I am in no way a supporter of opening things back up in any way.
But I'd wager I am not alone in needing a positive outlet among all the horror. What was the tipping point was hearing the president of Purdue University's ramblings on how it is sacred duty to open back up and regurgitating misleading statistics (there are 10 things on campus that are more dangerous than COVID-19, the risk to young people is near zero so we can isolate the susceptible, etc) Oh and this doozy when confronted about what plan or metric they had for determining whether it was getting too unsafe, he was not going to publicly commit to numbers. (essentially they are going to wing it, nice!)
So I want to redirect that negative energy into constructive logic from a layman's perspective because there is information and reason out there right in front of our face that is being ignored.
So I will start on will things that we already have readily available or can be repurposed from other industries to make a hypothetical safe indoor space.
We know AC is a potential super spreader in enclosed spaces. I'd bet that is how Cuomo infected his wife despite strictly self isolating in his home. In the absence of expensive filtration, we need to remove massive amounts of air and deposit it on the ground in concentrated amounts that can easily be cleaned or severely diluted amounts.
I worry that ceiling fans would do more damage that good because it would force air down but probably also outward. So I think floor fans that suck air down and out would be the more ideal solution. And once air is sucked down, the flow needs to stay down as it is redirected away from occupied space.
Could fans be built into table tops that sucked air from people communicating with each other? Perhaps we could build a cylindrical inducting fan in the center of the table to further reduce risk at its base.
They use hanging plastic slats in lieu of doors in hospital quarantine areas, why not use them indoors? Perhaps we could even set them up in line at 6ft partitions. Or we can set them up along pathways and aisles in between tables.
You could probably do small conventions this way. Set up slats in between booths where less than 10 masked people could watch vendor presentations before moving on to the next slat divided booth.
We obviously cannot spray chlorine onto bare skin or clothing. But we can designate a clean room where chlorine is sprayed on "used" air removed from occupied rooms. It could even be a redundant system where it can catch it a second time before it leaves the building.
But a better solution is spending more time developing UV light. We need to know how much, what kind, and for how long. Because with the right numbers, we could set up UV to kill whatever infection lies in "used" air on its way out of the room. Those same cylindrical induction table fan's could kill COVID further down the table leg and hypothetically make the air clear without ever leaving the room.
What are your ideas to combat public indifference? It doesn't have to be safe indoor spaces, just observations on changing things overlooked in our drive to get back to "normal".
