A revolutionary crystal has been developed that could change the way refrigerators and air conditioners work, providing cool air without harming our planet. Traditionally, these appliances use liquids that contribute to global warming when they escape into the environment. However, researchers at Deakin University in Australia, led by Jenny Pringle, have created a more sustainable solution using “plastic crystals” that can adjust their structure under pressure.
When these plastic crystals experience pressure, their molecules align in a specific pattern, absorbing heat and cooling the surroundings as the pressure is released. This cooling effect occurs within a temperature range suitable for household refrigerators and freezers, from -37°C (-34.6°F) to 10°C (50°F).
Despite the promising results, the crystals still require high pressures to function effectively, which could be a challenge for practical application. However, experts like David Boldrin from the University of Glasgow see the potential for these materials to significantly reduce carbon emissions in the cooling industry. Bing Li, from the Chinese Academy of Sciences, raises concerns about the crystals’ long-term efficiency but remains optimistic about the technology’s future prospects.
