They already solved this in NYC and Chicago with extra hot radiators by windows.

The “spent breath” of the occupants of poorly ventilated homes contributed to 40% of the deaths in the country, he claimed, and often said “man’s own breath is his greatest enemy.” He would spend decades promoting the cause, designing ventilation schemes for buildings, penning a 1869 book, Leeds on Ventilation, and lecturing across the country. He explained his ideas with the aid of a “magic lantern” projector — think old-timey Powerpoint presentations. He’d show slides of a family in their drawing room, then add a slide showing red air coming out of the father’s mouth. The child crawling on the floor would eventually fall over. It “scared people to death,” Holohan says.

It's funny. The world is definitely a place we are willing to let 5 million people die. But we are definitely not allowed to have a single study where we have 1 definitely infected person stand in an air sealed room for 1 hour 6 feet away with someone not infected. Don't get me wrong, I have been wearing a blue 3M N95 mask since late April 2020 while around people - but a video of such a study showing definitive transmission would have shut down the entire mask hate early.

This agrees with my intuitive impression of everything I've read on Covid-19: that the primary transmission vector is through the being in unventilated or poorly ventilated enclosed spaces with an infected person for ~15 minutes or longer.

I definitely feel like neither governmental policies or people's individual precautions and behaviours quite reflect that reality.

There is also a problem of comfortable humidity levels. If you just have open windows, it seems like you will have very dry air.

There are modern solutions for air exchanges that do retain some of the heat and moisture while allowing for fresh air to ventilate the indoor space.

I would volunteer. It turns out that I have COVID right now, giving me a mild headache, nasal congestion, and a persistent cough---annoying, but not more than that. I would have gladly volunteered for this level of mild discomfort in order to advance the cause of science. Wouldn't even be hard.

Like the mountain of evidence (videos, photos, scientific proof, testimony from people who have actually gone up and seen it) has shut up the flat earth community.

There have been human challenge studies for covid, and people did volunteer. It would have likely been possible to get volunteers for the type of study the grandparent comment describes.

A potentially fantastic outcome from all this is that many more public and private spaces will be designed and retrofitted with very good ventilation.

Beyond curbing the spread of natural airborne diseases, it also may decrease the attack vector in our societies for airborne bio-terrorism/warfare.

And even beyond all that, we're becoming increasingly aware of how important clean air is for our overall health even without the risk of pathogens.
