Imaging if this technology could cool a data centre.

Edit: I was not involved in this project. You are wasting your time asking me questions.

But past cooling devices have not had enough cooling power for commercial use. The HKUST team developed a device that uses a new type of solid refrigerant, a nickel-titanium alloy with a higher nickel ratio. They also use calcium chloride as the working fluid that transfers heat away for cooling. Their design connects multiple alloy tubes together for a cascading effect that amplifies cooling.

In outdoor tests, the desktop device cools a surface down from 24°C to -12°C, and froze water in two hours. Sun Qingping, the mechanical and aerospace engineering professor who led the work, said in a press release that the researchers plan to increase the system’s efficiency and make it more cost-effectiveness by using advanced shape memory alloy materials and trying different system designs.

Cool.

Er, so to speak.

Finally, someone else in this thread that sees the potential.
