@neroden I just did some quick math on this. Take a Very good CR box with 5 2” filters: 800 CFM. The average airspace of a Walmart: 4.25 million CF. For 1 air change per minute 5300 boxes. The next question we need to answer is how many exhalations is an infectious dose? So then we can fix a proper target for how many ACM would be needed.

@neroden It is really hard to find numbers on that as virus levels fluctuate and throat activities change things. I am thinking of the case of the jogger in China who infected 22 people (out of some 2300 he passed by). That suggests that an infectious dose can be on the order of one exhalation of air. And I’ve seen that hard breathing is about 10x more exhalation. So 10 exhalations calmly walking through store?

@neroden And it appears that people average 12-16 breaths per minutes. So, being in the presence of an infectious person for 30 seconds to 1 minute is likely an infectious dose (certainly not in all infections for the whole duration of the infectious period). So what level of air sanitation in air changes per minute would be the target?

@neroden I would be curious to see your math on 2.5 minutes if you feel like taking a stab at it.

@jalefkowit No, you are right; we just aren’t at “ overwhelming, oppressively obvious evidence” yet. People don’t learn by scientific evidence; they learn by experiential, emotional evidence.

@fcktheworld587 Denial fixes a great many problems. It is an irony of history that undeniable evidence often leaves the people who might have learned from it dead. @jalefkowit

@lightning @yuki so how do you assess the quality of the fake Romance language? Or 1000 of them? If it is to be challenge it needs to deliver the goods, right?

@yuki @lightning now one could take the basic vocabulary of say Vulgar Latin and put the grammar of Babylonian on it, or something truly bizarre that nobody would appreciate.

@yuki @lightning also, there are words, basic ones, in old English that can be broken down into descriptive units of meaning and translated using… Basque. People don’t much talk about that though. Too strange I suppose.

@yuki @lightning I’d wager that any programmatic interpolation of Icelandic and French would be hard pressed to deliver English in all its bizarre glory. English took a very different direction.

@yuki @lightning except it has the least of gallego, the language of your overgrown land of many lakes, Galicia. It is more the fever dream of the crown of Aragón 500 years past.

@yuki @lightning English, Latin, the Romances, the Germanics, but especially English, these all have a habit of swallowing foreign words, place names, whole, with no expectation that a name fit the entity it hangs on. Another way to express the world makes everything in it have a descriptive name built up from particles. Rebuild a romance in this fashion?

@futurebird when you move to shorter mortgages, the payment goes way up, much less affordable. This would stop sales, but housing prices do not go down because few people have the equity to sell for less and those who do choose to wait. Eventually the foreclosures start when people have to leave but can’t sell, but prices stay the same, because banks don’t want to lose money either. 2008 illustrated this. There are solutions…
