The second best part pulls double duty

Vacuum welding lips one inner, one outer, simple ( in theory simplest two metal parts become one join ) In theory there is no difference between theory and practice

So solar concentrators can bring the sun's surface heat to an orbit near you ( as a maximum ) > 5000 K Leaves the 1300W/m^2 flux looking a bit anaemic

A simpler version of the grooved rings fix for the balls in frits radial heating axial outlet design.

Ring The Fukushima division What a fukking mess. So close to the front door of the reactor building. Yet somehow totally beyond TEPCO. So obviously needing puppeteers, physically controlling hard rad remote robots ( or mechanical computing brains ) , mechanical TV, overhead cableways, mechanical power , and a large number of beer kegs. ( Seriously, place a suitable amount of corium or other radioactive crap inside a water filled stainless steel keg and get that filth out of the meltdown zone of units 1-3 and back to processing ) C'mon Elon, SpaceX. Buy back some respect and a solid gift to us all. Get paid !

Ring of power the compute can. As an example of solution space thinking, rocket regenerative cooling is a good way to extract heat from the inner surface of a compute can. Channels move the eg ammonia from the hot(ish) inner surface to radiator condenser wings.

Now synergy between these rings of power is implied. Orbital spinmeltfreezecoat foundry making solar concentrators to outfit Needle-200 variants with compute in a can with cislunar ladders with reusable starship as first rung with lunar ice flowing down to Leo with reusable falcon human buses with ...

Of course, SpaceX will entertain me with their brilliance and solutions!

Ring of power alternative orbital compute. Now for some errors and misleading images. Instead of racks with wings a starship cargo can with backbone grooved into the inner surface. Doing my usual progenitor fruitful rootconcept shape-in-solution-space thing. Ie this is just a pointer to a larger solution space family : nested inner shells , cold holographic memory, native topology, replace racks but keep backbone, see needle-200, forge/loom/needle compute tasks, etc. Getting towards the end of my free civilization gifts

High g for humans. Only a small addition to Grey/Webb iron maiden. (31g for 5s) !!!!!!!!! A loose bag of air at chest level that gets compressed by the water to equalise airway pressure intrinsically with the g pulse.

Spinning is key for transfer of fuel. The other axis spun, and zero g pumping, and pressure tanking, and most other solutions just didn't coalesce into a convex objective function in solution space

Still it only needs an engine to lift 10t cargo tank for 20s. Reliable deep throttling and matching a liquid fuelled rocket acceleration for such a short time is a fairly simple engine
