Here is another "very good idea" by Terraformer .... this came from the Thermal Energy Storage topic ...

Terraformer wrote:

Hmm. Perhaps thermal storage would reduce the size requirements for heat pumps, if they operate continuously whilst heat demand is discontinuous? I.e. people only having the heating on for six hours in the evening could allow a significantly smaller ground loop if for the other 18 hours the heat is being banked.

Here is another noteworthy idea from Terraformer ...

For personal vehicles, how much range is actually needed under its own power? For long distance travel, there's no reason a train can't be used to ferry them. Or even medium.

I have long thought that the basic idea, of carrying one's personal transport vehicle along during travel, makes a lot of sense. Wealthy folks have been doing that for millennia ... In the modern age, it is within the realm of possibility for an Uber-like company to offer an automated vehicle transport service. I would use that if it were available, so as to reduce wear-and-tear on my personal vehicle, while enjoying the convenience of having that vehicle for use at the destination.

This idea might earn a topic of it's own, if a member so decides.

I'm not sure who responded to my question about aluminum for trolley lines ...

It might have been Bing ... I'm on a Windows 10 machine at the moment ...

Yes, aluminum is suitable for overhead trolley power lines. Aluminum is the all-around best material for overhead cables and utility pole because of its unique properties. With its small density, low price, and high electrical carrying capacity, an aluminum wire is perfect for long-distance lines12.
I hope that helps! Let me know if you have any other questions.

Calliban brought the topic of Roads on Mars back into view recently.

Out of curiosity, I went back and read it from the top until I hit this!

Which one are you entering?
I would like to start up my own R & D team, so I've been looking at the X-Prizes for things to enter. I'm only 13.5, but who said there had to be an age limit for inventors and scientists? I think I've cracked the problem of how to build a hoverboard/car. Efficiently, that is.

This forum was indeed fortunate to attract a member of that age! JoshNH4H and other members were in college at the time they were active.

For Terraformer .... thanks for following up with Calliban on the interesting ideas in play ....

It's been a while since you checked in with the forum, and without putting any personal information at risk in this public place, can you provide a hint about how things are going? I ran across one of your posts from years ago when you had just acquired a Blackberry. It was then a state-of-the-art device, and I understand it may still be in use.

For Terraformer .... thanks for stopping by occasionally ...

FYI ... Dave Z has posted recently in the Knowledge Forum .... He and his partner Anke produced a series of films/videos about their travels in Alaska. I'm trying to encourage him to post links to the videos in the Knowledge Forum.

A while back, you reported on communication with an ? elected ? official about a renewable heating/power concept. I assume that if you'd heard anything more you'd have reported to the forum. Please consider pulling that chain, to see if anything falls out.

I'm expecting not, but am prepared to be surprised.

For Terraformer re discuss.the-knowledge.org ....

Dave Z got around to replying to your post of July of 2023. I'd like to invite you to consider developing a body of work on your Ceres theme at Dr. Dartnell's forum.

The forum is visited daily by all the major search engines. That was a feature Dr. Dartnell installed when he created the forum.

You and Dave Z and I are the only active visitors to the site.

Dave Z and his partner Anke are residents of a small village on one of the many coasts of Alaska. He and Anke prepared a series of videos about their sailing adventures in the open waters around Alaska, and links to the videos are provided in the Transportation topic.

In his most recent post, Dave Z has given up on trying to convince you that an O'Neill habitat would be a better investment of time and energy than your idea of building inside Ceres itself.

In pursuit of your studies of ecology, Dr. Dartnell's forum offers a place where you can explore your ideas and "publish" to the extent you want to do that.

Dr. Dartnell's site is stable, so a link to a post in that site can be given to another person as a reference.

With regards to the options .... it seems to me that it is not clear at this point, if it is going to take more or less energy to build an O'Neill habitat vs building inside Ceres. Both options will require a ** lot ** of energy, and a lot of work, although in both cases, most of the physical work will be done by automation.

For Terraformer re Heat Pumps discussion with Calliban ...

https://newmars.com/forums/viewtopic.ph … 49#p219749

I see an opportunity to (at least try to) encourage you to develop your ideas about ceiling panels ...

You've indicated that you think the price of 100 pounds per square meter is high, and from my perspective, I have no idea what would be a fair price.

What I'm sure of is that anyone purporting to be qualified to do that work will have a pretty good idea of what costs I know nothing about may be in play.

My guess is that the material costs are a minor part of the overall job costs.

If my inquiry inspires you to investigate, I would be most definitely interested in your results, and hopefully one or two other forum members might be as well. The overhead heating system that Calliban proposed, and to which you have replied, would seem (to me at least) ** really ** useful for Mars.

Calliban is working on a concept for cast iron struts for geodesic domes to hold regolith overhead on Mars. He can design the domes so they are tall enough for heating and lighting fixtures, and your work might show us what those could look like.

(th)

Calliban · 2024-02-24 17:18:12

A ceiling mounted heating panel is a non-optimal heating arrangement. It would require a recirculating fan to work, because hot air rises. Without forced convection, the convective heat transfer coefficient will be poor. For existing houses in the UK, it may be a better option that tearing up floors and rerendering walls. But if we are building a structure from scratch, then there are better options. When the dome is completed, covered and pressurised, the internal structure can be built using adobe bricks, stone, mud mortar and iron beams. We could embed heating pipes in walls and under floors. If this is done, then the entire surface area of a room becomes a heating panel. The advantages of this are twofold. Firstly, with such a large heat transfer area, the pumped heat temperature only need be marginally hotter than the desired air temperature. Secondly, the masonry structure will store heat. Both attributes are valuable.

