The problem is that while $3k sounds cheap to modern ears - it wasn't in 1936. That $3k house was solidly the province of the upper reaches of the middle class - the top 10-15%. Not to mention, those details you list weren't created by the $1/day laborers - they would have been done by skilled labor just as they are today.
You could also earn $1 a day and live with a decent roof over your head and have enough food to eat. These were "toy houses" in Miami for (rich) winter transients from the North, in the 1930s, those people would have a 1200 square foot house they could get away to when it was just too cold up North.
Appetites for opulence have expanded considerably since 1936, witness the top 0.5%:
Et non. What you have described is a conduit that is open on both ends, not a closed loop.
The ends are in a "black box" - the ground, what you can't see must be simple, indestructible, and there for exploitation, right? Remove water from black box, return water to black box - closed loop for closed minds.
Actually, you could bury a heat exchanger in the aquifer, but it wouldn't be as efficient as the system you are describing as "open loop", would be vastly more expensive to build, and likely more damaging to the environment as well...
I think nefarious individuals are afraid of motion sensor lights, and dogs, not that I have any, but they don't know that, and many of my neighbors do.
I do have some motion sensor IR cameras... all kinds of interesting creatures moving in the yard in the middle of the night, none on 2 legs yet.
Which really tells you what a $149 extended warranty is worth - $90 cash to the store, probably $50 cash to the insurance company, who probably spends $25 administering the program and taking profits. Average payout on a $149 extended warranty $25. Your odds are better in a Mafia run casino.
That makes no sense at all. A closed loop won't get rid of heat, just transport it. There must be a system which exchanges the heat out of the water to the environment. Maybe a radiator system, maybe a chiller, maybe an evaporative cooling system.
Or maybe it's not really a closed loop?
Step 1, pump up some groundwater.
Step 2, notice that it's pretty cool.
Step 3, feed cool water to your supercomputer to keep it cool.
Step 4, notice that you have an awful lot of excess water to deal with.
Step 5, drill another well some distance away and pump the warmer water back into the ground.
Et Voila': Closed loop.
The heat energy is being pumped into the groundwater. Groundwater is a fairly massive thermal sink. If every house in suburban Tampa tried to do this, the groundwater would heat up, but if you're a single user of a huge natural resource it appears as if you're not making any impact and "getting your energy for free."
I live in a very dark neighborhood... no streetlights within about a mile, and lots of trees (makes stargazing... challenging.) Unfortunately, some of the neighbors don't feel safe unless they leave lights running all night long. It's a very basic human trait: fear of the dark. We have less crime in my dark neighborhood than many nearby well-lit ones, but facts don't erase fear.
Two printed walls can enclose an arbitrary thickness of the insulation of your choice. With some refinement, the wall printer might learn some finish plaster skills...
This is assuming that a house's wall is a singular item, which is a silly thing to think. Walls contain space for insulation, space for water to drain, wiring, plumbing and HVAC space. Yes, we could build a shelter with this machine, but 3d printing a house would be like 3d printing a maker bot. It may look similar, but until you have the insides built, it won't function. There's also a big issue with reinforcing the concrete. The walls will be primarily in compression which is fine, but if you tried to create multiple levels, the floors in tension would quickly crack under their own weight.
I'm not saying that we'll never 3d print a house, but their proposal shows a lack of understanding of the basic premise.
You're referring to "Modern Western" houses, not too long ago, lots of people would have been thrilled to have walls, a roof, and maybe a door. Some places, the still would.
You could lay in fiber or electrical cable as the layers are being printed, but servicing it later would be... problematic.
Something larger like a flexible conduit might work, but as the conduit becomes a significant fraction of the size of the "bead", it will get tougher, and the junction boxes would likely require some "hands on" work to set, or a much more complex robot.
The construction companies are tied into the building licensing/standards agencies. See how easy it is to get a building permit and bank loan for a dome.
These people can help, a little, but lots of places just don't like the way domes look, so you'll be fighting that battle even though they will say it's about engineering analysis, etc.
I had one of those 1936 homes, constructed by the barely sober laborers for $1/day. When you've got that cheap labor, you can construct wood lathe to go under the browncoat and two layers of plaster, you can afford an oak plank floor with mahogany inlays, and you can make Art-Deco architectural sculpted walls with built in shelving, and you can sell the thing for less than $3,000.
