Re: Void Postings
For Void re heating ship bottoms to reduce viscosity
https://newmars.com/forums/viewtopic.ph … 89#p239789
This is an interesting idea. I hope you will do more with it.
Your AI friend might be able to run some numbers to see if it would make a useful difference.
Ships by the many thousands are likely to be in normal service around the world. They all must generate heat to produce power, and lf the energy consumed is likely to reach 30% or so efficiency of motion, then that 70% difference likely goes into the atmosphere right now.
The plumbing required to route hot water around the hull will add greatly to the cost of the ship.
A builder would need to balance costs of installation and maintenance of a system to deliver waste heat to the ocean instead of to the atmosphere against any benefits.

Re: Void Postings
For Void re interesting links ...
You and Calliban are doing the heavy lifting right now, while we wait for SpaceNut to figure out how to attract and retain more participants in the forum.
Thanks for the amusing comment on the idea of just a few people on the Moon so don't grow anything.
Whoever wrote that is stuck in a 15th Century mindset. Thankfully we have people like you and Calliban to take a more optimistic view. Science fiction writers have filled the Moon, Mars and many other places with plenty of people (and aliens), so we do have the expansionist view as an alternative.
The next few years should be interesting, if we (humans) can figure out how to put evil into a jug and keep it there.

Re: Void Postings
For Void re post in Starfall topic ...
In a recent topic, in June of 2026, you introduced an idea I have not see before: using Lunar material for heat shields.
This may well have been considered and perhaps even studied.
I had a vision of meteors streaking across the sky, and many of them reach the ground. The atoms which are ablated become part of the mix of material in the atmosphere, and perhaps water will eventually collect around some of those particles, leading to welcome rain in some areas, and less welcome in others.
If we are lucky, perhaps a member who knows about such matters will consider it, and more importantly, share with the forum what might be possible and even what might be practical.

Re: Void Postings
For Void ....
GW Johnson took a look at your heatshields from Lunar regolith idea...
The result was not encouraging ... Please ask your AI friend to help you show why that is a good idea.
You have unlimited solar power available to make anything you want to make out of Lunar Regolith. The issue is time. GW Johnson appears to believe that carbon is required to make a decent heat shield. I submit for your consideration that perhaps humans are using carbon because we have so much of it, and it never occurred to anyone to try anything else.
Please do NOT take this feedback as directed at you personally, as you so often do.
This feedback is NOT about you personally! It is about an idea you launched into the cosmos! Please let go of the idea and let it sink or swim on it's own!
If the idea is good your AI friend will be able to show it's value. It the idea is terrible, your AI friend should be able to render that judgement.
Either way, the NewMars audience is what matters! We have the opportunity to bring value to our readers, and that includes exposure to good ideas or to bad ones that should be avoided.

Re: Void Postings
For Void... just FYI ....
I've been attempting to bring new members into the forum. Today I extended the invitation once again, and the recipient is likely to be reviewing the web site to see if is is suitable for elementary and junior high aged students. We've been operating with a very relaxed atmosphere here, so occasionally old time members may say things that they do not realize would be concerning to parents. I'm sure you won't have a problem, but I thought it might be a good idea to let you know the forum will be under review.
The intention here is to attempt to build up an audience for GW Johnson's class material on elementary ellipses, which is precursor to study of spacecraft navigation.

Re new topic AquaWorlds ...
Would you be willing to edit the title to include the word "water"
There are studies that might be added to the topic if you were willing to include the word "water"
Here is a list of existing topics in Terraformation that contain the word "water"
Your topic appears to be different from the others ...

OK, if this "Index» Terraformation» AquaWorlds (Water Holding and Water Transporting Methods)" ,
Is not good enough, then please craft a name and I will use it.

