I have been working on the idea of space manufacturing and various notions for Starship that might be compatible with it.

In current notions of Reusable Starship, there is an idea that a cargo of 150 tons could be lifted to LEO.

So, I am just guessing, if 50 of those tons could be for the raw materials needed in each flight, and you exchanged that for 50 tons of manufactured materials, that might leave you with 100 tons of coolants.  I am speculating that if you have 100 tons for cooling on entry, you have rather improved means to keep the ship in good shape.

Coolants could be Methane, Oxygen, Water, CO2, Nitrogen, or Argon, perhaps.

On the other hand, if you did a single use Starship to orbit, the claims are 250 tons maybe even 300 tons cargo to orbit and then the dry mass of the Starship as well if you could find a use for it.

Going with the value of 50 tons of feed materials up, along with the balance of the budget of 200 tons, you might lift a cargo capsule with the Expendable Starship.

Cargo Dragon weighs 11.5 metric tons.  Well suppose you lift 4 of them to orbit, to carry manufactured materials back, 46 tons for that.  But let's call that 50 tons.  So, you have 150 tons of lifted cargo left over.

Maybe you could make a single larger capsule of 50 tons to simplify things.  It might have parachutes and airbags.  Maybe even retro thrusters.

We all know that I am not a rocket scientist, but for entertainment, at this point we have a non-returnable Starship with a 50 ton Capsule in its cargo bay.  We are lifting 50 tons of raw materials up to our space stations, to feed the manufacturing.  This then leaves 150 tons to do other things I believe.

The Mega-Capsule does not have to be as sophisticated as Cargo Dragon is.  Starship will dock with the space station and drop off 50 tons, and 50 tons will be put into the Mega-Capsule.  Starship then goes suborbital, but ejects the Mega-Capsule, and then pushes itself back to orbit.

So, Cargo Dragon can be used 5 times.  I know that it is costly to reuse, but I am just Having a look at this.  It may be possible that the Mega-Capsule could bring back 50 tons of manufactured goods and maybe a full set of raptors and avionics.

Keep in mind that the 150 tons incursionary (But you need to drop the capsule to sub-orbit with some of that), but you may have gotten all that value. and you can recycle parts like raptors back down.

Granted the ride down in the capsule may not suit fragile cargo but may suit the bulk of it.  If you have fragile cargo that can go down, in a reusable Starship or a Dream Chaser, we might hope.

And I still have my eye on the non-reusable Starship, to convert it to other uses in orbit such as space stations and propellants for things like Magdrive.

If someone wants to correct my math, I am open to corrections in my thinking.

I thought your post was a good one.

I am thinking of the idea that the "Horrible Grunt" to Sub-Orbital, might be followed by a diagnosis period in Sub-Orbital, where an engine running on Ullage gas would keep a low orbit until, the diagnosis indicates a healthy ship.  So, if you have something like an engine skirt explosion, whatever that was, you do not produce long term space junk, in the orbits you want to use.

If you had a small engine, perhaps running on Ullage Gas, then you could proceed to orbit.

I consider it something to think about not a showstopper.  We know that the enemies of SpaceX progress will eventually seize on this to try to get into the way, so I am suggesting getting in front of it ahead of time.  Obviously over time the quality of the ships should increase, but the frequency of flights desired, may suggest that now and then there will be a clinker.

I have watched only the one video listed from this site: https://www.youtube.com/@MDVL_mindset

So, don't assume that other videos are equal to my ideas of whatever.

But this one I watched: https://www.youtube.com/watch?v=jeePF0w … valMindset

I recall I was told in public school that indeed Europeans were so unworthy and only the Arabs were brilliant.

I have been a creature that haunted libraries, and then of course later, haunted the internet.

Things I already knew that are in this video, are:
-The "Irish", or their similar, sailed in skin boats deep in to the north sea.
-The Vikings later did Viking stuff to those monks in Iceland.
-Columbus spent time in Iceland before his famous voyages.

There are various reasons why the Viking wave did not go too far into North America.  I recall a story that the natives "Skraeling's" had some sort of spear throwers, which gave them a technologically superior position.  However, when the
Europeans returned in about 500 years those people were not to be found, nor their weapons.  The Vikings were never that many people in Iceland and Greenland, and even Greenland had an acceptable climate at about 1000 AD.  Then of course the Mini Ice age helped wipe out the Greenlanders and almost finished the Icelanders.

I was also aware that Vikings were guards in Byzantium, and that Vikings went down to Bagdad to get silver.

An item of importance in the video that I did not know was that at some point, the plough was improved along with horse harnesses, allowing agriculture to expand in the North.

My own theory is that that Alpha Bed Hoppers are the downfall of civilizations.  That is, when the Chads and the Tyrones are allowed to play Coocoo bird with other men's women, then the skills disappear and so then also the wealth.

In the north, that could not happen as you had to have better skills to be powerful than to impregnate a peasants woman.  But if farming was enhanced, then there could be peasants for the Chads and Tyrones to impregnate.  So, a bloom of wealth, may be destined to be ended in poverty.

The resurgence of fossil fuels in the USA at least has balanced out the mischief money that was accumulated in the M.E.

The effort to de-industrialize the west, which was very likely promoted in the shadows by the Chads and Tyrones of Fascism, Communism, Socialism, and the M.E. oil money , is being resisted thankfully.

