Z8 engine

[dzuari]

looks a lot like a wobble plate engine

[MrBurningBass]

whats that ?

[peepeevagi]

Kinda useless considering it's steam powered and extremely complicated. Sure, you can call it 'simple', but there's at least a dozen simpler designs that produce good power. The only thing this thing saves on is space, but wtf are you doing using a steam engine in the first place if space is an issue?

[knowledgemonger]

@peepeevagi I don't even think it saves space. The mechanical parts add up to more than a crack would for a radial design.

[Born2BwastedUSMC]

Thats one hell of a cocktail shaker you got there.

[MrElcojo21]

sounds like a fish pump..

[USCisgay]

looks like a giant sex toy

[surinderdhiman]

Wow ! superb ! you are blessed with a highly innovative brain. Keep it up, dear.

[Littlemac181]

the 50hp one, thats only 13 less hp than a smart car. and twice the amount in some old Citroen! it could work haha

[madjimms]

Looks terribly inefficient.

[dpress95]

if this was modified to run on gas, or even better diesel that would be amazing

[01Toecutter]

@dpress95 The whole point is that it DOESENT run on fossile fuel???

[AxeBusa]

how is the steam produced?

[sc38converter]

steam engine, nice just like the old steam locomotives but on a smaller scale

[bulletproof2353]

so what is the benefit ? is more efficient than a normal design? can you give some efficiency comparisons between it and other engine types and designs

[craphappychinesepapy]

I have a question for the enviormentalists...

If electric cars need to be plugged in to charge, arn't we using more power from the sub stations and power plants, and therefore consuming more coal and oil? Bare in mind, this is a question. I have no idea of the specs, or how a hybrid works.

[mcgrath9]

@craphappychinesepapy so you found out that electric cars will be charged off a power grid that is run primarly by burning coal. dont tell anyone . its also good to note that if you have an electric car with a 100 mile range may only have a 50 mile range in the winter time due to diminished capacity of any battery in the cold,and dont run the electric heater in the car or you may have a 25 mile range, but if you charge it off a solar panel than its truely green.

[TheDeviousSniper]

@chezgreens can you recirculate the steam back into the system with this design?, looks like a lot of steam is being wasted.

[crackonpack]

Can it be used for Dildo machine?

[andy232005]

@crackonpack 30HP Dildo? "Wow look at her Go!"

[jumpercable95]

looks to me a person with minimal expertise that the center part move oddly and could be a point of extreme mechanical failure

[shawnmccori]

I am going to build a engine that runs on your own farts. You sit on the seat and fart and fuel your car at the same time. Free fuel LOL.

[1BustedMyth]

Incredible

[steamerandy]

It's neet to look at. But this fellow doesnt know what he is talking about. A steam engines efficiency is basicly deturmined by expansion ratio unless over expanding below exhaust pressure where it's efficiency goes down rapidly. A large engine with a high expansion ratio will use less fuel then a small engine with low expansion though both engine output the same power. A small high reving engine can produce the same power as a large low reving engine. More to power then pressure and volume.

[DRGIZMO29]

fap fap fap sound

[thercpoop]

giggle giggle giggle giggle giggle, yeah

[briantracy1324]

Way too complicated ,, the 6 cylinder engine is basically a frigidaire "A6" air conditioning compressor , 6 cyl wobble plate design with the external case skeletonized ... the other variations just add and subtract cylinders... My question is simple .. is this a more efficient design than your typical standard double or triple expansion engine from 150 years ago? Reliability isn't a concern with the old engines ,, fill the oiler with a few spoonfuls of bacon grease and they run forever.

Нетехнологично

[mikesmullin]

you need to open source this. post it on kickstarter com and get paid, but don't let it rot on the shelf.

[1BionicRooster1]

But, will it blend?

[01Toecutter]

@1BionicRooster1 Nice you are truely contributing with something new and worth taking up space on a server.

[ieatpeas24]

Too many moving parts .. look at an old steam engine ... piston crank valves .. those things run like butter ... this thing will shake its self to pieces



[IonOtter]

@ieatpeas24 Agreed. It's barely even running, and it's ready to start dancing across the ground. WAY too many moving parts. Looks and sounds neat, though!

[azra00009]

The real name of this engine type is axial engine

[lowcarb85]

how much torque can you pull off this thing?

[djbarcode5xyz]

That sound is just beautiful!

