OPEN THREAD 20191117

Basically, all legal free speech is allowed. We will assist the authorities in dealing with illegal speech. You are each other’s moderators. Have fun. And don’t forget to MAGA at nuclear levels.

Citizen U

PS – today – the Qth of November, is DAY 11.

The 11th element is SODIUM. https://en.wikipedia.org/wiki/Sodium

Like fluorine (atomic number 9, atomic weight 19), sodium only has ONE stable isotope – 23.

https://en.wikipedia.org/wiki/Isotopes_of_sodium

You can see that the number of neutrons is starting to gently exceed 1/2 of the nucleons in the stable nuclei. This trend will continue in our presentations in the open thread, as the atomic number and atomic weight increase.

Sodium metal is interesting stuff, and is frequently used in colorful, pyrotechnic, scientific demonstrations.

Don’t flush sodium down the toilet!

And don’t forget to….

ENJOY THE SHOW!

    1. love yr flicks as openers here…big movie fan myself…much more so in the past, for some reason, than I am with the mainstream movie industry these days…love the oldies 😀

      I used to be an animator…the old “Disney” style before computer animation…. cel animation …2D animation where each frame is hand-drawn on paper then hand-inked onto sheets of plastic called cels …this was the dominant technique until the early 80s when computer animation started to replace it….unfortunately…altho I am beginning to develop an appreciation for digital work, finally, after almost many yrs of not..

      anyway….here’s a little doc from 1938 on How Walt Disney Cartoons Were Made, using the traditional cel animation mentioned above…

      1. Congratulations, Smiley.

        You were part of a golden age of animation long gone.

        I am not a Disney fan, but appreciate the detailed creation of the cels and the animation, pretty much universal throughout animation houses then.

        Of note is the background design creator, smoking a cigarillo. 😉

  1. Some of the classroom demonstrations that have done me the most good in life were done with simple apparatus that was destroyed in the process.

    Things like, “never use water to put out a grease fire” (cause grease fire over bunsen burner, use water pistol to put it out); or “why do people still remember the Hindenburg?” (Float large hydrogen balloon over bunsen burner).

    My grandfather was a movie projectionist in his youth, before “safety film”. Originally, the backing of movie film was celluloid…….also known as nitrocellulose……also known as guncotton or “smokeless powder”. Every year the fire department would pick a large empty lot, and put a reel of surplus movie film in the center, and pull a length of film out to the edge of the lot, wait until a crowd gathered, then light it.

    Old-style movie theaters always had small windows through which the movie was projected. That was to limit the amount of explosion that would go into the audience. By contrast, the wall between the projection booth and the street was relatively lightly built. To add to the fun, projectors frequently used arc lights to create enough light for large screens. If film jammed near the light, the heat of the lamp would ignite it. Projectionists had a large bucket of sand near each projector in case the film jammed.

      So I guess this morning’s tune should be Celluloid Heroes, by The Kinks (1972). I had this live version when I was a kid, from their 1981 double LP, titled One for the Road:

      [the song really begins at about the 1:50 mark]

      Everybody’s a dreamer and everybody’s a star,
      And everybody’s in movies, it doesn’t matter who you are.
      There are stars in every city,
      In every house and on every street,
      And if you walk down Hollywood Boulevard
      Their names are written in concrete

      Don’t tread on Greta Garbo as you walk down the Boulevard,
      She looks so weak and fragile that’s why she tried to be so hard
      But they turned her into a princess
      And they sat her on a throne,
      But she turned her back on stardom,
      Because she wanted to be alone.

      You can see all the stars as you walk down Hollywood Boulevard,
      Some that you recognize, some that you’ve hardly even heard of,
      People who worked and suffered and struggled for fame,
      Some who succeeded and some who suffered in vain.

      Rudolph Valentino, looks very much alive,
      And he looks up ladies’ dresses as they sadly pass him by.
      Avoid stepping on Bela Lugosi
      Because he’s liable to turn and bite,
      But stand close by Bette Davis
      Because hers was such a lonely life.

