What is the news about?

As you use computers, as you’re surfing the web, especially in large data centres, it generates a lot of heat. And right now, that heat is wasted. It actually just gets pulled away and goes out through the chimneys, etc. Well, our scientists are putting small channels actually into the chips that do the computing, taking that heat back and using heat pump technology to then heat a building or even cool a building. So the energy will be reclaimed. So computing will become a lot more energy efficient.

People who live in polluted cities can see the grit and dirt produced from vehicle engines but some of the most damaging emissions are only now starting to be understood. They’re ultrafine particles, way too small to be seen. Hundreds of them, placed side by side, match the width of a human hair. They are primarily produced by combustion in diesel engines.