For Terraformer re renaming or editing a topic ...

It took a number of years for me to discover that you (the topic creator) have the power to revise the title of your topic.

Just go to Post #1 of the topic, and you'll find that the title is available when you edit #1.

It occurs to me (as I think about your new topic) that sea level rise may be worth considering as you develop the topic. The ocean may fill in spaces you (or your friends) might create on land ahead of time.

For Terraformer re waste of photons ....

https://newmars.com/forums/viewtopic.ph … 85#p220485

In your reply you changed the scope of the problem ....

Or, more accurately, from my perspective, you *** seemed *** to be changing the scope....

I was calling attention to Void's assertion that photons falling the ocean where there are no nutrients are "wasted"

My immediate reaction was that if the photons are not reflected to space, then the are not wasted.

My impression is that Void was thinking of photons not used in biological processes as wasted, but from my perspective, most photons have other job assignments, and that would clearly be the case in the "desert oceans" Void was talking about.

If you are so inspired, please develop your thinking about "wasted" photons a bit further.

Since you are the only other member of NewMars who has access to the Knowledge forum, I'd like to let you know I've opened a topic about Asteroid mining there, based upon the idea of our Alaskan correspondent to inject material into a rubble pile so that it will freeze around some of the material.

For Terraformer re latest post in Synthetic fuel topic...

http://newmars.com/forums/viewtopic.php … 64#p221364

Thanks for this interesting and timely addition to the Synthetic fuels topic.

Calliban and kbd512 have both advocated for solar trough systems, and Calliban just posted another endorsement of the concept.

We do not have any investors in the current membership (that I know of) but Spaniard at least appears to be in communication with one or two.

The project you've described in your post ought to appeal to a capitalist willing to take a long view.

Using solar power to make ammonia and shipping it to where the customers are seems like a practical idea.

What seems to me is needed is someone able to put words into actions that lead to a successful business that turns a profit in a reasonable time.

Three years seems to short to me, as a typical payback expectation, but ten years might begin to look reasonable.

For Terraformer re new topic ...

Under SpaceNut's leadership, this forum has introduced some changes ... some are major, such as shutting off the spammers and adding the recruiting service.

Some are minor, like using Sticky's more than some folks like, but which I find helpful.

In this post I'm offering you an opportunity to manage your new topic.

This will require the cooperation of the two Admins and two Moderators, but there is a fair chance that will be forthcomng.

I'd like to invite everyone to contribute to your topic in a way that has a net positive effect.

We have a long history (over 20 years) of individual members objecting to something and failing to provide a solution.

In the case of your proposal, I know from observation that the negative posts are just waiting to pounce.

You have the option of asking for a post that is not helpful to be moved, or to ask the creator of a post to edit that post until it meets your requirements.

Please reply with your guidance on this subject.

If one of our two Admins creates a post, we will have to try to persuade the Admin to make changes.

It is against human nature to admit fault or failure of any kind, so it would be best if posts do not have to be changed.

Please post guidelines for the topic in Post #1, which you can edit as needed.

I'm happy to report that Dr. Dartnell replied to my report of hacker activity at his phpBB web site.

He just published a new book so I'll be ordering it shortly.

He's a potential ally in your initiative to engage Calliban to design a mass energy storage facility for your town.

I have no idea, but he might favor London?

For Terraformer re thermal energy storage ....

Is

Carnforth

a suitable candidate for the experiment?

***
Please take a look at phpBB3 in the demo site... I can create a category for your project. While this is ** only ** a demo site, it can provide a model structure to show to SpaceNut, who has the ability to re-create the structure here, if folks like the idea.

One advantage of the demo site is that it is currently empty of content, so you could invite community members and community leaders to meet there to discuss a possible path forward, without the distraction of 20 years of content in NewMars.com/forums/

Can you and Calliban agree on the overall scope of the project? Calliban seems to be offering the opportunity to make some sizing decisions, which would be helpful in securing support.

Calliban has offered wind power as an energy source. Is that an option in the community of interest? Would there be opposition based upon aesthetics?

Would there be opposition based upon other factors? Human beings are good at opposition !!!

https://newmars.com/forums/viewtopic.ph … 55#p222355

Thanks to Calliban for finding and postings this report on a huge heat pump at a Danish city.

While the engineering is impressive, I am far ** more ** impressed by the leadership demonstrated.

A single individual had the vision to inspire the investors and countless participants to bring that system into existence.

That single individual had the mental strength to ignore the naysayers and deep doubters who were inevitable present in great numbers.

That single individual had the stamina to hold to a vision despite countless setbacks and headwinds.

We video viewers are now privileged to look in on the end product of that single individual's persistence.

The heat pump for an English town is going to require that level of leadership.

The NewMars Large Ship will exist some day, in some form, and it will exist because a single individual had the stamina and persistence to see it through. In the case of the a few of the great European cathedrals, leadership passed through several generations before the work was finished.

If an English town ever finds itself heated year round by a system that does not rely on fossil fuel, it will happen because a single individual had the strength to resist the countless naysayers and Debbie downers who live in England, and around the planet.

Frugality and Abundance are not incompatible...

It seems to me it would be advantageous for your developing concept if you provide citizens with the prospect of comfort as an alternative to privation.

If you can do that with a thermal store of some kind at the home level, and the amenities that are thought to characterize civilized living, all the better.

The average person is likely to be content with modest circumstances, if those circumstances were to be considered civilized by modern standards.
