Uh we got the hottest June ever and the first period of 12 month, where every month was above 1.5°c compared to the pre industrial time. But yeah, no worries. All good. Just keep doing what you're doing!

So do you want just the name and then do some googling yourself or a one/two sentences description of what the label represents? Do you want just the TARDIS or also a picture of the flag I worked off of? Do you want them as chaos or alphabetically or like sorted by umbrella labels? What do we feel?

Hey #queer and not-queer-but-ally community.
I've just finished the last flag in my list (which is not exhaustive at all) and I'm now trying to plan how to put these into the world.
Most specifically, which information would you'd like to get with your queer chaotic TARDIS.?

Love how the last two show runners just looked at 11 and thought Nah. Let's make it make LESS sense. Apart from that I really do love the new episode and season of doctor who! Ncuti is a great doctor!

Hey. Do you like TTRPGs? Would you consider yourself to be at least a semi-decent human being? Do you have $10 left? Then why not head to itchio and get yourself a wonderful collection of OVER 600 TTRPGs :) All proceedings (close to 150k right now) go to the Medical Aid for Palestinians :)

And apparently, because the explosion of the underwater volcano in Tonga in early 2022 pushed so much water up into these higher levels of the atmosphere, this year we have a higher chance of getting these clouds and they could be brighter ☺️

Noctilucent clouds are the highest clouds on our planet at 85km up! You can see them sometimes just after sunset when there's just a little light left. They are made out of tiny ice crystals, which reflect this last light. You can almost exclusively see them close to the polar regions. (1/2)

(25/25) if you want to use this in your story: -make steam hotter, more power -increase the amount of steam, more power -shrink down the size of the second cylinder, more power (too hot, too much or too small and your engine goes boom, though)

(24/n) And because in this version you have more reliably linked the steam distribution and the piston, it's more reliable and easier to handle, which is why you can use it to power a locomotive or whatever else you want :) It is more complex and you really need good manufactured pieces, though

(23/n) Using the numbers from the youtube video again, while in the first version you relied on air pressure (one small car on your head) with this super heated steam you get about 80 small cars on top of your head of pressure.

(22/n) So now you have a system, where the piston is being pushed back and forth by this super heated steam, and because you attached this to a wheel instead of just a string, you can put it on the side, while not loosing any of the efficiency. And this super heated steam is also much stronger

(21/n) because at that point the smaller piston is on the other side of the smaller cylinder, the steam flow is now diverted to the other side, so once you've pushed the larger piston away, you can get rid of the excess steam on your side, while simultaneously building the pressure on the other side

(20/n) this means that you now have a very small space that is rapidly filling with steam AND is getting smaller. This builds up the pressure inside of this second cylinder, and when this get's larger enough this will push the piston back to where it comes from.

(19/n) depending on where in that cylinder the smaller piston is, this super hot steam is now redirected to either one of the two ends of the larger cylinder. while this is happening, the larger piston in this larger cylinder is also moving towards this steam.

(18/n) as opposed to version 1, where you'd have the steam going to the tube and then cut of the steam flow, here you have a constant flow of the steam. So this super hot steam is now coming in through the little hole in the smaller cylinder and fills up that space.

(17/n) In this case this is done by having the water flowing around the boiling pot. So you can constantly boil the water and then the steam is also still very close to the hot boiler, so it will stay hot for a long time. This means that there is (a) A LOT of steam and (b) that steam is VERY HOT

(16/n) Cool let's move on. We'll come back to the piston layer of this steam engine later, let's go a level down to the water heating and steam production part of this engine for now. For all of this to work, you need a lot of steam, that's very hot.

(15/n) interlude: please be aware that the actual layout is more complicated. I do recommend this video by animagraffs, which shows this very well. Interlude 2: historically, this came later, because it needs very precice machining. you can't really have too much space for the pistons to move around

(14/n) This way, when one piston is at the front, the other is at the back, and then when the first is at the back the second one is at the front. The small tube has one hole where steam is constantly flowing in, and then two holes to the larger cylinder, one at the back and one at the front.

(13/n) Okay, so for this steam engine design, we have two chambers that sit next to each other. one larger chamber with the piston you want to move, and then a smaller chamber, with a smaller piston. You would connect both pistons to the same wheel, but on opposite sides.

(12/n) In version one the piston you moved was what provided power, so having this extra thing now is a good thing. Because of some weird less important physics things we won't talk about now, you'd use a large wheel to make your machine run smoother, less shaky, and more continuos.

(11/n) the very basic advantage of version two is that it uses steam on both side of the piston, to both push and pull it. The piston itself is also now attached via a metal rod to a very large wheel, which it is rotating, and then you can use that rotating wheel to power whatever you need to power

(10/n) This is terribly ineffective. You loose a lot of the energy in a lot of places and because you are attaching the piston to a string, it can only really work for things to pull, which makes it very difficult to put it on it's side and make it fit more places. That's where we get version 2

(9/n) This then pulls on the string, which moves the pump or whatever you have attached to it. Once the piston is back down you can open up the connection between your water boiling pot and the tube, so new steam can flush in and you start the cycle anew.

(8/n) This might not seem like much, but on the surface, that's about a small size car balancing on your head all the time. Because we have now created an area of low pressure inside of the tube, this air pressure from outside can now push the piston back down in the tube.

(7/n) if you remeber from earlier, steam takes up more space than liquid water. So when we turn the steam back into liquid water, it now takes up less space. This creates an area of lower pressure, called a vacuum. On earth, we are constantly surrounded by air, that is constantly pushing on us.

(6/n) in the very early versions, they sprayed the whole tube with cold water, later on they put an extra thing in there to just spray in a bit of cold water, instead of the steam. This cooling down turns the steam inside of the tube back into liquid water.

(5/n) when you get enough steam, that pressure is enough to move up the piston in this tube. Once the piston is at a certain point, you close down the access for the steam to the tube. Now you have a limited amount of steam in your tube. Next you need to cool down the tube.

(4/n) This piston is then connected via a string to your pump or the thing that needs energy. here's who it works: you boil the water, which creates steam. The steam needs more space than the liquid water, so it rises up to the tube, where it is blocked by the piston.

(3/n) The first one is the simplest one, and the first one to be invented. it's not really powerful and mostly good for pumping water from mining shafts. It has a pot of water hanging over a fire. on top of this pot you have a tube. inside of this tube is basically a metal plate. that's your piston

(2/n) There are 2 main kinds of steam engines. The first one uses steam to push a device called a piston, that's used to transfer the energy to something useable. In this case a string attached to a pump. The second one uses the steam to push AND pull the piston. which is used for trains and stuff

Science of Steam engines. this is from a "Real engineering" and "animagraffs" youtube video and about 30 minutes of research, so keep that in mind. if there are any actual experts out here, who wanna help, please feel free to add :) With this disclaimer out of the way, here we go:
