For Void re thoughtful, considerate post....
Buried in one of your recent posts was a brief moment of thoughtful consideration of others....
You were talking about the effect of sending matter out the tailpipe of a powerful mass accelerator.
You pointed out that if a human or any sentient being were to come into contact with this material, their defense systems would be tested severely.
The population of Earth is protected (to some extent) by the atmosphere.
By writing this appreciation of your thoughtful post, I am hoping other members might be inspired to think about the issue you've raised.
The only way ** I ** know of to deal with this problem is to use anti-matter pairs and cause them to interact downstream from the exit port of the accelerator. Even then, the energy is not lost, but it ** is ** transformed into radiation, and in that transformation, it appears (subject to correction) that the radiation may be emitted in all directions, so that the risk immediately downstream is reduced.
However, other members may well report alternative ways of dealing with the problem.

For Void re insightful post in Cycler topic ...
http://newmars.com/forums/viewtopic.php … 23#p227223
Your suggestion of using solar panels (and solar sails) for navigation to keep a cycler on course caught my eye as a particularly useful idea. The cycler is going to be collecting a ** lot ** of solar energy to keep it's passengers comfortable and safe, and using those panels for navigation certainly seems appropriate.
The challenge of navigating a cycler is one that might be of interest to future NewMars members.
As you many have noted, GW Johnson is working on course material to help a young human to learn how to navigate in space. To clarify, the existing course material is intended to lay the foundation for later learning that would lead to navigation skills.
I am inspired by your suggestion to consider setting up a topic just for navigation of an Aldrin Cycler.
In asking Google about the Aldrin Cycler, I received back a link to an image of Aldrin holding a model of a cycler.
There does not appear to be a book about the concept, but it may become a book theme at some point.

Thank you for finding and showing this amazing work!
For the first time I understand what Elon and company are going to try to achieve, and how difficult it is going to be.

Just FYI .... today's meeting of the North Houston NSS chapter included discussion of the EPA worry about the water deluge system. While I still think the worry about the deluge system is ridiculous, at least ** now ** it makes a little sense... Apparently the worry is that the fresh drinking water will be heated by the rocket exhaust, and that the ** heat ** of the water that reaches the nearby Gulf of Mexico might cause distress or injury to some marine life.

For Void re Venus cycler ....
Thank you for your interest in and support of the new Venus Cycler topic ....
This new topic was inspired by your comments in other topics. I hope that you and other members will be able to add useful content to the topic, so that it would be worth someone out on the Internet reading from top to bottom.
We do not currently have an active member able to design orbits with the complexity of an Aldrin Cycler orbit as designed for Mars.
However, this forum is accepting new members via the email pathway. If there is a person ** out there ** who is able to plan such complex orbits, the forum would be happy to provide a venue for posts about such orbits.
In a recent post, kbd512 found a summary of comparison of the Aldrin Cycler orbit with two other competing designs. The Aldrin Cycler orbit allows for 7 trips every 15 years, so two such cyclers would offer a trip 14 years out of 15. The Aldrin Cycler design has the distinct advantage of a 174 day flight time at the price of higher energy taxi service at either end of the trip. I think the Aldrin Cycler design will prove irresistible to wealthy travelers for whom time is money, and months saved in transit would be more than worth the extra cost of fuel for taxi service.

For Void re new Windmill topic ...
Best wishes for good health!

Your latest topic contains many ideas.
I'd like to focus this post on just one ....
All existing water collection systems (that I know about) are passive. Humans all over Earth collect water from the air by waiting for the air to bring the water to them.
Your new topic is the first (that I know about) that takes an ** active ** stance....
If I understand the idea correctly, your design would bring the water collection system into contact with water in the air.
What is more, instead of just waiting for air to bring the water, if I understand your proposal correctly, you would encourage the water laden air to approach your location, in order to harvest the water.
A fog bank would seem (to me at least) a ** really ** good place for your system...
All the water in that fog (or most of it) will be lost to humans because there is presently no way (that I know of) to actively harvest it.
Your introduction of turning blades to collect water is interesting, and I hope that your idea inspires others to think about the possiblities.
It will take an investment of energy to drive the blades, and to perform the harvest. I think that point is what Calliban asked about.
This is not an ** energy ** harvesting system, it appears to be a ** water ** harvesting system.

For Void re new post about storing cold as ice....
Thanks for introducing this idea to the forum.
If you are inspired to add possibilities around that theme, I hope you will share them.
One possibility that occurred to me is that ice is a form of water that can be shipped without a pipe.
I note that when see water is cooled, it preferentially puts salt-free ice on top.
There might be something you could do with that observation.

