That is interesting. I wonder how much torque you can produce.
I was trying to find a place where I could buy some or better yet salvage it.
Thanks artv

I wonder if this would still work if one were to use cold and hot air to change the magnetic properties of the gd64.  That way, minimal energy could be used in the process via some sort of heat exchanger system.   For the 'heat exchanger', sunlight and dry ice could be used to heat/cool the air, and a low power pwm operated blower to move the air.   
Of course the goal would be to get more power from the rotational energy than is needed to operate the heating/cooling system.

@Brian516,

Gadolinium's Curie temperature is around room temperature. 68º Fahrenheit! 

"Unlike the other more common ferromagnetic metals, which have a curie temperature of well over five hundred Kelvin, Gadolinium's Curie temperature is around room temperature at 293 Kelvin. Besides being superconductivity at extremely low temperatures and is strongly magnetic at room temperature, Gadolinium is the only metal outside the fourth period metals that shows signs of ferromagnetic properties. Today Gadolinium alloys are used in televisions, MRI, and in microwaves but in the future its ferromagnetic properties can be used to detect cold or hot environments".

It only takes a very small change in temperature to alter Gadolinium's magnetic properties. The demonstration of rotary motion by Meir Alfasi  is awesome. We only have to fluctuate the temperature of the Gadolinium a very small amount to get it to grow strongly magnetic or completely inert. The possibilities seem endless. Think about a frigid climate. The rotor might run through a window. At 67º Fahrenheit, the element is strongly magnetic. At 68º Fahrenheit the element turns completely inert. So we only need to alter the temperature of the element by one degree to generate rotary motion.

Passing the the Gadolinium rotor blocks through a permanent magnet field alone is enough to alter the Currie temperature. Precisely temperature gauged with properly sized rotor blocks, correct spacing, rotor speed and permanent magnet field intensity, perpetual rotor motion might be attainable. The Gadolinium block would enter the field inert and emerge magnetic in the schematic below:

"Gadolinium alloy heats up inside the magnetic field and loses thermal energy to the environment, so it exits the field cooler than when it entered".

The Gadolinium rotor block would be drawn into the permanent magnet field at precisely 68º Fahrenheit by the magnetic attraction. This force would power the rotor. Initially, the block would heat up, and traveling at just the right speed, the preliminary rise in temperature might be sufficient enough to briefly push it just above the Currie point to turn the block non-magnetic and allow it to pass through and escape from the field before the cooling effect set in to return the block to the magnetic state. The rotor block would need to warm up a little before it came back around, because the process would have an overall cooling effect. Ambient room temperature might be enough to warm the blocks sufficiently at just the right temperature. A temperature controlled environment, like a glass box would need to be heated a little to sustain rotor motion. The sun would ultimately sustain the power to continuously run the generator.

That sounds pretty complicated.
Why not just have a wheel with the bottom half in a cold running stream, and the top half travel through a solar collector?
Just thinking.....artv

@shylo,

These 10cm Gadolinium cubes run $31.00 apiece off ebay. They advise you to keep them away from water because they tarnish fast and shed a flakey scale.

Placing the rotor in a sealed plexiglass box placed over a heating pad would protect the cubes and allow for precise temperature control. The magnet generator would only require the addition of two permanent magnets to complete the unit.

Can you seal it inside aluminum?
Put it in an airtight membrane.
Shouldn't be to hard to make it waterproof.

@Shylo,

A Pelton wheel could generate a good deal of power just from the water flow alone, but sure, it would help to protect the cubes that way.

"Instead of ozone-depleting refrigerants and energy-consuming compressors found in conventional vapor-cycle refrigerators, this new style of refrigerator uses gadolinium metal that heats up when exposed to a magnetic field, then cools down when the magnetic field is removed"

Think about it; There's no cost to a permanent magnet field. At 68º, the Gadolinium is attracted to a permanent magnetic field. The temperature only has to rise a tiny amount for the cube to unfasten and freewheel. All the rotor needs is a correctly spaced cooler Gadolinium cube in front of it to push the demagnetized cube free of the field and voilà! Perpetual motion.

Here's a guy who has apparently perfected one already:  "Gadolinium Magnetic Generator".

I have a boule of GGG (Gadolinium Gallium Garnet) that was grown at Bell labs. (It is single crystal)  It is about 1.250" dia. x 6" long.  I wonder if this would do anything in this application?  I have never tested its magnetic properties...perhaps I should?

@Pirate88179,

It should warm up enough in a closed fist to pass through the Currie temperature of 68º Fahrenheit and lose it's magnetic attraction.

@Pirate88179,

That paper I posted a link to list many things I need to have time to read.  It appears that it is not magnetic at room temperature here....at this point. (around 65% F)  I can heat it in my hand, or wherever but, it already does not exhibit magnetic properties at room temp.

Perhaps I should place it in my freezer to see if it becomes magnetic?  I think the paper was talking about much lower temps than that...but am not sure.  This boule looks not much different than my single crystal sapphire one except it has a slight coffee color to it.  My ruby boule is, of course red, which is really just single crystal sapphire with .05% chromium added.  (These were grown for ruby lasers)

I will look into this further but, initial tests with a neo show no magnetics at 65% F.

Bill
