This is part of a broader trend towards more climate-friendly refrigerants, which is occurring in heat pumps, fridges / freezers and other appliances too.

And, as I found out, CERN's giant experiment is switching to CO2 as a refrigerant in some areas - because it is less damaging as a greenhouse gas than the refrigerants previously in use. The Large Hadron Collider is getting a little bit greener!

Gonna be in my head all day tho

Yeah this is the thing about a newsletter - you're on your own!! It's great! But also, you're on your own...

I have a writer friend who kindly subs all my stories before I publish them. (And when I can I return the favour for him). Maybe you could ask someone you know?

Industry sometimes uses even more sensitive detectors that can sense it at parts per billion.

Yes IR detectors can be used for that application.

Ah very interesting, I see. Hope it all goes well!

Yes - I meant, was it the current noise restrictions that meant you had to go into the garden? That's the main reason I've heard for that in the past.

Noise?
