Your conversion took a wrong turn somewhere. BAC is just percentage, promille is parts per thousand. So to convert, multiply by ten. Making it 4,2 promille. Really shitfaced. Very potentially life threatening even if you are not driving.

A truly horrifying prospect.

Knowing all your players current stats, feats, and items is a pretty high bar for a casual DM.

But also, if some of your player's characters can make the roll and some can't, I'd say it feels worse to say off that bat, "Roll a WIS save, except you Phil, you fail." That will feel more like getting targeted than your build just not being suited to the current situation when you roll well and still fail.

Well, I can understand the feeling, but it's not true. Many of the states in between have a better ratio of relatively sensible people to fruitcakes than it looks like, but the fruitcakes have gerrymandered voting districts pretty severely. Which is a self reinforcing issue.

Radiant heat is great, and heat pumps absolutely can and should be used to supply the heat. Radiant cooling, while technically possible, has a lot of downfalls, forced air is your best bet there. The same heat pump can be used for both though, just need a valve to switch between different supply loops.

If you made money doing that, it probably would be illegal. You would certainly get sued, in any case.

USA had the same thing, "Cash for Clunkers". Some of the cars we were better off getting rid of. Some of them not, whether because they were rare or classic, or old but still more fuel efficient than a truck or SUV. Sure increased the average price of a used car though.

Of course. Those resources are just a much larger impact percentage wise on an appliance replaced every two years vs 25.

In this analogy, the AI uses books like a remix DJ would use bits and pieces of songs from different tracks to splice together their output. Except in the case of AI, it will be much harder to identify the original source.

More water and energy efficient to run, yes. If you have to replace them every couple of years the resources used to make new ones need to be included too though, and that will have a big impact on the comparison. That said, I have had a modern front load pair for at least 5 years now, no issues.
