> And you're going to need a good bit of engineering studies done before you start cutting that many holes in the floor.
You can Swiss-cheese a pan and deck concrete floor with core-drilled holes, the important thing is GPDR scanning before coring to avoid the pre- or post-tension cables embedded in the concrete.
> There's already enough plumbing in there for a whole office to shit when they get to the office.
A 20,000 sq ft office tower floor will usually have a single set of restrooms and a couple of kitchen sinks, maybe a dishwasher, plus a couple 6-gallon or instahot water heaters. If you subdivide that floor into a dozen units, that’s 12 showers, 12 washers, 12 dishwashers, 12 toilets, 24 sinks, and 12 water heaters.
The riser and drain pipes aren’t big enough to handle residential needs.
That's not how the 'black market' ones I've seen operate. And I've seen a lot from when I visited the circuit of underground artist-related events when I lived in chicago. They are shockingly common in areas with extremely high rents and an oversupply of unused commercial space.
They might subdivide it 12 ways, but there is one shared kitchen for a whole floor and maybe 2 toilets, 2 sinks and the residents are going to the laundromats. They tend to put the shared amenities on the ground floor as much as possible because it is easiest to expand them there. It beats being homeless by a long shot.
For reference, when I hauled water, we used about 60 gallons a week for a family, or about 0.05% utilization of a 3" drain pipe for a single family. You do not need much water in order to be way way better off than being homeless; 5/gal a day of non-potable water and you're pretty much in luxury comparatively and a shit-ton of people can be putting that down a 3" or even 2" drain pipe before it causes problems. A 3" pipe is the minimum that would be serving a typical floor of a warehouse, so plenty enough for a constantly used couple of shared bathrooms with a shared kitchen. Honestly even splitting it 12 ways could be overcome with some technical ingenuity (electric lock-outs to prevent more than a few in use at once, and AAVs to prevent needing a bunch of new vents).
These are all easily overcome problems for people utilizing an ounce of civil disobedience with regards to the code. And yes I have personally done all the design and plumbing and electric for multi-structure properties (though not the black market ones).

It didn’t work out so great in Oakland at the Ghost Ship, 36 people died in a similar arrangement.
Building code is written in blood, things are done a certain way for a reason. You may be morally or ethically against them but following code saves lives.
36 people dead is a rounding error compared to mortality from people on the streets due to lack of access to housing. Every time I bring up this topic, someone trots out the Ghost Ship like a broken record, ignoring what I said about the mortality rate of people on the streets because shit rolls downhill when people higher up the socio-economic pyramid go the next rung down in available housing. Bastiat has an excellent writing on this fallacious logic you use, titled "That Which is Seen, and That Which is Not Seen."
Not having housing didn't work out great for 700+ dead homeless people per year that are estimated to die of hypothermia.
The code inspectors have blood in their hands. You may be morally or ethically against bypassing the codes, but bypassing it can save lives.
Black market housing is done for a reason, a very good one, and one that saves lives. Fortunately where I live, I built a house without any inspections whatsoever, so none of the code psychopaths were even around to make their absurd case about the ghost ship, and that is the only reason why I was even able to afford to own a house.
> Europe couldn't kick Russia, a country with 10x lower GDP and a decrepit army, out of Ukraine; how could it hope to deny any land to the US?
This isn’t particularly well know, but Russia has had nuclear weapons since 1949. I suspect this is why European countries have not adopted a more aggressive posture towards Russia in Ukraine. For some odd reason, no nuclear powers have ever invaded each other or declared war on each other since nuclear weapons were invented, aside from some bitchy slapfights in Kashmir. NATO is a de facto nuclear power, with (3) of the member states being nuclear states.
This is my take on it as well. You can only know what it’s like to be yourself and communicating the qualia of being you is impossible to do with words. You can only ever know what it’s like to be you, so aphantasia cannot be confirmed or denied.
People that think they have aphantasia like talking about it because we like applying labels to ourselves and it makes them feel distinct. I’m sure this is not a popular opinion, but given the inability of knowing what it’s like to be someone else, it’s the only rational belief about aphantasia.
I get hyper-targeted ads trying to sell me electrical distribution equipment and air handling units because I run commercial electrical work (mostly mechanical equipment focused) and search for a lot of equipment part numbers. They’re on target, but ineffective.
None of the ads could ever be effective, I have my supply houses that I buy from and they don’t advertise online.
I do have a decent amount of buying power at work (single digit millions a year) but no internet ad from an electrical distributor is ever going to influence my purchasing decision.
Offices that use air handlers and VAVs also have narrow VAV zones along all perimeter windows. It’s for comfort, windows are where the most heat is lost/gained so heating or cooling those zones makes the space more comfortable for the people inside those areas.
That data center likely still uses liquid to liquid heat exchangers with a chilled water loop and cooling towers to reject heat outside, but I could be wrong. Piping refrigerant around a massive building costs way more than chilled water, same goes for filling up the system, glycol and water is cheaper than refrigerant.
Large solar sites are required to be able to provide reactive power as well as maintain a power factor of 0.95 to avoid all of the issues you mentioned.
> There are also factors like fault current handling that HN might think is trivial or to be glossed over, but without the ability to eat 10x+ rated load for a brief duration, faults on the grid cannot be addressed and the entire system would collapse into pointlessness.
I don’t understand what you are talking about here. I don’t work in the utility world, I sell and run commercial electrical work, but handling available fault current in my world is as simple as calculating it and providing overcurrent protection with a high enough AIC rating or current limiting fuses. I don’t see why the utility side would be any different.
The utility side has found that vaporising short circuits is a useful feature, as that includes e.g. twigs hitting a power line.
There are breakers, of course, but they react slowly enough that there will absolutely be a massive overdraw first. Then the breaker will open. Then, some small number of seconds later, it will automatically close.
It will attempt this two to four times before locking out, in case it just needs multiple bursts. It’s called “burning clear”, and it looks just as scary as you’d think… but it does work.
The lack of rotating mass in a solar site means the rest of the spinning mass of the generators needs to compensate to maintain frequency and voltage, right? So when clouds roll in and the solar field output drops quickly, it’s a challenge for the rest of the system to compensate since any other generator that spins will slow down much more slowly, giving the grid more time to react.
Also, I was not aware that inverters can only handle fault current that is 1.1x the nameplate capacity, that’s a big limitation. I can buy a 20A breaker with 200kaic, which is 10,000x higher than the breaker ampacity, which is extremely helpful for handling fault current.
Nobody drives sheet goods around in a pickup or a work van with any sort of regularity.
There are only two trades that use sheet goods: drywall and carpentry. Most of the time they’re getting dozens or hundreds of sheets delivered to a job site.
What are you going to do with (12) 32 sq ft pieces of sheet goods anyways, put up drywall in a half of a bedroom or reroof a quarter of a garage?
If you really want to do this, you’ll get a roof rack for hauling sheet goods.
