“Water is not only the working fluid it’s also the lubricant” water may seem like a lubricant but it is absolutely not you would need to use steam oil for the lubricant
I came to comment that, water is not a lubricant at all
was just about to write the same. Jay Leno perfectly explains it in one of his many steam car videos.
Shell makes it, you can get it in big vats for full size engines or teeny bottles for steam powered models.
Exactly right. Water has no lubricating properties. Maybe a water soluble oil would do the trick
@@Kevin75668 I think it can reduce friction like hydroplaning but it doesn't prevent contact between 2 coarse matterials riding on each other
I remember as a kid staying home in the summer and binge watching this show and forensic files.
@Sean Embry very true
For me it was when it had the 8-9pm spot on Science channel on Wednesday because it was two episodes of this then switching to Discovery for that week's new Mythbusters.
I love watching this series, every episode feels smart
I had spinal fusion surgery to correct scoliosis and was out of commission for 6 months, I watched a ton
I have a feeling that Huggbee will post a video about this this week

i loved watching HIM as a child on the discovery network, such a beautiful show for children wanting to learn
Isn't that a lost gay porno?
I loved it when prototype or niche things got on the show. They obviously only have one of those motors handy...
Seriously this company needs to make a home generator, I'd love to have a generator that was low noise and could run off of just about anything.
They're very inefficient. Not by any means quiet. Take sometime to get to operating temperatures & pressure. Freezing condensers, unless you introduce glycol & that's a little special hell of it's own. They're really only applicable as waste heat generators and even then typically more trouble than they're worth. A little honda generator will do you leagues better & it can run off essentially anything as well, given a bit of tinkering.
Your best bet for a generator is an old diesel tractor with healthy batteries and glow plugs and a pto generator or a good old school generator. Something quality. Gas or propane powered is fine for small portable units. How much time do you run a backup generator..?
@@tacomas9602 Not too often thankfully!
@@Porphyrios1 Honda or Briggs, only brands I'd ever trust.

Feels like a prototype made by a couple of friends in a garage..
i dont trust any motor put together with flat head screws... that being said this is pretty cool.
Thank GOD iv been looking for how its made full episodes that aint jumping everywhere zooming in thank you for posting these!!!!!!!
Youll have to keep the water from freezing overnight if youre up north.
use anti-freeze additive to water to prevent freezing.
@@wahyutriwibowo1803 Hot antifreeze is very corrosive...
I have been in training to become a power engineer! Great subject guys.
nostalgia... this show was my pre-teen time filler. parents would put it on in the background and id end up totally entranced.
Fr lol 😂 entranced is the perfect word to describe it. You’re so smart
There are very good reasons we stopped using reciprocating steam engines. This is some cool, hobby level stuff but this isn't serious and I question their efficiency and clean burning claims.
yeah the multiple "so much cleaner/less greenhouse gases" claims are just outright lies lol.
@@toxicity4818 about the only way I can think of that it could be “cleaner” than any new internal combustion engine car is with natural gas, or maybe propane.
That’s a pretty far cry from toss whatever waste oil you want at it and produce lower emissions though.
Admittedly I’d want to look up this product before actually buying one.
@@toxicity4818 they aren’t actually, lower burn temperatures and pressures releases less NOx. This is a huge problem with jet engines as their combustion chambers run at extremely high temperatures and pressures
This engine has some serious issues to it that would be pretty quickly apparent to anyone familiar with steam power. Burning fuel at lower pressures reduces NOx emissions, but that's more of a smog gas than a greenhouse one to my knowledge.
The biggest problem I see with this thing is that it has no variable cutoff, the valves just open and close at the same part of the stroke no matter what. Such an engine will spin and develop power, but will do so horribly inefficiently, so much so that several of the key advancements in the steam age related to how steam was carefully admitted into the cylinders to take advantage of the expansion of the gas and not just it's head pressure. Corliss valve gear is the most refined that I'm aware of, and it seems much better than what's shown here. I'm also doubtful of their total condenser recovery, it's not easy to do even with huge radiators, unless this was a completely static system, and then why bother with that?
