Elilka Sieyes: Evening (decided I’m so lagged today that coming to the salon will probably push me into negative lag 🙂 )
Viv Trafalgar: lol.
Viv Trafalgar: funnneeeee
Elfod Nemeth: well, it is Sunday after all
Doctor Obolensky: Isn’t negative lag good?
Serafina Puchkina: Rats. Sorry, Dr Watson. Welcome to you!
Doctor Obolensky: Or do you mean seconds per frame instead of frames per second?
Breezy Carver: hello dear Sea .. wavess to Jed and Canolli .. and dr Holmes Jasper .. umm Kat .. wavess to Elf .. and Mr Meryman (( one man ))
Viv Trafalgar: Hello Watson (does whatever Sera says)
Jedburgh30 Dagger: i thought that if you put lag and Anitlag in the same space they’d explode
Breezy Carver: Sera * woopsy
Viv Trafalgar: come on in and have a seat folks –
Elfod Nemeth: hello Breezy 🙂

Viv Trafalgar: we would appreciate it
Greg Merryman makes a note about note takers
Viv Trafalgar: otherwise I have to return the tea
Viv Trafalgar: ::makes a note about Mr Merryman Making Notes::

Jasper Kiergarten: do you need a chair Miss Strathearn?
Beq Janus smiles
Bookworm Hienrichs: Miss Sands, I must express jealousy of your title. grin
Breezy Carver: wacves to Miss Sands (9 love love your hair ))
Penelope Strathearn: I have one, thanks. I’m sending an lm to a friend
Viv Trafalgar: Welcome Mr. Worbridge
Serafina Puchkina: Mr Worbridge, welcome
Breezy Carver: Beq Beq ~~
Alyx Sands: Why thank you!
Jasper Kiergarten: you’re welcome
Breezy Carver: ☆smiles ☆ love it !!
Osric Worbridge: Thank you
Viv Trafalgar: we’ll get started in just a few minutes –
Viv Trafalgar: WB Beq!
Beq Janus waves
Serafina Puchkina: Speakers, if you want to have a seat on the stage. ..
Breezy Carver: waves to beq jumping
Serafina Puchkina: And Helio has the pole so far! Woot! (Indy 500)
Elfod Nemeth: aargh! my feet!
Bookworm Hienrichs chuckles.
Viv Trafalgar: oh no Elf you’re too tall for those!
Elfod Nemeth: grins
Jasper Kiergarten: anyone wanting a chair, please let me know
Elfod Nemeth: I’m too tall for everything
Greg Merryman: you can lay down
Viv Trafalgar: Hello Saffia – Welcome!
Breezy Carver: Greg you cant lay dow
Greg Merryman: can*
Byron Wexhome: May I have a chair?
Breezy Carver: down why working
Alyx Sands: I’m usually too SHORT for everything….
Elfod Nemeth: lol
Breezy Carver: wavess to Saffia with a big smile
Beq Janus notes that everyone is sitting further back than usual, clearly the two speakers engine building escapades have taught many a lesson already
Saffia Widdershins waves back as things and people slowly rezz
Viv Trafalgar: chuckles
Serafina Puchkina: Welcome, welcome
Elilka Sieyes ponders protective goggles.
Kat Montpark waddles forward with her chair stuck to her bum.
Viv Trafalgar: as long as there’s room for the stragglers
Penelope Strathearn: I’m just sitting this far forward due to lag lurch. g
Jedburgh30 Dagger: I’m Baptist
Alyx Sands hobbles along too
Serafina Puchkina clears her throat to begin
Viv Trafalgar: we really should race these things sometime
Kat Montpark: Hee!
Saffia Widdershins wonders how one gets a chair …
Serafina Puchkina: Welcome, fine ladies, elegant gents, and intelligent urchins. Miss Viv Trafalgar and I welcome you all to the eighth Aether Salon: Engines!
Viv Trafalgar: Coming Saffia
Penelope Strathearn: giggles at Jed, and decides to offer her some fried chicken after the Salon
Serafina Puchkina: The number 8 in Chinese culture carries great significance. It is an auspicious number, because the Mandarin word for “8” is similar to the word for “wealth” or “prosper.” “88” sounds similar to “double joy.”
