P.S: Surely the resonance frequency must be set lower  via the
LC tank circuit  than in this video, maybe just around 10 to 100 Hz ,
so the
"washer piston" will not fly apart.
