Re: My Hacienda On Mars

For SpaceNut re #174 and #175

Thanks for collecting all that earlier work!

I read through it carefully, and must have missed something ... I can see the expected processes for making kerosene from petroleum mined from under the Earth.  What I am missing is the procedure for starting with Carbon Dioxide and water, and ending up with kerosene.

I did see CO2 mentioned as part of the process, but not as the source.

The hillside habitat starts with combination of post 43 and 44 to make use of basalt and other ealy leveraging post.

Its that use of leveraging of basalt threads or kevlar which has lead to making rockets or at least there tanks for hold what we process from mars insitu for other purposes. Which means sub orbital for mars and to orbit delivery for mars goods from one place to the other. This has been evolved from teh balloon topic.

New registry business that make use of existing to make mars more capable and less dependant on earths delivery resupply system.

This topic Compressed gas balloon rocket for Mars launch is the means to these next plots development depend on earlier plot being developed for the future mars. To which the ability to rapid cool gaseous sources have been laid out with the sabre engines system.

A while back, I used JPL data on ultimate expected yields for methane-oxygen synthesis from CO2 and H2O to calculate the efficiency of the process.  It came out to be 5-8% - electrical energy to chemical product.  If one assumes that the power used in this process is provided by PV arrays with 20% efficiency; then the overall efficiency (sunlight to chemical fuel) is 1.0 - 1.6%.  It really would be almost as efficient to grow biomass in greenhouses and convert it into a liquid fuel.  Or maybe a solid fuel that could be used in a hybrid rocket.

Maybe Void's ice ponds will eventually be used to grow aquatic biomass.  This could then be dehydrated by leaving outside in the low pressure Martian atmosphere.  The dry biomass could then be compressed into fuel slugs using some sort of organic binder and loaded into a hybrid rocket.  There are quite a lot of byproducts from agricultural systems that could be converted into rocket fuels on Mars.  We could in fact grow algae for that exact purpose.  Dehydrating the algae would be easy on Mars, as all water would rapidly sublime in the low pressure atmosphere.

Re: My Hacienda On Mars

This is for Calliban re Plot 0037

Thank you for establishing a stake in Plot 0037 ... I apologize for the delay in performing the "paperwork" to register your claim.

The My Hacienda topic has been languishing since it was created following Louis' inspiring vision of Sagan City (2018).  Louis has gone on to other visions, but SpaceNut and I have been attempting to keep My Hacienda alive until someone came along to help fill it out with 2750 visionaries who are willing (and able) to perform the mental gymnastics required.

Your post #180 (in reply to SpaceNut) inspired me to see if you had posted anything else in My Hacienda, and to my delight, there it was!!!

If anyone (today or in future) reads this and decides to participate in this attempt to create a "virtual community", ** please ** make sure that either SpaceNut or I follow through with the (very simple) registration process.

Calliban, if you call up the PlotMaster, you will find your claim duly registered, with a pointer to the specific record where you established your vision for a product or service (or combination) in Plot 0037.

Here is the next piece of the vision for this topic, which I have been waiting for a ** real ** subscriber to explain ... The idea is to build up that specific record with all the details that would enable you (or someone else) to pick up whatever supplies and skills are needed, and set up shop on Mars.

In other words, when you want to add a feature or capability to your plot vision, search for Plot 0037 (and yourself as author) and then edit that record.

The reason for this request is two fold ... First, my hope is that we can keep new posts in this topic to as low a level as possible.  Second, your vision can be built out in that database record with as much detail as needed, and you won't have to go looking at other database records to gather whatever you've recorded.

***
Now, for SpaceNut in particular, but for everyone who might have an interest in this project ...

The vision of My Hacienda is easily muddled, as can be seen by reviewing the topic ...

I will try to describe what I have in mind here, to help everyone who decides to help out.

SearchTerm:VisionForMyHacienda

My Hacienda is intended to reflect a 2020 level of civilization, transplanted intact into a new environment. 