Saffia Widdershins beams
Saffia Widdershins: Thank you!
Serafina Puchkina: We are positive that today’s salon will bring great wealth and prosperity to you all — just see Bob afterwards. (::notes Bob making himself scarce::)
Jasper Kiergarten: you’re welcome
Elfod Nemeth: wonders about the crazy 88….
Serafina Puchkina: We are so humbled by the support we receive from everyone in the community, and we thank you all. Many fine people have contributed to today’s salon; we are grateful to Miss Ceejay Writer, Miss Breezy Carver, Miss Redgrrl Llewellyn, Miss Canolli Capalini of Capalini Fine Furnishings for the chairs, and Albus Weka and Jasper Kiergarten who helped Viv create today’s craft – make-your-own toolbelts!
Viv Trafalgar: lol
Serafina Puchkina: Miss Viv, my co-host, is incredibly talented, compassionate, intelligent, and funny. I treasure her close friendship and support.
Kat Montpark: Hooray!
Jedburgh30 Dagger: yay
Canolli Capalini applauds
Viv Trafalgar: looks at tips of boots
Serafina Puchkina: Hold your questions until the end, and as a courtesy to all, please turn off everything that encourages lag – (sorry sir, that internal combustion engine must go for a bit), all HUDs, scripts, AOs and so on. Please, no weapons, bombs, or running with sharp objects.
Breezy Carver: YAY to you both !!
Viv Trafalgar: they’re cute boots
Alyx Sands cheers
Breezy Carver: very cute boots !
Serafina Puchkina: Mark your calendars for upcoming salons: Fae! in June, a brief hiatus, then Airships! in September, and Haberdashery! in October.
Serafina Puchkina: Check out aethersalon.blogspot.com for edited and unedited transcripts of this and previous salons, a list of speakers, photos, and assorted witticisms in the “Overheard at the Salon” section. If you would like to join the Aether Salon group and receive notifications of future salon events, click the lower right hand corner of the large brown sign by the entrance.

Breezy Carver: coughs
Viv Trafalgar: grins
Breezy Carver: sigh
Serafina Puchkina: After the question and answer period, today’s incredibly useful craft will be distributed.
Serafina Puchkina: Before we ask you to start your engines… Miss Viv has a few words to say about today’s speakers –
Viv Trafalgar: Welcome everyone – and thanks to my co-host the wonderful Miss Serafina Puchkina
Viv Trafalgar: if you can’t hear me, you are sitting too far back 🙂
Jedburgh30 Dagger: huh?
Viv Trafalgar: Our two speakers today are (puts Jed on the list AGAIN)
Viv Trafalgar: Elfod Nemeth and Greg Merryman
Penelope Strathearn: If they can’t hear you, how will they know you’re talking to them? 😉
Viv Trafalgar: Elfod Nemeth is an avid builder (assembling, scripting and texturing) who accepts custom bespoke builds and sells occasional items of well-scripted goodness at his shop Steam Monks.
Viv Trafalgar: ((that’s the joke Nell :))
Viv Trafalgar: His portfolio can be found at http://knol.google.com/k/elfod-nemeth/elfod-nemeth-second-life-portfolio/
Viv Trafalgar: Elfod’s most eye-catching builds in New Babbage are Tiny Tim and Dagon’s Pier. Both are resources for the use of any visitors to or residents of Babbage; however, Tiny Tim is also Elfod’s home.
Viv Trafalgar: The Pier is a Victorian-style pier modelled after the famous Iron Bridge. It features entertainments (with more planned) and leads, via a pleasant walk, to the giant robot Tiny Tim.
Viv Trafalgar: Tiny Tim is a 160m tall, hollow robot. Explorers who traverse its exterior and venture inside may discover a mushroom brewery and dance floor,
Viv Trafalgar: a couples lounge chair with sea view, a Mars Expeditionary rocket, an avatar cannon,a games room, a mushroom shredder (that should not be touched!),
Viv Trafalgar: a second, wet dance floor, a couples tree and many places to high-dive from and swim.
