Hi. I love your channel. I even like your workshop more. Everybody has an "media ready" workshop, but yours is just a WORKSHOP, love it!! :)

[@samhughes1747]

Love your stuff, dude! Seriously. I'm convinced that, at least in America, primary education only succeeds in convincing students that they can't understand science and shouldn't bother trying. Through every video I can think of, your focus has been on making the science of the matter accessible, while generally doing credit to the inherent complications. It's masterful, from a pedagogical perspective. You've been directly the cause of many messes around the house, for me, and quite a few foul odors. You fool me into thinking I can science, and you do it so well that reality plays along. P.S. this could totally work for a 3d printed motor. The limitation has been that precision multi-material is really hard, and conductive filaments are total trash, but with some high-temp materials, the high resistivity of the ProtoPasta filament would make a decent heater. I'd have to experiment with printed thermocoupling, but three stacked loops pneumatically driving a Wankel motor, could likely provide decent torque. Go lighter by replacing water with something that has better expansion characteristics, if needed. by adding a magnet or an oscillating coil at the rotor tips (whatever you call that part in a rotary engine), and N number of printed stator coils, where N is prime or not having 3 as a factor, one could even produce a stepper motor.

[@judyofthewoods]

I like the magnet idea. Reminds me of the "shake light", an LED torch with some magnets and a coil, and as the name suggests, you shake it. Can't remember if it had a built-in recharbale battery or if it was just a "dynamo" type light, a rather a bouncy one, as with the wind-ups. However, the fluidyne powered by the woodburner stove could give a steady LED light. I'll have to dig out the old fluidyne plans I bought pre internet and stored away as I couldn't see a good use for it at the time.

[@stevetobias4890]

Got to love the things you can do with a fernel lens and the sun. Get the right focal point and it gets bloody hot, I have seen them melt metal.

[@ThinkingandTinkering]

there is some energy in that!

[@garethb5729]

I've just had a thought about the issues with this build. What you need to do is, set up a zvs driver around the hot pipe. Then you could heat it using electricity. If you placed a magnet in the water tube that rises and falls. You can wrap cable around it. Thus creating a free electric device. Let's just take a second to enjoy this chocolate teapot. Lmao I'm sorry Rob. What I really ment was. Wow amazing . Thank you for being awesome and sharing your awesomeness with us.

[@aomanchutube]

I made a fluidyne a long time ago when I first started working. I used EMT, that steel electrical tube used for house electricity wiring. So the diameter was slightly over half inch. It has a nice 3" bend at the bottom. To cap the tops I chucked a 1/2 copper tube in the lathe and spun each end into a bell. Each bell got connected to the other with a 1/4" copper refrigerator tubing. So the idea was to make the body less conductive than the regenerator. Heat conductive. I used brazing to connect the pieces. Finally on the output I had a T. By placing a 1 way valve on the bottom leg of the horizontal T I was able to pump water up to 12ft. At 12ft the water barely made it up there. It would start easily, but it was a pain to restart without refilling carefully. The air pocket inside the regenerator was either evaporated away or maybe dissolved in the water so the level was too high or too low. Plus the heat was a soldering torch at full fire. I was eventually going to try placing a piece of styrofoam on the hot side to insulate the gas from the piston. Also was thinking of making the Pistons larger. I was thinking that maybe one cylinder could be larger than the other. Oh it had enough pressure to drive a water fountain.

[@ThinkingandTinkering]

[@TabooRevolution13]

[@mac-qt3wd]

Hi rob nice work, can I ask a question to you or your viewers about electrolysis please? Is there a formula for how much power/Watts you put into the electrodes as to how much hydrogen you get out. I ask cos I was actually trying electroplating for the first time and noticed that a fair lot of bubbles were coming off and I was only using an old style car battery charger as my power source, guessing 40-60 Watts ish, maybe. Cheers

[@RobertofLadywell]

My friend and I built a fluidyne device many years ago and was told of a tool that could help you tune it. The years have gone by and I can't trace it - can you advise where to get hold of something similar, please? I would love to use the difference in temperatures between the inside and outside of our conservatory where the temperature difference can be high.

[@azlandpilotcar4450]

Can't beat this for simplicity, but cold soldered copper joints would eliminate that cooling bit (or allow you to move the cold bath to the cold pipe) without being all that more complex. Maybe even allow for rocket stove levels of heat input. Great demo.

