mircea_popescu: calculate
the maximum
thickness of rebar allowable if 1% strontium is radioactive.
mircea_popescu: if i were
teaching a nuclear physics class
the next assignment would be,
mircea_popescu: asciilifeform
the soviets had a recipe for warm concrete floor
jcpham: someone needs
to put his lights out
jcpham: mayweather gonna do it again
tonight?
jurov: we,,
there already are attepts for self-assembling chips
mircea_popescu: that';d be
the fucking end oif it, when i go
to cash and carry, buy
two sacks of nano particulate silicone cement
mircea_popescu: we don't have a very good model
to map hash
to
transistor count yet.
jurov: i'd prefer
to just stick
to
their 2016 projection
jurov: but
transistor cost is directly related and
there are many expesive chemicals irreducibly needed
mircea_popescu: the end of
the free market and silicon cartel cca 2003 is well visible on
that plot
mircea_popescu: make people pay now for benefits later, which
they believe in because it's
the founding myth of
their civilisation.
mircea_popescu: much like white folk's pensions,
the best scam in
the book
mircea_popescu: in a year 2x as good
tiles will be sold also at 500 also on a 5 year promise
mircea_popescu: so
today
the
tiles will be sold at 500 dollars and
the 5 year promise
mircea_popescu: anyway, you seem
to
think
the more hashing
the worse off bitcoin is.
mircea_popescu: because
that way
they end up paying 25% less over 5 years.
mircea_popescu: "every luser" = rich white folk who can afford
to pay 5x as much upfront.
mircea_popescu: you will get roughly half
the cost of your power usage back as bitcoin, i iamgine.
mircea_popescu: if you install it
today
that 38
to 72% money back reads more like 4500
to 95000%
mircea_popescu: or have high
tech heating doing 99.5% efficiency and 38
to 72% money back over a year, at 500 dollars per unit"
mircea_popescu: "you can either have low
tech heating doing 99% efficiency for 100 dollars per unit,
dub: price will level out
though or at least get more predictable
mircea_popescu: by
the
time asic
tiles are available bitcoins are 100k-1mn per anyway.
dub: diff will level out
though or at least get more predictable
mircea_popescu: "sorry you can't have asic heating because it interferences with
the weasels"
mircea_popescu: i don't see what diff it makes, outside of perhaps being
the avenue
through which govts will
try and limit
the practice if
they somehow decide
they want
that
mircea_popescu: a lightbulb even is mostly a heater rather
than a rf source.
mircea_popescu: this is visible
to
the nakled eye, but it doesn't come
to significant emission in
terms of energy
mod6: haha <3
turbo button
mircea_popescu: the only
thing is you will need special designed chips
to limit clock frequency so
they may be passively cooled.
mircea_popescu: such as you know,
the plant,
the lines,
the
transformers, etc.
mircea_popescu: and
that 100 dollar allowance is incredibly generous, seeing how it's equal
to everything power
takes.
mircea_popescu: now, for as long as 1th mines 100 dollars worth of bitcoin, it is perfectly economical
to heat with
the miner
tiles.
mircea_popescu: in
the power + hash assembly you have suppose 200 dollars cost per mjoule, and generate 1th worth of hash.
benkay: i don't
think we've drawn sufficiently rigorous boundaries around
the various systems
to
talk like
that, asciilifeform
mircea_popescu: let's do
the math for
this, shall we ? power generation costs, about $100 per mw, yielding electricity, which
transforms directly
to heat at ~$100 per mj.
benkay: ergo cali wind farms are frequently idling during
the nighttime
Apocalyptic: it used
to be profitable in France, cause local power co was forced
to buy back at a crazy rate by law
benkay: but again,
that personal bandwidth problem :(
benkay: there's also some return in housing fpgas by wind farms and burning electricity for
them
mircea_popescu: that aside, people still mine on fpgas, strictly because in
the winter it warms.
mircea_popescu: asciilifeform because
the marginal gain is not quite enough yet, and
they're noisy, clumsy and unwieldy.
benkay: although fpga arrays are how i'm going
to heat
the next office
benkay: market inefficiencies. i don't have bandwidth
to do everything myself.
benkay: in
that someone rounded up a pile of capital
to build absolutely sufficient boards and are now going
to sell
those boards as heaters
to building builders and renovators, recouping
their capital by capturing
the coins so generated
benkay: yes, let's do assume
that
benkay: in addition
to coinbases
there are also
txn fees
mircea_popescu: in
the not-so-distant future electric power, nuclear and solar, will be all
the power we ever use.
