07:56 < hprmbridge> Eli> Just get a second liver bro
08:39 < fenn> 50 bar is kind of annoyingly high, like i don't expect you could freeze waste bottles in ice and then expect them to not implode
08:40 < fenn> this pressure is because icebergs can be 400m deep (40 bar)
08:40 < fenn> do you really need a giant solid block of ice? probably not. ships are mostly hollow, not slabs of solid. i don't see why the iceberg idea has to keep all the internal solid mass
08:41 < fenn> for that matter, i don't see why it has to start with an iceberg
08:42 < fenn> refrigerant (CO2 or propane) solar panels, waste insulation. start a "seed" semisphere, then once you have that all frozen and insulated, rearrange the refrigerant lines to grow outward in a spiral like a snail shell, periodically walling off the ocean and pumping out the salt water (also like a snail shell)
08:45 < fenn> a big dumb slab of ice is nice because there's nothing to go wrong, but the tensile strength is not great, it's more expensive to insulate and tow, there's no method to grow it larger
08:45 < fenn> the snail shell method could also have redundant air bladders made of polyethylene or ice
08:47 < fenn> the living universe foundation (run by eric hunting?) has a lot of designs for ocean platforms, mostly made from concrete or steel. they tried "seacrete" electrodeposition of calcium carbonate, but it didn't work because it was too crumbly
08:48 < fenn> one of the designs uses large ~20m hexagonal barrels that absorb the wave energy by converting it into compressed air and running that through turbines, which reduces the mechanical stress on the overall structure
08:48 < fenn> near the center of a big conglomeration of hexagons the wave energy is damped out
08:49 < fenn> remember the iceberg broke off in the first place, that means it's about the limit of mechanical strength vs wave forces
08:50 < fenn> at the limit*
08:50 < L29Ah> not really the wave forces, it was sliding into the ocean and broke under its weight, no?
08:51 < L29Ah> since it was suspended at one side
08:52 < L29Ah> and huge icebergs don't experience much uneven load by waves like relatively tiny ships do, since there's no wave that can lift a part of the iceberg
08:52 < fenn> because it's below the wave depth?
08:53 < fenn> as for insulation, i guess you could just use giant bags of fluff like fiberglass insulation and inflate them with compressed air
08:55 < fenn> 400m depth is robot territory

09:20 < AugustaAva> ​twitter: <carl_feynman> @bayeslord This is work by Philip Morrison back in the 80s but I can’t find the reference.  As Uranium fissions in a reactor, it forms hundreds of possible decay products, many radioactive.  As these products decay, they interact with each other.  The stable end product is a mixture of (1/)

09:41 < hprmbridge> kanzure> "Lasers were invented in 1958.  They could have been built decades earlier.  The neon tube was demonstrated in 1898, but we had to wait until 1960 for mirrors and Brewster windows to be attached to the ends to make a laser."

09:58 < geneh2> you could have probably made a fluidic computer just about as fast as early relay computers possibly as early as the 1400s. The casting technology was there. Digital logic can compensate some what for manufacturing inaccuracy. But what we didn't have was the math nor the need to build them
09:59 < hprmbridge> kanzure> trebuchet calculations maybe?
10:00 < geneh2> cannons existed at the time, but calculus did not
10:37 < nsh> .wety ordinateur
10:37 < saxo> ordinateur - Borrowed from Latin ōrdinātōrem (one who orders), from ōrdinō (to order, organize). In its application to computing, it was coined by the professor of philology Jacques Perret in a letter dated 16 April 1955, in response to a request from IBM France, who believed the word calculateur was too restrictive in light of the possibiliti[...]
