Well; I would have liked to continue the thread I started, but I cannot post there after being logged in.
The concept of an autonomous machine is interesting. Now, if it would build an identical self, that would be artificial life.
OK, well, the autonomous machine, and he builds them of cheap material. And he did build. These are not just plans.
There is a fine line between plans and actual structures.
Well, anyways, instead of lecturing, I will go build something.
I will take pictures.December 30, 2012 at 8:45 am #21600December 26, 2012 at 9:37 am #21580
Thank you for the post.
I think, cooperation is important. There has to be others to cooperate.
I think, the more people post is the better.
The ultra low cost platform, in my opinion, is the way to. However, this ultra low cost platform has to be made.
The platform has to be launched, placed in position, and maintained. I would think about an ultra low maintenance
In my case, the food production is easier because I am a vegetarian. It is my direct experience that I can live without
eating any meat. For me meat production is not necessary. I still eat egg, but I would like to quit.
If I may mention ducks instead of chickens.
Instead of soil or hydroponics ; aeroponics, and instead of transporting fresh water to produce it at location.
I would like to mention that there are some distilled water making devices: one just has a cooling element.
On this cooling element water precipitates from the air when the humidity is high. The cooling element is a
Peltier device that can be powered with a photovoltaic solar panel. A Peltier device is often used in a computer
to cool the CPU.December 19, 2012 at 1:30 am #21567
I understand you checked, and you do not see it.
I had similar problems in the past:
I log in, I get to the posts, and I do not get a dialog box.
It’s OK with me. I am happy with this site.
I am happy with what I get. When I want better, I will make a web site myself.
Until then, thank you for your work.
I thought the video was interesting.

COLLISION: BALTIC ACE & CORVUS J
Wednesday 5 December (2012); around 19.20 local time vehicle carrier Baltic Ace (IMO: 9386213, Port of Registry: Nassau, Bahama’s) and containership (IMO: 9262895, Port of Registry: Limassol, Cyprus) came into collision with each other about 35 miles off the Dutch coast in the North Sea near the North Hinder Light Buoy.
The Baltic Ace is a roro, roll on / roll off. Internal structure of the roro is open. There are no separate compartments.
The Baltic ace sank in 15 minutes. Human lives were lost.
I guess, a roro is probably not the best choice for seasteading.December 6, 2012 at 7:48 am #21518
Surfboard-Sized Robot Vessel Makes Journey Across the Pacific
“Just driving up to it in the boat and seeing it there in the water, really having swam 9,000 miles, was pretty amazing,” recalled Hine, the senior vice president of operations for California-based Liquid Robotics, Inc.
“The exciting part is not making it to Australia but the journey in between,”
The wave gliders resemble over-sized Boogie Boards with racks of fins submerge below the surface.
The waves catch the fins to propel the vessel forward, indefinitely.December 2, 2012 at 11:30 pm #21512December 2, 2012 at 11:30 pm #21511
Yes, I agree. Foamed-concrete is good. I am learning how to make foamed concrete.
What are you doing?December 2, 2012 at 11:25 pm #21510December 2, 2012 at 10:12 pm #21509

Yes, porous concrete and foamed concrete is a great idea. Can anyone make it?November 28, 2012 at 9:25 pm #21497November 27, 2012 at 9:07 pm #21494
Some opinions I found on the Internet:
Polystyrene foam is really just polystyrene have been processed to contain pockets of gas (foam). Applying acetone to Polystyrene foam does not melt it, but rather dissolves the material. It is spectacular when applying acetone to Polystyrene foam because the gas pockets collapse, the solvation is quick and a large volume appears to dissolve into nothing.
Though it wouldn’t be easy to accomplish in a home lab, the acetone/Polystyrene foam solution could be processed and re-blown into a foam.November 23, 2012 at 10:51 am #21485
So, the styrofoam:
Well, better call it on generic name: polystyrol.
I got polystyrol chips from packageing material before it was dumped in the garbage.
And I got some seawater. I tried to coat the chips with seawater by immersing them
in a cup. I drained the cup and put it in the microwave oven with the chips in it.
The polystyrol chips did not melt together. I tried increasing the boiling point of the
salt solution by saturating the salt solution with table salt. The chips did not melt.
There might be pressure to increase the boiling temperature of the salt solution to the
melting point of the polystyrol. It would be like a pressure cooker.
I got polystyrol chips for free, and salt water for free. I did have a microwave ove.
So no special equipment was necessary.
I find this interesting. I feel it is more meaningful than watching TV, or playing
video games. (video games can be still better than TV).
I am going to read the patent, and other things, and I will probably figure this out.
I will write about it here.
