Cách nam châm có thể thay đổi tủ lạnh và máy lạnh của chúng ta mãi mãi

For centuries, refrigeration tech has stayed the same — energy-hungry and reliant on harmful gases. Enter magnetocaloric cooling: a new solution claiming to be 30% more energy-efficient than current cooling systems. And it's scalable. From fridges to cooling buildings and server farms.

We're destroying our environment at an alarming rate. But it doesn't need to be this way. Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. We'll take a truly global look at how to get us out of this mess.
