How cool is this? Nokia networks will warm Finnish houses. No more woodchopping. Sadly.

Finnish firm Nokia develops liquid-cooling technology to transform the
way your cell phone works

Our cell phones are reliant on a network of base stations to function properly.
These base stations are usually cooled using fans, but this could be
about to change.

The technology that keeps smartphones working is going liquid-cooled.

It may come as a surprise to find out that these pocket-sized devices
that can take photos, browse the internet and make calls are dependent
on networks of "base stations."

These base stations use antennas to send and receive radio waves. This
is important because, without the flow of radio waves, mobile
communications wouldn't work.

Fan systems are usually used to keep base stations cool, but in
Finland technology business Nokia has developed a station that is
cooled using liquid instead.

"Traditionally, base stations have been cooled by air," Nokia
Networks' Harry Kuosa told CNBC's Sustainable Energy. "This Nokia
innovation is now using liquid as a coolant," Kuosa added, explaining
that liquids were more effective than air at transferring heat from a
base station.

This, Kuosa explained, meant that cooling systems such as air
conditioning and fan units were not required, cutting energy
consumption by about 30 percent and carbon dioxide emissions by 80
percent.

In December 2018 Nokia announced that, together with businesses Elisa
and Efore, it had "commercially deployed a liquid-cooled base station"
in a Helsinki apartment building.

Nokia said that heat from the base station had been redirected in
order to heat the building, helping to cut energy costs in the
process.

Looking at the bigger picture, connected and smart devices could have
a big role to play in the future of energy efficiency.

"I think the first thing that we're going to see is virtual reality
glasses," Steve Evans, director of research in industrial
sustainability at the University of Cambridge's Institute of
Manufacturing, told CNBC.

"Instead of your children using them to play games… we're going to be
able to look in our factories and see energy flowing everywhere," he
added. "We'll know if that energy is being used to add value… and if
that energy is not adding value, we have to do something about it.
