green steam engine

[geometry001]

MOST ADORABLE !, PIECE OF THEORY BROUGHT TO PRACTICAL,..COULD GO FURTHER IN PROCESS FOR A BIGGER VERSION AND I AM SURE THIS IS A SPRING BOARD,...I COMMEND YOUR EFFORT.,,

[majsharps]

I would order 2 of these today as in theory it looks to perform.But for 2 yrs people appear to have the same reservations and have asked to see a video of it working under load. Still NO video here or on your website! No feedback online as with other generators etc.Does this work as well as stated? Pastoral energy has a lic agreement but their website not complete and ph # disconnected. WTF something not right here!

[pigeonflipper]

would have been nice to see it running,,

[Cryo2005]

Very interesting design! Love it :)

[yousri71]

Hi, the flexi rod need to change frequently?

[ipadize]

its not green...

[59n1tr0n72]

hi, what are you using to generate the steam? Thank you.

[ValmisFilm]

looks stupid, too many parts taht can break and it vibrets a lot

but still, something different, I like that...

[byugrad1024]

What a joke. Any person that is mechanically minded will refute the claims of "high torque" by pointing out that the two hexogonal end plates are spanned by long (narrow) rods. Any amount of significant torque that this would generate (as claimed) would result in bending these narrow rods at all 12 locations, (effectively rotating one end plate with respect to the other). Green? How about brown. For crap.

[Midnighter169]

wait do you get higher power and speed from smaller pistons?

[Moneymax3001]

Well well,,, your name is green... it's my guess you'll be pushing up some green by the time this gets to market... interesting design... applaud your machining ab-littles.... looks likes there is a bit of vibration and did you use steam to do the 120 psi test or air?? you know steam has a tendency to lower metals abillities to to withstand wear and pressure... maxwell...

[ThouHastEnabled]

Pretty much all of the video's posted on youtube about steam engines and what not have people making very rude and presumptuous remarks. If you disagree with the engine, post a question without being an asshole. These uploads are made by people who have a drive to make something better. How many times have famous inventors failed before they made their idea work? Cut these people some slack for fuck's sake. I dont see any of you people getting off you're fat asses making anything worth a shit.

[bobzulu88]

Hello Mr. Green, nice invention. Thanks for making some plans available. Nicer yet wold be if you made plans or builds of the more sophisticated models available. Is anyone building these in your license yet? Do you have metric plans? And how does the steam recycling work - how do you get cold water back into the pressure tank which is making more steam without letting the pressure out of it?

[ttelgrande]

your a very funny guy. we love your cartoons! now show us this toy connectect to a generator with something pulling some load. it is easy to go round and round. but lets see this thing go up hill!

[telesniper2]

Looks like it is about to fly apart at any instant!

[Bekzat95kz]

I can't understood how this genereAtor working can you give me the site or information about working principle?thank you!

[dickiedick1962]

I was looking for this, I had an idea, and had no idea if this would excist at all!

Any way, I live far up in Sweden, and our winters are kinda long, and almost no light!

My solar panels work fine in summer, because the sun is there almost 24 hours. Because I live fare in the forest, there is no electricity, but a fire place that burns almost 24 hours! Idea is to capture the heat, make steam and run a generator!

[adamthehunter]

I like the possibilities of this, but how much are the machines, and where could one order one?

[CreQ]

By the way the energy still has to come from somewhere. The steam or pressurized air has to come from somewhere. What you need to first focus on is an efficient and environmentally friendly way to PRODUCE the energy instead of HARNESS it, we already have many ways of harnessing it, it is the production and supply of the energy that need focus. No matter how efficient this engine or any other engine is, its power has to come from somewhere, which is usually damaging to the environment.

[CreQ]

It's green because if you rode on something powered by it you'd get sick from its bad resonance..I've never even made an engine before but I know that vibrational resonance is an issue..and partially why 4cylinder engines were/are so popular..also you are losing potential energy that could be extracted by these means.

[khaled6100]

a lot of vibrations :(

[porpoisefathom]

yes true- less friction-- but more vibrational problems--thus its the same wear rate regardless--its 6 of one half dozen of the other...the only advantage i can see is use of less oil to lubricate.

i prefer classical steam designs slower turning- ie more torque/rpms=less wear...but its all good when it comes to steam.

good job.

[neonbluen851]

i've always wondered how to build one of those

[Zappyguy111]

It's cool but it's not very green. I can't see it putting out too much torque. I'll just stick with my turbines.