      Well you can see all the stars as you walk down Hollywood Boulevard,
      Some that you recognize, some that you’ve hardly even heard of,
      People who worked and suffered and struggled for fame,
      Some who succeeded and some who suffered in vain.

      Everybody’s a dreamer and everybody’s a star
      And everybody’s in show biz, doesn’t matter who you are.

      But those who are successful,
      Be always on your guard,
      You see, success walks hand in hand with failure
      Down the Hollywood Boulevard.

      Well you can see all the stars as you walk down Hollywood Boulevard,
      Some that you recognize, some that you’ve hardly even heard of,
      People who worked, suffered and struggled for fame,
      Some who succeeded and some who suffered in vain.

      I wish my life was a non-stop Hollywood movie show,
      A fantasy world of celluloid villains and heroes,
      Because celluloid heroes never feel any pain
      And celluloid heroes never really die…

        1. I like it too. I saw on youtube there were at least several different live takes, along with the studio version, but this version is the one I know best.

          I hadn’t thought of it or heard it in a long time, so it was like seeing an old friend again.

          Memories of my first real stereo receiver (Kenwood KR-720), Sansui floor standing 3-way speakers and Technics direct-drive turntable — all bought with paper route money — jamming out to this song (and lots of others) in the dark, standing or sitting in the ‘sweet spot’ in relation to the speakers, to get the 3D stereo image 😁

    2. Two references are also found in Genesis “Carpet Crawlers” — https://www.youtube.com/watch?v=2yUN6CsuVPw .

      As previously mentioned, fire departments made sure that towns knew about celluloid film. And note the proximity of “a salamander scurries into flame to be destroyed” and “imaginary creatures are trapped in birth on celluloid.” Flame and film stock were a BFD before “safety film”

      And, BTW, projected movie prints on celluloid were sharper and more distinct than those on safety film — they went light, film, print, lens, air, screen……while safety film went light, print, film, lens, air, screen. Safety film always blurred the images by running them through the film stock before sending them to the screen.

    3. My uncle was one of those projector operators…
      When I was like 5-6 years old, he took me with him to work.
      I remember the room, up high in the building, Thick walls, and even the bucket of sand.
      Thanks for bringing back that Great Memory 🙂

  2. About 3 months ago I posted my provocative claim regarding the calendar on the Q Tree. The responses were much appreciated, although I elected not to respond to all the comments. I have posted a couple of responses recently and will finish that in the next week, most likely. Unfortunately NF is no longer posting here, but I will respond to her nevertheless.

    This is the follow up that I alluded to. It contains more provocative claims, so thought I’d post it here at the U-Tree. Not sure if Trigger Warnings are needed here 

    The world as we experience it is made up of dualities. Love / Hate; Good/Evil; Heaven / Earth (Hell?) Cold / Hot; Ice /Fire; Q-Tree / U-Tree. Mankind mastered Fire a long time ago (this is Satan’s domain, after all), but we only have very limited mastery of ice, by deploying fire (fossil fuel resources).

    Thermal engine efficiency can be improved by either raising the temperature of the heat source, or lowering the temperature of the heat sink (or both). It is only by lowering the second that we have a chance to approach 100% (check formula for Carnot efficiency). Traditionally we have used the ambient environment as our sink, which has restrained our ability to increase power plant efficiency.

    I have been shown a way to thermally invert a mountain – to bring Mount Everest conditions (or colder) down to ground level. We will be able to make it snow in the Sahara in summer, using renewable energy that runs on Daughn’s schedule, that is, 24/7/365. In fact, we should be able to make it snow dry ice in the Sahara, as if we were on Mars …. The solution to “carbon pollution” is ……… MOAR carbon!!! God has a sense of humour, after all.

