The first ever machine that cools air using ‘muscles’ made of nickel-titanium. Felix Welsch and Susanne Marie Kirsch helped to develop the cooling system as part of their doctoral research projects. The new type of energy efficient, ecologically sustainable cooling technology that does not require the use of climate-damaging refrigerants is currently being developed by Professor Stefan Seelecke and his team at Saarland University.
