I'm building a wood gasifier, and it's driving me crazy watching you build all this cool stuff recently. You all left me back in the wood gas age. 😂😂😂
I've been dreaming of an apocalypse bus that runs on one.....basically the back of the bus would be a tree/telephone pole handler chucking stuff into a chipper and hopper that that feeds the gasification chamber...
@@TheresTyrannyAfoot Very Cool! Cheers!
I have books and plans for them, but just haven’t started yet.
@Cthulhu 🤣 Exactly!
I've seen folks us a compressor system to store wood gas in a propane tank :) It was completely useable even 3 months later, if it was a legit video of course. Now I wonder, could heat energy be used to run an air compressor somehow?
I am really loving this series! Thanks you for posting your explorations.
cheers mate
@@ThinkingandTinkering you could combine screw like rotor, from some of your previous videos, with this but in opposite direction and with different casing that will collect wind from the screw like rotor and transmit to this jet like turbine. So wind goes up the cone not down the cone. And you could put this your Darvin turbine around screw rotor but not all the way just with the point of connection with this jet like turbine and between them you could put real tesla turbine in a way that air that comes out from the tesla turbine get into this jet turbine, so this combination will suck the air even faster from tesla turbine wich will increase torque.
And people think it's easy sticking a video on KZhead 😊 Your efforts are, and always will be, appreciated! 😉👍
yes they do and you are dead right it isn't lol - cheers mate
Thank you Rob. Your enthusiasm and your projects are tremendously inspiring!
wow - cheers mate
It takes a special person with a huge generosity of spirit to share this and to explain so any lay person can grasp the concepts., Thank You Sir.
I like how this guy explains the functionality of everything and goes into detail. Very awesome content on his channel. Thank you.
The cone/rotor piece took me over 2 days to print, but I'm loving following along with this build!
I would just like to say that you are an amazing "nutty professor", I really enjoy watching your vids as they are both extremely informative and totally enjoyable. I truly hope that you find success and solve some of the world's energy problems one day. Thank you.
Your testing methodology makes perfect sense to me. I truly enjoy seeing your experiments and as always, I look forward to seeing where you go with this. Also, as I recently acquired my first 3D printer, I look forward to testing with your designs as well. Thank you for all you do.
Where have you been hiding all my life? So inspiring; such a gifted teacher!
Thank you Robert for explaining who when where why, it doesn't always sink in right away
cheers mate
Torque is directly proportional to current in a DC motor or generator. Voltage means nothing, though you can use it to calculate power when you know the current. To get the current, you must load the generator to make it slow down. There will be a speed under load that gives maximum power. You must apply different loads to see what that is.
A variable resistor may work? And the fan should not be held by hand, it shkuld be fixed in a position to make sure that you have same angle of attack and distance between the fan and the generator.
then you would just be measuring the generator
@@ThinkingandTinkering The only thing you need from a generator is watts. The question is how many can you get at typical wind speed. For that, you can simulate the wind with a blower, but then you must load the generator so that you know how much current it can make at that wind speed, then you can measure the volts at that current and calculate the watts, or connect one of those cheap Ebay watt-meters that give you it directly. When you load a generator, the torque to turn it increases with the current, so it slows down.
I do agree about watts/windspeed being the ultimate measurement. Also it should be in the natural environment and not a laboratory. History also should teach us to stick to AC. One point that I noted about the shape, the vent holes come out where they could affect the wind flow escaping from the tower, if they pointed down, the wind flow would provide more suction. This is another reason to test outdoors.
Love the presentation ... most enjoyable and stimulating.
No one will accuse you of not generating enough talk ! 😀😀 Keep it up
I'm still dreaming haven't turned cog yet. Lol
You can say that again!
lol - I do gas on a bit sometimes lol
I second, third, and fourth-million that statement!
Just measuring the talk alone doesn't tell us everything we need to know. If the starting condition is very windy, then of course we will get much talk. What we need to know is the efficiency of converting that windiness to talk. I believe Robert's performance is optimal.
6:35 That's very interesting because the warmer the generator gets because of the friction the more air it would draw because of the stack effect therefore using the wasted energy as a way to generate more energy. I wonder if enclosing the rotor, at least slightly, would increase efficiency because of the venturi effect.