Viv Trafalgar: Tiny Tin and Dagon’s Pier can be found at http://slurl.com/secondlife/Vernian%20Sea/219/39/117
Viv Trafalgar: Greg Merryman is a renowned mechanologist who has forgotten more about engines than many of us will learn in a lifetime.
Viv Trafalgar: Since arriving in Babbage, Mr. Merryman has created a number of builds that have caught the eye of the discerning traveller –
Viv Trafalgar: from the Soap Factory of yore and the Fire Station (now the Ladies’ Fire Brigade House), to the stunning steel mill in Iron Bay.
Viv Trafalgar: Greg is however very humble, saying only, “I am a student of the art of mechanics I fix things and build things.”
Viv Trafalgar: His most recent creations include a new submarine and the tri-tanium airship, as well as scripting for the Iron Bay fleet.
Viv Trafalgar: As for engines, they are a passion in this life and in RL.
Viv Trafalgar: Iron Bay can be found in Babbage New Babbage, http://slurl.com/secondlife/new%20babbage/101/52/102/.
Viv Trafalgar: Ladies and gentlemen, please put your hands together for Elfod Nemeth and Greg Merryman.
Jedburgh30 Dagger: claps
Canolli Capalini applauds
Serafina Puchkina applauds
Penelope Strathearn claps
Saffia Widdershins applauds
Breezy Carver: claps claps .. for both and for Viv .. yay
Greg Merryman blushes
Alyx Sands applauds
Elfod Nemeth: Good Evening all I’m going to give you a brief talk about Sterling Engines, followed by a more thorough talk covering many types of engines from Mr Merryman.
Elfod Nemeth: In order to put the Sterling engine into historical context, lets look at when engines where perfected during the 19th century. When I say perfected I mean developed into a usable state where they could be put to practical use.
Elfod Nemeth: As we can see, Sterling engines where made practical in the early 19th century. The engines we see here all had their own quirks:
Elfod Nemeth: Steam engines were high pressure with steam as the fluid motivator (what pushes the piston), were dangerous due to poor understanding of metal fatigue, high power density generation and high maintenance. They were typically used in large applications – factories, ships, trains.
Elfod Nemeth: Sterling Engines have low power density, run on ambient heat or cold source, use ordinary air as fluid motivator, extremely safe (impossible to explode), near silent operation and are very low maintenance.
Elfod Nemeth: Internal Combustion engines have higher density of power than ever before, use volatile explosive fuel, high maintenance and can be used in mobile applications. As a result they quickly went into went into mass production and have seen over 100 years of refinement
Viv Trafalgar: No exploding engines?
Elfod Nemeth: not from sterling engines, no
Viv Trafalgar: well hmph
Elfod Nemeth: Here we can see the relative merits of these engines in terms of efficiency. It’s surprising just how efficient the sterling engine is. So why aren’t we surrounded by Sterling engines today? In the 19th century sterling engines were made from cast iron, as were steam engines, and even though they weren’t subject to the same metal fatigue as steam engines they were prone to burn out on one end due to oxidisation of the iron where the heat source was applied, creating a hole and resulting in pressure loss.
Elfod Nemeth: Here we simplest form of Sterling engine, what is more correctly termed a heat engine. A cylinder is heated at one end, then cooled at the other. This forces the air to rise, then cool, creating rising and falling air pressure within the cylinder. A piston, seen at the top here, is sucked and pushed as a result creating motive force. This is horrifically inefficient as we can see.
Elfod Nemeth: This development, still a heat engine, adds a displacer, a moving piece that shuttles back and forth within the cylinder. The displacer, loosely fitting, shunts the gas, usually aided by the fly wheel so the cooling and heating are applied faster. Amazingly this doubles the performance from 1% to an astonishing 2%! Heady stuff.
Kat Montpark laughs.
Elfod Nemeth: Here is where Robert Sterling comes in adding the innovation that made sterling engines practical. Along the side we can see a heat sponge otherwise know as a regenerator. This simple addition retains heat as the air in the cylinder passes between hot and cold states, heating and cooling the air faster, retaining heat that would otherwise be lost to the surrounding environment.
