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.
I use my elbow. It is the same recommendation as to cough to your elbow. You do not touch with your elbow on yourself or others so it is generally safe.
Unfortunately not always practical due to poorly designed handles and lock mechanisms. I usually "sacrifice" my little finger for this when I have to use my hands, with the theory that I'm much less likely to put that finger in my mouth or eye etc.
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
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?
I guess my "I still don't care about cookies" add-on prevents the pop-ups, but one of the other add-ons prevents the video from playing. Or the site is just broken.