    This all started in 1993 when I was given a set of rare earth magnets and I figured out within a couple of weeks how to make a Curie point heat engine. I was very excited at the time – all I needed was some Gadolinium (Gd). Which I was unable to source …

    Gadolinium has a Curie point of 20C, which means that it is ferromagnetic below that temp, and paramagnetic above. This obviously changes the strength of the induced magnetic field in the Gd, which allows for some cool manipulation of magnets. You can approach 2 powerful magnets with N poles facing with a thin piece of cold Gd between them, with almost no net repulsion force. Warm up the Gd to above 20C, and the magnets exert nearly full repulsive force and have the potential to do work.

    10 Years later, the internet existed, we had sold our farm and I remembered the project, having nothing better to do. I also fell down a deep rabbit hole spiritually, which I am still in. The secular explanation is that the filter between my left and right brain hemispheres was greatly reduced, and “stuff” started flowing in. I discovered somewhat late that this was the Holy Spirit …

    I bought some Gd in Vancouver, sourced from Mongolia and proved that the engine works. Small problem – it is a heat engine, and energy flows from hot to cold. For this engine to have any practical use, I needed access to a heat sink of – 50C at least, the colder the better. We were looking at countries to migrate to and were flying around a fair bit – I noticed that the outdoor air temps at cruising altitude was around -50C. The problem was, cruising altitude is 30 000 ft plus. Mount Everest high.

    Well, that stumped me good, for obvious reasons. But the rabbit hole was long and winding, with no end in sight. Fully formed ideas were occasionally being dumped into my conscious awareness that I could not account for.

    We migrated to Aus, and I could not get work as an engineer – had been farming too long. After a business failure during the Big Crash, I retrained as a Refrigeration Mechanic. I developed and registered a patent in Aus pertaining to boosting the performance of an Air Con in heating mode. We were living in Tasmania, so A/C’s run primarily in heating / reverse cycle mode. Turns out this patent held the key to the problem of delivering Mount Everest temperatures to ground level, but time had to pass … Anyway, after that laborious preamble, herewith the nitty gritty.

    The basic physics required. Gas laws and gravity acting on the atmosphere. Warm air rises and cools with altitude, due to lowering air pressure – convection. This reduction in air temp with altitude is termed the lapse rate. This is the quick / dirty description, I’m sure Steve would do it better. This is part of the answer as it explains how we end up with cold conditions on Everest. How do you harvest that?

    Well, water is the answer, properly deployed (maybe with some spirits added, just in case). Think about the ocean and the atmosphere. The deep ocean is very cold, because cold water sinks (more dense). The warm water sits at the surface (rises, less dense). At the ocean / atmosphere interface, they are pretty much at the same temp. Then, as you go up though the atmosphere, the air gets colder. So, cold down deep, warmer as you rise to the ocean surface to a maximum, then colder as you rise through the air.

    So build a 10 km high structure and use the thermosiphon effect to dump ground level heat at the top and bring sub-zero water / alcohol (or glycol) down to the ground. Yeah …. No. Who’s going to listen past the 10 km structure, right? God had issues with the Tower of Babel, after all.

    Turns out, there is a hack you can do. Want to go 10 km’s up? Build ten 1 km towers. Huh? Each 1 is still only sitting 1 km off the ground, not very cold up there … That is where the hack comes in.

    So here is the seed for the Tree of Life. I call it a Joshua tree …

    Sorry for the shocking claim – but this is the U Tree, where shocking things are supposed to be said

    So, ten 1 km towers (carbon fibre tubes ala Boeing Dreamliner fuselages) lined up in a row. Actually, a circle would be better, but I digress. Set up your first hydronic circuit up as follows. Heat exchanger externally placed at the top, coupled to heat exchanger internally placed at the bottom. The bottom heat exchanger is a double decker, with the second exchanger linked to another double decker internally placed about 2/3’s of the way up. The first deck of this exchanger is hydraulically linked to a single decker at the base of the second tower, internally positioned …

    The second tower has a double decker about 2/3’s (call it T2), second decker linked to its base heat exchanger (B2) and the first decker (of T2) linked to the base of the third tower, B3 , and so on .

