Magnetic gadolinium fridge

Hello
have you read the article about the latest science and life on the magnetic fridge?
if so what do you think?
Will it really be the fridge (or air conditioning) of the future

here is the scan of the .A principle when replacing compressors
can be in a century like the explosion engine

it's a nice technology, but not for now
Apparently what the designers think:

A green technology Although this "cold technique" is still only at the prototype stage, it is still full of promise. "In terms of energy consumption, its efficiency is 40% higher than that of a traditional fridge, observes Nicolas Erbeau, engineer and scientific assistant at the Institute of thermal engineering of the HEIG-VD. Above all, it could replace facilities that still use CFC (chlorofluorocarbon) or HCFC (hydrochlorofluorocarbon) fluids, which are harmful for the environment. "The new environmental regulations to eliminate these refrigerants are likely to stimulate the development of alternative technologies such as magnetic refrigeration.
The search for the ideal material Still, while this technology can boast a huge potential market (air conditioners, refrigerators or car air conditioning among other opportunities), its development and marketing still face a major problem: that of the ideal material.
Indeed, the magneto-caloric material currently used by the prototype is gadolinium, a "rare earth" used pure. An unsatisfactory solution. "It's an expensive metal, flammable in contact with water and dangerous if its particles or gases are inhaled," says Osmann Sari. And while some problems can be solved, gadolinium is clearly not optimal. "
