Magnetic Fridge Cuts Energy Use In Half

by Editor

A really cool invention by Danish scientists is set to make us rethink the conventional refrigerator. The invention uses very powerful magnets to reduce temperatures by up to 20.5 degrees Celsius whilst producing 100 W of cooling power.

This comes as a great breakthrough in refrigeration technology as we rapidly consume and release greenhouse gases in an attempt to keep things cool.

Refrigeration is one of the hallmarks of our modern world and consumes masses of resources as we as a species like to keep things cool.

Keeping cool and saving resources!

Using magnetism to create a cooling effect requires very little energy. It’s also possible to use water instead of harmful greenhouse gases to transport heat and cold. The term ‘refrigerator magnets’ has been given a completely new meaning.

Using powerful magnets, Danish scientists claim to be the first in the world to lower temperatures by 20.5 degrees Celsius, while at the same time producing 100 W of cooling power.

“No other research groups that work with magnetic cooling have managed to do that,” says Christian Bahl, a senior scientist at the Energy Conversion department at Denmark’s Technical University (DTU), who was one of the researchers behind the so-called MagCool project.

This breakthrough in refrigeration technology comes just in time as the worlds energy supply is already suffering as a result of excessive consumer demand.

Unfortunately at this stage to cost of producing magnetic refrigeration makes it non commercially viable. The strong magnetic field contains a rare metal found in soil called neodymium.

The trick is constructing a sufficiently strong magnet which uses as little neodymium as possible will make the fridges viable in the future.

Do you think that we need to be doing more research into these kind of technologies if we are to survive into the future.

Would you use a magnetic fridge despite the financial cost? What do you do around your household to reduce energy usage? See the clip in the top right of this post for some tips.
