Sometimes, you can turn box about to access via open side no-one else noticed...

My thanks to 'HC' who sent me a summary of Magnesium fire-fighting. This is a non-trivial task. Once Mg gets going, it will take nitrogen from air, oxygen from CO2 or water, halogens from eg Halon. To break its *truly infernal* fire triangle, bury in sand, quench with a water flood or add...

"...by wrapping the hoist chain around the column" IIRC, the process is 'To Parbuckle', and done by lumber-haulers. Take care !!

Again, thank you !! Being able to cry, 'Oh ? Ooh, Shiny !!', rip up and re-write a sub-plot is one advantage of keeping a hefty weekly-ish chapter editing buffer { 6~~8 } for 'City of Fresno', sequel to short 'Chaparral', #17 in...

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...