Reciprocating steam engines can have uses in industry, but I don't see these being them.
look at the condensed water. it barely moved when operating. it shows this engine doesn't have a lot of vibration. it's a well balanced engine.
Never seen a less effective way to use steam in a piston engine
It has to be one of the worst designs I've ever seen. They used a water tube boiler, great. Condensing, beautiful. Single expansion, wtf. No cutoff, wtf. No lubrication, are they high?
Oh god, I looked it up. 30% thermal efficiency and "over 1000 hours of runtime". So it won't last more than a few months and it's barely more efficient than a gas ICE at best.
@@herpnderpn2484 It seems like it's supposed to be a small, low cost steam engine.
Really what would be the use of this "machine"? They compared it to a ICE, but as a generator, it would suck, a vehicle wouldnt move a bit and even in an RC model it would eat ass with that huge open flame. And for a show piece the machining and finishing would be too crude. Is this even more than a fidget thingy that wastes steam?
@@rubiconnn I get it, but there are already cheaper and more compact forms of power. No improvement in fuel economy, and nobody knows how to work on it.
It seems DOA though. They haven't updated their website copyright since 2015 and the last activity was 2017.
@@IKucheINtortIE seems like a toy. Steam is fun but impractical on a small scale. Modern thermal effiency of steam is 80-90%.
This looks very satisfying to build
this is actually a reupload in upscaled hd (from 2012 ish)
the company has not sold any engines to the general public yet its all prototypes
Best 100 Science with the violin sound
looking forward to next seasons starter piece 'yellow cake'
I have a feeling that this will be a useful tool that will be handy later.
Science Channel admin will you please create a playlist for these segments of How It’s Made?
I like how the engine they showed being assembled was clearly just a dissembled prototype/demonstrator.
I was told that steam engines were only about 15% efficient, even if a triple expansion type - and isn't this engine, effectively, a single expansion? Couldn't they have increased the efficiency by running the exhausted steam into a secondary set of cylinders?
No . I think the efficiency is quite high, higher then a diesel engine for sure
You are correct, a compound engine this size is only about 12% efficiency, it would be very unlikely this single expansion engine could achieve more than 10%.
FYI: Cyclone was never a legitimate company and it is defunct after Jharry Schoell diverted investments into the construction of a new luxury yacht (powered by Diesel engines)
@@robertlindsay9826Absolutely not, the Rankine Cycle can never achieve higher efficiency than the Diesel Cycle, this is prevented by the Laws of Thermodynamics
@@sandervanderkammen9230
Sad that people prey on others looking to benefit the environment.
@@NoosaHeads Anyone genuinely interested in benefiting the environment needs to take a seriously hard look at biggest problem, which is global overpopulation.

Have a great day
BTW... this engine was featured on Science Channel's How It's Made, over 8 years ago...
Which channel do you think this is?
@@General_Griffin I know exactly what channel this is... Just go look at this... ruclips.net/video/w27heVUxDQ8/видео.html
@@Quickened1 Yeah, that's the wrong channel...
If anybody reads this, don't bother clicking on his link. It's only a low quality version of this same video... One that *wasn't* uploaded by the Science Channel.
@@General_Griffin you obviously missed the point... I don't care what channel it is, or how high quality the video is, the point is, that same exact video, produced by Science Channel's, How it's Made, was uploaded on Dec 20, 2013! Which means, since being a bit dense I have to spell it out for you, the technology depicted in this current video is not new, nor has it advanced in the last 8 years!!! Get it???
Would have been nice to see some performance data... Former 1200lb/1200° boiler technician, USN...
from a steam engine design stand point this engine is a toy at best, the single acting pistons, _no lubricant_ (idk what the hell they were thinking on that one beyond it being to hard for them or smthn) and fixed valve openings mean that it would be either extremely wistful of steam and positively anaemic for the amount and pressure of steam it consumes, Stephenson's rocket would out perform it by far if they were both run off the same boiler.
