ben_vulpes: made by a giant corporation in
the business of fabbing horrible shitboard boxes
Dimsler: i don't see
them smelt plastic and mould injecting domes
The20YearIRCloud: mircea_popescu: and if you had few/no
temperature swings it'd be fine
The20YearIRCloud: R value of
the air insullation isn't going
to be
that great, maybe 10
ben_vulpes: this has heat xfer implications
that you've not considered.
Dimsler: in africa
theres plenty of access
to clay
The20YearIRCloud: The minimum R value for wall insullation (not ceiling mind you) in
the US is now in
the area of 25-30
assbot: 4mm
Twin-Wall Corrugated Plastic 8' Wide - FarmTek
Dimsler: lol nobody is going
to live in
that.
Dimsler: refer
to
the restoration of Rome
Dimsler: its
the man power
that is unaffordable
The20YearIRCloud: Because
that dome would essentially be shelter, absolutely no protection from heat or cold
Dimsler: aggregates and building materials
to build proper shelter is cheap
ben_vulpes: mircea_popescu: i mean separation of panels? lifting of
the
thing?
Dimsler: are people going
to be living in
this shit?
ben_vulpes: JuliaTourianski_: you've not bothered
to read
the link, i gather.
JuliaTourianski_: +ben_vulpes
the point is
to easily build it. domes are much harder
mircea_popescu: JuliaTourianski_ well yes but
these aren't statements of
the same strength.
the problem being
that
the difference between
theory and practice is narrower in
theory
than it is in practice.
JuliaTourianski_: +mircea_popescu dont need one, but I'm sure i could. im very handy. wish i was more
techy isntead but hey.
The20YearIRCloud: I'm
teaching a class on basic mechanics/machines, and it's amazing how many people out
there don't understand how anything works
bounce: piffle. HIGH
TECHNOLOGY is
the way, I'm
telling you
bounce: well, nasa has a fix for
that
The20YearIRCloud: Compost
toilets are fine, any kind of containment system for sewage is just fine, but half
the world doesn't realize
that keeping your septic and your water in
the same place is a bad
thing
The20YearIRCloud: You can make a water filter for nothing
that filters 99.99% of all contaminants
The20YearIRCloud: Sure
they can, if
they know how
to do it, but it's always amazing how many people out
there don't understand a dang
thing
JuliaTourianski_: and
thers water filters for 100 bucks
that can filter virus and bacteria now
The20YearIRCloud: One of
the groups at my church goes
to Africa every few years
to
teach people how
to build basic water filters from sand/rocks/ect and when
they do it ,
they save a immense number of lives due
to cholera/disentery
The20YearIRCloud: Shelters are easy
to build, problem is lack of education/understanding, look at how many die in Africa due
to cholera
bounce: how's
that? what's
the fema paying in "intellectual property" licensing for its
trailers
then?
JuliaTourianski_: For hexayurts fabricated from four-by-eight foot sheets of foam or hexacomb cardboard and duct
tape,
the cost has been estimated at $1,000 each (compared
to $30,000 for a FEMA
trailer). Hexayurts fabricated from OSB and wooden blocks can cost as little as $250–300.
JuliaTourianski_: but it can be made out of
things other
than plywood for permanent housing
JuliaTourianski_: very cheap. every person in
the world can have one without enviro impact. +mircea_popescu
mircea_popescu: ok so basically
this is a cheap
temporary shelter solution ?
mircea_popescu: "Hello! If you're going
to Burning Man, have a great burn, and welcome
to our Financial
Times readers
too." ?
JuliaTourianski_: +mircea_popescu no, in relation
to how
tech will shape it, especially in
the "3rd world"
assbot: Engineers vs.Thugs:
the Power of Bitcoin, Cryptography &Tech - YouTube
JuliaTourianski_: +Duffer1 on
the entire picture of our future, and how engineering/tech will impact us politically
The20YearIRCloud: The big
thing is you don't have
to install high power lines, buy easements, hire helicopter crews
to fly over lines for obstructions and so on
The20YearIRCloud: These are
the ones
that use
the
thorium fluid,
they're between a
traditional reactor and a RTG
The20YearIRCloud: and it reduces
total grid costs which can be another 1-2c per KWH
that has
to be accounted for
JuliaTourianski_: I just did a cool interview with viney gupta on
the subject, editing now actually. first
time ive been hopeful in a while
mats_cd03: via selling commercial portable fission reactor designs
to
the rest of
the world at a nice markup
JuliaTourianski_: once
the energy issue is solved (housing, water filtration, food, medicine is all basically
there)
then maybe fuller will be proven right...and without reliance on gov infrastructure we can escape political systems altogether
mircea_popescu: the locals can get fucked, with
their hopes aspirations and expectations of "promises"
mircea_popescu: the criteria are, energy used
to erect, energy delivered after erection.
mats_cd03: its okay, .cn will solve
this in
three decades
mircea_popescu: well sure, not interesting,
that depends on your interests :p
bounce: dams apparently aren't worth
the costs long run, in
terms of environmental impact and failure
to deliver on
the improvement of life for
the locals promise
mircea_popescu: JuliaTourianski_ it's not really
that exponential. and
the price is a minute consideration,
the cost is
the main point.
bounce: so what's
the exponent? :-p
mats_cd03: everything
that can be dammed already has been, for
the most part.
JuliaTourianski_: solar is halving in price quite quickly and getting more and more powerful exponentially...wind is iffy.
take a lot
to maintain. costly. ugly. kills
the eagles :P
mircea_popescu: The20YearIRCloud hydro only works where you have a river ; wind only works where you have ...
the equivalent phenomenon, in
the air fluid.
The20YearIRCloud: Hydro is leaps and bounds better
than solar or wind, yet many environmentalists hate it
mats_cd03: lifetime eroi is higher
than nuclear iirc (~5x?)
The20YearIRCloud: And it gets alot of
talk
that isn't
true either. Solar just can't keep up with peak energy demands
bounce: time
to set up a research institute and write some billionaires for research funding,
then buy up all
the patents and
the research groups and make
them work
together
mats_cd03: solar works plenty, and it gets lots of
talk.
mircea_popescu: it could do without all
the idiotic derpage it's currently wrapped in of course.
The20YearIRCloud: Anyone
that
talks about photovoltaics and windmills as a answer
to anything should be immediately ignored
The20YearIRCloud: I'm not completely opposed
to renewables, but
the renewables
that actually work aren't
the ones
that anyone
talks about
The20YearIRCloud: What's $50b out of
total worldwide investments of 50
trillion?
mircea_popescu: bounce and not a bad way
to spend some money, at
that.
bounce: it's going
to need a lot of money
to beef up
the "renewable"
tech
tho
mircea_popescu: marketing firms
that know nobody's going
to jail for al gore's carbon credits mob deal.
assbot: BBC News - Rockefellers
to switch investments
to 'clean energy'
mircea_popescu: The20YearIRCloud funny how
that works
the same for me!

time i dive into renewable energy numbers I always find a pile of lies
