  1. ..and the volume of heated liquid tends to increase as the temperature increases..
  2. ..be prepared for the worst..
  3. Buy a 3d printer and you will print whatever you want or design yourself.. including yet another 3d printer or machine to make free filament from used PET bottles that you foolishly throw in the trash, for example:
  4. The only really expensive part from my list is electronic vacuum pump. It is here for 300-500 USD. But it can be temporarily replaced by water vacuum pump (aka "water aspirator"). Ultra cheap. Like $5. I could 3d print it for 0.1 USD.
  5. Distillation of beer (<=6%), would give you very poor yield.. I used extremophilic yeasts capable to survive up to 21.3% (I managed to have 19.5-20). https://www.google.com/search?q=extremophilic+yeasts How often do you distill beer? Have you ever try to make beer? The whole procedure is completely different.. ..because it is already distilled.. @Moontanman If you want to have good quality get chemistry lab equipment. borosilicate glass. graham condenser. dephlegmator. vacuum distiller (for final, 3rd pass). https://www.google.com/search?q=graham+condenser https://www.google.com/search?q=dephlegmator I have similar to this, which is a mixture of both: Distillation lab equipment often has a built-in thermometer, so you can see if that's the temperature at which methanol and other crap evaporates, or ethanol.
  6. 129 L per second flow * g * height = max power you can get from it. This does not look impressive. In rural uninhabited wasteland - acceptable. However, they would get more from solar panels on the roof.
  7. Most of humanity is blind without drinking methanol....
  8. Stop writing "Russia did this", "Russia did that". It is V.P. and his minions, who are responsible. The average Russian has no influence nor desire to participate in this evil madness.. If I were an average Russian sent to fight Kiev, I would rather like to go for Moscow..
  9. ??? Density of ethanol is 0.789 g/cm^3. Density of methanol is 0.792 g/cm^3. (and varies with temperature) Good luck checking it out at home.. Methanol and ethanol have significantly different boiling points.
  10. Ukraine has good engineers - the Antonov the world's largest aircraft is their product, so if they wanted to, they would make missiles capable of this.
  11. Vector field can be simulated with three scalar fields.. It is just a matter of adding a couple properties per spot. If you don’t understand, it is magic, for you.. Once you know, it is no more magic, but knowledge..
  12. When you distill something, you must slightly exceed the boiling point of the substance. Check the ethanol chart, and you will have the answer to your question..
  13. Different states have different regulations. https://www.ncsl.org/research/financial-services-and-commerce/home-manufacture-of-alcohol-state-statutes.aspx "In 1978, Congress enacted Public Law 95-458 (H.R. 1337), amending the Internal Revenue Code to allow any adult to produce beer, without the payment of tax, for personal or family use. The beer produced per household may not exceed: (1) 200 gallons per calendar year if there are two or more adults residing in the household, or (2) 100 gallons per calendar year if there is only one adult residing in the household. " "Under 27 C.F.R. 24.75, adults may produce wine for personal or family use in the same amount as allowed for beer." (wine can have 3-4 times more ethanol than beer)
  14. Sugar does not contain the nitrogen needed for yeast growth. People add some raisins for example.
  15. "Before you can run you have to learn to walk".. "and before you walk you have to crawl".. i.e. start making simpler/basic chemical experiments, get lab equipment, learn how to separate mixtures of compounds, get ball-n-stick models to reproduce chemical compounds etc. etc.
  16. ..then maybe get to university first.. Chemistry, or quantum physics or so..
  17. @studiot Didn't you notice that politicians don't answer reporters' questions?
  18. Looking at the statistics of who is the largest producer and exporter of weapons is, of course, the most developed countries.. These are not "resources".. They are remains of archaic cousins of man and all living creatures.. squeezed by pressure, degenerated by temperature.. The amount of regulations and invigilation level you have in democratic countries is beyond imagination of the "politicians" of totalitarian states that existed centuries ago..
  19. I already said decades ago "winter is coming".. They had more than enough time to prepare.. You don't start preparing food and shelter for winter when you see snow, but you have to do it in summer.. Democratic politicians think only about how to win the next elections. In U.S. even more than in EU - 2, 4 and 6 years terms (replaced every 2 years 1/3). When one complain ends, new one is already in progress.. They think of nothing else but "how to stay on the chair".. The result is senseless, stupid, legislation like e.g. "web cookies" & "unsubscribe mail address" (which resulted in ultra happy hackers and defrauders), "fossil tax" (which resulted in ultra happy financial sector and investors who can make yet another frauds on yet another financial instrument).. If ordinary people were well-educated scientists, politicians would have to listen to them to get elected, and "global warming" would not exist in a few months.. the all resources used to build crap like tanks, warships, warplanes and the all other weapons would be used to build solar panels and other renewable resource.. Countries that rely on the production and export of fossil fuels are in desperate straits, resulting in what you see this year.. In the local stock market, investors have an adage "even the dead jump up" (which is used when a company's share price goes bankrupt)
  20. What for? Humanity should give up on fossil fuels.. and use them only minimally..
  21. More important was his death.. And the death of his mother.. and homelessness.. Who wants to jump into such a parallel Universe with up-to-date knowledge from this Universe World War II would have been very different.. That's why I'm here.. ..unless there is total determinism.... (caused by an error in the random number generator code...).
  22. The same way as you enabled? https://www.google.com/search?q=activex+windows+10
  23. You think and take Russians as if they were like US or European citizens.. They have been indoctrinated and brainwashed since ~ 1917.. Grand-grandparents, grandparents, parents.. all lived in fear of being sent to the gulag, shot, arrested, tortured, living without contact with the rest of the world. A little thaw in early '90 won't fix it in their brains. They are like slaves. Robots. They have been trying to survive in a hostile environment for a century. Those who have escaped brainwashing have already fled Russia whenever they can.