Elfod Nemeth: The model you see here (both are identical) display a form of alpha engine that doesn’t have a displacer but does have a heat sponge regenerator in the form of a metal mesh. Heat is collected from the rising geothermal water on the right, heats the air in the tube, which passes through the regenerative mesh. The hot expanding air pushes up the cylinder exposing the air to the cooler part of the cylinder, cooled by the protruding heat sink vanes. The cooled air contracts passing though the heat sink warming as it passes to be heated again from the geothermal water and the cycle starts again.
Elfod Nemeth: So what happened to Sterling engines?
Viv Trafalgar: Seriously – they seem like they’d be completely useful
Viv Trafalgar: and clean
Elfod Nemeth: Because of poor materials (basic cast iron) Sterling engines had a high failure rate, the iron simply oxidised after prolonged exposure to a heat source and perforated. Despite this tens of thousands of Stirling engines were used to power water pumps, run small machines, and turn fans, from the time of their invention up until about 1915.
Elfod Nemeth: As electricity became more widely available in the early 1900s, and as gasoline became readily available as a fuel for automobiles, electric motors and gasoline engines began to replace Stirling engines which never got the chance to fulfil their full potential.
Elfod Nemeth: Today Sterling Engines are seeing something of a revival, being used where there are abundant free sources of energy, such as geothermal vents, concentrated focused sunlight and even the excess heat from other engines. Elfod Nemeth: I leave you with a rather poor picture from Robert Sterling’s 1816 patent application of the air engine design which later came to be known as the Stirling Engine. And words of the man himself:
Elfod Nemeth: “…These imperfections have been in a great measure removed by time and especially by the genius of the distinguished Bessemer. If Bessemer iron or steel had been known thirty five or forty years ago there is a scarce doubt that the air engine would have been a great success … It remains for some skilled and ambitious mechanist in a future age to repeat it under more favourable circumstances and with complete success…” (written in the year 1876 by Dr. Robert Sterling [1790-1878])
Serafina Puchkina whispers: amazing
Viv Trafalgar: I would love to see a few of those slides again Elfod –
Canolli Capalini applauds.. quietly.
Elfod Nemeth: now?
Beq Janus: Can we get them put on the Ning?
Viv Trafalgar: Perhaps, or if you’ll put them online somewhere/
Viv Trafalgar: yes, exactly!
Elfod Nemeth: I can certainly do that
Viv Trafalgar: We can take a couple of questions for Elfod –
Viv Trafalgar: while Mr. Merryman gets set up
Viv Trafalgar: ((the grid is a little wonky today – we are so glad so many of you were able to make it, despite the … wonk))
Greg Merryman: no questions for Elfod?
Alyx Sands: ((wonky is a nice way to put it))
Viv Trafalgar: I have a couple –
Viv Trafalgar: but others should go
Elfod Nemeth: grins
Jedburgh30 Dagger: ((Greg looks 8bit))
Viv Trafalgar: lol
Viv Trafalgar: we can keep going and run questions at the end. I’ll save mine on my List I have here…
Greg Merryman: ok
Viv Trafalgar: Thank you Elfod!
Greg Merryman: Hi, first I’d like to thank Viv and Sera for inviting me to speak at the very prestigious Aether Salon and to thank all of you for attending and I’d like to thank Mr Elfod Nemeth for his enlightening presentation of the Sterling engine and hopefully adding his wit and charisma to what would otherwise be my very dry and boring presentation.
Viv Trafalgar: lol
Greg Merryman: Steam engines and stirling engines are both examples of external combustion engines; that is: engines whose heat source is on the outside of the engine rather than on the inside like the German gasoline engine created by Mr Otto that you may have seen about.
Greg Merryman: The first know steam engine (the aeolipile) was invented in the first century AD by Hero of Alexandria but it was simply a novelty. I created an aeolipile for your viewing pleasure (to my left near the beverage dispenser) and feel free to get one from the box next to it (buy for 0L).
Viv Trafalgar: Yay! Toyz!
Alyx Sands: Oooh, decorative pieces for my house!