It is limited (arbitrarily) to 2750 plots.  The idea is to see if we can figure out how to set up a sustainable community of 2570 physical locations, with as many people as can comfortably populate each location, with the expectation that ** every ** product and service we (in developed countries on Earth) take for granted will be present.  Furthermore, in accordance with (what I understand to be) a fundamental tenant of capitalism, there need to be at least three vendors for each product or service defined.  Thus, in addition to Plot 0037, which is now associated with Calliban, there will be at least two other complementary and competing providers of libation for the community.

Thank you again for your participation in this venture!

Your feedback on any aspect of the vision is most welcome.

Re: My Hacienda On Mars

Plot 0046 Methane manufacture, for rocket fuel directly registry: on the first page we talk about this as its a key to man being able to come home at any of the mars windows for return.
Many of the posts with in this topic talk of the elements for making methane and of the energy required to make that fuel.
This is why topic discussions and the plot id in those topics are critical for the my Hacienda to not contain it here.

I have tagged the topic: In-Situ Propellant Production, design a opensource demonstrator with the Plot identifier.
It coincides with getting a toehold for sure and is the early attempts in proof of concepts for making fuel.

Fuel at a full scale manufacturing would come later...with the 46 plot identifier for sure so we are going to need another bump in the list numbers which are now not really in a priority or ordered listing but more like an index...

The void ice covered ponds are another topic which should be plot identified for its construction and future uses for life support and for energy storage in organic form.

The quote below could go into My Hacienda, but I'm holding off for the moment due to updating of the PlotMaster with Calliban's claim for Plot 0037.

The issue at hand here is the growth of air conditioning on Earth ... it will not be a matter of growth on Mars ... Air conditioning will be a constant and perpetual requirement for life on Mars.    I liked Calliban's recent description of a human habitat at the bottom of a lake on Mars, where the pressure of the water outside the habitat would equal the pressure of the air inside, thus reducing the need for bulk in the walls.  I like the idea of Mars residents becoming aquanauts as an alternative to the default astronaut life.  Calliban's scenario deserves serious treatment by one of the many capable science fiction writers alive on Earth at the moment.

https://getpocket.com/explore/item/the- … ket-newtab

Cutting down on air conditioning doesn’t mean leaving modernity behind, but it does require facing up to some of its consequences. “It’s not a matter of going back to the past. But before, people knew how to work with the climate,” says Ken Yeang. “Air conditioning became a way to control it, and it was no longer a concern. No one saw the consequences. People see them now.”

Stephen Buranyi is a writer specializing in science and the environment.

Air conditioning is a function of a cold loop that circulates from outside to inside with a working fluid that does not freeze in the loop. On the inside we have fans that blow through the radiator heat exchanger to cool the air. Using the pond as a heat exhaust or dump from the habitats will keep the water warm. having the loop exit the pond to the surface allows for extra cooling before entering the habitat.

The tubing, pumps and control electronics are a business for all to make use of as we will need repairs of the systems once they are installed.

Re: My Hacienda On Mars

We have listed the term greenhouse on the first page 24 times, crops just 3 and yet we have not given it the dues that we need to even thou we have trees and some husbandry.
Most greenhouses would make all plant, or crops while others are used just for the green, green grass to grow within. These are biomes in some cases and life support for others.

Re: My Hacienda On Mars

power is plot 7 in the registry
post 13 mentions the need for backup as a methane versus not nuclear or solar topic.

The fact that a grid does not have sub station or other power source makes for single point failures or at a minimum a zone if breaker'd or fused linked for power line distribution.

Sorry I am off line for the night as power just went out this was posted from a tablet., will drop baçk in tomorrow. Have a good night all.

For the Mars settlement, loss of central power should result in immediate activation of backup systems.
Planning ahead for multiple levels of backup for any locations where human lives will be at risk would seem advisable.
This forum has the luxury of theoretical discussions ... Settlers (or even just explorers) will be in need of actual solutions to multiple levels of problems.
The time to set those solutions in place is while planners have the luxury of theory to toss around.