[Nightmare1066]

This engine sounds interesting but am sure that the price of one such engine is enough to reconsider your interest.

[COD5252]

red steam engine

[blqkvo]

Coolness!

[sailingsolar]

What is it operational live, in hours of run time. Where moving parts are involved, they will ware out over time. Your next step is to run it continuously and see how many hour it runs until failure. All you have shown is that it works, in construction. If this can run 24/7 long enough the design is viable. If it only runs a few thousand hours it proves that it is not a practical design but a impractical for application. SS

[PimpXXXGuitarist]

biowaste... 10 h.p. ... hmmmmmmmmmmmmmmmmmmmmmm....

[roaming2]

I love how the engine sounds.

[Polypropellor]

I am impressed...very well made and innovative.

[universalmoor]

very good work. and the parts all work in the open air. i c no grease? how did u come up with this idea. i have a million uses for it in the home that would eliminate all utility companies!!!!!!!!

[atvheads]

Whats green with it?

[chezgreens]

It runs on anything that can heat water- Solar, geothermal, bio-waste and my name is Green.

[MacsCanfly]

what are you gonna run with it

[ExtraSilver]

cant a normal steam engine do that do?

[cookman283]

@chezgreens Things going to blow itself apart with all that eccentric rotation.

Wouldn't want to run it too fast.

[DAKOTA56777]

Any steam engine can run with any heat source... and the old ones in my opinion they look better too.

[AlbatrossDude]

@chezgreens Nice answer.

[PogodinPavel]

@chezgreens Let me explain what "green" means. The worst problem of today's technologies is heat. For example, you heat some water by an electric cattle. Electicity is got from burning gas, or some sort of coal, or anything like that. Today only 40% of energy of fuel becomes electricity. The other 60% goes in the air. Then, when being transmitted by wires 25% of energy heats wires. And the wires heat air. Finaly all of the rest of energy becomes heat in the cattle.

[PogodinPavel]

@PogodinPavel Then the heated water heats air, outside or inside of humans body. I want to say, that ALL of our energy we use to heat the environment. It is impossible to be avoided. But it is more effective, if more of that energy does it while comleting some useful process. That's why steam engine is never "green". More than 97% of energy is wasted BEFORE any useful process it has to compete. And only 3% of energy of hot steam becomes energy of rotating wheel.

[lowcarb85]

@chezgreens you have a cool name.

[TheManFromAlaska]

@atvheads

The inventors name is Robert Green, thus he named it the Green Steam Engine.

[FluxAscender]

I'm sorry, but what will this motor actually be able to do? Just looking at the design, I can see that it cannot possibly produce more than a few inch-pounds of torque. Any kind of working load would stall it almost instantly.

[chezgreens]

This engine runs a 3 to 5KW generator with ease. The engine has 3" cylinders. That creates very high torque.

[Joe11Blue]

@chezgreens Do you have any Dyno plot's for it yet? If you really want to prove it's viable you need those.

[AlternativePowerMan]

@chezgreens

Can we see a video of this thing running a 3 to 5 KW generator, with the power load clearing showing 3 to 5 KW?

[rexman92]

@chezgreens thing a green steam could be made so it be on a steam locomotive like so?

[madelainejulien]

@chezgreens sell it to me!

[qwertyui90qwertyui90]

@chezgreens

I call bullsahot to this generating 3-5kW.

[BriKuz]

Okay, where's the inovation? it's a swashplate motor, used for decades as both an engine and a pump. At least the AXIALRadial has a cam instead of a swash...

[chezgreens]

The "flex rod" mechanism that requires no lubrication and is extremely economical and durable, the swivel cylinders with straight-line movement that reduces friction and allows for light-weight disk pistons sealed by simple "O" rings and a valve system that allows large ports and low friction with reduced mechanisms. This results in a very economical and light-weight engine with more power per pound and no lubrication requirements other than steam.

[TheSolarBloke]

Notice on your website the (very handsome) Z8 has a flywheel. Thought that anything 3 cylinders or above did not require this. Can I ask what made you reconsider this, and will be posting videos on YouTube of the Z8 and Z12 soon?

Cheers

[chezgreens]

No flywheel is required. I use it as a flat pulley and a hand brake. Z8 video is on Utube. For a link go to my web site.

[krimskrams]

i would very much like to build one, where are the plans?

