Dyson identifies problems and then markets things that are targeted toward solving the problem. Not that actually solve the problem.

There’s more money in the search than the find.

People are concerned about air quality and n95 and higher respirators are ugly and uncomfortable and don’t signal wealth. The Dyson zone costs $1000 so people who don’t like air pollution, have money, and don’t know what to do now have something.

That being said, I would absolutely buy a stillsuit if it even did 1% of what a real stillsuit does.

In Neal Stephenson’s recent novel, Termination Shock, he writes about “earth suites” that people use to help mitigate heat and sun from climate change. I assume this is based on something available or hacked together so I’m on the lookout for a stillsuit.
