An interesting take. There is also brass and coppers that self-sanitize, albeit more slowly: https://pmc.ncbi.nlm.nih.gov/articles/PMC11279221/

Sounds like a problem not worth solving? In my wework the handles get wiped down as per the cleanign protocol. Takes what, a second? The costs are marginal.

What about bathroom doors that are touched constantly?
▲vimda 1 hour ago
I suppose a second every few hours over dozens of doors adds up. And this has the benefit of being continual, so you don't get build up between cleans.

I'm sceptical myself that the tiny generator they have could produce enough energy, and that the coating they have won't be more of a hassle, but the idea is reasonable

How about silver plating?

Pure copper would be preferable, but brass is certainly much better than other practical options like steel. But preferably solid brass as brass-coated-steel doesn't work as well.

OTOH, cheap or antique alloys may have lead, so....

The TiO2 will likely rub off and need regular replenishment. Also, the alternative here, sensor-operated or button-operated automatic doors are already widely used. I wonder who this is meant for?
▲vimda 1 hour ago
This is probably easier to install or retrofit than an automatic door, seeing as it self powers

What makes you think so? One of the section titles says "Your inspiration" (rather than "Our inspiration"), which sounds like ChatGPT was writing to them. That wasn't around in 2019.

see the url, dysonaward ... so probably the site/judges asking/interviewing the inventor of this product.

Why not just use brass? Seems like a solution in search of a problem.