This is also for SpaceNut, but this time it is a report on complete success by a job holder and a job creator.
Recently, in the Housekeeping topic, I reported an encounter with a service representative for a local electric company, which has the contract from Kohler to service their generators.   My friend who has the generator was inconvenienced by the unwillingness of the generator to start, so the service representative was invited to take a look at the situation.  The problem was speedily identified and resolved, and the rest of the normal maintenance carried out.
What I learned over the course of the visit was that this young gent had been trained at Kohler facilities.  His training came across to me in both my observation of his practice (oil change, spark plug replacement, etc) but in the advice he passed along to the generator owner.  For example, the owner had a mixture of 5W-30 and 5W-20 oil in the emergency supply, and the service representative suggested getting rid of the 5W-20, since the Kohler training had emphasized the importance of ONLY using 5W-30. 
So what I ** think ** I am seeing in this situation is evidence of success of public education systems to prepare this young gent to be hired by the electric company in the first place, and then sent (at considerable expense) to a Kohler facility for factory training.
In the case of Mars, unlike the Earth, which tolerates failure to an astonishing degree, there will be a very limited margin for error.  I expect that every citizen will be expected to pull a full load, much as farm children were expected to contribute to meeting the needs of the family enterprise from a young age.

For mars we can not wait for a power backup to take over if we do not plan them into the grid system. Plus after it does we will still need to dispatch a crew to go out and diagnose the problem in order to send out those skilled to make the repairs to the situation.
Typically grid builders do not have those same skill sets as to those that do the repair.


Plot opportunities:

We have grid builders
Power repair grid distribution maintenance
Robotic grid surveillance and possible control switch activation
Power grid management grid control and power regulating
Backup power sources and excess power storage for backup and other uses

Re: My Hacienda On Mars

For SpaceNut re new Plot suggestions in #187

Thanks for the suggestions for new specialties to be incorporated into the community in development in this topic.

The list of plots has grown to the point that I can no longer work on it in the forum space.  I'm now having to copy it offline and perform searches to insure that a proposed new plot is not already present.

I'll update this post when the work is complete.

Last night's Linux Zoom meeting included discussion of barbering, and specifically the discussion led to "Flowbee" which is listed on Wikipedia, and has its own web site.  The system is understandably out of stock due to the Covid-19 situation.

I'll be offering it as a suggestion for RobertDyck's Large Scale Passenger ship topic.

Edit#1: Power grid and personal care services were added.

Found the post discussion of hair/ barber grooming where the numbers of the military's pool the resources for travel is weighted in a way that many go as the support of the few.

We also have the air cleaning vent system filtration topic Virus filtration killing systems

We also need to make sure that we are able to repair the devices of automation and robotics that we will make use of to reduce risk and eva's that we might need to do in the functions to install, upgrade and repair as needed..

Re: My Hacienda On Mars

For SpaceNut re My Hacienda ... thanks for noting the updates per your suggestions, and for additional links.

It may be possible to find lists of small businesses that have come into existence in various cities/communities over the centuries.

Many businesses have given way as technology advances, but many are (relatively) unchanged over the course of centuries.

***
Speaking of robotics ... (as you were in the closing sentence of #189) ... I went looking for evidence of progress in small agile robotic torso equipment, in connection with the vision of a small robot that could cut hair in the back of a person's head, under the control of the operator looking at a monitor, and operating game controllers or something similar.  Apparently there is a lot of work in progress, but I was unable to find a citation reporting on development of an actual product.  The NASA experiment with a torso robot has ended (I'm pretty sure). 

Here is a NASA pdf about the R1 and R2 robots which were sent to the ISS.  The paper mentions delivery of the R2 system in 2011, and indicates it is expected to remain at the station.

https://www.nasa.gov/sites/default/file … dates4.pdf

GM is mentioned as a partner in development of R2.

That system is pretty much what I'm imagining as a personal haircutting assistant.

Re: My Hacienda On Mars

Here is an image of the NASA/GM Robonaut R2

ONFhMCBb.jpg

This device is shown in motion (In very ** slow ** motion) in videos that are available for Robonaut.

What I'm looking for is a very ** fast ** responsive robot torso that can allow an operator to perform the motions needed to cut hair.

My guess is that such a robot does not yet exist.