For Void re http://newmars.com/forums/viewtopic.php … 32#p227432
In this post you seem to be expanding upon the ice-as-stored-energy idea.
It was fun to be reminded of a major industry of the not-so-distant past, when ice was collected in winter and sold for refrigeration in summer.
The ice was moved by sledge over the frozen lake surface, and then (I presume) by wheeled vehicle for storage.
To deliver that ice to customers in cities like New York, there would have been a lot more wheeled vehicles involved.
However, in those days, motive power was about as green as was possible at the time....
Where I am hoping you will head as you expand your thinking, is toward delivery of ice to locations on Earth were water is needed, but where Nature does not provide a delivery.
I have no idea where your imagination may take us, but I'm looking forward to the adventure.

For Void re Moon topic ....
I was intrigued by your image of a dome with a hole in the top! I hope you'll keep developing that idea even further.
I was reminded of images created showing rockets descending into lava tube openings.... Your concept seems to have the distinct advantage of purpose built architecture.... Your drawing skills may allow us to see what you come up with.
The reason I logged in just now was to (or at least try to) encourage you to expand your vision of data centers to the Moon.
This forum contains posts about the idea of building data centers in orbit to collect solar power there, and avoid the inefficiency of sending power to the Earth, when that power would just be used for data centers.
In reading tour posts in the Moon topic recently, it occurred to me that the Moon might be much better for data centers than orbit.
For one thing, the Moon has the ability to clear it's orbit.
I'm not wanting to create an argument about a planet clearing it's orbit. I'm simply pointing out that the great mass of the Moon acts to remove small objects that wander by, as compared to the defenseless posture of stations or facilities in Earth orbit.
It is highly likely that unchecked, undisciplined human activity is going to create the Kessler syndrome.
A data facility built on the Moon would at least have the bulk of the Moon to protect it from ** some ** objects moving in space.

For Void re orbital debris collection...
http://newmars.com/forums/viewtopic.php … 92#p227892
Thank you for this interesting business idea.
In hopes of encouraging you to keep developing this line of thought, I'd like to point out that a tether from a large satellite in higher orbit would be travelling more slowly than debris in lower orbit. The advantage is that the difference of velocity would be less than would be the case for a collection system in the same orbit but traveling in the opposite direction (for example). Thus, the debris collector might gather useful material at less cost in damage.
It seems to me that humans do not currently have an organization suitable for managing LEO, but eventually it seems to me likely that one will come into being. The United Nations is the leading candidate, because it exists. Squabbles between Nations are a risk in any scenario. At least the United Nations has some experience dealing with squabbles of various kinds.
However, if an agreement can be reached to remove debris from LEO without provoking conflict, then your idea might have an opportunity to flourish.

PS ... the new FluxBB web site is up and running and ready for members.
I am hoping you will make the time to log in and report if the login is successful, and if things look "normal".
kbd512 has been working on this for over a year, so it is an opportunity for members so help out.
***
Update a bit later ... for Void: GW Johnson often provides us with guidance toward what might be practical. It appears that the Starship as presently designed, does not seem suited for an SSTO flight to become part of a large space structure. However, it appears that if you are willing to tolerate a ride on a Super Heavy, then your basic idea seems (to me at least) quite attractive. I'm hoping you will continue developing your vision of how that might work, and perhaps you can avoid issues of launch by just concentrating on the construction possibilities.

For Void re test post on new FluxBB site!
Thank you for your post! It is reassuring to see a member of the forum take the time to provide positive feedback to kbd512.
kbd512 has been supervising or working hands on to make this new version available for well over a year. We are ** very ** close to having a fully vetted system, so your contribution is helpful!
I am ** still ** hoping someone will assist by logging in and changing the Display feature from Fire to Air or Earth.
We are having a (small) problem. It is not clear where the problem resides.
If a member who has NOT logged into the new system will test the Display change feature, that will help kbd512 to know where to look.
If the feature does NOT work for a member who has not previously logged in, then kbd512 will have evidence leading him one way. If the feature ** does ** work, then we will have evidence leading another way.

For Void re stunning find re "plasma" to make oxygen
Thanks for finding and posting this important research discovery!
A key element your report did not include was that the method involves use of an electron beam.
Humans have been using electron beams in television sets for decades.
It would be great if we could (somehow) find a way to fit this discovery into a topic other than crops.
I'm not sure where it is the best fit, and invite your thoughts.
This method might even deserve it's own topic, but where to put it is a question.
The stunning aspect (from my perspective) is the surprising match of the atmosphere of Mars (composition and density) with the method.
I am hoping our members will refrain from trying to apply this method to other situations. It may be very specific to the competition with MOXIE, and have no value otherwise.
Update: Thanks for putting your report of the new oxygen production method in Life Support systems.
I am wondering if it might be appropriate to create a new topic in Life Support Systems for Oxygen Production.
We don't seem to have a topic with that specific focus.
Here are the existing topics:

MOXIE is a method, as is the plasma (electron beam) method you found.
Do you think a new topic for "Oxygen Production on Mars" would make sense?
Would anyone use it if we create it?