[@ThinkingandTinkering]

for sure mate

[@CEGBrevival]

Could the fluidyne be used as a central heating pump? Valves could convert the oscillatory motion to a pump.

[@rayg436]

[@AutoNomades]

Hey Robert, i was checking how to do flat heat pipe, and i found a tech derivated that is called "oscilliating heat pipe", and i immediatly thought that it looks pretty much like how we could build a solar fluidyne motor/pump not needing a concentrator !! What y'all think about ? Cheers !!

[@jamesross1003]

Great little engine. Great job with the build. Isn't this basically a thermoacoustic engine using water rather than air as this would still work with air? Would be very interesting to give this a go with a cork as you mentioned, but with a rod and flywheel like in many thermoacoustic engines. This one is so much easier of a build than one with air, but also much slower.

[@mikaelfransson3658]

Now I Just love it! Then You show this Shittypretty engine, how do the max be in output? Maybe a membran on top! more magnets a few iron washer between or magners on both side of the cork! This is the greatness about your films Rob! And maybe the reason we look at free energy films! We love the play how started in our brains! Just❤it!

[@ThinkingandTinkering]

you just never know where a thing will lead you if you let it mate

[@reypolice5231]

Could the thermal couple you just showed before, be incorporated into this? I know it's way more mass but on the hot side could mass be mitigated ( perhaps) by short sections of copper tube and ( iron, steel, aluminum) , other metal stacked on the hot side and cooling fins, Or water tank on the Cold side to increase the differential?

[@ThinkingandTinkering]

well I suppose you could. mate but I am not sure why you would - what are you thinking here? what is the objective of including it? cheers

[@robertchristensen5251]

If you used a linear fresnel lens I think it would be an efficient solar engine, and you could bend it around the pipe so you don’t need a solar tracker.

[@Nissearne12]

Thanks. I works on a different variant of water pump stirling engines where my innovation have ideal discontionous movements of the floating displacer and isothermizer included. You can se my work on my channels. Some fluidyne on wiki have both isothermizer and a floating insulation body just like mine engines but my innovation have a up side down under water Line Ringboom innovation. One tip i figure out is there is an intressting material I start to testing more for this isolation material called Foamglas that may also be useful in fluidyne stirling with floating isolator on the hot side. I have animation and some working prototyps as well as when I start working with Foamglas this time

[@ryanjamesloyd6733]

oh cool. Seems like if you used flex copper, that would be easy to wrap your hot end around something like your rocket stove. Do you know off the top of your head if there would be any benefit to having your cold side pipe run through a water bath or with a heat sink for better/faster cooling?

[@ThinkingandTinkering]

I imagine it would help maintain the heat difference across the engine mate - a Fluidyne is a type of Stirling engine

[@DrBretPalmer]

Embarrassingly I couldn't get this to work, ahhhhh! No idea why I can't get it to work. Using 15mm copper tubing. Using a blow torch as a heat source. Maybe bigger copper pipes?

Cool, any idea how low a temperature difference a fluidyne could work on?

[@ThinkingandTinkering]

no - but it can be pretty low I believe

[@zenmanproject]

How about with something like R-134a (Car air conditioning refrigerant)? At atmospheric pressure it boils at -15C, but if you pressurize it, you could raise the boiling point to whatever you need it to be. The other way would be to use water under a vacuum and lower the boiling to whatever what you want the boiling point to be. I guess the downside is you would need the top end of the pipe sealed. I assume RMS has it opened to the atmosphere. I'm not sure how that would affect this engine.

[@David_Mash]

@Zenman Energy I have seen comments that evaporation is a necessary evil with the fluidyne

[@zenmanproject]

​ @David Mashiah The evaporation from the hot pipe to the cold pipe, sure, but not to the atmosphere. When the heat is removed, it will change back from gas to liquid and no fluid is lost. Stirling engines commonly use hydrogen and helium. They certainly aren't exhausted to the atmosphere with each stroke. I bet all it would take is an appropriate sized heat exchanger and then the system could be sealed up using whatever heat exchanger fluid you want.

[@MichaelDobbins]

@@ThinkingandTinkering That makes it very interesting. I have an idea in my future projects file to run a loop through my attic to drive a sterling engine generator. This is simpler. 100' pex, a T and a few Els, fill it with water and auto radiator antifreeze, a float, magnet and coil. I have a scavenged baseboard water heat radiator that I could use to keep the cool side short. Probably