I was interrupted by a visitor during this post and have sort of lost the thread of thought, so I will end it here.

I am thinking about accessories for the Starship such as a carry-in-cargo 3rd Stage.

Technically Star links will already be that as they have their own propulsion systems. 

Diameter of Starship 9 meters / 30 feet.  A new version may be significantly larger.

I will grant that it is a small ship.

A credible member here has opinioned that it could not do a return from the Moon with its existing heat shield.  I have no reason to suppose that that opinion is wrong.

But I think I may see a way to do something that is a bit new.

In the case where the NOVA went to the Moon and the shield traveled with it, it might be left in Lunar orbit while the NOVA would land on the Moon.  Then be reattached for the trip back to Earth.

I have not provided propulsive means to transfer the NOVA to and from the Moon.  That would be extra.

An atmospheric entry mode is suggested in the drawing.  Returning from the Moon, the Shield is added to the ship as shown.

The "Footprint" is larger than that of the NOVA, which may help.  The NOVA will ride in the wake of the forward heat shield.

The thrusters for the NOVA might be assistive in cooling.  One possibility I have in mind would be a high Oxygen Mix, which of course would be like a cutting torch, possibly.  But if the shield is of a material that resists Oxidation on it's inner surface, it might work.  The pressure and heat of the exhaust might be milder than that of a cutting torch.  The heat quenched by a lot of Oxygen perhaps.  Of course I am thinking of Lunar Oxygen as a coolant.

But dilutant gasses such as Argon, Nitrogen, CO2 could be added to the mix.  So, you would do a little combustion and then add a lot more Oxygen, Argon, Nitrogen, or CO2.

The shield will have to detach in the atmosphere after the heating is over.  It may have been manufactured on the Moon or lifted to orbit in a Starship.

It might be one time use, or just perhaps might be outfitted with a parachute to land like a Falcon 9 Fairing.

For instance, if Starship will expand its diameter, and yet also keep the current diameter starships, then the larger Diameter Starship may be able to bring back an entire engine section of the smaller diameter Starship.

This would be a little like the logic for ULA's Vulcan where the tanks of the 1st stage would be disposed of after use, and then engine section and avionics would be brought back for reuse by some heat shield and landing method.

But in this case the Ships would be rendered into propellants, except for special parts like the Engine bay with engines.

Of course, that requires modified Starships.

I don't want to contaminate your purity of essence, but if wind is you motor on occasion, could it be possible to have a parallel source of motor from an electric grid?  Off peak power perhaps?

So with the wind you have to work when the wind blows, but with off peak power, you have your choices do, or don't' do.

I am not talking about your Hobbie project which is wonderful, rather, supposing Humanoid Robots become actually useful, then one could do some work around the homestead, but at times work with the wind or with off peak power, if that is available at a reasonable price.  This of course would be a different installation.

A robot could work at night, where most humans would not.  Wind may blow at night.

I request tolerance that I can say a few things.

-I think that if Starship is going to shed materials, perhaps they should do the shedding in a suborbital mode and then go to orbit.  Hopefully leaving the shed materials behind.

-I think it might be wise to try to land a Starship on the old peg legs.  That way if they are successful, they might fully examine the ship.  This then allows them to make improvements before they risk a tower catch mishap.  It might be that if they can make a good enough landing pad on Mars some Cargo Ships could land on the peg legs, maybe improved peg legs.

At this stage in Starship development, they are probably making each Starship obsolete after one flight anyway.

And yes I would like to see them catch a newer Superheavy if it seems likely to be successful.

It is needed for the reader to understand that I had a Scottish Canadian Grandparent, and a Yankee American Grandmother who was largely English with a bit of Scottish and French Huguenot.   I also had two Swedish Grandparents.

It is not my practice to hate the British, as they are in my ancestry and have not personally harmed me as I recall.

But I like this video, and hope that the British can also get a better situation for themselves.

I think we have had 4 American revolutions though.  WWII was the third, I feel, but we got entangled in the worlds degeneracy in that as well.

I see the democratic party as simply the Confederacy again, and their very valued urban hell holes are the plantations reimagined again.  Remember that not all slave owners were WASPS, in fact most WASPS were not slave owners.

A very great number of slave owners were in Africa itself and were themselves Africans of some sort.  They captured and sold both Africans and Europeans into slavery.

I have hopes that the heat pump in this post from elsewhere can create pyrolysis temperatures, and that I have not misunderstood what is actual about it: https://newmars.com/forums/search.php?s … 1667206299

Pause..............

If we can have a heat pump that cools a tank of slushy water and also a brick pyrolysis oven, then the cold side can both condense water out of the air, and the hot side can do pyrolysis on organic matter.

Data Centers might use the slushy water for cooling.

Then you use solar power with battery capacity that you desire.  You might also tap into a grid which may include wind power.  So, you would run the heat pump continuously or intermittently on the basis of energy availability.

The heat pump claims to go to 400 degrees C: https://www.youtube.com/watch?v=uawATQk … ModoEnergy

I am watching it again to try to understand if I have misunderstood what they claim.

Pause..................

So, anyway, if you have a slushy pond covered with solar panels, then you might cool a data center with slushy cold water.  If you have humid air outside, you may use fans to blow that air though this to hope to condense water from the air and accumulate water.

The hot side, I hope can heat a brick oven hot enough for Torrefaction.  I feel scared that they do not actually have the ability to reach the necessary temperature.