@@crestfallensunbro6001 yeah, looks like a very lame design. Hence the reason we never heard anything more about it...
@Sean Embry Distill it down to chemically pure water, add any desired chemicals to inhibit corrosion, inhibit foaming, etc., and call it feed water. Anything that you don't use for boiler feed simply add some of the minerals back in, brominate it, and call it potable water.
Of course, this works MUCH better when you have steam available in large quantities to distill the water, and you are floating around in vast quantities of rather salty feed stock.
Love these
I was looking to make a steam engine, thanks for this man!!!!!
😂
🤣🤣
Go to Harbor Freight, buy a pneumatic wrench or ratchet, connect the boiler output to the in feed and the condenser to the out feed of the wrench and you have a steam engine.
Best show to fall asleep to
There are few ways this would be clean energy. Geothermal, or mirrors heating up a tank of water, but mirror arrays cook a lot of birds.
Steam is not cleaner because it burns less. It's cleaner because the combustion process occurs at atmospheric conditions where the conditions are not capable of producing the more noxious emissions likes Carbon Monoxide and NOx.
Umm...why do I need a carbon monoxide detector in my house for my natural gas furnace, then? Pretty much all combustion produces CO.
@@TexDrinkwater I probably should have worded that better. CO generation occurs even in regular combustion processes but in WAY less quantities than internal combustion engines. It's a product of incomplete combustion due to a lack of oxygen in the environment it burns within which IC engines tend to create. When I was making that statement, it was under the assumption that the fire was like a campfire at a steady state where it was nearly smokeless and thus burning cleanly with comparatively little CO.
No idea why I'm here at 05:50 am but I'm gonna watch it. Thanks RUclips
Great idea!
I like where this is going
Very nice
so what's the reeve valve for on the top of the piston?
I think I figured out what reeve valve
is for on top of the piston. Anyone correct me if I'm wrong but when the Piston goes in the downstroke I'm sure there's there's some pressure there when it's going in the downstroke so it needs to relieve the pressure
@@willhe86 Close.. The reed valve opens during the up stroke to release the steam pressure into the crankcase. The reed valve is closed during the downstroke.
Nice vlog
This is awesome! Can this engine withstand freezing temperatures? Won't the water expand and warp or crack components? Maybe if you mix anti freeze into the water but I'm not sure if that will interfere with engine operation.
Are you aware that steam is hot?
@@kylesenior I was referring to when the engine wasn't operating obviously. However now that I think about it I suppose electric heaters could prevent damage during down time in freezing temperatures.
@@robotswithryan8348 Fair enough. It seems strange to me to run the system intermittently, but if that's what you're doing. I'm not sure water would pool inside the pistons either when not in use.
@@kylesenior yeah I'm not sure where the water would pool either. One of the examples was a vehicle and those are usually run intermittently.
@@robotswithryan8348 Vehicles seem like a poor choice to me. It would be better for stationary power such as powering a remote home.
i was just thinking about steam engines, now i know how to make one :D
this is *_not_* a good design on steam engine, its missing basic parts like the regulator and lubrication and waists one of the biggest advantages of steam, double acting pistons which give more power and efficiency.
@@crestfallensunbro6001 Im simply sillying around, no sane man would build a full sized steam engine in their backyard
@@Narcrate140 understandable, it just annoys me how bad this one is and still being shown off as if it was revolutionary
where can this be bought
For the best steamer of over forty years, see Ted Pritchard Steam Car. Demonstrated in America successfully.
Nice
Very Well Done, but it ended too soon ! Like all Steam Engines, periodic cleaning of the firing chamber must be performed. How often? Even with re-condensation recovery, some water (or other working fluid) loss is inevitable from leaks and blow-by. What does it use?
What a weird trip
what size is that tubing
This will have an enormous efficiency...
I love your sarcasm..
Harry Schoell was indeed exposed as a fake and his company is defunct.
Balls to the walls!
Me: sees the word steam engine
Also me: Thomas the train?
