RE:RE:RE:RE:Bio CloudI did see that already and there was not much info. I do know building control systems and the problem with reading air quality is getting the air into a sensor. It is not like a lab where we need many air room changes per hour, so the air is being pushed in a sense or you feel a sligh draft in a lab, so how do you get the virus into the sensor? Novel idea if it works.... This is why i still think you have to have people breathe into something.... just my thoughts ;-)
