Are you a Chinese Engineer?
No. But given the great success of far east engineers in taking our jobs, I am trying my best to learn from them the secrets of their success.

No entering another vendor's booth without their permission...
Bull. Fucking. Shit. 1) Trade shows are as much about vendors seeing each others' products as the public seeing them. 2) Trade shows are about showing things in public, and in public includes anyone.
The rest of your post aside from this specious trespassing claim, I agree with.
But not one that removes the tattoo without removing the skin.
Where was that requirement in the spec? I don't recall seeing it anywhere
The trouble with running 2.5kV is that it'd 'probably' be even more expensive as the power company would have to run you a line from the 'nearest' 2.5kV transformer, plus, do they really want to be running that voltage through a residential zone? It'd have to be insulated.
And run through sturdy conduit once it reached the house, preferably for the shortest most direct run possible. And you'd need some engineering work on the connectors, to avoid any potential for arcing across an air gap to anything the owner waved it near, metal stuff, fingers, etc. And even then, you'd probably want some super-sized GFCI-style cutoff for last-resort protection, and I don't have a clue how much that would cost.
You're probably looking at a hundred to two hundred a foot for the service run. Is that 100 feet or a mile?
I'd think it would have to be pretty close. They don't want to run 120/240 very far because of the resistive losses. But still, it would be expensive.
You're 'mostly' right'. You can have an 800 amp 240V service, I even found a box for it here [platt.com]. It's 'only' 4 modern home's worth.
Thing is, even the wire to carry 200A costs $4-$5 per foot, times 3 cables--just for wire. (And it's only that cheap because they use aluminum for it. Good god copper would probably cost $100 per foot just for the wire...)
But I wasn't thinking so much of the wire to the house. I was thinking of the wire between charger and car. 800A worth of wire would be enormously thick stiff and heavy, far too much so for the owner to pick it up and connect it to the car. But I suppose the charging station could have a transformer to kick the voltage way back up in order to get the power delivered through a cable that one person could actually pick up and connect. Of course now you're going through two (potentially [haha]) unnecessary transformers on the way to the car...
Pretty sure that with $20 and a trip to Home Depot I could create a tattoo removal cream
Say what you want about Wall Street - and I'll be right there to join in - but they do know bullshitters and bullshit.
Now THAT is bullshit!

Stealth subs aren't a new idea...
Well, yeah. ALL subs have been designed as "stealth" weapons. That was their entire reason for being. Of course the technologies have advanced over the decades...
Now granted those three walls do have quite a bit of lumber in them, being 1/2" tongue and grove boards covered in drywall.
You sure about that? I bet they're lath boards (no tongue, no groove), supporting plaster walls (not drywall). And that might be your problem. Typically, when people with plaster walls have wifi problems it's because their walls use metal mesh lath instead of wood strips, which seems not to be your case. But plaster is also substantially denser than drywall, so I suppose that alone could result in some attenuation.
Anyway, drywall started to replace plaster in the 1950s, so newer homes don't have these problems, and really do get good coverage from a single access point.
You'd need an 800 Amp service to feed one of these and have enough left over to run the rest of your house.
You're right about the watts, but no so much about the amps. 800 amps would require ridiculously thick/stiff/heavy/expensive cable--completely impractical. What you'd actually need would be 2.5KV (or 25KV) service direct to the charger. And again, just curious, but I wonder what the cost would be...
...Tell that to anyone with a house that is more than 400 sqft.... Wifi has a range of about 100 ft indoors
Which means the range covers over 30,000 sqft. Now of course your house is not perfectly round, and your access point won't be in the exact center. But there's still plenty of margin to cover a decent-sized house.
Instead, shouldn't we be asking whether coding is really the best way to build apps in the first place?
Management has been trying to find a different way since at least the 1970s, CASE tools, 4GLs, yadda yadda yadda. Yet, somehow, in the end if you want an app working, you have to specify it down to the level of a programming language.
3. How to approach problems in an organized fashion
DING! DING! DING! Especially teaching people to break problems into manageable chunks, and construct layered abstractions. (Even if it's only 2 layers--not enough to master complex programming, but still that's a huge jump for most people.)
CNG cars can be refueled in private garages without going out... though I'm pretty sure the apparatus for that is far more expensive than a standard wall socket.
Just out of curiosity, I wonder what the cost would be of installing a charger with enough wattage to "refill" at a comparable rate? Interesting thought experiment...
I mean, who else can use a station built into a private garage?
Yeah, but who can re-fill their gas tank in their garage at night without going out?
So the comparison is tricky...
...and then cut me...
And apparently several thousand people per year seriously enough to send them to the emergency room for treatment...