I wanted to see it actually working. What could it be used for?
given how many basic components its missing, not a lot
This very much isn't "how it's made", it's "outtakes of assembly"
And a British professor talk about science history
Thank you for your scientific exploration show!
Cyclone Power failed as a commerical product. It would be fun to have one as a hobby
It didn't fail. It was failed.
Cyclone was not a legitimate company, it was a classic example of vaporware investment scam and penny stock "pump and dump"
Produces less green house emissions? Makes no sense.. considering regular engines are far more efficient in every way.
Somehow it feels wrong to watch these after a marathon of Hubbgeez
I want one
Neat!
So they made this steam engine to reduce pollution as apposed to a internal combustion engine,but they burn fuel to create steam
*हेलीकॉप्टर क्रॉस में जिंदगी और मौत के बीच झूल रहे वरुण सिंह का भी निधन हो गया उसे नम आंखों से श्रद्धांजलि😭😭😭😭😭*
Hmm. No mention of how the exhaust steam get out of the cylinders.
The steam just turns back into water and recirculates
@@ally-gh3hv not in the cylinders it shouldn't, this engine is just embarrassing a hobby model steam engine form around 80 years ago would be 10x better than this, the only reasonable part are the boiler tubes.
The reed valve on top of the piston opens during the upstroke.
What is the name of the company
Magical happened. Steam engine.
I like some off this
Interesting fact is that nuclear reactors also uses stream engine to produce electricity, the reactor's main job is to produce heat which boils water and turning it into steam which runs the steam engines that then runs/turns the generator
Nope.
the metal shavings at the bottom of the new cylinders. Zero oiling, zero life expectancy.
Less pollution?
Not when you factor in fuel source derp
So, they made a radial engine.
"Put a bird on it"
Now I know
"And Now I Know"!
And knowing is half the battle!
Where's my steam-boat?
Disappointed that they didn't show the dingle arm.
How is burning waste oil cleaner than burning petrol?
Steam power! What a great alternative to fossil fuels, wait a minute....
:D
Anything that burns..."Oh No!"
Actually, the flexibility allows the designer to make choices that may be better than what a gas or diesel engine produces.
Of course, it may be worse. It really is up to the designer and user.
@@dclark142002 the point is we used steam long before ICE yet they are treating it like it's a new invention.
@@cravenmoorehead5636 It's not that they are treating the use of steam as new, but the engine they developed to use it... Problem is, this video is over 8 years old, and it's still nowhere to be found....
What hurts me the most is using flat(slotted) head screws.... I hate these so much.
What do you call this kind of engine setup?
I would say it’s probably closer to a power plant rankine cycle then a piston cylinder cycle. Basically a power plant but the turbine is replaced with the pistons.
Steam powered, piston engine...
awful, its missing like half of the basic components of a steam engine like the regulator and proper lubrication.
@@crestfallensunbro6001 but what if I happen to WANT to sit close to a source of superheated steam with no regulation, no obvious pressure relief valve, and no obvious safety valve?
Perfect engine for the zombie apocalypse
Love most of your content im just commenting here for visibility, the reason no one watches history channel anymore is because ghost shows aliens and fake stuff took it over, same with discovery and car shows. Please for the love of carl sagan don't continue down the path that is expedition x
wow
why they don`t show the steam propelled vehicles in action?
because id bet this engine barely runs, its missing like half the basic components of a steam engine.
My impressed meter is registering very low on this one.....
Why is this engine so beat up? Look at all the gouges and chips in the paint 😂
Who invented the train?
The first trains were camel trains and the like, 1 to 2 thousand years bc.
The first steam train was by Richard Trevithick in 1804
Seriously.. a couple of nit picks. 1) even a 'closed' steam loop has losses and you will have to refill the water. 2) water is NOT a lubricant. You will need some very light steam oil.
Genuine question - if steam engine is so efficient and greenhouse friendly, why isn't it more commonly used?
Because it's not efficient or greenhouse friendly.