Viv Trafalgar: ((I knew I felt something hot over here))
Greg Merryman: I was standing over there earlier 🙂
Viv Trafalgar: ::puts Greg on the List::
Greg Merryman: Steam technology lay dormant for nearly 1,500 years after Hero created his toy.
Autopilotpatty Poppy takes notes
Greg Merryman: It seems hard to believe something as important as steam power could have been lost for so long but it appears to the case.
Greg Merryman: Steam engines weren’t mentioned again in history until the prolific Muslim inventor Taqi al-Din Muhammad ibn Ma’ruf al-Shami al-Asadi (and no, I won’t go voice and pronounce that for you “) describes a steam engine and steam turbine in a book he had written named “The Sublime Methods of Spiritual Machines”.
Viv Trafalgar: people were too busy killing each other?
Kat Montpark tsks.
Greg Merryman: I’m not really sure what happened
Alyx Sands is a linguist and COULD pronounce it…
Jim sneaks in quietly.
Greg Merryman makes a note of that fact
Serafina Puchkina loves the name of that book
Greg Merryman: “The Sublime Methods of Spiritual Machines” which is just the coolest name for a book, ever.
Greg Merryman: thanks for that Sera 🙂
Alyx Sands goes to get a copy for her library
Kat Montpark: I would have thought it was a book about meditation, on that title.
Greg Merryman: Other inventors and tinkerers mention steam turbines and engines in their writings but it wasn’t until an English military engineer named Thomas Savery in 1698 invented one he called the Miner’s Friend, and even that wasn’t really what we’d call an engine. It was a pump used to pump water out of mines and it did not even have a flywheel or many moving parts.
Greg Merryman: We should stop and talk about the theory behind the early steam engines which applies to the stirling too I guess.
Greg Merryman: For the most part, when matter is heated it expands and when cooled it contracts. (yes, your pipes burst when they freeze but that’s an odd case)
Elfod Nemeth: unique too
Greg Merryman: this is also how an internal combustion engine works… gasoline explodes in the cylinder and the expanding gasses are what push the pistons
Greg Merryman: When we think of a steam engine we imagine very high pressure, hot, expanding steam pushing on engine cylinders to do work but many of the early steam engines did not work that way.
Viv Trafalgar: Grins
Greg Merryman: Most early steam engines only used the hot steam to return the cylinders back to where they started.
Greg Merryman: It was the idea that things contract when they are cooled that did the actual heavy lifting.
Greg Merryman: Engines that capitalize on the fact that when you cool off matter is contracts are known as “atmospheric engines”, due to the fact that the atmosphere is doing the pushing into a much lower pressure vessel.
Greg Merryman: it*
Greg Merryman: Basically what Mr Savery built was a large coffee percolator. All he did was shoot steam into a pipe that was down in some water at the bottom of a mine….
Greg Merryman: Then he shutoff the steam and waited for the lake to cool the pipe and condense the steam into the pipe back into water thereby creating a vacuum.
Viv Trafalgar: I would have SO passed my materials that shape civilization course if I’d come to salon first.
Alyx Sands: /gets a sudden craving for fresh coffee
Greg Merryman: The atmosphere pushed the mine water into the very empty pipe, them he closed the valve at the bottom of the pipe.
Viv Trafalgar: lol @ Alyx
Autopilotpatty Poppy smells the freshly perked coffee
Greg Merryman: Then he’d let steam back into the water filled pipe until it overflowed the water and then did it all over again, of course the fairly high pressure steam blasting into the relatively cold water in the pipe meant a lot of its energy was wasted needlessly heating up the water and the steam had to be fairly high pressure which is why they had so much trouble with the builders exploding..
Greg Merryman: boilers* exploding
Kat Montpark laughs.
Greg Merryman: Word does not fix everything, it seems
Elfod Nemeth: beans?
Viv Trafalgar: hehe
Greg Merryman: It was terribly inefficient but it was somewhat better than horses or donkeys pulling a rope that had buckets tied to it.
Jedburgh30 Dagger: mmmm
Serafina Puchkina appreciates that both speakers are defining terms for non techies such as herself
Greg Merryman: It could only lift a column of water about 40 ft (12M) so deep mines had to have a series of these pumps one above the other.
