No invention needed here. Natural sunlight does the job perfectly. Not only does sunlight kill pathogens, it's also very good at exposing all the political cockroaches.

no they didnt.

ill tell you straight up that shit has existed since at least i was a kid.

youd go into a hairdresser and they would have little toaster oven looking things with purple lights they would put scissors and combs in.

they already use the technology on aircraft.

ive fitted UV hoods to vents in restaurants which basically destroy anything that goes up through those.

Oh, please, this is NOT a new discovery

UV germs killing lamps have existed since when I was born

Since the "possible use" has been stomped upon by big media, now, they have to make a fuss over the "discovery"
