CADR should good (300-ish from my crude estimates) -- the fan to filter ratio is not ideal. Pros: Make it yourself, adapt design, proof of concept for DIY 3DP. Cons: Even with a 5" filter, filter constrained -- future designs should add more filter surface area to increase the CADR.

Artic P12 fans are cheap and very quiet, but any 120mm PC fan should work. Try to get quiet ones with fluid bearings. The wiring is pretty easy and there are internal tiedowns for cable ties.

The goal here is to empower schools to make and maintain their own air purifiers. To that end, we need mostly quiet solutions for classrooms that just run without having to think about whether it's too loud. Place against a wall, the angle maintains airflow in the back.

My idea was to make white tombstones in my yard and then use projection-mapping to change the text on the tombstone to cycle through your many ideas. This would be a powerful display.

Bernie Sanders was the first one to make long COVID a prominent issue, holding a special event on it in 2024.

The "return to normal" was for the economy. Lip service for precautions (quickly removed). Few warnings about variants, repeat infections, long COVID, or breakthrough infections (infections when vaccinated). Biden's health officials rarely said "long COVID" at all.

Of course, the story is tragic and early and I'm sure more details will emerge as it's investigated. But the wider trend is that due to widespread downplaying of long COVID, many people are noticing new chronic, health problems but misattributing the cause.

The missing story here is the man was physically ill. But instead of identifying it as long COVID (most likely explanation) he blamed the vaccine (due to misinformation). Many people have long COVID and don't realize it because both administrations downplayed it to keep the economy going.

Virtual Reality/Spatial Computing - Mostly works, but still not useful enough to become the next computing
Crypto - Problems it actually solves are more limited than hyped; much utility is speculation on future value
NFT's - Limited utility
Peer to Peer -Internet is P2P yet ended up very centralized

"Weird" just means "informed"

Came to say the same thing. You generally don't want important details needing color discrimination (color-blindness is more common than people think). And especially not THOSE colors.

Knowing your customer (banking; although not always effective). In any case, completely agree w/ the information problem. Worried that most solutions involve teaching an 80-year old to identify all the types of Medicare fraud from the 100 scam calls they receive daily.

A lot of the interventions in misinformation involve targeting the end user (e.g., prebunking), which I don't think scales well. 2) In complex networks, more effective solutions are often technological and (mostly) transparent to the end user. E.g., SSL (for e-commerce), STIR/SHAKEN (for phone).

Really liked this article. I am curious on your thoughts on 2 additional observations. 1) Although an informed citizenry is essential for democracy, few people can identify sophisticated (and often even crude) misinformation outside their area of expertise. Nobody can be a PhD in everything.

AI computation is still fairly expensive. Virtually all of these experiments lose money. If you want to protest companies shoving AI everywhere, there is an obvious way to do so ...

Also, a bad habit is sweeping away disconfirming evidence entirely due to a perceived flaw.

Worked with many tech engineers. They prefer quantitative data (large samples) and behavioral data (something observable and countable). Tend to discount expertise in other fields. They will often fixate on a particular theory and can be very subject to confirmation bias without being aware of it.

Of a very limited, under-powered study design, this is a pretty fabulous result.
