Real solutions for power congestion

We need more electricity, and the power grid must be expanded significantly. But how much and how quickly? This is how “monster masts” and expensive power expansion can be postponed.

‘Bio-batteries’ enable us to store solar and wind energy

Up until now it has been a challenge to store the energy we generate when the sun is shining and the wind is blowing. But researchers at a laboratory in Trondheim in Norway have succeeded in doing just this – and entirely without any form of advanced battery technology.

Running fuel cells on bacteria

Researchers in Trondheim have succeeded in getting bacteria to power a fuel cell. The “fuel” used is wastewater, and the products of the process are pure water droplets and electricity.