Alyx Sands is still dreaming of coffee…
Greg Merryman: Oh and the boilers that generated the steam blew up fairly often
Greg Merryman: But he did do one thing incredibly right… he got a patent that covered the use of steam to make things move….and a law was passed that extended his patent for a total of 35 years.
Greg Merryman: Next we come to Thomas Newcomen
Elfod Nemeth: as if mines in those days weren’t already scary enough
Kat Montpark: Oooo, lucky him!
Viv Trafalgar: seriously.
Greg Merryman: In 1712 or so, Thomas Newcomen, another Englishman improved upon Savery’s design considerably. Mr Newcomen separated the engine from the water that was being pumped and figured out that if injected a small amount of cold water into the cylinder it would rapidly condense the steam back into water and create a powerful vacuum. This was a huge step forward and was much much more efficient than Savery’s engine.
Viv Trafalgar: Greg did you make these illustrations?
Viv Trafalgar: ooo.ooooo
Greg Merryman: naw… borrowed them
Viv Trafalgar: they’re gorgeous
Gizmo Theas: Nice animation
Greg Merryman: lol still rezzing for me
Greg Merryman: He used steam (the pink in the animation) to lift the cylinder back up, then he shot a little bit of cold water into the cylinder to condense the steam and create a partial vacuum, which sucked the engine-side of the beam downwards and lifted the plunger in the pump deep in the mine.
Alyx Sands polishes her glasses, but it still looks fuzzy
Greg Merryman: that shot of water was the magic sauce
Viv Trafalgar: lol
Greg Merryman: but there was a problem… Savery had locked up the steam pumping water out of the mine business with a patent
Greg Merryman: but even that he installed over 100 steam engines all over Europe before his death.
Greg Merryman: A number of attempts were made to use the Newcomen steam engine to drive various machines rather than pumps, but they all failed due to the intermittent pulsing motion of the engine. The Newcomen engine was used pretty much as is for 50 years.
Greg Merryman: this pic is one of the few surviving Newcomen engines
gstone Turas: Viv you are a dear, but I’ve been sitting entirely too much – thank you though.
Viv Trafalgar: 🙂
Greg Merryman: James Watt, a Scotsman, came up with the idea to condense the steam in a separate vessel from the main engine cylinder. Newcomen injected water into the thick walled cast iron cylinder to condense the steam but it also cooled the engine off quite a bit. So the next injection of steam into the engine to start the next cycle had to re-heat the somewhat cooled off engine which wasted a lot of the energy that the steam contained.
Greg Merryman: After many false starts, Watt teamed up with a guy named Matthew Boulton who owned a foundry.
Greg Merryman: They installed their first engine in 1776 which was still basically a pump. Boulton urged Watt to turn the reciprocating pump into a rotational engine. A man by the name of James Pickard held the patent for the crank (it seems the patent office was just as screwed up back then as today), one of Watt’s employees invented the Sun and planet gear to get around the patent on the crank .
Greg Merryman: they had to turn the recipircating motion into rroational motion using this… cause some guy patented the freakin crank of all things
Viv Trafalgar: the patent office? Screwy?
Viv Trafalgar: nah
Alyx Sands: Cranky!
Kat Montpark laughs again!
Canolli Capalini: cracks up
Greg Merryman: I didn’t know it was screwed up for that long
Viv Trafalgar: patent trolls of the 19th century!
Greg Merryman: lol at Alyx
Greg Merryman: Watt went on to create a double acting engine that used steam on both sides of the piston to move it back and forth. He was the first to add a centrifugal governor to automatically regulate the speed of the steam engine
Greg Merryman: now that”s finally my idea of a steam engine
Greg Merryman: Watt went on to create a double acting engine that used steam on both sides of the piston to move it back and forth. He Watt was adamant about using only low pressure steam to power his steam engines. He felt (and rightfully so at the time) that high pressure steam was just too dangerous. Iron was not a very good material to use for boilers, cylinders etc. due to its brittleness…. Boilers made of iron would fail spectacularly rather than just develop a leak when something went wrong.
Viv Trafalgar: that’s gorgeous.