It is and it isn't. Thermal power plants (coal, natural gas, nuclear, biomass aka wood, geothermal, etc) use steam regardless of the heat source, for the most part.
The most efficient way natural gas is typically burned for power, for example, is with a combined cycle gas turbine, which is a gas turbine (similar to a jet engine but optimized for shaft power, not thrust), and a steam turbine combined together. The waste heat of the gas turbine heats boilers which drive the steam turbine. Gas turbines are far more efficient when driven with high temperatures, than steam on high or low temperatures, but the waste heat is still quite hot and can still be used for steam power.
As for the small scale shown here, I doubt that steam engine is all that efficient, although I could be wrong (after all, that is quite the super heater in that boiler). Highly efficient piston steam engines are quite complex and maintenance heavy. When steam locomotives were phased out the diesels that replaced them actually were less efficient, but their far lower operating costs and greater flexibility made it quite worth while. Today, small internal combustion engines are probably way more efficient simply due to higher combustion temperatures, and certainly less maintenance intensive, but with that steam engine shown lacking any real control gear you would usually expect for throttling or achieving efficiency at anything besides flat out operation, it might not be too bad for maintenance cost. The generator used for charging off grid battery systems looks like the most interesting application due to it not needing particularly fine control. Btw, when they said in the video that the water was the lubricant, that was probably a flat out lie. The (I assume) graphite pistons are probably the lubricant, graphite is a good dry lubricant.
Oh and emissions. The low combustion pressure (and probably low temperature) reduces things like nitrogen oxide emissions, which is a big part of acid rain. Nitrogen oxide free in the air will eventually oxidize to nitrogen dioxide (once cool), which then reacts with water in clouds to make nitric acid. This has almost nothing to do with greenhouse gasses as CO2 is the primary greenhouse gas by a long shot in this case.
Hope that was somewhat helpful and that I didn't get anything too wrong.
Because governments are made up of predators that believe that the only solution to any problem is you losing your rights. Hence the climate hysteria BS.
is this better than just steam turbine?
nonetheless, neat design ;)
Define "better".
I’m pretty sure water is not a lubricant

steam engine lore
Anyone know how to buy this engine in the US, and the cost?
you dont want _this_ steam engine, you might want a steam engine (they are great) but not this one, this one is god-awful.
@@crestfallensunbro6001 it look expensive, I look at their website but no price were giving
This engine is a useless scam, if you cant see that from this video then you should probably stay far away from the technology.

screw toob algae rhythm is total poo
cars should use this and get rid of gas
I think this would be infinitely more useful to have in a survival situation then all those stupid guns ppl collect.
Lets be honest, none of us seached for this😂 Lets be honest, none of us seached for this Lets be honest, none of us seached for this
So theoretically, it's an infinite power source through solar energy? Use sunlight to heat water to vapor and charge a cell for night time. And we can use atmospheric pressure to reduce the temperature at which water boils.
You might as well just use a solar panel at that point.
Haha you must be joking, or maybe you just love to overcomplicate things while pushing efficiency down the drain.
For about 1000 hours apparently, thats how long the engine is expected to run. Thats why they are not in buisness anymore.
@@dylanm.3692 solar panels have a maximum theoretical efficiency of 33% and few even break 22%. They also lose efficiency as they heat up. With this thing, the hotter the better, so with a mirror like they showed you could run air conditioners in the summer for a far lower initial investment than solar panels, and get peak energy output in sync with peak demand.
@@AM-ce4of That's not far below the efficiency you can expect from any steam engine. The lower efficiency from a solar panel is far outweighed by its simplicity, cost, and as The Bamboozler mentioned, service life. Small scale steam went obsolete for a reason.
TL;DR, this might have better thermal efficiency, but photovoltaics have better overall efficiency.
Let's see now...what company was that again? Oh. They forgot to mention it.
Cyclone turned out to be a scam... defunct now.
wow that was a lot of Green Washing. "The fosil fuel burns off compeleatly"... yah, into greenhouse gasses you numbty, it doesn't just disapear.
