    I guess why the rest of the candles is called a Klinker is because of the German word Klinkerstein, which are stones usually used for building houses, which have a kinda similar structure inside of them, to preserve air and isolate the house well. Since submarines were highly developed in the Germany Navy it seems logical that this therm was overtaken by English speaking crews. YAW.

    As usual, an absolutely awesome video--I learned so much! Thanks for all the effort you put into making these educational gems. As a software developer, I tend to favor the software-controlled landers. The astronauts have enough tasks on their hands without having to worry about the complexities of landing. What if the software/hardware fails? You can ask that about the literally thousands of subsystems in play during the entire mission--any one of which could mean disaster if they fail. The answer lies in thorough testing and failover backup systems. Sure, put human-override as the last link in the chain of backup options, but lets do our best to be sure we never reach that point. Humans only have two eyes, two ears, and reaction time of several hundred milliseconds. Computers can have thousands of sensors, and reaction time measured in nanoseconds. And they don't get hungry, thirsty, tired, or distracted.

    Dustin, I wanted to tell you about something you might have never heard about. Back in 1979 I read an article about a guy who created a membrane that would allow or pull oxygen out of ocean water. Its made of plastic with red blood cells mixed in with the plastic. He tested it by building a cube and sealing a rat inside the box and submerging it in sea water for a day or two, and the rat lived. I think the guy was a scientist in Israel, but I'm not sure of this. I think I read this in Popular Science. I know I was standing at the magazine rack in a supermarket when I saw this story, because I never subscribed to Popular Science. Then again it might have been in Scientific American. The article went on to say that the Navy was interested in his invention. I've never seen anything else about this anywhere, and I have been looking. Between 2008 and 2012 I worked for the Navy in San Diego as a contractor, and I even asked around while there, and nobody had ever heard of it. So I don't know if it was really a working thing. It could have been and it just went dark. I would love to know if it would really work. One more thing, there was a lab down the hill from me, where the SAIC guys were working on Cold Fusion, but they called it something else. And they got results and it was posted on DEnewss. Then they shut down the project. Our tax dollars at work.

    We purify water, then we use electrolysis to separate the oxygen from the hydrogen. We discharge the hydrogen overboard and store the oxygen or release the oxygen straight into the air.

    Fun Fact: We are capable of scrubbing the CO2 out of this planet's atmosphere similarly to the way described in this video in amounts equal to or greater than what we produce. We have already built and used facilities to do such, with the largest currently being built in Texas. It is a 1 Megaton atmospheric CO2 plant, which is the equivalent of 14,000,000 trees in that one CO2 plant. It works great and we would only need 40,000 of those facilities across the world to capture all of the CO2 produced on Earth. Sadly all our anti-CO2 funding is going into monetarily inefficient "green ideas" hyped by the mainstream environmentalists funded by certain institutions focused on selfish goals which are not going to help the majority of our people prosper while keeping our environment healthy.

    The Clinkers are named after an old blacksmithing term. When a blacksmith burns coal, some of the coal's impurities cant burn and are left behind, so you end up with a chunk of hard rock like materials in your forge. But when those chunks fall in your forge blowing fan they will "clink" around until settling or falling out.
