Ozone: A powerful weapon to combat COVID-19 outbreak

> make shift mask steriliser.

was planning on that, too.  Until then, we're going to use the o3 generators to decontaminate masks, money from atm, etc.

The smarthome stuff is coming in handy for adapting quarantine areas and touchless control.

mine has not been delivered, and now the price has doubled.
Just been emailed to say its out of stock.

I just ordered the home model.

Home air filter unit: UV, HEPA, electro static and other filters all at once.  With ozone on demand.  While they can't promise this will kill coronavirus it's still kinda the Big Burrito of filters having UV and all.  Video worth watching.

Note: I've ordered a couple of reconditioned vacuums from this company and was pleased.

You can generate ozone with an HV spark coil, i had to stop using them for HV experiments due to the ozone generation but if your using it to zap a room then they are great for it and very cheap, or free at car scraps.

The 2 large-size ozone generators are working out pretty well. I just decontaminated a large shipment (20+ large, heavy boxes) of medical supplies along with some assorted Walmart online groceries we picked up.  I spread them out in the garage, sprayed them with Star San disinfectant, then ozoned them for an hour with both machines.

I just got a notification that my UV lamp has shipped. Maybe it'll get here. In one piece.

I bought walkie-talkies, just in case.

RC, your garage is going to be the most sanitary place in the county!  But it's a wise precaution all things considered.

> walkie-talkies

Can't hurt.

Sounds a simple robot to build to, except for the bit:

Meanwhile plant closures and other restrictions to curb coronavirus, have hampered getting parts. "The lack of one single component, [and] we cannot build a thing," adds Mr Guan, though he notes things have improved in the last couple of weeks, the situation has improved.

"There are not many good things to say about epidemics," says Professor Kolmus, but it has forced industry "to find new solutions".

TL;DR: UV good, Microwave bad.

'This study evaluated five decontamination methods [ultraviolet germicidal irradiation (UVGI), ethylene oxide, vaporized hydrogen peroxide (VHP), microwave oven irradiation, and bleach] using nine models of NIOSH-certified respirators (three models each of N95 FFRs, surgical N95 respirators, and P100 FFRs)....

...microwave oven irradiation and bleach decontamination methods investigated in this study were determined to be the least desirable among the five methods tested for consideration in future studies. UVGI, EtO, and VHP were found to be the most promising decontamination methods'

>UV good

15 mins each side with a 40w bulb seems like an awful long time.

>long time

Agree. 

Just got mine (25w). NOT broken!

Does HEAT kill it?

[rcjordan]

 research has shown that a related coronavirus that causes Sars could be killed by temperatures above 56°C or 132°F (hotter than even a bath scalding enough to cause injury) at a rate of about 10,000 viral particles every 15 minutes.
