OK, so show us these really smart AI things. When I have to describe in 3 different ways to the AI bot that the Amazon order is wrong, and something a human would have picked up instantly....that does not sound 'really smart' to me.

Don't worry, you don't have to be honest with yourself here in your TDS afflicted echo chamber. Let your selective outrage flow and ignore that all politicians extensively lie, including the previous U.S. president who assured us that he wouldn't pardon his crackhead son, but did anyway.

Outbuildings might actually be the ideal application for this kind of thing, and there's some off-the-shelf stuff that can solve some parts of the problem. We built a greenhouse a while back that I set up to do as much passive temperature regulation as possible... south-facing lean-to design, with transparent polycarb walls but a metal insulated roof. Idea being that you maximize solar gain in winter when the sun is low, minimize it in summer, and the insulated roof helps retain some of that heat in winter. I also added a couple 50 gallon barrels filled with water and concrete pavers on the floor for thermal mass. Last piece is that you can pick up automatic window openers that use an expanding fluid to open the windows when it gets hot enough.

It's surprising how comfortable it stays in there pretty much year-round.

The overall semi-passive temperature control concept seems like something that deserves a lot more attention than it's gotten. I used to have a town home with no AC, but with a house fan that would blow air up through the attic... sounded like an airliner in the upstairs hallway when we turned it on. It was actually surprisingly effective, but to keep things comfortable in the summer we had to turn the house fan on at the right time in the evening, turn it off at the right time in the morning, open/close downstairs windows to draw in cool air, and then keeping the blinds closed on windows when the sun was on that side of the house.

It's the kind of thing that's annoying for humans to keep track of, but trivial to optimize with software. The hard part would be in having the actuated systems to control the vents, windows, blinds, and fans, and then software to integrate it all. Some of those things exist, but they're expensive so the ROI generally isn't there. A system like yours though basically fully automates the stuff I was doing with the house fan.

Have you ever crunched numbers on the savings? I would bet in terms of cost efficiency a simple system could pay for itself in a couple years, but in terms of energy efficiency I would think you're using at least an order of magnitude less energy than active cooling.

To be fair, we had plenty of that even back in the glory days... but the noise has stayed constant while the signal seems to have dropped off with most topics.

I'm curious, do you think the semi-passive cooling system will still be useful at beginning and end of summer, even if the night get too warm? Savings obviously aren't going to be as attractive as using it all through the summer, but I would hope there are still seasons where the system is worth running.
