Greendoor GravitoMagnetic Heatpump Engine <<<

This should work, as it is based on solid conservative physics ... save this page before the MIB close it down.

I hereby donate this idea into the public domain so anyone can construct this device and market it.

The operating principle is based on Lord Kelvins finding that steel, as it is being pulled into a magnetic field, gains heat.  That heat is generally lost to the ambiance surroundings, so when the steel and magnet are seperated again, the steel loses heat and becomes colder than ambient.  There are modern magnetic heat pumps and refrigerators based on this principle - nothing new here.

Now imagine a balanced gravity beam (or wheel - but to show the working principle, imagine a beam).
Two identical steel weights are balanced at either end of the beam.
Below each steel weight we have identical strong magnets.
The beam is balanced in the horizontal position.
If the beam is overbalanced to the left, the left hand steel weight (LHSW) falls into the magnetic field and heats up.  The RHSW is pulled out of the magnetic field and cools down.
The converse is also true:
If the beam is overbalanced to the right, the right hand steel weight (RHSW) falls into the magnetic field and heats up.  The LHSW is pulled out of the magnetic field and cools down.

Now imagine two identical pneumatic chambers or airbags.  These a designed with a piston or diaphragm that expands or contracts as the pressure rises or falls.  A weight on a lever is attached to this piston or diaphragm, so the weight moves as the airbag expands or contracts.  These are little more than a powerful version of a barometer.

These airbags are mounted on top of the steel weights - and after an initial overbalance, the cycle now begins:

The LHSW heats up in the magnetic field.
The RHSW cools down as it has been pulled from the magnet.
The LHAB (left hand airbag) heats up, and it's weight is moved closer to the fulcrum.
The RHAB (right hand airbag) cools down, and it's weight is moved away from the fulcrum.
The beam/wheel is now overbalanced, and falls to the right hand side.

The cycle now repeats, and alternates indefinately.

This is rather like a drinking bird stirling engine device - but it is making it's own heat gradient.
Gravity provides the force that pulls the overbalanced weights both into and out of the magnetic field.

There is no reason why this should not work.

Overunity - right here, right now.

Go build and enjoy!

If the left hand steel weight is attracted to the magnet, they is no way to disconnect it from the magnet. they are something I maybe dont understand?

You have to realise this is a perfectly balanced beam situation.

The force of attraction is the same on both sides.  At rest, the beam is horizontal.

Therefore, the force of attraction to pull the steel into the magnetic field on one side, is perfectly balanced by the force required to remove the steel from the magnetic field on the other side.

Therefore the only thing causing the alternative motion is the position of the weights attached to the airbags, which are moving their centre of gravity depending on the heat generated, or removed.

Magnetic heating or cooling is not disputed.
Balanced lever systems are not disputed.
Basic pneumatic principles are not disputed.
This thing has to move - and having moved, the temperatures have to change.
When the temperatures change, the airbag weights have to move.
When the airbag weights move, the beam is overbalaned and has to change sides ...

You may ask where energy, or surplus energy is coming from.  One thought is that when you have a cold steel weight (aka magnetic refrigerator), there is heat energy from the ambiant surroundings rushing into this to heat it up.

On second thoughts - I think this would just stall in the balanced position.

Heat pump technology is looking like the best bet for useful free energy for me. The drinking bird really does work. And several drinking birds can be assembled into a wheel. But it does require a heat differential.

A warm water bath, connected to a heat exchanger buried in the earth would provide a source. A reflective mirror chamber, directing radiant heat out to a cold part of space could provide a useful sink.

Imagine a wheel consisting of a lot of drums of refrigerant. The spokes would be pipes, connected at the other end to a condensing chamber. In action, the bottom drum would be immersed in the warm bath. The refrigerant would evaporate, and rise up the vertical pipe to the top. The condensing chamber (which is obviously the same as the bottom drum but upside down) would be in the reflective sink area at the top of the wheel. The refrigerant would condense back into liquid and refill the drum at the top. Several such balanced systems arranged into a wheel would rotate slowly with great torque.

On third thoughts - i'm not at all sure that Magnetic Heating can't deliver free energy ... think about this for a minute:

Reducing it to the simplest experiment:

Imagine a device that consists of a steel weight, a spring and a powerful magnet.  The device is constructed so that the spring opposes the attraction of the magnet & steel.  The are various configurations - imagine something circular like a plumbing checkvalve, but it could be a lever arrangement or anything that uses the same principle: spring opposes magnet.

Carefully adjusted - we should be able to move the steel into the magnet with a feather weight.  And we should be able to move it back out again with just as little force.  Think balance (which is what I was going for with my gravity beam idea).

Now scale this up - say 10 tonne magnets with 10 tonne steel weights.  Still perfectly balaned with a powerful spring (or gravity if you like).  If friction is kept low - the force to move the magnet & steel in and out should be minimal ...

And yet we should be able to get some significant heating, followed by signicant cooling ...

I think the party is back on ...

The magnetic field decreases entropy by forcing order.  We can cycle back & forth from high to low entropy with nothing but frictional losses ... and create a useful alternating heat differential way beyond those frictional forces (I believe).
