The second best part pulls double duty

@elonmusk In short,sez Grok, you need on the order of a few square kilometres ( 1.5 - 13.0 ) of high-emissivity radiator surface, kept relatively hot and always looking at cold space.

@elonmusk Ring of power the cold memory.

What space is good for.

Holographic-like low frequency recall of vast information stores

Real time orbital modelling

Not MW of forge.

[J Geary @jjpinni]

@MaaSonder I so want Grok to have a 3d understanding as it feels like abuse to make it draw pictures that are physically and engineering true so far.

Of me and it.

@TheUgliest_Man When I advocated for the next United States expansion to include Australia's 7 states I was laughed at.

[J Geary @jjpinni]

@elonmusk @spencerpratt I agree, the overlapping shingle tiles fail in reentry but I never claimed that to be the answer only an intellectual step towards the answer.

[J Geary @jjpinni]

Cold memory lives in space Elon. Hot forge needs heat rejection ie Earth ocean.

A cislunar ladder with rungs hundreds of m/s apart enables only people and low mass cargoes to ascend to LEO and thence to llo etc. solar powered em launch from station rungs with lunar polar ice moving down the ladder closes the loop.

Needle-200 spacecraft

See my other posts for a sampler of solutions.

A ring of power self lifting drop tanks
25% extra payload for liquid fuelled rockets
The same stage 0 extra propellant and main rocket engines math as the launch tower concept
A 20s burn lifting tanks of lox and ch4 or rp1 is enough for a new side booster but the throttling...

@elonmusk @SpaceX What do think of the rings I posted, Elon?

[J Geary @jjpinni]

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.

[J Geary @jjpinni]

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

[J Geary @jjpinni]

A cheap ring

Tanker fuel transfer, latch both ships together, spin on long axis between them

[J Geary @jjpinni]

@GoToImpulse Voidsmith calling.

Post chemical engine rings of power.

A timberwind evolution, the blunderbuss.

The simplest one.

Check my X posts.

[J Geary @jjpinni]

@SpaceX @Starlink The ninth ring of power is orbital compute.

Not going to gift this.

Talk to me, Elon.

[J Geary @jjpinni]

Ring of power

Spinmeltfreezecoat orbital foundry.

8m diameter solar concentrator is about 50m^2 surface

About 70kW of high temperature sunlight. T^4 rejection....

[J Geary @jjpinni]

@SpaceX @Starlink Eighth ring
Spinmeltfreezecoat orbital foundry

For 8+m solar concentrator, optical surface
Fabric PV is not the only use of unfiltered sunlight in orbit.

I so love the 8m x 18m x 100t cargo solution space. I can do this all day, Steve.

[J Geary @jjpinni]

@SpaceX @Starlink Seventh ring ( a cheapie )

Tanker to ship fuel transfer

[J Geary @jjpinni]

@SpaceX @Starlink Sixth ring
Orbital debris cleanup using repurposed old starlink and other junk.

See my posts for a taste of insight.

[J Geary @jjpinni]

@SpaceX @Starlink Fifth ring for mortal men

The cislunar ladder of propellant free stations.

Bottom rung is Leo. Usual crap images.

[J Geary @jjpinni]

@SpaceX @Starlink Fourth ring persistent, starship 100t launch payload class , orbital spacecraft
