Had a sore throat last night, went to sleep with one of those Vitabay 50mg's in my lip like a Zyn. No sore throat in the morning ¯\_(ツ)_/¯

If someone were to read ONE of his books, in order to get a superior understanding and appreciation of what he contributed, which one should it be in your opinion?

Extremely erudite thread. 10/10. And then you've got Funny Guys like me making the problem more difficult on purpose...

Nobody Understands Leyden Jars. A leyden jar, for those who have never seen one, is a rudimentary capacitor made from a jar and some metal foil. In the early days of electricity research, they were commonly used for storing static electricity. In the famous Ben Franklin kite experiment, he was said to have stored the static collected from the air to a leyden jar. Normally, they're pretty simple devices, they have 2 conductive plates (foil) separated by an insulator (glass), that's your classical capacitor. What makes absolutely no sense is the fact that when you fill one with water, it's capacity for storing energy increases *dramatically*. Based on typical electrical understanding, this is a total mystery. The water is not completing a circuit that goes anywhere, it's not even acting as an electrode because (as you can see in diagram 2) there is foil between the water and the glass. The water seems to be connected to a dead-end of the circuit. The reason why water affects the leyden jar is because electric fields cause water to polarize (fig 4). All of the hydrogens begin pointing one way, and all of the oxygens begin pointing the other. The water doesn't "want" to do this, entropy drives it toward random alignment. Polarization actually causes a small amount of heat to be expelled from the water, and relaxation (discharging the jar) causes a small amount of heat to be absorbed as the atoms go back to bouncing around at random, this is called electrocaloric effect. This is one thing, and it explains why water has such an effect on leyden jars, but when there's an electrolyte like salt in the water, things get even more interesting. Common table salt is NaCl (sodium chloride). Dissolved in water, we're told, the Na+ and Cl- disassociate. Though they're no longer chemically bonded, they have opposite charges so they don't move far apart from each other. In classical electrolysis, you apply electricity across two plates, pulling the Na+ in one direction and the Cl- in the other. Then electrons split H2O into H2 and OH-. Were it not for the Na+, the entire reaction would stop before you noticed anything, but because Na+ is happy to sit next to OH-, Cl- is free to walk across the cell to the other side, where electricity does one of two things: Either evolve Cl2 (chlorine gas) or else O2. Now this little detour into electrolysis is important because the first step in this process is actually happening in a leyden jar. If you have a salt water leyden jar, and you charge the outer plate negative (water is positive), the Na+ is drawn toward the outer edge of the jar while the center of the jar becomes Cl- rich. If you charge the jar and then draw water from the center, you will get Cl- rich water. If you then discard the remaining water and put back the Cl- rich water and charge it again, you will get even richer water. You can easily imagine a cascade of this construct making arbitrarily strong NaOH (sodium hydroxide) and HCL (hydrochloric acid) simply by doing the same bias over and over again. Indeed a 2020 paper ( https://www.sciencedirect.com/science/article/abs/pii/S0011916419312937 ) showed that exactly this trick can be used for desalination of sea water - because as the NaOH and HCL become more concentrated, the intermediate water obviously becomes less salty. But what's really interesting is that this isn't constrained to Na+Cl- ions, ALL ions in water would be drawn out by this cascading construct (including fluoride), so it could be used as an alternative to reverse osmosis filtration. But even fresh distilled, deionized water has ions. These are "intrinsic" ions of H3O+ and OH- which spontaneously emerge. The reason why these ions are insufficient for electrolysis is because there aren't enough of them, and while electrolysis does make more of them. 2H2O + 2e- -> H2 + 2OH- and 6H2O -> 3O2 + 4H3O+ + 4e- produces OH- and H3O+ respectively, but they tend to walk across the water and cancel each other out, bringing us back to our problem of ion poverty. However, if we were to concentrate the intrinsic ions, we would have H3O+ rich water, and OH- rich water. These would both make very good electrolytes if we wanted to make hydrogen from water later on. All this from lyden jars - which nobody understands.

This is a really interesting idea:

I wouldn't do exactly what they're doing, but I'd do something close: Namely you take a thin sheet of steel, and you coat it with photoresist, then shoot it with a low resolution (simple, cheap, home made) photolithography device. Then you wash off the photoresist to get your pattern, then you put it in an electroplating bath and start adding metal. Metal can only be added to metal, it can't be added where the metal is covered by photoresist. Moreover, once the height of the plating is higher than the photoresist, it will start to close over the top and bridge. So if you make your channels very narrow, you might close over in less than 1mm of material added. Electroplating is not that slow, you can probably add 1mm in 24 hours. Once the process is over, you probably use heat to melt the photoresist and then pressure to drive it out of the channels. Then you can wash the channels with solvent to get whatever photoresist may remain. Good way to make micro-channel heat exchangers, or anything else that requires liquids to flow through lots of very small pathways.

Zinc update: Had a mild sore throat today, popped a Zinc-50 Depot in like a Zyn about 3 hours ago, still not entirely dissolved but that sore throat sure is gone...

China's gonna figure out how to stop viral replication... Some kind of "get zinc into the right cells fast enough" type chemistry. And at that point both viruses and vaccines will be obsolete. And the west will (in their normal fashion) keep making vaccines and denying that it exists until their situation becomes so dire that they cannot continue any longer.

*sigh* Just invented a variable pitch propeller hub. These are typically 10-20k$ systems and my design has no oil, no seals, no pressure, no roller bearings, you can just throw grease in it. Probably 500$ to manufacture. And I'm *extremely* confident that it will have absolutely heroic strength and vibration properties. Should I chuck in a patent application and see where life takes me, or should I dismiss it as head-noise? ¯\_(ツ)_/¯

I love how everybody's all about fedposting... But then the second I bring up The Thing, everybody gets quiet as shit.

They can't take recover a state snapshot? 👀
