So, this is an object that already resembles a "Solar Moth": https://isaacarthur.net/video/solar-mot … lar-sails/

In 2038 the video says the object could be deflected into the inner solar system by Jupiter.

It would probably be a good thing if it could be tamed, into a "Solar Moth", and have it propelled itself to a useful and not destructive purpose.

I don't know if the gas pockets could be tapped and directed to a thrust method.

The materials of it would be very useful in the inner solar system.  But Asteroids like Ceres and 10 Hygea might have equivalent resources.

I would estimate that Solar Panels will max out at about 37% and be part Silicon and part Perovskite.  The prices will likely be significantly less than it now is.

For Scotland, I would think that the sensible thing would be to have Ammonia Tankers, that would dock, and on the shore would be a power plant.  The Ammonia would be bought from competing producers around the planet.

Ignoring that there is wind power for Scotland, as you guys just don't accept that it is a good thing, then it would make a great deal of sense in Scotland, to convert the Ammonia to electric power on the shorelines and convey it by electric grid.
The distances are not that large.

I think that a thing that is emerging in my mind is local multiplication of value.  The political trends of the 20th century permitted a vengeance against the "Rust Belt", by those who resented, and also a desire to capture it's industrial capacity to relocations to the Sun Belt, and overseas.  America's Oil had run out.  And it certainly looked like the rust belt was less desirable, and labor with less unionization was available in the Sun Belt/Bible Belt. 

I do not hold much of a grudge about all of that, it was more or less a fluctuation in the pattern of reality.

A question can be asked about solar power and "Aspin World" in North America.  And a comparison could be made to the South West of North America.

The question is, "If Arizona thought Solar power was a good thing, at 19% efficiency a few years back, what about solar power below the Great Lakes, when efficiency becomes 37%.  Even in many of those locations, the payback can be real.
But the surrounding assets are often better than for much of Arizona.

South of the Great Lakes was the Heart of the Rust Belt.

Global Solar power shows that the Rust Belt is pretty much similar in latitude to the Iberian Peninsula: https://globalsolaratlas.info/map?c=24. … 9.113286,3

But of course, it has more cloud cover than Spain/Portugal.

There are monthly maps in that web site that are quite interesting.  April through September look rather good for the Rust Belt.

Robot labor to some significant amount could migrate with the seasons.

In the case of the reclaimed Dairy Farm that I suggested be groomed, in the early season trees could be worked with, and then clean up of left over growth from the fall.  Then though summer and into fall "Weed" farming, (Not the wacky kind), could be implemented.

Penty of energy to do pyrolysis with.

So, I am anticipating making this old farmland groomed and a proper place for family people to have children away from the reach of Urban Loony Tunes, who want to exterminate the human race.

A portion of the population might be migratory as well.  Sun following.  A greater portion than now.

With Starlink and Humanoid Robots, teaching can follow the children, if they migrate.  Due to AI and robots we are supposed to have an age of abundance.  This would perhaps allow many people to have both summer and winter homes, if those were relatively modest in most cases.

A bulk of people leaving the rust belt in winter, would relieve the stress on water resources for the winter.  And moving to more southern states, their water resources could supply a expended population.  So, in the summer, the water resources of the southern states would get relief.

Also in the wintertime, in the Southwest, the still abundant solar would allow the creation of water resources from the seas or the air even.

So, for solar, I think it is less necessary to only use it in the Southwest.  And the Southwest has a strain on it's water resources already.

The comparison would be Saudi Arabia, and Europe.  Yes, Saudi has much better solar, but Europe has natural water in abundance, on average.  Saudi have to make their water, using up their solar energy.  Europe can use its solar energy for other things.

This is a continuation of the previous post #241.  The previous post included information on how to create low efficiency
solar panels.

But an evaluation in the following video, shows that heat engines are not a better deal at all.  An evaluation of what energy you get out for the energy you put in.  (This applies to solar heat engines, not nuclear heat engines).  But we do not know where we could get materials on the Moon to make nuclear heat engines, at least not the nuclear fuel.

Per the Moon, https://www.youtube.com/@Anthrofuturism , has a lot of articles that may interest you Calliban.

I think that they use Calcium Oxide as the bath, but maybe not.

The British created Metalysis which uses CO2, the Europeans then modified it to not need Carbon, and I am not sure if Blue Origin uses a derivative of it or not.  They don't say.

