DIY fridge
You might say "cool". Sorry, couldn't resist the pun.
The actual performance of his device isn't included in this video. That could be interesting to see.
This is of interest to me for its performance in terms of electricity usage. Even a small fridge can pull a lot of electricity. If this one is a better design, then it may be worth considering as a project.
Note: He says that it requires some moving parts, which means more electricity. Also, the follow up test wasn't very informative about energy use, but he did say that he would have a newer version that might do better. Not sure if that means that this isn't very efficient in terms of energy usage. The result is a definite maybe as for making one of these myself.
Purify sea water with primitive tech
A setup similar to this can be employed with a rocket stove, seen in the previous video.
He uses a clay in order to make his stove.
Update:
Another water distillation idea using two bottles.

Doomsday City
Yesterday was an unusual day. For a reason I cannot remember, something made me want to watch a video about the asteroid that is believed to have wiped out the dinosaurs. Something about all this was a downer for me. Why it was a downer is not clear to me.
Later on towards the evening, there was a Star Trek Next Generation episode, called the Inner Light, in which the captain lived a life apart from the Enterprise, and all forty years of that life happened in just 25 minutes. The life he lived was of a civilization that was dying, and he was chosen to be a type of living memorial to their civilization.
It struck me as quite a coincidence for such similar thoughts. Why not expand upon that a bit?
When I went to bed, I recorded a memo to myself about this day. I wanted to see how I reacted to these ideas over night. When I woke up, I had forgotten about what I recorded, but I did remember that I did record something. So, I retrieved the recording, and decided to make a post about something I thought up after making the recording.
The idea was a city that was designed to survive Doomsday Scenarios. The reason for existence of this city was to ensure that the human race continued in spite of a number of these scenarios taking place.
Then I remembered that such a city might already exist. It is a NORAD facility, located inside of a mountain. However, such a facility might not survive a nuclear war scenario, as it would be a prime target for enemy missiles.
However, in case of a massive asteroid strike, such a facility could allow a small population to survive for a time. The thought occurred to me, could such a facility be useful for a long term stay of indefinite duration?
Could you grow your own food, process your own wastes, and live outside of the biosphere? Such would be the necessity if the Earth's biosphere is shattered by an asteroid strike. A similar situation would occur if you were to attempt to colonize Mars, or the Moon. Therefore, why not re-purpose a facility to do research like this? Would it not be valuable? In case of the objections of the defense establishment, an entirely new one could be constructed.
A thought that an Ice Age could occur, and the place could become iced in. Such would entomb the survivors forever, or until the ice sheet melted. Therefore, the place could be in a tropical location, far away from any possibility of icing over.
Would such an idea ever catch on?
Update a little while later:
The idea here was not dissimilar to the Biosphere experiment, but different due to its proposed scale and purpose.
The Biosphere project could be useful in studying ways to survive long term in an environment that is closed off from the rest of the world.
Another update a little while later:
The Chinese have their own system, and they ate mealworms in their experiments. They tried this on American space missions, I read, but the astronauts resisted. ( lol )
Interesting links here. Bottom line is that such a system as I envision is a very long way off.

Snake trap that works
Made from soda cans, tape, string, and some hacksaw blades.
Wonder what the dude did with his snakes. He caught two. One of them looked like a poisonous variety that wanted to bite him when he approached.
Check it out. I wouldn't think that he would eat them, but who knows?

Growing Spirulina
There may be another post on this in the first volume on the other blog. Let's just call this an update to that.
It looks simple enough to do on my own.
He provides a link on where to get the "x" system. Oops! The link doesn't work anymore. Oh, well. There are probably other providers. Let's hope so. You don't want to depend upon something that goes away.
He has his own youtube page, which still works. I don't see one about spirulina, though. He has an endless number of videos. It seem unmanageable to me.
Anyway, I think I'll look for another source of information for spirulina, although this guy seems knowledgeable enough. Here's the next one I looked at: how to grow spirulina at home.
Spirulina may have lost favor somehow. It doesn't seem to be easy to find these people. Oh, well. Another idea may have to bite the dust. Wait, I found a link at Amazon. Expensive, though.
Update a few hours later:
Here is a more recent video, with some hopefully useful links included in the comment section.
Note: They do indeed appear helpful.

off-grid post 3.24.19, concrete ideas
The main idea now is to simplify things. Here's a possibility: a 6" wide by 4" deep concrete connector would run between the posts. In other words, the posts would be connected all around with reinforced concrete. This would make the structure more rigid, and hopefully, more stable in high winds.
The advantage to this idea would be that it would take a lot less concrete than a 640 square foot slab. Or even a smaller slab for that matter.
Such a connector could be built in a week or two by yours truly working alone. Maybe another week to dig out the post holes. Finally, a third week, I could have all fifteen posts in place. This looks like a feasible project.
From that point, I would have something to build upon.

SpaceX's Crew Dragon splashes down successfully
Another feather in the cap...
Successful splashdown of the #CrewDragon right on time at 8:45 a.m. ET. pic.twitter.com/0qHhHzD4Js— NASA Commercial Crew (@Commercial_Crew) March 8, 2019

How interesting
The artificial gravity equation is as follows:
This means that a spacecraft can simulate gravity by spinning at a certain rpm. The interesting thing is that if you spin up the SpaceX's Starship to 6 rpm, you can achieve 1 g, or Earth's gravitational pull. That would mean an area at the ends of the spacecraft would experience 1 g at 6 rpm.
One of the knotty problems that needs to be solved in long term spaceflight, is the human body's poor reaction to weightlessness over long time periods. If you were to find a way to simulate gravity, perhaps you can mitigate this problem. ( or eliminate it )
One possible objection ( no doubt that there are others ) is that the rotation would have to be end over end. Could this affect maneuverability? If you have to dodge something, can you move? Can you make mid-course corrections?