Saffia Widdershins: Circumlocution Office in Little Dorrit … that’s all about patents being screwed
Kat Montpark: OOo, can’t yet imagine one o’ those in City Hall?
Viv Trafalgar: haha!! Excellent connection Ms Widdershins!
Alyx Sands silently curses at circumlocutions
Greg Merryman: that’s blur is an example of a double acting piston
Greg Merryman: steam pushes it both ways
Greg Merryman: double action was a huge improvement
Greg Merryman: I built a steam engine is SL awhile back…. this was what I based it on
Greg Merryman: I don’t think it would operate here with all the lag so I won’t get it out
Kat Montpark: Say what ye will about crazy patents, it makes for a beautiful-looking machine.
Viv Trafalgar: there’s one at the Benoir’s place in Wheatstone!
Viv Trafalgar: it’s awesome
Serafina Puchkina: I agree Kat
Greg Merryman: by this time the patent for the crank had expired
Greg Merryman: Methods of smelting the iron improved and with the addition of coke (a by product of crude oil refining) into the iron as combustible, iron makers in the middle 1800s were actually making a crude from of steel which greatly improved the boilers.
Alyx Sands resists the urge to yell “crank shafted”!
Greg Merryman: my steel mill in the Iron Bay uses coke mixed in with the ore in the furnace
Viv Trafalgar: lol
Greg Merryman: they did not get a good mix of steel this way tho… some of the material was iron and some was steel
Greg Merryman: Someone along the way got the brilliant idea to make a plug out of lead and put into the boiler. If the boiler ran out of water or built up too much pressure the lead plug would melt and blow relieving pressure on the boiler and directing the steam to hopefully a safe area rather than into one’s face. This is not unlike the re-useable pop off valve on today’s water heaters.
Serafina Puchkina is impressed: “Pretty clever.”
Greg Merryman: Low pressure steam (1 or 2 PSI) where much safer than higher pressure engines but they had to be quite large and heavy in order to get any work out of the low temp low pressure steam. A true Watt engine was far too large and heavy to be used in vehicles except for a steam locomotive which he patented in 1784.
Viv Trafalgar notes some friends of the mayor in the audience and wonders if this would look good in city hall
Greg Merryman: you can see in this diagram they’re starting to get more complicated
Viv Trafalgar: ooo schematic pr0n
Greg Merryman: Watt retired in 1800 the same year his original separate condenser patent ran out and many, many companies and inventors all over the world began to make steam engines. These next slides are photos of some of the post-watt engines.
Viv Trafalgar: ::blushes::
Alyx Sands giggles inappropriately and blushes too
Greg Merryman: Watt’s steam engine ushered in the Industrial revolution in Europe. No longer did factories have to built alongside rivers or rely on the intermittent wind to operate. Factories would generally have one large Watt engine that drove a series of pulleys that powered many devices in the factory. Grinders, saws lathes, sewing machines were just some of the tools that would get their power from an overhead pulley/belt that was powered by that one big steam engine.
Autopilotpatty Poppy looks around innocently
Viv Trafalgar: grins
Jedburgh30 Dagger: gearhead pr0n
Greg Merryman: As the 19th century progressed many inventors continued to improve upon the steam engine. The created multiple cylinder engines that extracted work from the waste steam from the preceding cylinder to further increase efficiency. Europe was afraid of high pressure stream engines due to the problems they had seen with them in the past but the US had no experience with exploding boilers etc so Americans quickly surpassed the gun-shy Europeans in the creation of high pressure steam engines.
beth India: it was incredibly dangerous in the large factories though, many children and adult were killed by these machines
Greg Merryman: yes…. limbs were lost too
Viv Trafalgar: aye Beth, completely right
Autopilotpatty Poppy shudders
Greg Merryman: no belt guards or OSHA back in those days
Canolli Capalini: because that’s where children and women belong, on the factory floors.
Jimmy Branagh: Ay!
Jimmy Branagh: Wotch it!
Alyx Sands: OI!
Viv Trafalgar whispers to Canoli… ‘don’t make the urchins mad… they’ve been holding meetings….’
