Dyson Snot Cannon

Dyson Snot Cannon Wearable SuperSpreader Event: (Unrolled.)

Ok here's a technical breakdown of why the "@Dyson Zone™ Air-Purifying Headphones" aka. the Snot Cannon aka. the Wearable SuperSpreader Event is such a staggeringly bad idea and a significant danger to public health if it is allowed to be sold. [...]

The Snot Cannon is based on a pre-2020 understanding of public health. Prior to 2020 there was limited attention paid to the concept of "source control". The source of the "bad air" was pollution- not us. The bad air had to be filtered coming in, surely not the other way?

During the last two years, we've learned the hard way that's exactly what has to happen. The air has to be filtered in both directions- even if we feel ok. Because we know that the asymptomatic spread of SARS-CoV-2 accounts for about half of all cases.

The problem is the Snot Cannon is worse than no-source control, it's far worse than no mask at all- because it uses high-powered fans directed at the wearer's nose & mouth which project exhaled aerosols outward. If you wanted to weaponize a virus host it would be perfect.

When we see someone hock a fat loogie onto the sidewalk we are understandably disgusted even by the 1-2ml of potentially infectious fluid produced. Yet, the average person expels 300-500ml of this fluid a day in the form of a fine mist- an aerosol. You can see it in cold weather.

Imagine spitting into a bottle for a day- and the next day, putting a spray nozzle on and casually spritzing it about wherever you go. This is terribly unsanitary, and the distance that aerosol-cloud travels is obviously something we want to minimize- not power assist.

Though, with the CDC now telling us that masks are optional and are only for protecting ourselves and not for reducing community transmission, these sorts of masks are well aligned with the zeitgeist of "fuck everybody who isn't me".

I'd buy a god damned space suit if I thought it would let me safely go to shows.