    Sorry for lack of a diagram. The basic picture is that the heat exchanger near the top of each tower is hydraulically linked to the base of the next tower, transferring the cold from the top of each tower to base of the next tower. Problem is that cold at the bottom of a tower will not cause air to rise. That is the purpose of the exchangers places 2/3’s of the way up. One deck of the exchanger is rejecting heat in order to “harvest” the cold, the second deck is a heat booster to assist in lifting this air up the tube, drawing the cold air up the tube, expanding and cooling further as it rises. This serial arrangement continues until the desired effect is achieved.

    Now, there is some tube length” loss” due to the need to create a buoyancy lifting effect in the tube. There are some design modes here to mitigate this, which I won’t go in to here. It involves heat boost management, branching of the main tube (these 2 upwardly directed branches will resemble a Joshua tree) or a less expensive main tube “cap” for the lifting section above the top exchanger, amongst others.

    The hydraulic circuits all circulate b.m.o. thermosiphon, the air rises up the tubes due to heat added near the top. The system runs day and night, needing only gravity to drive the lapse rate and the thermosiphon. The sun needs to come up the next morning so that life can go on. This has been briefly vetted by a former professor of Fluid Mechanics – agrees that it works as laid out. He wonders about the cost but balances that against the expenditure on “unreliables”.

    Each tower operates colder than the preceding one, as if they were vertically stacked. This system would work best with the tallest possible towers, requiring less series connections. The Burj Khalifa is a 830m high steel structure. Carbon fibre construction is very light, strong and flexible. Think pole vaulting poles, what they can “do”. So, 3 km tubes? Kilimanjaro, sitting in the tropical zone with a permanent snow cap is just under 5000m (peak at 5 900m altitude) high from its base. So 2 x 3 km tubes, and we are above the snow line, thermally speaking.

      Lots of hurdles here obviously, but the PLANET has to be SAVED so Greta can stop crying. The biggest problem, by a huge margin, is that California has banned straws, and this proposal requires GIANT straws, made of …..GASP ….. CARBON. One could call it the carbon solution to carbon pollution.

      Donald Trump plays 4D chess – God plays Infinity D Chess. This Tree will work 24/7/365. Once you have large scale Fire and Ice, the “fruit” that you can “grow” starts to multiply. Water is condensed out of the air, or fresh water “frozen” out of the ocean. Water condensed out at a controlled height, delivered into a pipe – hydro power. Picture large scale hot houses being irrigated and the moist air extracted up a tower, all the water returned back to ground after driving a turbine – simple old conservative tech. A CO2 working fluid power station. Ambient heat boiler at ground level, -80C condenser at height, CO2 liquid delivered into a pipe at height, ground based turbine. The ambient Boiler is actually a surface cooler – so cold air will be a “waste” product. Mass cooling for superconducting . Snow in the desert for some R&R. One could expand this list quite easily.

      Remember that God wants his prodigal children to return, and the loyal older son was a bit grumpy? This is how that is going to play out. So get your grumpiness out on me, and let me have it. This is what the U Tree is for ….

      Donald Trump wrote the Art of the Deal. God wrote the Bible. Looks like God has packaged a deal here to merge “left” and “right”, the prodigal son with the loyal son. If you think about it, God is offering the “left” all they have been asking for, except He is part of the package. The “right” want God, but not all the stuff that the left have been clamouring for. This is a compromise deal for the “left” and the “right” – but God wins bigly …

      I alluded to the Key of David before – the keys to heaven entrusted to Peter. Turns out that the Key of David is symbolised in the Star of David. The two triangles interlocking apparently symbolise the merging of heaven and earth. One pyramid reaching up, one coming down. So inverting a mountain, thermally speaking, matches the motif.

      The Egyptians invested heavily in pyramid tombs – serving no earthly benefit, but it bound them to their gods. They lasted for several thousand years. God did not bless them by coming down from heaven. That blessing is about to be bestowed on humanity – we just have to plant the seed. The fruits will be everlasting …
