Heat pump can last 10 000 years

Researchers now are testing an entirely new heat pump. While those we use today last ten to twenty years, the new one will last almost forever.
The new heat pump consists of many miniature heat pumps as small as one cubic millimetre. To heat a house one needs several thousand of them. They are put together into larger units that can be tall and thin or short and wide.
The most important advantages of the new heat pump is that you can regulate its size and form and that it is more durable than heat pumps are today. It is also more environmentally friendly, Doctor of Physics Jan Kåre Bording says, who is Chief Engineer at the University of Stavanger in Norway.