If you want it to get warmer, paint it black or use black filiment. Need something other than PLA to keep it from melting though. You can also use the PLA as a sort of lost wax casting to make a stronger final product. There's also filiment with a lower melting point.
I may well do mate
Not only that, but I think their decision was also based on avoiding water "collection" towards the bottom of the unit. I think ventum dynamics are onto something "big" - and Robert as well. Ventum is working on a "home" "Ikea style" version - but an open source alternative is always great! :)
@@geoe5621 Yes, when I first started watching the video and the machine was upside down I thought it was just a cool normal project but when I saw that picture showing that it's actually the other way around it instantly triggered my interest. I do believe that even if his or their design doesn't work the concept itself is really future-seeking and things should be developed trying to follow it... Turning air energy which is currently something "temperamental" into something stable and predictable, even if extremely less powerful, would already change the world. Another huge factor is that this type of design doesn't seem to disrupt the enviroment and also wouldn't need the costful maintenance that current turbines do (that's their major deterrent)... Make it work and give them a magnetic bearing and you have the next-gen power plant.
@@ThinkingandTinkering what if you had an outer cylinder, in a material that could absorb heat through sunlight or what have you. Maybe produce a chimney effect to increase flow further.
This is exactly what I mentioned in an earlier video. Im in the process of getting a 3-D printer so I can work on this as we'll and I'll keep you updated. Keep up the good work!
awesome mate
Thank you for making concepts understandable. I love your videos!
I'm enjoying watching this build process develop .. great innovation taking place. These bits can have far reaching positive effects. 👏
bless your heart and cheers mate
The funnel is a nice representation of your mad hatter (crazy good) skills. This has been an awesome evolution of a project. This is something to be truly proud of! Great work!!!
wow cheers mate
I have a rooftop in the city that because of the microclimate and turbulence is subject to sustained extreme high winds. (greater than 100mph, according to roofers) I need to do masonry work every year because the wind scours the brick and mortar away. A turbine for these types of conditions would be very interesting to me.
Imagine if every building could power itself and feed excess back to the grid? We wouldn't need huge projects.
Your system would have to be tougher than a brick! Good luck. Whatever you devised would certainly be quite durable everywhere else! Sounds challenging.
from what you say just about anything would do mate
I have seen horizontal spiral turbines at 6" dia. that looked very impressive. I can't remember the numbers now but there was low coefficient ratio between the turbine and the mounts.
I am absolutely astounded by a youtube video for the first time in a good while
Great project, thanks for sharing! Cheers!
Murray Sir... Ranjith here... Only issue I would like to highlight is that atmospheric air doesn't want to compress without external mechanical component... It would just move over the rotor and take the path of least resistance...
Use pleated or multi layered plastics to increase surface area of blade. High end VAWT systems have “cupping” on one side and vanes on the reverse to use Bernoulli principle
Love what you're doing - some thoughts for improvements 1. If you undercoated and painted the funnel inside surface it could be made smoother and therefore air would flow cleaner. 2. Could you add a hall effect sensor to the shaft that way you could measure rotation and therefore be able to compare rotation and generator output with each change you make. 3. The holes around the funnel base, if these could be made larger (maybe every second one joined) to ensue the used air can excape and not create any back pressure I'm playing with the idea of adding some of these to the roof of my RV to add another source of power to my batteries
I'm currently living off grid in my tiny RV. Currently, it’s parked in the equipment storage yard of the construction company that I work for. Allow me to comment on your proposed modifications... 1. I'm not certain a smooth surface is the best treatment for this situation. It makes sense but consider the effects of the dimples on a golf ball as well as the wind tunnel studies by NASCAR racers in the '60s that brought vinyl tops to the automotive industry. Perhaps some spiral-like veins in the ‘funnel’ area could improve airflow and get it headed in the right direction? 2. This is a great idea at first glance! We would have to consider the potential of the power drag and calculate it into the final equation, but I imagine you already have this in mind... 3. I concur! This was the first thing to come to my mind when near the end of the video Robert Murray-Smith asked viewers for suggestions about improvements. Perhaps fewer vertical supports could be used if designed with the most aerodynamic friendly specs or simply changing the shape of the exhaust ports? I live about 35 miles South of Seattle WA and we don't get as much usable sunshine as other areas so the idea of mini wind powered generators is attractive to me. Maybe several small units could be ganged together for better performance than a single large unit? Some individual units could also be able to continue generating power if one unit was to fail temporarily. I use a ‘SunGoldPower’ brand 3Kw inverter/charger/PV controller without any solar panels up yet. I have two 24-volt 320-watt Renogy solar panels standing by, but I know I’ll need several more to collect the 2.4K watts that I typically use daily. Currently, I have two 24-volt, 100 Ah ‘Chins’ brand lithium batteries that I take down to about 50% daily to maximize their lifespan and I re-charge them to 100% daily. I’m happy with their performance so far. The ‘Chins’ recommended charging rate is limited to 40 amps. I have a Westinghouse dual fuel I use a 3650-watt propane fueled ICE generator with wireless remote control that makes using it during our longer than average winter and wet weather easier than going to start it outside. It takes about 2.5 hours to re-charge the batteries and so far the cost of propane fuel (without road taxes!) has been reasonable.
