... Not something an investor is likely to do if there is no market. If they already have a patent, then this product must have been tested. Perhaps not in the air, but somewhere. Patents can't exist unless they are approved. Who would approve a patent for geoengineering if it isn't happening? That's My point. And believe Me, if I could walk through walls, I would show You and I would patent that shit!
The point I'm trying to get across is a patent does not mean the idea behind the patent is in use. It is just a record that someone has produced the patent and includes details to guard against someone coming up with the same idea. 'Idea' being the operative word.
