mircea_popescu: decimation yeah heat pumps seem a lot better deal than any alternative, yet the least commonly used.
assbot: Ch E Page 301: Sustainable Energy - without the hot air | David MacKay ... ( http://bit.ly/1xMBmAj )
decimation: for the interested reader, some theory on heat pumps is here: http://www.withouthotair.com/cE/page_301.shtml
kakobrekla: mitsubishi is the shit as far as these heatpumps go
asciilifeform: and the junk is typically built to last about one decade. ☟︎
decimation: only a few factories manufacturer the equipment, and they usually only sell to 'licensed installers'
decimation: hvac is a particular kind of chumpatron in the usa
asciilifeform takes a very limited interest in exotic hvac tech, as he does not own his buildings, and never will
decimation: typically the most efficient ones are 'mini-split' systems
asciilifeform: and they are to be found where in usa? warren buffett's house ?
asciilifeform: but the fact that heat pump can only extract so much at a given external temp
asciilifeform: it wasn't the resistive heater
asciilifeform: (aftermarket controller. i take it from flat to flat)
asciilifeform: decimation: i had it configured to show precisely which mechanism was running at a given time
decimation: asciilifeform: the heat pump was probably turning on bigass resistor for 'emergency heat'
asciilifeform: natural gas is considerably cheaper, in this part of the world, than equiv. via heatpump.
decimation: they claim to heat (without resistive elements) down to 5 F
asciilifeform: for roughly similar type of wooden hovel
asciilifeform had heat pump in old flat, about 1/3 the size of new house (gas furnace there), actually cost more to run the heat pump
decimation: I have a friend who swears by the new mitsubishi air source heat pumps
decimation: the problem is that air source heat pumps can only heat down to a certain ambient temperature
asciilifeform: whether a heat pump is good economics or lunacy depends on the region
decimation: also considered purely in energy efficiency terms, a 'heat pump' is most efficient for heating, and can be 'run backwards' for cooling
mircea_popescu: i guess that'd have to be it.
asciilifeform: humidity is the real hell.
mircea_popescu: it doesn't have to be MUCH colder to extract heat.
mircea_popescu: asciilifeform condensation happens in acs too, what.
mircea_popescu: it'd prolly work better than air systems.
mircea_popescu: six months or a year down the road, we can continue this conversation in a better position.
decimation: part of the other reason 'forced air' heat is common in the us is because air conditioning is considered to be a requirement
mircea_popescu: bitcoinquestinos i could, but so far i'm not particulrly inclined. the logs are in the topic, peruse at your leisure.
mircea_popescu: (mostly for the co detector tho)
mircea_popescu: more expensive units come with their own batteries
mircea_popescu: asciilifeform no, but then again i never had a power outage. if they happened, ups would work fine.
decimation: yeah if i had to provide backup power for something like that, would use UPS
mircea_popescu: asciilifeform and since it runs maybe five times a day for a quarter of an hour, battery's quite feasible.
asciilifeform used to live in an early-1900s house with this type of furnace
decimation: this is very uncommon in the us, except for old homes
mircea_popescu: decimation you sort-of need it for the pump, but it's not so much.
mircea_popescu: my house in timisoara, the heating system held about a ton of water in the pipes and radiative elements. took about an hour to cool a coupla degrees.
decimation: yeah if all you need to do is heat boiler, then you don't need electricity
asciilifeform: bitcoinquestinos: about half the people here have www sites with human name, contact info, etc.
mircea_popescu: not better in any sense tho.
decimation: forced air is 'cheaper' to install
mircea_popescu: decimation a yes, turns out it is!
decimation: in the us gas heat is common, but typical large us house has a 'forced air' system that moves heated air around the house
mircea_popescu: decimation i have nfi what that is ? but no, either keep a pilot going, or w/e.
mircea_popescu: bitcoinquestinos mno. i mean, when it's decided that mtgox dies, it;s decided here.
bitcoinquestinos: mircea_popescu: What do you mean? Is this a place where people find the best way to spend their bitcoins so they can hold tighter?
mircea_popescu: decimation eu mostly heats on gas, these micro units that mostly don't need power. either because battery or ingenious.
decimation: because it could take days for the incompetents to fix the power lines in poor winter weather
decimation: yeah if you have a gas furnace, and you can run the blower, you can save your house water lines from freezing
asciilifeform: mircea_popescu: but what're they used for: typically stands between user and death from exposure. runs furnace blower/igniter in the cold months; a window ac unit in summer; fridge, a few lights, etc.
mircea_popescu: bitcoinquestinos this is where bitcoin happens.
mircea_popescu: decimation depending on the fridge. i think they make gen friendlier models now.
