Scientists say CO2-neutral cooling technology could keep cool world, but it’s not yet here
Scientists at Columbia University have found a way to reduce the amount of heat generated by CO2 in a device known as cryo-cooling, even as they are working to reduce it further.
The researchers say that the new cooling technology can be used to cool down computers, cars, refrigerators and other items, in part by lowering the amount and type of CO2 that gets into the body.
The cryo process, first developed by researchers at Princeton University in the 1960s, involves using cold liquids to push carbon dioxide atoms into a state of suspended animation.
The researchers have now demonstrated that a small amount of this process can be applied to cooling a computer, which they have shown is cooled by nearly 90 percent.
In their study, published today in Nature Communications, the scientists found that the technology can cool a device by about two-thirds.
The device also reduces the amount the CO2 gets in the body, the team said.
The technology has long been used to lower the amount CO2 particles get into the bloodstream, but is usually used as a cooling device for medical devices, refrigeration systems and other devices that need to cool rapidly.
The cooling method could also be used for other devices, including the power grid, heat pumps, solar panels, energy storage, heat pump systems and many other types of energy sources, the researchers said.
It is not yet known whether the technology could be used in other applications.
