Questions:

How are we harvesting and refining N2 from the ambient air?

What equipment are we doing this with?

How much does that cost? To acquire, and to run?

How much heat is generated when you pull nitrogen out of the air?

… if you can answer those questions practically and affordably…

Well now … is this nitrogen more valuable as a personal coolant, or as an input for fertilizers or other various specialized industry/tech processes?