[ollieoniel]

haha i like your design its very cool looking

[kulas1001]

could you please upload some physics or mechanics on how the engine works pleaaaasssse. i really need it in my energy conversion subject presentation.. thanks a lot

[kulas1001]

like as the other posters here say

silence the doubters by posting with constant loads videos here

thanks

[byugrad1024]

@kulas1001 Silence all the doubters by hooking this to a dynamometer and producing the results printed out on the screen.

[Lubobuba]

I would be very mad in case this thing is just a blow, and the plans are not helpfull.

But, interrestingly, I didn't see any negative feedback nowhere in the net, which leads me to assume that this concept and product might be worth a try.

[McGeeDwarf]

It doesnt work well, its just using water instead of fuel which of course will cost you unless you can take from a river or lake nearby since there are water bills for water service. Not using lubricant will also cause damage short and in the long run especially since the parts arent strong enough for long term usage. The locomotive type would be far more efficient and would provide more speed and power with less usage.

[chezgreens]

Other than in the video, I always recycle the water. The engine pumps the condensed steam back into the boiler. On the contrary, not needing lubricant is a great advantage. It does not foul the boiler and the steam can be condensed for distilled water. The straight line piston movement eliminates the need for lubricants and eliminates wear. The piston rings are "O" rings. not tight metal rings.

[chezgreens]

Balancing the engine is simply done by adding weight to the crank arm. All engines need to be balanced and fasten down. Notice that the engines in the video are not fastened to anything.

[definca]

Need to see the specs as to power vs energy used to create that power. Has some vicious balance issues.

[Rapido3d]

I think my biggest worry with this as a usable solution would be the wear and tear especially on the bearings, how many hours have you run one for? how many parts broke or wore out in that period?

[chezgreens]

Because of the straight-line movement and having only one bearing, There is very little wear and tear. No parts break. Period! Anything that wears is replaceable in no more than five minutes at very little cost. You never need to change oil. There is no oil.

[steveBB30]

so sound's like you are using hydrostatic bearings floated by steam/water ? It's a really good solution if you are.

[megadeth22885]

my question is.. whats the thermal efficiency rating on these engines? and should it be scaled up, or cylinders added to achieve 20hp to run a small car on? personally i think youd get better efficiency if you recycled the steam and pushed it through a turbine

[chezgreens]

Turbines require very high pressures. If you are prepared to make a boiler with pressures required, don't get into an accident. I always recycle my steam unless its just for a video. The thermal efficiency without recycling the steam is only about 24% on this engine.

[VantageAlaska]

Do these 10hp Plans pertain to The Double valve model in this video or is it the old one in your other videos??????

[chezgreens]

The plans are for a home-shop version with a single valve.

[seannaveed]

do u sell these engines?? if you do how much it will cost to buy a 10 hp engine????

[chezgreens]

Five different manufacturers will be offering this engine in different forms in the next year of two.

[ts22360]

Can you please show this running under a proper load? There's nothing here or on your website to show that the unit can indeed produce anything like the horsepower you suggest. I'd love to believe that this is a viable and simple steam engine that I could use for my projects, but without adequate empirical data, this remains an idea rather than a properly engineered application. Please show us something that we can use, especially when you're charging for plans. Thanks

[chezgreens]

Showing power on a video is not that easy. One can always say it was faked. Calculating the power of a steam engine is easy. It is not like an IC engine. The formula is simple. Think of the word PLAN. Pressure X Length of stroke X Area of piston X Number if power strokes per revolution X RPM's / 33000 = HP.

You can now determine the approximate power for any size steam engine you are referring to.

[VantageAlaska]

Why dont you show it running at 125 psi's?

[chezgreens]

At that pressure, you need to have a load on it. It would be like putting your foot to the floor on your car in neutral.

[VantageAlaska]

well can you show how many watts you can pull at 125 psi, have you maxed it out, electricity wise? What is a constant watts Max? continuous? with a good hot flame? I'm looking at continuous wattage? 10hp? like a diesel generator?

[chezgreens]

In general, 125 psi produces 9 to 10HP. That will run up to about 7KW generator.

[epicdeuce]

Load it up!

[johnhtodd]

I would agree. I've still never seen one of these engines running under anything other than minor loads. Put a 7kw generator head on it, hook up the generator to an electric water pump or a fan for constant maximum load. There are lots of naysayers out there on this design; put that to rest with some real-world loads on a unit and tape the results.

[epicdeuce]

Exactly, if this guy wants some exposure on this thing put something on it. Something everyone can relate to. Creative mind made this, however a creative mind needs to make some marketing

[defenderofliberty]

Nice!