I appreciate your easy to understand explanations and visual aid to learn. Much better than reading a book for me
Excellent expansion of how to develop & improve anything & your enthusiasm is infectious 😃
cheers mate
I like it, but I had a thought-how about a Vortex swirl design on your funnel to get the air going in the swirling Direction you want it to go in the first place, so as your flaps on the tower direct the air downward the funnel would progressively spiral towards the outlet of the funnel thereby spiraling the air going to the turban, just thinking out loud(PS on the inlet facing slope of the vortex you would want smooth surface and on the trailing facing slope you would want a scruffy finish kind of like orange peels, the scruffy part is to build up air pockets to cushion and redirect the air trying to go in the wrong direction)
All you need to do is feed the first one! That's a "Bernoulli Venturi Stack"! As air flows past each Venturi, they will ALL draw in air on all sides! Same principle as a spray gun! Actually shielding the lower portion of the stack and only directly feeding the first one would surprisingly increase efficiency! Letting the wind hit the entire stack will disrupt the effect! Airflow out the bottom will be more consistent, and directional!
I amnot sure mate but it think they just do that all by themselves
Print one cone then vaccume form the rest over than one
nice one
Just throwing this out for consideration. A functional hat wind generator contest. Headlamp? Marker lights? Radio? It might get some laughs too. All the best!
I love seeing the progress on this, great advice and knowledge as well, cheers!
Glad you enjoyed it!
That's a monster print!
it is big!
This is looking great. Nice job. If I could make a single recommendation it would be to increase your polygon count in tinkercad, so that the polygon edges don't show as clearly on your print surface when finished. Those vertical lines can easily be reduced and it won't make a difference in print time.
Thanks for the tips!
Been following for a while and love this channel, always gets me 🤔
Just got to thinking about those spinners that work by putting candles under them and what others have been saying in the comments... What if instead of gearing it to work on wind coming into it, you paint it black and set it out in the sun and you run it on the hot air coming out? It could probably still use regular wind and rain water too.
there really isn't much energy in that - it would be a whole lot of trouble and expense for very very little return is my real thought on that - but it is just what I think you could always try it and see
Where I live ( central Alberta) I've seen companies testing the "electronics" of dynamic brakes on diesel locomotive by adding more electrical resistance, via a DB unit. I'm wondering if you could add a load to the generator (imput) and measure the amount that it takes slow the speed of the generator. Then using some formula where you substitute in that gathered number to calculate the torque?
do you know what I find mate - it doesn't matter what you do - someone, somewhere at sometime will tell you to do something different - basically you do what you like as long as you get a result that helps you
Thanks
Nice. I like how it's evolving into something vaguely reminiscent of a jet engine.
yes it is - I thought that too!
This is what we are torquing about.😄
Well said mate!
lol - nice one mate
Typically... Volts ~= RPM, Amps ~= torque And Power ~= RPM * Torque..... - Volts * Amps. So instead of reading just unloaded Volts, it would be better measure Amps and Volts. This will require a load, preferable a "matched load".
There are no amps from a rotor, no volts either
@@ThinkingandTinkering What you are testing now is quite fascinating, and am looking forward to it's final form. Sorry, I should have said "In a DC motor or Generator", as I was talking about the volts measurement you were making from the Turbine. Power measurements are even more important for lower speed turbines, as there is little to work with, and every Joule counts.