Greg Merryman: this is a very efficient engine… it uses waste steam from the first cylinder to power the second and so on
Greg Merryman: this type of engine would have been used on ships for instance
Greg Merryman: very high pressure/hot hot steam
Beq Janus: erotica again
Galactic Baroque: supersaturated
Canolli Capalini: all that pumping.. and pushing and pulling.
Beq Janus moans
Canolli Capalini fans herself.
Greg Merryman: lol
Kat Montpark snickers.
Alyx Sands: /moans too
Viv Trafalgar: there’s the babbage I know and love.
Greg Merryman blushes yet again
Elfod Nemeth: chuckles
Boh Benoir: blushes.
beth India winks at Beq
Galactic Baroque looks at the ball governor and gasps
Boh Benoir: Another steamy Salon…
Canolli Capalini: chuckles
Greg Merryman: building a steam engine in SL is easy…. scripting it is hard
Kat Montpark: In every sense o’ th’ word. winks
Viv Trafalgar: aye –
Jasper Kiergarten: that’s the truth
Viv Trafalgar: what’s the hardest part?
Boh Benoir: grins as Jasper.
Greg Merryman: my most successful attempt used llSetAlpha to turn on and off a series of 8 axles, 8 pushrods and 8 pistons
Viv Trafalgar: um. and by that I mean, what is the most DIFFICULT part of the task?
Jedburgh30 Dagger: heh
Beq Janus giggles
Alyx Sands takes linguistic notes of inappropriate gearhead pr0n
Greg Merryman: the steam engine at Kandace’s lighthouse moved the prims by doing some pretty heavy math that is beyond me
Viv Trafalgar: that’s some loops you had to write, Greg.
Serafina Puchkina chuckles
Greg Merryman: yeah very loopy
beth India: recursive even
Alyx Sands scribbles frantically
Greg Merryman: and that’s concludes my presentation
Gizmo Theas: .-‘'-. APPLAUSE APPLAUSE .-'‘-.

I did notice they got larger the further down the chain that they went <b>Viv Trafalgar</b>: that's a good question <b>beth India</b>: .me quickly puts it away again <b>Jasper Kiergarten</b>: I see <b>Greg Merryman</b>: I imagine the larger size is due to the lower power steam to blanace it all out <b>Jasper Kiergarten</b>: ah <b>Jasper Kiergarten</b>: makes sense <b>Elfod Nemeth</b>: I presume they got longer because as the steam progresses it looses pressure, therefore more surface area is needed to provide sufficient motive force <b>Greg Merryman</b>: is total BS :) <b>Viv Trafalgar</b>: hah! <b>Greg Merryman</b>: oh now that' s good Elfod <b>Saffia Widdershins</b>: One of the most interesting uses of steam power I saw was in Tuscany <b>Jasper Kiergarten</b>: ah <b>Viv Trafalgar</b>: Oh? <b>Elfod Nemeth</b>: also, there is a giant aeoliophle ride on my pier in the Vernian sea, should have mentioned it earlier <b>Saffia Widdershins</b>: where they use the thermal power of hot springs in an area of Southern Tuscany <b>Viv Trafalgar</b>: what do they use it for Ms Widdershins? <b>Saffia Widdershins</b>: supplying power in the local villages <b>Saffia Widdershins</b>: the hills and roads are all crossed by these huge tubes <b>Saffia Widdershins</b>: bright yellow <b>Serafina Puchkina</b>: wow <b>Aeolus Cleanslate</b>: lots of that going on in Hawaii too - geothermal driving steam turbines producing electricity <b>Aeolus Cleanslate</b> raises his hand <b>Viv Trafalgar</b>: Yes Mr. Cleanslate? <b>Elfod Nemeth</b>: nuclear power stations use steam turbines too Greg? <b>Greg Merryman</b>: yes <b>Viv Trafalgar</b>: ahh Mr. Cleanslate and then Mr. Nemeth <b>Elfod Nemeth</b>: nods <b>Viv Trafalgar</b>: or not <b>Aeolus Cleanslate</b>: forgive me if you covered this earlier, but early steam engines seem to have alternated between vertical and horizontal boilers.
