I am curious to know what positive impact ozone has on pathogens and specifically CV19. The use of tunnels saturated with o3 to walk through but limiting inhalation of o3.

What do you think?

A tunnel f full of ozone is a rather dangerous idea.
It's explosive, and it would probably set your clothes/ hair on fire.

If you dilute it in air things get less bad but:
It would generally take longer to diffuse through clothing than you can hold your breath.
It wouldn't achieve anything you couldn't do much more simply with a shower.

That's fairly impressive. And ozone is blue, so the gas stream used there is mainly air with a little ozone in it.

Ooooaaa  Rather corrosive!

You can buy low powered electrical Ozone and or UV-C generators to disinfect a space from microbes including viruses, bacteria, mould, invisble mites etc.  I'll make sure that rubber things and electricals are removed before doing that.
