No it said it does it without refrigerant.
Comment on A new cooling technology freezes food without warming the climate

Im sure that this doesn’t violate the laws of thermodynamics, but the headline makes it sound like this magics away the heat without using electricity or putting the heat anywhere.

The headline reads “A new cooling technology freezes food without warming the climate”. It doesnt mention the lack of (gaseous) refrigerent.
The thing about machines that make them bad for the environment in general is the fact that they use up energy, which is nowadays still mostly created in a process that also releases massive amounts of CO2.
Its unlikely that the environmental impact of the gaseous refrigerent is as big as the impact of the CO2 that is created to run the fridge over its lifetime. It makes sense then to assume this fridge doesnt use power, since right now thats the only way it could cool without heating up the planet.Im not saying this tech isnt interesting, but the headline is total BS

Old school refrigerants were absolutely horrendous ghg even modern ones are pretty bad with R134 being 1430x worse of a ghg than CO2
If we can reduce that, that’s good! And metals like titanium are recyclable so yes initially extracting them is bad but the full lifecycle isn’t as terrible

Modern refrigerants don’t use R134

It doesn’t use refrigerant, which is a pollutant.

No, but you can write a bullshit article that has very little bearing on reality.
Goes quadruple for its title.

Agreed. But you can cool without heating the planet. It doesn’t violate the laws of thermodynamics because it just uses a larger system - I.e. nocturnal radiative cooling.