Re: Void Postings
For Void!
Thank you for considering my suggestion ... My hope was that persons looking for waterworlds would find your new topic.
Your explanation of what you have in mind is helpful.
You are (apparently) not thinking about worlds that are mostly or entirely ocean.
The clarification you've proposed should help readers to understand the direction you'd like to go with the new topic.
The reason I picked up on your topic is that I just read a report about scientific research studying weather patterns on worlds with varying amounts of water, from the example of Earth through planets that have only a few mountain peaks standing above the water.

Re: Void Postings
For Void! Thank you for bringing Stanford Torus back into view for a day!
https://newmars.com/forums/viewtopic.ph … 65#p240165
That was a significant moment, when leading talent of the time assembled to consider the potential of rotating habitats.
For anyone who might be interested Wikipedia has an article on the subject, and at least one book was published about the design.
https://en.wikipedia.org/wiki/Stanford_torus
Part of the lore associated with that NASA summer study was the argument about rotation rate. The advocate for 1 RPM won that debate, and everything flowed from that single data point.

Re: Void Postings
For Void re post about robots ...
https://newmars.com/forums/viewtopic.ph … 81#p240181
Thank you for this glimpse of the evolution of farming.
Those machines are the result of many minds harnessed in support of visions of what is possible, and beyond what is possible, what is economically self sustaining. Ultimately, the payback for all that thought and hard work is the fruit provided by solar energy.
Humans and their progenitors have been harnessing solar energy for hundreds of thousands of years. It is rewarding to see how the tools have evolved.
Since this is the NewMars forum, I will venture a guess that we will see automation of the growing process on Mars, with the distinction that every growing facility will be enclosed. Automation for those enclosed spaces will be adapted but (I suspect) no less sophisticated.
We (Admins) are venturing into the realm of education in robotics, because there are millions of young minds alive today on this planet, and some of them will find study of robotics rewarding.
The applications of robotic systems (automation such as you have shown us) on Mars is beyond anything achieved on Earth due to the unforgiving nature of the environment. We will need all the human minds able to think at the required level that Earth can produce.

Re: Void Postings
For Void re post about possible use of CO as a propellant with LOX...
The post in which this item appears was interesting. Thank you for doing the research to bring those ideas into view.
It is possible that you might have missed a detail due to the large quantity of information you collected.
Please investigate to see if the source for this quote was taken out of context?
Storage: CO liquefies at about -191.5°C, colder than LOX (-183°C), so LOX tanks would need to be insulated to prevent CO from freezing Space Exploration Stack Exchange.
That quote was pulled (apparently) from a web site where people without qualifications are free to make statements that make no sense. If you were willing to take the time to investigate, I would be interested in the facts of this situation. The statement quoted seems to imply that the colder substance might freeze if brought into contact with a warmer substance, so the reader is left unsure of what is proposed.

Re: Void Postings
CO & LOX have a Specific Impulse (Isp) of 250 to 290 seconds in vacuum. That's poor. NASA looked at this as a means of Insitu Propellant Production before Robert Zubrin. His improvement was to bring hydrogen from Earth, used the sabatier process to convert to liquid methane. Which has Isp of 350 to 380 seconds. And LCH4 boiling temperature is -127.3°C at 10 bar pressure. So moderate pressure in the tank. Not even as cold as LOX. That makes it easy to work with.

Re: Void Postings
For Void ... in a recent post, in mid July 2026, you offered an intriguing idea that Uranium might be found in the oceans of objects other than the Earth.
This is an idea that needs to be pursued to see if can be supported by evidence, or if it must be labeled as pure speculation.
Please see if one of the AI systems can find evidence to support your interesting idea.

Re: Void Postings
Mars Odyssey used a gamma ray sensor to detect thorium. It produced a map of thorium concentration across the surface of Mars. Again, this is based on gamma ray emissions, with assumption that gamma is produced by thorium. On Earth, thorium is used as an indicator element to find uranium. That means, when there's thorium, there's a good likelihood there's also uranium. I have argued thorium itself can be used as fuel in a nuclear reactor.
