Can't get into either link. What gives here Ash? Can you perhaps tell us about that fridge - from what you read? Very intrigued.

Ash, that is an old story from the summer of 2007. Nothing since. Too bad, as that would have been a breakthrough

Here's a copy of the article taken from a forum, not sure if it's accurate, but does sound interesting. Opposing magnets, hmm where have I heard of that before..

Hey Freezer how can this technology only be 60% greater efficiency over a standard fridge if it uses no electricity.

Seems like this technology could also be used to heat and cool our homes also.

compressing fluids

Whenever you compress a fluid it heats up. Take the heat off under compression and release the pressure and the fluid is now cold. So why not compress fluids using super strong neo magnets attracting each other in a device like a hydrolic ram, or repealing each other at one end of a ram. This would compress the fluid and cause heat, take the heat off and the fluid is now cold....run that fluid into a chamber through coils to obsorb more heat and compress again with the magnets and do it all over again. It would work like a refrigeration system with no electricity used.

From Wiki:

The effect was first observed by the German physicist Emil Warburg (1880) and the fundamental principle was suggested by Debye (1926) and Giauque (1927).[1] The first working magnetic refrigerators were constructed by several groups beginning in 1933. Magnetic refrigeration was the first method developed for cooling below about 0.3 K

So they have made these way back then, yet:

This refrigeration, once proven viable, could be used in any possible application where cooling, heating or power generation is used today. Since it is only at an early stage of development, there are several technical and efficiency issues that should be analyzed.

Once proved viable?????
Early stage of development??
WOW.
80+ yrs is not enough time I see.

Hello,

Do I miss something here?

The magnets should still be switched on and off, or displaced to get a recycling process?



I once did a concept of a peltier based little configuration, with heating up one side, using the expansion to create a vacuum at the other side, freezing the fluid.

Two hardconnected cylinders, one filled with a fluid expanding by heat, the other with a fluid freezing by vacuum ( both could be water)

Now heat the one side with a Fresnel, fire, whatever...
The fluid will expand , pushing the cylinder out. The hardconnected cylinder on the other side is forced to rise along, creating a vacuum below, cooling the fluid.

Between that is a peltier, enjoying that little process:

Hi!

Actually, there is someting new happening in Switzerland. Here is some information about an academic publication written by a team of researchers under the guidance of Professor Osmann Sari at the University of Applied Sciences Of Western Switzerland IEEE Xplore - Sign In