Perhaps more later.

I would like to post on this.  You guys have some good and critical information, but I am somewhat optimistic.  Solar Panels will likely become about 50% more efficient within 10 years, I suspect.

There seem to be 3 main concerns about the solar panel industry.  (1) China dominates it. (2) They burn Coal. (3) They reportedly use abused labor.

Expanded robotic labor could address #1, and #3.  As for burning coal, I am not sure we should care that much, if it give us a 1/25 or better return of power.  (This presumes that it takes 1 year, (In the future), to payoff the energy to create the solar panel and that the solar panel lasts 25 years).

So, we can have a Carbon loop.  If RethinkX/Tony Seba are correct that Precision Fermentation will replace dairy cows, then that land will perhaps go feral.  I have contemplated having it be groomed instead of going feral: https://newmars.com/forums/viewtopic.ph … 50#p233650

In using "Superpower" to process organic matter to create Biochar, vast stretches of land can be rendered semi-wild but productive to produce both electric power and to bury Carbon into the soils of those lands.

Also, if it does turn out that vast amounts of Natural Hydrogen are to be found, enough for a century at least, then we have breathing space.

Biochar might eventually replace coal, but for now it is likely easier to simply use coal and draw CO2 out of the atmosphere using photosynthesis.

Also Elon Musk does not feel that global warming is likely to kill the planet or the human race.  I agree.

Also, I regard elevated CO2 as a nutrient now more than before and a net benefit so far.  There is some reason to believe that the CO2 level is saturated and has been for some time.  I think kdb512 has previously agreed on that.

If Tony Seba is correct and much of the Dairy Cows go away then the Eco-Karens (Cows), can stop worrying about cow flatulence.

I think we may be in a good spot.

That is useful information Calliban.  It is a hard nut to crack, I have been thinking about it off and on for a long time.

A best guess on possibility is a tank of liquid air with perhaps 18% Oxygen, and then if you could cause that to burn with a fuel, such as Methane.  But there would be thermal problems possible and poisoning from CO and CO2 would be major concerns.

A 4% CO2 is considered to be immediately lethal.  But maybe a lesser exposure could be a preference to dying in a fire.  If humans are not involved, then it would not be a big concern.

I am thinking of Stairwells in tall buildings and perhaps for homes some chance of suppressing a fire.  But as you have mentioned the nature of the structure will make results variable or not possible.

For the stairwell, I am thinking of something like a jet engine running on the depleted air, using Methane fuel.  But if you could use Hydrogen, that would be much better as to eliminate the Carbon compounds.

For Mars, I am imagining plastic envelops to contain somewhat depleted air inside of ice tunnels and vaults.  It should be possible to make plastics largely from water from ice and from CO2 in the atmosphere.

I am thinking of maybe 16% Oxygen, and then humans will need to have a additional source of Oxygen perhaps from an Oxygen Concentrator.  I hope that vast volumes of such tunnels and vaults could be created, but I do not want a runaway fire possibility.

As I understand it 16% is temporarily survivable.  But humans more often would be in other chambers with greater amounts of Oxygen.  Robots should do just fine in 16% Oxygen.

You know that I have the greatest of respect for you Dr. Johnson.  And I agree that if it is on Utube, on average, it is at least half under suspicion.  I believe you that it might make sense to get these resources from the canal/vendors.

But the BE4 is Methane fuel.  BE7, I think is Hydrogen.

I don't expect anyone to be perfect, especially not me.

I think we all appreciate your contributions here, sir.

Further thoughts on the prior post, "Wick Cooling".

A combination of external and internal "Wick Cooling" might be useful.

It is possibly in the nature of wick cooling that hot spots will draw more coolant fluid to themselves, so that if some failure occurs in the external heat shield, the internal wick shield might cover the problem well enough to allow the ship to survive.

We also could consider a "Squirt" gun in open spaces such as the Oxygen or Methane tanks, a robot that might squirt a coolant at a Infared visible hot spot.  Mayb CO2 would work, maybe Nitrogen.  Of course, you would not want to damage things with thermal shock either.

An EV owner might also get financial incentive to slave the battery pack in their car to allow it use in stabilizing the grid.

Just a notion.  It might use too much coolant though:

Maybe could be used for some things.