Edit#1: There ** is ** a solution ... fast, simple, lightweight, free of complex electronics (except for a web cam).

That solution is a simple mechanical linkage that mirrors the movement of a hand control in front of the operator by moving a corresponding work piece behind the operator.  A web cam mounted on the work piece in the rear would show the work to be done (ie, hair cut).

The whole thing could be down with lightweight wooden rods and pivots.

The Robonaut is actually quite a failed robot as robots go and even Nasa put out a call to fix it.

But yes the right idea just the worng implementation of it.

For SpaceNut ... GW Johnson reported calling Geek Squad.  I'd like to suggest something like that is going to be needed in the My Hacienda community, and not just for digital infrastructure.  The entire enterprise is going to be operating at an elevated level of technology tempo, and there are going to be very few times when (responsible) residents can relax.  Children have always enjoyed a lack of awareness of danger, which their parents and guardians are busy trying to ward off.  Visitors to Mars may enjoy a certain freedom from worry, due to complete and total lack of understanding of the thin veneer of civilization they'll find on Mars.

Last Friday, Robonaut was packed up to get it ready to come back to Earth. As the team in Houston prepares to get their robot back in shape, Badger reminds us that it’s important to keep the overall Robonaut mission in context.

“The whole point of the ISS is to be able to try different things out. I think [Robonaut] has given us a lot of knowledge on what the requirements for humanoid robots in space will be in the future,” she said. “We’re bringing it home, repairing it, and in the near future after that, we’re hoping to fly it up there again to proceed with our original goals of advancing new technology.”

For SeaDragon re #6

Thanks for taking a look at My Hacienda, and for considering this new topic as a place to drop off ideas (or links to videos) from time to time.

The potential of My Hacienda exists in the potential for this forum to provide a place for folks who are serious about building up a civilization on Mars to assemble their ideas and lists of materials and skills.  So far (to my knowledge) we do not yet have anyone working on building a plot, but that could happen at any time.

The "owner" of a plot is the "owner" of a database record in the NewMars database.  What goes into that record is up to the "owner", but it could include everything needed to establish and sustain a business on Mars, in a community of at least 2750 specialties.

The PlotMaster record itself is an example of how a database record can be enhanced and extended over time.  SpaceNut and I have contributed entries as we think of specialties that will be needed, and we have a couple thousand specialties to go.

Edit#1: In honor of SeaDragon's initiative, I have added to PlotMaster:

0082 Vendor #1: Trolley Power Distribution Transportation system vendor.  Provide overhead line for land vehicles.
0083 Vendor #2: Trolley Power Distribution Transportation system vendor.  Provide overhead line for land vehicles.

Re: My Hacienda On Mars

Along with a train and other types of road ways we can include tunnels for the same
I see the Master registry is still growing as desired for all of the settlements and specialties that would be desired for a community to survive and be sustainable mostly independent of earth.

Re: My Hacienda On Mars

For SpaceNut re #197

Thanks for taking a look at the PlotMaster ... it still has 7700 items to go...

At this point, other than your focus on Toehold (ie, (as I understand it) a plot dedicated to surviving on Mars with a small initial crew who decide to take the risk of staying on Mars until the next ship stops by), and my offer of banking services, I am not aware of anyone investing sustained effort in building up a plot.

Todo item: Add water to the PlotMaster (assuming it is not already there) (per Oldfart1939 post from 2017)

Todo item: Add tunnel construction and maintenance to the PlotMaster, (assuming it is not already there).

Re: My Hacienda On Mars

Each settlement will have a mini version of the water reclamation process as part of sustainability for sure.

Plot 3 and 8 will make use of this and maybe others as we will need temporary steps to aid in making things permanent.

Thinking about the roaming expedition mode of early toeholds is a need for a temporary shelter and a temporary garage to  pull a small rover into for the purpose of making repairs and even for the night time use to be able to get out of the space suit in order to same it and yourself from the risk of damaging them when trying to perform work.

This would have a hard panel bottom to lay the Kevlar/ basalt bag onto with tent pole uprights to allow it to be entered and then a sealing system to make the entrance tight.

This temporary structure would be very useful as the community grows.