Great Tanks for charing
well, thank you as always for your growing contribution to new ideas, an even bigger thank you for the proof speech as I have seen my share of problems with this. Cheers :)
Have you given any thought to building a filament extruder? I made one to make pet bottles into filament. It would be really cool to make this turbine from a recycled product! I also had an idea to anneal graphene to the inside of a bottle with a paint roller attached to a motor then cut it into the ribbon which you would then further process into filament. I'd do it myself but I'm going into the hospital for cancer treatment for the next month or two and if I don't make it I'd like to know that at least the idea got out there? May not work but I thought it would be cool to try it! Consider it an old man's make a wish. Lol
Good luck with the treatment Herger.Fingers crossed for you.
Best of luck to you sir. Get better and get to work on building your graphene empire.
I have given some thought to it an I agree making it from recycled components would be good - I have an idea or two about that too - mostly involving old bottle and a heat gun!
Thanks! I don't plan on losing this fight but nobody ever does I suspect. I'm giving it all I got.
What if you add one counter rotating outer ring which is powered by the out blowing wind?
and what else can we do with that outblowing wind? Channel it across more turbines? :D
If we could just make a perpetual motion machine... aye? Faith in technology is always letting us down. Maybe we need a new religion.
@@rickdworsky6457 Usury is perpetual motion device.
sure
One of the pc fan generators from earlier builds over each hole? They are a known quantity. Would particularly blocking the hole change the dynamics of the air in the main machine though
Have always enjoyed your videos. That’s why I subscribed. Also not only do I learn things from these videos. It’s actually selfish sharing that the principles in my mind are correct and jive with yours.
A great experiment! It would be interesting to do a simple wind tunnel type experiment with some smoke to see how the louvres on the wind catcher performs. Whether the air passes by or effectively directed downwards, in which case some vertical baffles could be added to the curvature of the cones? Keep going, can’t wait to see how it develops!
Brilliant - Abolutely Brilliant The world needs more of these types of videos. Understandable, Insightful, and Practical. Thank You
wow - cheers mate
Back in the day we did a project at an aerospace company spending thousands to make a vacuum forming mould to make a mathematically perfect collecting cone as in intake to a small wind tunnel. A few days later walking down the street I passed a pet shop selling large aluminium dog bowls for £3 that were the exact same shape as the bowl that came back from our forming shop ready for finishing.
this happens in all industries, and it sucks when you find that the plastic toy you just bought for 2 bucks for your son contain the part you have spent hours and dollars designing and perfecting
Awesome, I have waited all day to watch and it has been driving me crazy.
lol - sorry mate my bad lol
love the journey!
Love your videos, very interesting and thought provoking.
For many years, sailors have used a wind catcher to funnel air down through a square deck hatch. If you sew a triangular fabric panel with a base width about 2x the hatch opening width, then pull the apex up with a halyard and attach the base corners to two adjacent hatchway corners, you have an efficient catcher for wind which blows over the catcher-attached side of the hatch. If you replicate the panel with another, attach its base to the two opposite corners of the hatchway, the apex to the same halyard, and then sew the two panels together along a vertical line to form an "x" when looking up through the hatchway, then you have a catcher which works fairly well in all directions. A sailmaker could help you shape the panels to encourage efficient vertical airflow.
lovin' this journey.. i gotta print this gem
go for it mate
Awesome stuff! love this build!
cheers mate
So awesome, on the edge of my seat for 1890s
Mr Smith, thanks for your great videos. I can see this Wind Turbine being very useful, if mounted on a traditional weather vane type mount. I don't know how much wind you get from the Heavens, but we get our wind here from Compass direction.
Hi SIr, you could mesurate the output of air from your device by tying a 30L bag for example to the end of the device. Another point, with a so low resistance whell, we could make hot/cold air system around with a funnel of hot air for example coming from the top to cool down inside a tube flowing on the wheel, to make passive thermo-wind turbine. with cooked clay tube with the base sitting on a water bed. Thanks for sharing all this.
Really cool design AND even mre cool explanations! Love your channel.
