asciilifeform was obsessed with the item as a boy, and went and... built. but unsurprisingly was unable to come up with the kilowatt spark gap horror that'd actually make circuit close even 1ce
asciilifeform: ( semiconducts and then shorts and welds solid at the juncture! hence the early radiotelegraph's little hammer that whacked the tube each time it went conductive )
asciilifeform: consider early age of radio, with 'coherer' -- tube of iron filings , nobody had any idea how worked until 1980s (!) when somebody bothered to look and found that yes feo2 semiconducts
asciilifeform: ( which is why icbm complex is just as essential 'petro tech' as the drill ! )
asciilifeform: re: petrowank : asciilifeform also not expert, but last i recall arabs were 'peaked' while ru ramping for 50+y and onwards; hence the pantsuit's perennial interest in picking up last reich's torch and 'spreading demoocracy' there
asciilifeform: mircea_popescu: afaik beekeeping is closest thing we've got to 'ant automation'
asciilifeform: mircea_popescu: for good chunk of later 1800s folx were using 'accidental' semiconductor ( ever built 'crystal radio' ? ) , but it sucked
asciilifeform: ( a la wootz -- i.e. 'we have nfi how this worx but here it is' )
asciilifeform: could've had transistor in 1700s-level, conceivably
asciilifeform: 1000+yrs of уравниловка (btw how do we say that in ro? i'd like to know) dun wear off so quickly.
asciilifeform: ( and not simply peasants, but serfs, i.e. land gets mortmain'd by master, so no accum )
asciilifeform: http://btcbase.org/log/2018-12-11#1879840 << i suspect that it prolly unpacks ok if seen through lens of 'wooden civ' peasant, where 'errybody is roughly same, working same shit soil, so oughta have ~same harvest'☝︎
asciilifeform: pretty hard to get a good cutting edge from plain sio2 ( try it some time ). with glass ( i.e. with na as well as si & o ) you get the requisite shear. so cuts.
asciilifeform: mircea_popescu: gotta nitpick : quartz ( plain old sio2 ) != obsidian. in the latter, the volcanic ash dun simply colour it black, but gives crystal lattice a shear plane ( so you get that delish cutting edge the stone age folx like )
