There is a good reason everything in hospitals used to be plated or just made of copper for touching surfaces

There is absolutely nothing notable about covid not living on a surface after 3 hours. On the other hand, the whole "and E. coli bacteria" bit could actually be quite important.

Summary of TFA: "we added copper to nichrome stainless."

I also LOLed when they described stainless steel as easily machinable. Any machinist will tell you that shiat is infamous for being the exact opposite. It work hardens and galls like a mofo. There's a reason stainless is usually marked for 1/10 the SFM of aluminum and 1/3 the SFM of generic steel on machining charts.

I had a friend working on a vacuum system tell me he once made the mistake of casually threading two stainless pieces together until they were fingertight... And they galled and were impossible to unscrew and just like that, $400 of parts down the drain.

cretinbob: you can't kill something that isn't alive


True, but "covid-unviable-making stainless steel" just sounds awkward.

OTOH, since virii are just little protein boxes with a bio-program surprise inside, we could liken it to a computer program stored on some magnetic, optical or semiconductor medium.  What do we call it when we remove a program from such media?  "Delete" !

So I, for one, most decidedly welcome our new covid-deleting stainless steel countertops!