Very cool stuff, all the efforts are greatly appreciated! Always informative and what I like best, thought provoking =)
nice cheers mate
You had me with "Breaking Wind".
Here's the advantage of the orientation of the thing on Skegness Pier (which I am going to see this year, sometime). The airflow over the top provides a suction to improve or increase the air pressure across the turbine. So you might expect that orientation to perform better than one with the airflow-exit at the bottom.
Many years ago there was an article in a Popular Mechanics a design from the Israelis where a wind tower has many panels around it that open with opposing wind. This put the wind into a vortex and at the bottom was the turbine where air was pulled in from the bottom low pressure side of the vortex. I think I still have the magazine.
Long time listener, first time commenter. I literally just designed and printed the exact same thing 2 days ago! I made mine with 2:1 ratio blade gaps, so it only has 12 blades around. Also my center "spike" is level with the top of the squirrel cage, my "spike" was just a 30deg 0-wall thickness. It creates such solid vacuum pressure at 18v/15A. Im a big fan. Thanks!
nice mate - good job!
Love you Ideas!!! Grate JOB !!!! GO GO GO GO !!!!
“Ground Breaking Wind” it wasn’t the video I was expecting Rob 😂
Thank you for sharing your research. We’re hoping to at least reduce our dependency on grid energy this year and wind generated electricity is likely to play a major role in that as we’re moving to the coast. Keep up the great work. 🙏🏻
Great job Robert. Nice work. You might want to look into the blade pitch. G.E.'s LM-6000 Aeroderivative Gas Turbines have some of the most advanced blade designs. Really enjoy what your doing, and your Fantastic Attitude & Healthy Spirit. Keep your push on Good Sir.
Fantastic video and explaining things, you are a master of your craft. That I know… 😊
Great design Rob. 11:54 It even puts itself together :)
Brilliant 👍, your also very enjoyable to watch. Keep it up!!
a suggestion on the wind capture is to add a screw-type internal parts to create a vortex supply in accordance with the rotation of the actual turbine.
Very nice build, doing this on a larger scale, one could add wind propellers outside each exhaust hole, like the ones used on sailboats. Then one could use the wind a second time to get more energy out of it...
If you turn the entire thing upside down and make the centre piece a dark thermal mass you can create the wind you want yourself even in very low wind conditions as then it becomes a solar updraft tower (which have always been wind turbine, given the crucial factor is wind speed to their function). You can drastically increase the wind speed at relatively low cost by using a variety of regular polished metal mirrors with basic solar trackers on them to track the sun and concentrate it all onto the central thermal mass.
One reason I see for placing the generator section on top of the wind collector is because the wind-redirecting cones are then pointing upward (instead of downward), thus making it more difficult for rainwater to get in and drip on your goodies.
I don't think rain is much of an issue mate
*_I have been watching the evolution of a amazing wind turbine..._* I would love to make 10 or more. I would put on side and face opening towards the wind. A simple tail fin would point it right direction. A series of cross arms would be covered with these turbines. If you had an array of 5 x 5 = 25 turbines in a compact form factor. Several 1 x 6 boards holding turbines. Air has smooth entry, and would exit in back of turbine. Someone could use sheet pf plywood. Cutout 25 holes to house the 25 turbines. That should make some decent volts and amps. A sheet of aluminum would also work well. *_Love the videos... great job .... Cheers... Mate._*
STunning
Good work, fascinating indeed !!
cheers mate
Thanks. I live in an area with low wind speeds so concepts that could lead to usable generation (not looking for large amounts) is interesting. Conventional turbines in my area are pretty much outdoor artwork.
a lot of them are mate lol
Really looking forward to see how the wind funnel works together with the Wind collection how much of a difference it makes👍
me too!
great to learn wind power, thank you
Glad it was helpful!
I can count all the youtubers I look forward to watchin daily on one hand and I'm not including my thumb. You Robert, are number one on that list. Love the approach.
wow - that is very cool mate thanks for telling me that -it is well appreciated
You also want the "exhaust" wind to get sucked out of the bottom side holes of the shroud for more wind speed. And you don't want the wind to blow into those holes either. So you'd want some kind of U-shape around the shroud that can turn freely like a wind vane. Or really any way to create negative air pressure at the bottom, because it will increase your air intake.
cheers mate
Happy Easter Rob. Love your new Easter egg!🥸/Mikael PS. Now I can explane "Y" over the Darwin a half Cocktail-glass for increase the Wind! DS.
nice lol and happy easter to you too mate - cheers
nice work!
