RE:Today's NRExplain to me how you think this is superior than knr's Biocloud. Suppose a classroom with 30 students. One of them has covid. The sanitizer will kill the virus from the air but as long as the kid is there, covid is always in the air, infecting everyone. With the Biocloud you know there is someone positive with the high possibility no one else is infected, because it detects the particules before they get anyone infected. Because of the so tiny level it can detect before it infects people.
