Traditional cooling devices like air conditioners rely on refrigerants that can harmful to humans and the environment. Materials scientist Ichiro Takeuchi and his research group have developed a cooling device free of typical toxic refrigerants, instead relying on a physical property of certain metal alloys. These alloys produce heat when strained through stretching or compression, and absorb heat when that strain is released. This heat absorption produces a cooling effect that could be used for cleaner refrigeration in the future.
