The magical reindeer nose

Every schoolchild knows about Rudolph the Reindeer and his magic red nose. But Rudolph’s real-life counterparts really do have a magic nose. The colder it is, the better it is in keeping the animals warm and hydrated.

Speed warning system saves lives and reduces emissions

Universal adoption of the ISA speed warning system in Norway could reduce both the average speed of vehicles and their emissions, concludes a recent SINTEF report. Lower speeds also lead to fewer fatalities and serious injuries on the roads.

Energy savings in shopping centres

Shopping centres are major energy consumers with significant opportunities for savings. Researchers are currently checking the impact of savings made on lighting and air-conditioning at the City Syd centre in Trondheim.

This map shows the changing US CO2 footprint around the world between 1970 and 2008. Red hotspots illustrated where the US carbon footprint has increased, and in blue, decreased. The carbon footprint has gone down in some parts of the US, UK, and other places in Africa and Eastern Europe, while new emissions hotspots have emerged in growing US cities, Mexico, Europe, and throughout Asia.

Global hot spot maps link consumers with impacts

A new model creates global hot spot maps to illuminate how what we buy pollutes the planet and where. The idea is to help governments, industries and individuals target areas for cleanup.

One can never guarantee that the use of man-made gases in cooling installations will not result in unexpected environmental problems, according to the authors of this article. They recommend using nature's own ingredients instead. Photo: Bjørn Rørslett / Samfoto

Green cooling with CO2

Man-made refrigeration gases threaten the Earth’s climate. The use of natural compounds like CO2 is an effective counter-measure.

Researching the dark side of microplastics

Minute particles of plastic, called microplastics, are everywhere. An international research team is now about to investigate how toxic microplastics are to marine animals such as plankton, crabs and fish, and to find out if such plastics accumulate in the food chain.

Trapping the sun’s energy—in a box

Planning on cooking something at your hut? Today, you still need a gas stove to do so. But soon, stoves and ovens containing rechargeable heat batteries may be readily available for any cabin or home.

Helping today’s power companies anticipate tomorrow

It’s not easy for big, profitable companies to respond to huge technological changes. One NTNU researcher hopes to help Norway’s electric power industry cope with the market challenges from renewable energy and changed consumer behaviour.

Using EV tyres to counter traffic noise

Research shows that fitting tyres with very low rolling resistance, combined with the right road surfacing, can provide just as much noise reduction as traditional noise barriers.

Freezing plants to predict the fate of the Arctic

Global warming means much warmer winters in the Arctic, with more rain and icing. Researchers are working to understand what that will do to plants that have evolved to overwinter under a thick blanket of snow.

Keeping Arctic villages, infrastructure from falling into the sea

The Arctic is set to be a 21st century boomtown, as summer sea ice melts away, opening the area to increased trans-Arctic shipping and oil and gas development. A new understanding of Arctic coastal erosion offers clues to how to best protect the docks and other infrastructure this development will bring.

Hacking Trondheim to cut greenhouse gas emissions

NTNU and Norway’s technological capital—Trondheim—hosted a Climathon to give the city the tools it needs to make ambitious greenhouse gas cuts. The results might be helpful to other cities around the globe that face the same problem.

Food waste recycling not always the best idea

With Norway as a case study, a first-ever effort to quantify the benefits of recycling food waste versus preventing it shows prevention is the best policy. But Norway continues to invest significant funds in biogas facilities for food waste recycling.
