What you're describing sounds like a normal public toilet set up in my country

From the school restrooms I've seen depicted in various British TV shows, there isn't much physical difference. The only practical difference is that males, females, and various other genders might be washing hands in the same room at the same time. Now with a window to remind everyone that the sink area is a public space, and isn't to be used as a changing area.

That seems to be what they are going for here. Instead of using the space as one shared restroom with a hand washing station and 4 stalls, they are converting it into 4 private restrooms, with a shared hand washing station in a "public area" outside the restrooms.

So long as they build actual walls and use actual doors on the ~~stalls~~ "private restrooms", this isn't a completely terrible idea.

Can't give a general answer, but we can look to history. Consider the Castrati: removing the testicles before puberty prevented a boy's voice from changing, giving them a high singing voice in adulthood.

A few Nazis and KKK apologists convinced a shit-ton of marketers, influencers, Karens, and other predatory users to leave.

On balance, Nazis and Klukkers didn't make it any worse than it was.

The reality is that Xitter isn't actually any shittier than Twitter was. It's not any better, of course. But it's certainly not any worse.

It takes hours to days to start, stop, or change nuclear and coal generation rates. You can't just turn it on and off as needed. If you need coal or nuclear to meet overnight demand, you have to leave it running during the day as well. If you need 2MW of power overnight and 5MW during the day, you can only add 3MW of solar generation before you are putting too much power on the grid. If your solar puts out 5MW, you have to find out something to do with the extra 2MW that your nuclear plant needs to output continuously.

If you size your solar plants to produce 3MW in the middle of winter, then in summer they are putting out about 9MW. What can you do with the 6MW excess?

There is no single solution to manage every issue, but the single most important is "demand shaping". We need to reduce demands that can only be met with baseload generation. We need to move that demand to peak solar production times. We need to increase daytime demand to incentivize greater investment into solar.

Storage has to be a very distant second. Every 1 MW we time shift from night to day takes 2MW of load off the grid: 1MW to charge a storage plant, 1MW to discharge.

We need east/west transmission lines, shifting power from where the sun is up to where the sun is down. North America stretches over 4 hours of rotation. Californian solar plants are just waking up as East Coast plants peak.

We may need transmission lines over the poles, funneling power from where it can be generated to where it is needed.

We may need north/south intercontinental links across the equator, giving summer producers access to winter demand.

Number 2 is not inherently true. We can incentivize time-of-use, and push it to time-of-generation. Not with all loads, of course, but with a lot of them, and a lot of very heavy loads.

Our old nuclear/coal model pushes a lot of these loads overnight to reduce daytime demand and "level the curve". Steel mills and aluminum smelters often operate overnight and shutdown during the day, because that is what nuclear and coal needed.

With solar and wind becoming predominant, we need to reverse those overnight, "off peak" incentives, and push consumption to daytime hours.

The concept is known as "demand shaping". It is an underutilized method of matching production and consumption, but it is essential if solar and wind are to become our primary source of power.

A weed or roofing torch puts out about 500,000 BTUs. You need to think a little bigger.

These put out about 60 times as much, around 30 million BTUs, and a 30' flame. The pilot light on a hot air balloon burner is a 12-18" flame.

The burner cans weigh about 20 pounds, so a bit large to shoulder, but pretty easy to sling.

They burn liquid propane, not vapor, so you'll probably want a forklift tank rather than the usual 20# barbecue bottle.