[Leojpjc]

Exelent for a steam punk car design xD

[djbarcode5xyz]

@Leojpjc That's why I'm here ;-)

[djohnston36]

One of the video captions says this is a 'green' engine. So I assume the steam is coming from a 'green' source?? (No engine is 'green' if it is less efficient, still uses fossil fuel or other non-green energy, and does not use recycled material).

[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!

[MrMatidor]

Nice work. What's it's efficiency?

[crapthisisalongusern]

Hi, I got to say that the engines are a work of art and indeed uniqe. I am currently working on truck and thanking about converting it to steam power. Your z-8 cought my eye and looks impressive for its size it looks like it could really put some power out at high rpms. However the tork value is in question being the fact that the engine is an indirect drive ossolation engine. How big would it need to be to put out 800 to 1000 pft. I would love to here from you as soon as you can get to my ?TY.

[andytheweb]

Steam's grey not green

[aaron2656]

hey matie how much would one of these cost and what are the dimentions of it iv got a project goin and this engine would do well as the drive source

[azra00009]

Did you make this motor by yourselfe ?

[azra00009]

could you tell me how does this motor convert translation of piston to rotation of shaft

and also could you give me some link where I can find out more about this tipe of engine

[the1cyrus]

whats the price of one of these?

[nihil4498]

@the1cyrus Check out the website called greensteamengine. It´s quite interesting.

@the1cyrus Check out the website called greensteamengine. It´s quite interesting.

[steammaniac314]

is there a way to reverse it?

[QuattroStig]

Whats the longevity of the engine? Do you have maintenance intervals? Let me know

[biljka2]

From Your site

"When the exhaust is condensed through a heat exchanger whereby the condensation process is used fully by heating water, space and distilling water, for example, the efficiency can be in the 70% range."

What do you mean by " heat exchanger"?? Heat pump??

[PimpXXXGuitarist]

30 h.p. could produce 6,000 KW EASILY.......

[PimpXXXGuitarist]

50 h.p. ... DAMN i can't wait to get my millin' machine...

[becoming29]

What kind of pressure are you using to run this unit?

[grvmkr]

Please contact me on grvmkr at gmail for I would like to talk to you about a business idea involving your engine.

[lososian]

could this (z8) be used to power a vehicle? I'm thinking maybe compressed air motorcycle or something. 30hp seems like enough....

[chezgreens]

There is no reason why this could not be used for a vehicle. It's being used in boats now.

[raoke69]

@chezgreens How large of the ones being used in boats though? Packaging this thing in a motorcycle or car would be a big issue without knowing what else is needed to get this engine to work. Besides that motor, could you list out what is needed to produce the steam it runs off of?

[porpoisefathom]

@chezgreens please post videos of it as a pime mover in boat...whats the torque and rpms of this engine?

when i look at it( hard from a video) seems a little underbuilt for a true 30 hp...steam engines excel at torque. but your axial design seems limiting- a classic steam engine would be 30 hp @ aprox 500 rpms therefore 30 x 5252/500 = torque ft-lbs = a whopping 315 ft-lbs of torque!!! thats about the strength of a 500 hp(modern diese)l! r u gonna tell me this is equivilent??

[thra5herxb12s]

@lososian Where would you store enough air.

[OpinionsofDave]

@lososian The Toyota Prius has 47 HP and is able to move at freeway speeds.

[bujie2008]

@lososian it sound like a vigina

[WorldStove]

i wish i had half your skills.

[TheSolarBloke]

Great looking engine here. Say... is there an independent engineering assessment of the Z8 or Z12 under load conditions that we can access? C'mon Robert don't hold out on us now? We really, REALLY want to see this, and you know it's what Commentors are asking for. Cheers.

[scarmenl]

I've tried to go to your web site a number of times now and it keep showing no connection. Is there some other way to contact you?

[chezgreens]

Just put "steam engines" in Google search. It's on the first page.

[twistaspliff]

Great looking engine, but I think your 30HP claim would hold more water if the engine was actually connected to some kind of load.  Lets see it run a big gen head under full load. Should be no problem for 30HP.

[chezgreens]

With steam engines, all you need to know is the steam pressure, volume of the cylinders and the number of cylinders and you can determine the power. This engine can be made any size to fit your power requirements.

[porpoisefathom]

@chezgreens this is incorrect -you need to know all the above plus its continuous rated rpms. the temp of the steam, and from this--it's torque ratings. good machining work though.

[georgiahoosier]

The multicylinder engines look terrific! I take it you can still get that kind of power out of lower pressure steam?

[chezgreens]

Because there are 8 cylinders, even 20 lbs of steam will produce considerable power. The engine starts on only one pound of pressure.
