“The most powerful tool we have to reduce risk [of airborne viruses like SARS] is far-UV”
Fascinating description of how to build your own far-UV lamp — the light-based equivalent of a Corsi-Rosenthal box. Except that much quieter; more energy efficient; and best of all between 2 and 5 times as effective.
Love Joey Fox and love that this is at least an option that's being explored, but it just goes to show how far we are from "having the tools" when you see the lengths(and cost) required to do something like this at this stage.
It's a technology that I really hope continues to show effectiveness and matures into a legitimate option for everyone.

There are some off-the-shelf solutions but they do cost rather more, e.g.
The ones I’m interested in (Krypton Shield) apparently cost $2000 each. Frustratingly the company didn’t reply to my enquiry.
Nominally you can get them from Amazon, but they’re not for sale in CA — I gather perhaps because they haven’t been approved here <sigh>
Yeah I've been keeping my eye on it for a while now. At one point I really believed China was going to invest heavily into putting them everywhere which I was hoping would lead to more adoption and a lower price point. Obviously didn't happen.
If you do end up splurging for one yourself, keep in mind that from what I understand the bulbs will last ~4000 hours on average. So if you blasted them 10 hours a day you'd be replacing them about once a year.
@BE
Thank you for the heads up. It would be great if some country took the lead…
If I splurge for myself I suspect it would see very little use, at least in the foreseeable future — mainly if I ever need to for example let a contractor into the house for maintenance/repairs.
Friends though are also interested for a business setting — board meetings for a non-profit — which happen more regularly and are considerably more risky.
