I'm personally pretty excited about far-UVC [1], thought it seems pretty hard (read: expensive) to achieve in practice. Compared to regular UVC, far-UVC is safe for human exposure. I have a prototype lamp at my place and when it's on, you can clearly tell that the air gets better. It's like an air purifier but it can also kill viruses and bacterias on surfaces. I doubt it'll get massive adoption due to covid but who knows, maybe by the next pandemic we'll be ready. :) [1] https://www.ted.com/talks/david_brenner_a_new_weapon_in_the_fight_against_superbugs https://www.ted.com/talks/david_brenner_a_new_weapon_in_the_...
