How do we go from waste heat to electrical power, the turbine edition
Research on a certain turbine in a cycle that convert heat into electrical power, may in time contribute to developing cost-effective turbines. This is a stepping stone in increasing the return on renewable energy sources. My research concerns a certain component in a cycle that…
Contribute to research on furniture and sustainability
Did you know that an average Norwegian bought 28 kg of furniture in 1988, and as much as 74 kg in 2015?* Participate in our survey so we can understand more of how furniture is bought and used. This increase of purchase of furniture is…
Hot hotels in cold climates: reducing energy consumption with CO2 heat pumps
We’ve studied 140 hotels in Norway and Sweden, and found that CO2 heat pumps in hotels can reduce thermal energy consumption by about 60%. The hotel sector features high energy consumption, which contributes to the global warming effect. Our latest work presents a study of…

How is it to be a PhD student at NTNU during the corona situation? Cristina Maria Iordan describes her new work days from home, since the university campus closed. Who am I? My name is Cristina Maria Iordan and I am originally from Bucharest, Romania,…
Removing sticky droplets and making super repellent surfaces
NTNU research has come closer to making a surface that is self-cleaning even when there is strong humidity. To achieve this, we have combined pyramidical structures with nanowire structures in the nano lab.
Save money and the environment with smart heating controls
In order to stay warm, we usually require a certain indoor temperature all year around. This can get expensive in cold countries like Norway, not only for the household economy, but also for the environment. However, this might change with new, smart controls of heating…
Keeping cool during extreme heat
To fix a cooling problem in for example electronic devices, we have experimented with a carpet of nano-wires. Guess what, it works. There are situations where even when you spray a very hot surface with water to cool it, it will not work. This extremely hot…
Towards higher energy efficiency in the power and process industry
When you are boiling water for your coffee in the morning, you are observing how energy is wasted. Water is boiling at 100oC, but the surface of the kettle might be about 150oC. This waste of energy is because the heat transfer from the wall…
Is opening windows the best way to ventilate a building?
That’s a question architects and engineers don’t manage to agree on!
