Hong Kong, 26. Mai 2025 – Forscher der Hong Kong University of Science and Technology (HKUST) haben eine bahnbrechende elastische Legierung namens Ti??Nb?? entwickelt, die die Effizienz von Festkörper-Wärmepumpen drastisch steigert. Die Legierung erreicht eine 20-fach höhere reversible Temperaturänderung (?T) als herkömmliche Metalle und bietet eine umweltfreundliche Alternative zu energieintensiven Heiz- und Kühlsystemen, die auf fossilen Brennstoffen basieren.… Continue reading

A novel air conditioning technology can cool and heat significantly more energy-efficiently and sustainably than current methods. Elastocalorics requires no climate-damaging refrigerants, no oil, and no gas. Thin wires and sheets made of nickel-titanium transport heat simply by being deformed. The research team led by Professors Stefan Seelecke and Paul Motzki at Saarland University is now developing prototypes for... Continue reading

Solar power from the roof of a housing development flows into geothermal heat pumps and heats the houses, while surplus energy is stored and powers residents' electric cars: This is what the "EMSiQ – Cross-Sector Energy Management in Smart Existing Neighborhoods" project could look like. Ruhr University Bochum and the housing company Vonovia are jointly developing the concept and then implementing it in a 1950s housing development in Bochum... Continue reading
