Watch out! Generating CO2 in enclosed spaces might turn into a health hazard without monitoring it.

CO2 is also “heavy” and tends to sink, so watch out for pets as it could be deadly for them - https://en.wikipedia.org/wiki/Cave_of_Dogs

Have no expectation of finding a “magic pill” that (permanently) solves your problems.

Very interesting! Thank you for sharing your project!!

However, in terms of some of the benefits you mention in the “motivations”, bandwidth, energy efficiency and CO2 might weak points: after all your server (backend) stays on 24/7 and it does all the heavy lifting anyway, doesn’t it? So you are not really saving bandwidth/energy/CO2… (unless - of course - you cache in “time” and “space” and reuse the search results for queries of yours and of other users).

Is the “cloud” sustainable and scalable, in terms of energy and environmental demands?

Racism.

I wonder whether you meant “bidet shower” or “bidet” (meant as a stand-alone additional sanitary equipment for a toilet room).
