Super wat je aan het doen bent, ik had hetzelfde idee om via de orginele tekeningen de turbine te gaan nabouwen. Ik heb het idee dat je nederlands bent dus vandaar mijn reaktie in het nederlands :)
Impressive work! I'm interested to see it done with proper materials to avoid unnecessary vibrations and efficiency losses ... and also to test it in reverse - assuming the turbine is normally connected to power generator and you run it in reverse - as a kind of fan. Also while testing it in reverse a noise measure could be done.
The idea is that the second stage assists the first one in what Tesla calls "compounding", but honestly I don't know what it will do, that's why I built it to find out. It does seem from the British patent that the volute and circular turbine somehow fit together, but maybe that's just a coincidence. Only way to find out is to give it a try :-)
@@Waveguideon steam I think the pump could help the turbine getting a higher flow rate en therefore a higher power en efficiency at a lower temperature , it's like a negative turbo charger , only if have to displace about 1/10 or so of the turbine exhaust flow rate, this can be done of you place a economiser (regenerative Heat exchanger) in between the exhaust of the turbine en the inlet of the pump which in turn is connected to a vacuum condenser en from that let the condense water Counter flow Treu the economiser In between the pump en turbine so most of the latent heat of the steam is recaptured , whitout the pump I've successfully done this in my cryophorous en the Tesla mechanical oscillator system !
You should talk tto CharlieSsolis he is using tTesla'spatent and is doing R&D to make a production turbine so everyone can make there own clean energy at home. In my opinion he is the expert on all things tesla trubine.
The system here is based on stage one causing the incoming fluid to be wound tighter and tighter along a centripetal path which is designed to cause a velocity increase of the moving fluid - like a vortex plug hole effect- which creates increasing suction into the casing . At the exit from stage one the fluid will be spinning and rather than just allow the fluid to chaotically dissipate into the outside pressure zone , the stage 2 part of the turbine allows the spiral path to continue , although now unwinding it centrifugally- this must assist the speeding up , and hence the suction effect, in stage one . In this video the inside of the casing is shown to have circular ridges , according to Tesla , whereas in Paul T's stage one replications there seem to be spiral grooves which must be better and enhance the centripetal pathway [ Although they will wind the other way in stage 2] . Should these be Fibonacci / golden ratios? Did Tesla ever mention this -do you think ? Also the cold steam aspect of all this seems no longer to be centre stage [ excuse the pun ! ] in this replication work .

Hey, thanks for the detailed comment! I made these mini machines to better understand the principles Paul was sharing. They are definitely not able to handle steam (found that out the hard way with a completely warped rotor), but cold steam could possibly work. For me though, these were just learning tools, not serious experimental equipment.
Really nice job man for such a small turbine! I dot not get how you build your discs? Dit I see pins across the discs? En What disc spacing dit you those for your build, Jeezzz The white turbine thing is Indeed a peace of trash 😂 en it's not even close to the patant, for the nozzle i choose the one from the (aerial apparatus patant) because you can tune the slit en therefore the speed for the incoming working vluid to a maximum rpm restriction whit about any pressure,
Hi Oscar, the disks were individually 3D printed, then epoxied together onto the shaft. No rivets, just portrusions to keep them spaced nicely. And that adjustable nozzle is great indeed, would love to have that for future versions.
