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.

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

    R134 was the “safe” refrigerant to replace R-12 because R12 is 11000x more potent of a ghg than co2

    There are some new refrigeration units that use R600 but the vast majority of refrigerators are still R134

    R600 being a highly flammable gas (it’s butane) has slowed its rollout a lot. Hence why a solid state non volatile refrigerant is still a cool development