Thank you! Cheers!
Great show bruva! I have high hopes for your turbine and generator !
cheers mate
As I did enjoyed the series about the first 1kW wind turbine, I do enjoy this one as well. So, Thank You! :)
awesome - cheers mate
Nice Robert. Keep up the good work!
cheers mate
Really cool, can't wait to see the funnels on there
cheers mate
You should consider adding one way flaps to your shroud, preventing the wind from impeding the diverted downward stream. Flaps on the windward side should be closed and flaps on the leeward side should be open.
Part of the transfer is the impedance matching. The larger input has a lower impedance to air pressure, and translates to a higher impedance to increase the force transfer to the mechanical turbine itself. It's pretty much the opposite of a horn driver in audio systems. There is always an entropy loss in impedance matching, but considering the purpose, it's an excellent design.
Great video.. I have an idea I would like to see you do about making the turbine more efficient. On the stationary cone piece, you could try to put some vanes just before the moving turbine vanes. If you can start to spin the air on the stationary cone so that it exits the cone perpendicular to the moving vanes, I think you may get more thrust. Maybe that wasn't well explained but not sure how else to put it..
For me this project is amazing, not only for what it aims to achieve but also because if i want to make the effort to replicate it on a slightly bigger scale for home production, it is not a conventional wind turbine and i could potentlially "camo" it for something else
nice - cheers mate
thank you, sir. you do not know how near you are with your turbine and wind-tecnic. it is the only thing that needs to be stable in near future. hope you find what you are searching. greetings.
Speed as a Tip Speed Ratio ( the speed on the outer tip of the blade divided by the wind speed) is very useful. Using Hertz readings instead of volts from the alternator the actual RPM can be calculated from the number of magnets in the alternator. Using the RPM and the circumference of the rotor the Tip Speed is calculated. Divide the no load Tip Speed by the wind speed to get the turbines TSR (Tip Speed Ratio). In general the higher the TSR the better the efficiency. Most wind turbines generate the most power when loaded to run at 1/2 the no load TSR.
cheers mate
The shroud test is quite distorted. The shroud reduces the distance between blower and air intake, it simply moves the intake up. From the test it is not clear whether it has any other effect.
I had a friend, now passed, that was looking into making a large-scale version of what you are calling the Water's Generator. I'm pretty sure he got the idea from a book printed in 1976 called Radical Technology. Anyway, I remember telling him that golf balls are shaped the way they are, with all the tiny divots on their surface, in order to let air slip over them more easily. I.E. there is some effect caused by those little divots that reduces drag on the ball. Isuggested he try incorperating the use of those divots on the cone section to allow tbe wind to be traveling faster when the wind meets with the blades. I'm no engineer but thought I may as well tell you the same thing incase there might be something in it. Thanks for all the great videos.
Great videos! With this tech, you can fit a 1 in hole on a 1/2 inch bar. This towers could be done with non high performance materials (steel, or fiberglass instead of carbon fiber) and get the enhanced performance with a smaller turbine, on the ground, instead of having a generator gondola high above, behind the expensive turbines. Just a sugestion for your larger builds, try 3D printing a mold, and then fiberglass parts, say 1/6 of the cone, to be bolted together, the post processing of this sectors should be minimal
Rob... I'm hoping that you will consider adding a 2nd "capture" section that is designed to draw the air out... place that on the backside of your turbine to "pull" the air & distribute it back up in the Windstream (at altitude). Should add to your generation & eliminate the wind dump at ground level. Just tossing in my 2 cents (pence?) for additional improvements. Keep up your awesome work with the channel!
nice one mate and cheers
Loved the idea of tesla wind turbine. A suggestion was made was to put a spiral groove in the cones. Have you plotted/digitized the 3D curve of the coin going down the Cone? I think you might find that there is an exact mathematical curve for that path and you can then print that as the groove of your cone and put in magnetized or electrical wire to see if wind will move faster with boost. suggesting possibilities
I never disliked any program. Because I'm learning. Continually!
