Again, thank you. So, rather than coat the magnesium with silica glass, Plan_B is a TBA polymer...

Thank you. Still world-building with passive atmosphere or vacuum processing... If conditions less extreme than an electric arc-furnace, could micronised silica be dispersed into molten magnesium without reaction ? Tangential, just as some ChemEng systems have 'Silica on S/Steel' plumbing &...

World-building: Assume *passive* atmosphere or processing in vacuum... Does molten magnesium react with pure silica, SiO2, as powder or glass-fibre ?? Would it even 'wet' the glass ?? -- I'm world-building environment where iron is as exotic as our titanium was, perhaps only 'meteoric', but...

World-building... When a pressure hatch with a central 'wheel' drives its 4/6/8 radial bolts to 'dog' to coaming hard-points, what are those hard-points called ?? Ashore, a dead-bolt mates with a striker plate or, if surface-mount rim-lock, a robust 'keeper'...

If 'rod' is conductive, monthly passage through Earth's geo-tail may influence perturbation...

Thank you. So, though the competing processes persist, their balance is currently un-clear.

# World-building, NOT a school / college question. # What is known of Thermohaline circulation during 'Snowball Earth' episodes ? By analogy with processes beneath Antarctic ice-shelves, I would expect *some* freeze-out to continue, *some* cold saline 'bottom water' to be generated...

IIRC, a long keel is inherently robust, and provides excellent lateral stability, making it easier to hold a course, so preferred for 'passage' and cruising. Twin keels / skegs let you 'take the ground' without steep heeling or stilts. And a smaller routine or 'emergency' rudder may suffice. A...

Though your gear system differs, IMHO, result resembles a 'Variable Slip Differential', where clutch limits 'independence' of output shafts. FWIW, perhaps research epicyclic gear-boxes with ratios changed by variously braking stages ?? A colleague explained such to me: Seems such constant-mesh...

Perhaps check out 'Wet Bulb' vs 'Dry Bulb' temperatures in addition to 'Wind Chill' ? FWIW, during thankfully rare UK heat-waves that coincided with Saharan dust incursions and dire pollen-count 'Spikes', only desk and wall-hung fans, plus big 'Air Mover' stirring stair-well, kept my wife and I...

IMHO, there is a further issue: Is this a 'brushed' DC motor ?? Such are notoriously 'Noisy' tech. Been a while since I did hobby robotics, but brushed motors were the domestic equivalent of 'Spark Gap' transmitters. They needed close-coupled, over-rated, back-to-back Zeners, warily-rated...

FWIW, there is a wandering inter-stellar population of genuine 'Rogue Planets'. IIRC, some were probably tossed 'wild & wide' when their host star 'evolved' off main-sequence. Some probably came via the 'Brown Dwarf' route, perhaps not accreting to full size. Almost certainly, some were ejected...

Wiki, YMMV, has... https://en.wikipedia.org/wiki/List_of_nearest_stars This includes prior and pending passes... https://en.wikipedia.org/wiki/Scholz%27s_Star This mini-binary came close enough ~70ky ago to disturb Sol's Oort cloud. But, IIRC, such objects need another million years or so to...

Um, this *is* the tamper-trapped 'Covenant' Ark, with historical provenance, rather than the 'Noachian' absurdity ? The latter mega-hyped from Gilgamesh river-flood reportage ?? Two thoughts: If you dig into the electro-chemistry, you'll find it is as easy to use a primitive battery to...

If the 'Baghdad Battery' was used for electrolytic acceleration of acid-leaching, comparable to the Incas' acidic Andes streams, rather than a gold-plating system, then a 'Voltaic Pile' might follow. Given the 'Angelic Ark' was claimed to be a hefty whatsit, it could readily accommodate enough...