bitcoinquestinos: mircea_popescu: I know I'm asking what is the purpose of this IRC?
mircea_popescu: asciilifeform the generators ?
asciilifeform: mircea_popescu: they typically have surge rating of 5-7x
mircea_popescu: bitcoinquestinos irc is a way to talk to people
mircea_popescu: capacitive charge being what it is, the 2kw would serve for what exactly ?
mircea_popescu: asciilifeform> those who don't, typically own a small (5-10kW) genset on wheels << i have no idea what this would do. suppose a 2kw air conditioner unit, or fridge, or even washing machine.
bitcoinquestinos: thanks man, what is this IRC? I read about it in a blog post
cazalla: why the demand for s.qntr?
assbot: CZ 7.62x39 vs. Coleman Propane Tank - YouTube ... ( http://bit.ly/1IsnJ4C )
decimation: re: law enforcement deserts < https://www.youtube.com/watch?v=LU8sEJq3jR4 < gentlemen shooting various objects (including propane tank) in the middle of the freakin' desert
decimation: at any rate, perfectly common industrial tool
decimation: ah but those come sans generator
decimation: why propane? can be stored for a decade; doesn't leave nasty shit in the engine
decimation: asciilifeform: I have a small 2 kw job that runs on propane, to run essentials 'just in case'
decimation: re: 3mw genset < yeah that's basically a diesel-electric locomotive
asciilifeform: except for poor schmucks who live in flats, those sit out mains outages in their cars.
asciilifeform: those who don't, typically own a small (5-10kW) genset on wheels
decimation: re: generators < the power is so unreliable in many areas on the east coast that many folks have a propane or natural gas powered generator permanently installed at their house
asciilifeform: ben_vulpes: radiant or forced air << yard shed. portable furnace thing.
mircea_popescu: there you go, asciilifeform, re the orwellworm thread. he perfectly well knows what the problem is.
mircea_popescu: rk that he disapproves of that kind of conduct–on the contrary, there is a definite strain of sadism in him, over and above the brutality which a writer of that type has to have. Kipling is a jingo imperialist, he is morally insensitive and aesthetically disgusting. It is better to start by admitting that, and then to try to find out why it is that he survives while the refined people who have sniggered at him seem t
mircea_popescu: "It is no use pretending that Kipling's view of life, as a whole, can be accepted or even forgiven by any civilized person. It is no use claiming, for instance, that when Kipling describes a British soldier beating a 'nigger' with a cleaning rod in order to get money out of him, he is acting merely as a reporter and does not necessarily approve what he describes. There is not the slightest sign anywhere in Kipling's wo
mircea_popescu: "Kipling is in the peculiar position of having been a byword for fifty years. During five literary generations every enlightened person has despised him, and at the end of that time nine-tenths of those enlightened persons are forgotten and Kipling is in some sense still there."
asciilifeform goes off to check on roaring propane heater; if water bottle thawed, workshop is habitable
mircea_popescu: obviously a scavenger civilisation will hafta be built on top of the previous cities.
mircea_popescu: now that sort of thing is probably a lot iffier.
asciilifeform: to the point that the limiting factor is finding climate-controlled floor space for them
asciilifeform does not often have praise for usa, but cannot deny that it is a first-class graveyard for surplus golden toilet tech - e.g., machines like the 'tecan 200' (see ancient thread) originally costing 1/3 $mil can be had for ~5-10k usd, etc.
mircea_popescu: in fact argentina is about as close you can get to china without having to fuck azn looking women.
asciilifeform can picture this
mircea_popescu: if the chinese make it, it can be had here.
mircea_popescu: asciilifeform the thing is, argentina-chinese trade relations are about as close as us-canada
asciilifeform: but wanted to point to the difference between a ubiquitous piece of construction equipment (SOP for electric welders at large sites) and something like a 6-axis cnc mill
mircea_popescu: aha so same thing then
mircea_popescu: "could be had when you decide, on your own terms"
asciilifeform: we have those too. typically found at construction sites.
mircea_popescu: this is the important part here. not that "in principle could be had"
asciilifeform: normally only connected to hallway lights & elevators, though.
asciilifeform: quite a few office parks around here have gensets. through a quirk of bureaucracy, they were made mandatory at one point
mircea_popescu: not these days, notrly.
mircea_popescu: oh well then obv.,
asciilifeform lives outside the city limits of wash.d.c. proper
mircea_popescu: mebbe i am confused as to how things actually work thar.
asciilifeform: lol! everybody on the street (but me, apparently) owns a genset
mircea_popescu: if tomorrow your street loses power, you can't simply ordered a truck without wheels dropped in front of your property. for various pseudolegal and regtulatory reasons that essentrialy reduce to
