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.
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.
Norway ought to put more effort into building floating wind turbines in the ocean, says Professor Lars Sætran at the Norwegian University of Science and Technology (NTNU).
