Controlling problem ice — by cracking it

Most efforts to control ice build-up on structures like wind turbines and solar cells involve creating a surface that repels water. But Norwegian researchers have engineered a different approach that allows ice to form on a surface, but then causes it to crack off.

Wind turbine builders put theory into practice

Engineering students at the Norwegian University of Science and Technology (NTNU) are learning about more than just theory. A competition to build the best wind turbine also gives them the chance to put their practical skills to the test.

Havørnas største trussel i dag er roterende vindturbinblader.

Five kilometres between life and death

DNA profiles of the sea eagle population from a large island in mid-Norway are providing new and useful information as to how the birds avoid being killed by wind turbines.
