Researchers in Hong Kong have come up with a new, elastic alloy that could provide an alternative to vapour compression technology, common in many heat pump devices today. The tech relies on an alloy of titanium and niobium to make a solid state heat pump, which the researchers say could enable highly efficient industrial-scale heat pumps in the future.