@@Waveguide alright nice to hear that I thought I saw some pins in the beginning of the video where you showed the rotor , how about your disc spacing? I see now you replicated the original patant version of the turbine even whit Labyrinth seal you don't see that very often nice job ! , I decided to not do it because i had the feeling it makes more room for leakinge 😅 as mi spacing is 0,5 mm from the casing to the rotor I have 13 gaps of 0,5 mm where the gas can flow so I'm leaking about 4% (2x 1/2 of one gap) it's also a replication of the improved turbine patant ( the one whit Star washers they reach out to about 1/2 of the radius). By the way I would love to see yours running on Steam , you can just use a presure cooker if you have one it's really easy , if you like send mi a email so we maybe can exchange Tel nr so we can elaborate more about this interesting project😁👍
@@oscarverwey my disk spacing is just 0.4mm. I have a small steam cleaner somewhere, might try that, although the temperature might be too high for the carbon fiber reinforced PETG I used. I forgot in which comment you shared your email, but here is mine: nick[at]waveguide.blog
@@Waveguide oke so it could not handle 100 Deg c ? , You May tray to make a fenturi nozzel to pull cold steam (50/60deg c) whit the Air stream into the turbine just to get way more flow en power, also you can use a Paint sprayer whit hot water in it it's makes a crazy amount of volume, I would love to see such a small turbine power a flash light bulb or change a phone or both 🤓
In the “Lesics” video “Tesla Turbine The interesting physics behind it” on RUclips we can see that it is not possible to build a large Tesla turbine because the disks need to be as thin as possible at the edges in order not to introduce turbulence as the fluid leaves the disks. For industrial applications we need a disk size of 2 to 3 meters. This is an engineering impossibility because such a thin large disk can not be made strong enough to withstand the high rpm’s needed to gain high efficiency. This means that only very small Tesla turbines can be made. My question is, would it be possible to use a group/cluster of small Tesla turbines and connect them in a Dyson vacuum cleaner cyclone array kind of fashion to a large pipe so that we then have many small turbines working together as one big one would do?
To be honest, I'm still learning about this topic, so I don't feel qualified to answer that question yet. However, incredible results have already been achieved with turbines much smaller than 3 metres. Also, RPM goes down as size goes up for the same speed at the periphery. Also, Tesla suggested tapered disks, in which case not the whole disk needs to be thin.
Frank Germano and Bill Helton have 1MW 36" rotor Tesla turbines with proven 90+ % efficiency. They use landfill as fuel with the only by product distilled water. The only commercial Tesla turbine company that exists in USA at least I think. I think RUclipsr Tesla Tech also sells steam Tesla turbines. Unfortunately Lesics didn't do enough homework on that video. Personally I think they should remake it with the correct information. Small diameter rotors need to spin very fast to make power as they have little leverage. For example a 28mm rotor is supersonic at 234,000rpm and an 800mm rotor is supersonic periphery at 8,200rpm. I've tested rotors that weigh 9.9 grams and at 100,000rpm you won't be stopping that with your fingers without burning. I've ran 27kg 800mm rotors up to 2000rpm and they run for well over an hour on crap bearings. I've designed and produced a batch of supersonic Tesla turbines that are now in several countries.
Lesics is patently wrong with their claims. You absolutely do NOT need to spin the turbine at extreme RPMs to make an effective working Tesla turbine. Tesla turbines get plenty of torque and power even at low RPMs when you know how to design them correctly.
Tesla himself even doesn’t say you have to spin it fast to make them work effectively. To make a higher efficiency turbine he says to do 3 things. -Increase the fluid speed relative to the discs -increase the surface area -decrease the discs spacing to reduce slip on the discs. It’s simple you don’t need to chase high RPMs also because the higher rpm you go the higher the centrifugal head from the discs spinning the more the incoming fluid flow is prevented from coming in because the pressure gradient across the nozzle decreases. This reduces mass flow rate and reduces power out. You can get a higher efficiency with higher RPMs but it is not the only way and it introduces massive amounts of losses all over. Reduce slip. It’s that simple because allll fluids, liquids or gasses, can be made to flow in highly efficient low Reynolds numbers laminar flow regimes for extremely high turbine isentropic efficiencies.
Nice work, I am glad you trusted Tesla's choices in engineering, excellent video.
Lovely! Especially when you add the RPM numbers together.
Are you able to share the rare drawings, Nick? I'd love to take a look at them of know where I could get them from to study. Thanks, John.
Very good Nick! Perhaps 3D print an adapter to go between the blower and turbine.
Awesome replica!👏👏
Love the details!
Outstanding work well done and love the video and explanation 👍❤️😎😎👌

P.S. Are you still working on the adams motor designs? did you manage to ahieve a COP>1?
Thanks! I am no longer working on the Adams Motor, as several avenues led to dead ends. I did not achieve COP>1 as far as I could tell.
