A group of researchers at the Technical University of Denmark’s project laboratory in Risi¸ have discovered a cooling method that uses magnetic materials instead of electricity, reported daily free newspaper Nyhedsavisen.
The invention will allow for refrigerators to replace existing electric refrigerators in homes and businesses with a fully environmentally friendly power source. Although the first prototype will not be ready until 2010, the project’s researchers say the appliance’s cooling cycle efficiency will be 60 percent greater than that of conventional refrigerators.
The new method uses opposing magnetic fields to increase the temperature of the materials employed. The heat energy is transported through a non-volatile fluid, such as water, and then thermodynamically reversed to a cold temperature. The scientists have already been able to cool a 20° C room to 11°C using the new technology.
‘It probably isn’t realistic to believe that magnetic cooling technology will be immediately available for consumer use, especially as refrigerator manufacturers have brought prices down so much in the past few years,’ said Christian Bahl, one of DTU’s project researchers.
But Bahl said another of the magnetic refrigerator’s advantages is that it is silent.
‘So it will likely be first used in various niche areas, such as places where a quiet environment is an important factor.’
Although magnetic cooling is not in itself a new research field, the DTU scientists were the first to use the technology in an actual physical setting to cool room temperatures.

Preview of a Mendocino Motor (solar power/magnetic levitation)
We will present a tutorial for making this kind of motor in the near future. I think it’s a great idea combining the solar power with the inertia given by the motor’s movement around its axis, floating in the magnetic field.
Levitating Magnetic Wind Turbine – efficiency made in ChinaWhat could result if you combine magnetic power, wind power, and a huge-sized facility? Energy!!! It even results a lot of energy. How do you call it when you put in 53 million dollars and get 214 million dollars out of it? Profit! So… profit+energy=CHEAP! The chinese have done it again! They are now building [...]
How To Build A Free Energy Magnetic Water HeaterThis heater is related to the transformation of magnetic energy and certain gases directly into heat energy without the use of ignition, as we know it. It is a heat-producing device that will greatly reduce atmospheric pollution and conserve energy. This device includes two spherical hollow pressure chambers that are joined together at a mixing [...]
Perendev's Magnetic MotorThis motor is called the Perendev Motor and it works by itself. It uses the magnetic power from the permanent magnets (neodymium magnets) to self-propel. You only have to close the stators to the rotors for it to start spinning. Perendev is said to have made higher power versions, but none had been sold to [...]

You Not going to see small versions of these in your PC cooling usage though as Magnet’s and electronic CPU etc dont work too well there
well Not until you have Lightpeak style Pure light CPU’s and components in the far future at least

quite interesting,pls keep me posted

Magnetic cooling has no magic behind, we have working model since 1933. The principle behind it never break any rule of physics. Nowaday researchers from all over the world are working on how to make it marketable. More important, it has nothing to do with “Magnetic Power”.

Info is not accurate. Check Wikipedia for more info…Danish group has not doen anything new yet!!

This technology can’t replace electric refrigerators in the absolute sense.
Electricity will still be needed to pump the fluid and run other functions, even
if they are able to accomplish the other things implied by this article.
