Silver-coated door-handles and hangers as an alternative, or
no handles at all --> automated door opening on body mass pressure (smart doorway rug) or movement sensor

I like the idea of creating a map for speed-shopping through the store. The Walmart app can store a list of items you want to buy. As and when you think of one, you add it there. The app will suggest brands and you can compare the prices and other details and add the items you want. Based on the list, the app will give you the directions that you need to follow inside the store for speedy shopping. So, you will have the directions even before you enter the store.

I like the ideas!

I love to try clothes and that's the only way how I am going to buy something, but I think the germs stick to the clothes the same rate as to the hangers and the racks. Since racks and hangers are usually made from steel, wood, or plastic, they stay greasy after every human usage and therefore, offer nice moist surfaces for bacteria growth or virus survival. But clothes do the same and are, in my opinion, offering the same as the hangers. Reducing the size of the hanger surface could help, but in these pandemic times, I would rather invest money in designing more precise body measuring algorithms and tailored clothes industry that could be used from the safety of your home.

Meal consultants could really become an important job. But wouldn't be easier if a person who compares prices, creates a list, give advice and creates a fast-shopping plan, also go to the shopping, too? It sounds like a low-budget maid job, right? Like uber-maids. They could be rated on how fast they are, how much money they save or how is the quality of the food they find.

I agree with Darko Savic concerning the door handles and other heated surfaces. It could be a bit scary (I can already think of a horror movie inspired by this feature 😂), but if you implement a safety feature, something like a door handle disappearing while not cooled could be useful. The disinfectants or maybe even an ultrasound (https://news.psu.edu/story/187690/2002/12/11/ultrasound-potentially-safe-effective-way-kill-bacteria) could be a nice alternative.

One alternative would be self-dispensing disinfectant sprayers that work much like car windscreen washer nozzles. The nozzles would be directed at the frequently touched surface areas. All sprayers in a room and wouldn't go off at the same time to minimize the amount of disinfectant vapor in the air. The disinfectant container would be hooked up to the internet and would "call home" when the level of disinfectant gets low and needs topping up.

One thing that comes to mind is that some bacteria can survive high temperatures. For example, water heaters have to go above 60 C / 160 F to kill legionella.

According to this paper https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7361064/ In order to kill COVID‐19, the objects would need to be heated for:

3 minutes at temperature above 75°C (160°F).
5 minutes for temperatures above 65°C (149°F).
20 minutes for temperatures above 60°C (140°F).

Would people (parents with children) complain if they touch a handle that is being heated at that time?