Building codes are good in theory, but the aftermath of Hurricane Andrew proved that the law isn't always followed, in-fact at nearly every un-inspectable opportunity, corners are cut to increase profits.
Remodeled one of those houses once. The entire thing was designed to fit in a single rail car. The original builder had done a crappy job on the foundations but the house was still solid because the sections were bolted solidly together. As long as you keep a good roof on them it will last forever.
They have been "cost optimized" now, they're called "trailers" and usually closely associated with trash.
You can also buy "Exposure D" prefab modules that withstand 135mph winds (better than most custom built homes), but they aren't much cheaper than a custom built home, unless you also build the custom home to Exposure D...
They've done these prototype concrete printers for many years (sorry, no link handy, but I saw a video at least 5 years ago...)
If you don't mind really rough interior walls, they could be printed too, slap on some EMT and surface mount electrical receptacles, exposed plumbing and HVAC, and this can be "finished" in way less than 3 months. Insulation? Print two walls - concrete is cheap compared to labor.
If you want "finished" carpentry, or custom carved stonework, or other things that take time, that will... take time.
Include a big campaign contribution with your letter if you want to make sure it's not just thrown in the trash or just added to the pile.
That works best for 'invisible' issues... I think the best chance of killing PIPA is making it very very visible, so that "the pile" looks big enough to threaten re-election.
Furthermore, I think it's absolutely incredible that people could buy these miniature supercomputers (they're still on par with a 2010 PC computer) and expect them to run flawlessly for a decade. I mean, sure, electronics technology has come a long ways in the last 20 years, but you're talking about a device that is going to pump literally half a million cubic feet of air (10 years * 80cfm) through it, dust and all, and function guaranteed , without service for a decade. That's mind blowing.
Well, mine died due to cold solder joints, directly attributable to the RoHS solder. I'm all for reduction of lead in the environment, but RoHS really feels like a consumer electronics industry conspiracy to make devices fail just after the warranty expires.
I just hooked up a standard PC wireless keyboard... I got the Gyration for the extended RF range, but if you're sitting close to it, a $20 logitech will work with a PS3.
I was, however, pretty amazed at just how little I could do with the keyboard once it was hooked up. Same thing for the PS3 Eye.
I felt more like I bought and paid for a 4kt diamond, then woke up one day to find that it had been stolen in the night and replaced with a 3kt by the people I bought it from.
They forced a "contract of adhesion" onto me when I bought it, then revised the terms every couple of weeks, eventually giving themselves the right to reduce my 4kt to 3kt, or, if I didn't like that, I could opt out of the new terms and just keep a 1.5kt instead.
I think PS4 will need to be a total "reinvention" of the device - first thing they need to do is look at all the people who didn't buy PS3s and figure out how to appeal to them. Anybody who did buy a PS3 (myself included) is likely pissed off enough with them to avoid the PS4 at any price. I don't care to think about the hours I sunk into "OtherOS" getting it setup and working, or the hours I have spent waiting 10+ minutes for an "update" that's blocking me from accessing the features I've already bought, paid for, and was happily using the day before.
I bought the PS3 for the "cheap" BluRay drive, I thought I wanted the media center features, but a WDTV does that better for less money, I thought I wanted the games, and I do have 2 or 3 that at least somebody in the family likes once in awhile, but nothing new for a long time. The first generation was power hungry and mine had horribly LOUD fans, it died with the YLOD, after awhile we bought a slim to get access to the games and BluRay drive again, the slim's drive broke after a very short time, so we're just using the games on the hard drive and Netflix watch it now.
For me, console game machines are dead. Maybe I wasn't the target market, I had never owned a console gaming machine before, I always opted for the general purpose computer instead, starting with the Atari 800.

Even broadly, malls are not 'for public use'.
Tell that to my friends whose house was isolated by a freeway onramp system that was only built to service... wait for it... a shopping mall.
They were eventually offered "just compensation," at least compared to the after real-estate crash market prices.

Has anyone done a forensic analysis of the clay? Could it have come from Foxconn?
It's already been done, price was $9M:

I have three or four ways I use Google, none of them have the SOPA blackout - it's mostly themes that are not getting overridden.
Why is slashdot ignoring the blackout?
With so many links to questionable content, this illegal news source seems like a hive of crime.
Get it right, it's not "a hive of crime," it's "a wretched hive of scum and villany."
