[@DMonZ1988]

wow, that is fascinating! i noticed you re-uploaded the previous video and original comments were lost. because its even more relevant today i'll just say again that i suspect that the cone would also serve to turn the turbine into the wind, if it were allowed to rotate on the mast. not as necessary as one would think though, and being able to mount it on the side of a building is also a nice advantage. very cool!

[@ThinkingandTinkering]

yeah I made an error in the edit so had to do that - sorry about that - I like the cone as a fin idea - thank you for reposting mate

[@dremaboy777]

This is very awesome Rob. I'm glad the other guy mentioned the bigger cone. I was thinking the same. One more "efficiency" improvement, would be the other idea of having the magnets further out to the rim. This is VERY impressive Rob.

[@ThinkingandTinkering]

magnets further out is a good idea mate - I like it - the I built this one first it was without the cone so I just stuck the magnets on the support wheel - but you are right further out is better and now with the large cone we could do exactly that - cheers

Awesome. Sort of reminds me of the sails on a sailboat -- they can tack upwind at a sharp angle nearly facing the wind and still get propulsion, with the bow similar to the cone on the wind generator...

[@ThinkingandTinkering]

yes it reminded me of that too!

[@rodneyjack3309]

Nice! Kind of ticks all the boxes, doesn't it? Fence post mini windmill. I have had that thought for a long time. Way nicer looking than the monsters we have now.😊 Cheers

[@allenshepard7992]

That is so weird. The shape of the spoon made me assume the angle of wind, or attack, was critical. Learn something every day.

[@ThinkingandTinkering]

I think it works in pretty much the same way as a Turgo turbine with air as the working fluid so the responses would be pretty much the same really

[@user-ds2mi8of5t]

GREAT! The cone probably acts as an airfoil generating low pressure behind the cone, which you can use if true!

Looks like a bucket would make a quick shroud on that Bob, cheers.

[@ThinkingandTinkering]

[@colleenforrest7936]

Just wondering if it's the angle of the cone that determines the angle of usable wind? Is the magic angle 60° (because the turbine likes 30° to the spoons), or is it perpendicular to the slope of the cone?

[@kilokilos]

36' or 108' depending how you look at it. Golden mean , 36', 108', 36' triangle

[@68HC060]

Well, a cone is a 'good start', but you can improve upon it. The cone does not have to spin, though, but if the cone does spin and it is heavy, it'll store energy for later and keep spinning, when the wind isn't as strong; smoothing the electricity output.

[@bobbaird8744]

@@68HC060 Same thought, separate the cone from the spoon rotor to require less energy for rotation. Hold the cone in a fixed position ahead of yet near to the rotor.

[@ThinkingandTinkering]

I don't know - I just guessed the cone size and I think you are spot on with this observation and that is well worth looking into

[@louf7178]

@@68HC060 Would there be much greater friction?

This design of yours is really impressive. I've always been fascinated with wind turbines and the different designs. Would you please consider adding a temporary conical inlet to your turbine just to see how the extra working area will affect the results. Thanx

[@uncledodge9396]

You need to mount this and several others on the outside wall of the workshop, I think this is ideal for permanent placement on a wall in a fixed position.

[@mikeladd5880]

If put back to back with another one set to spin in opposite direction, you could capture the wind in most directions

Yes, and have a flat plastic bridge between the second set and it would pick up the wind in all directions. Rob, you got something to patent there.

I stumbled upon you a couple of days ago. I am entranced. There's someone else kind'a like me out there??? Wow. Have to say that I thoroughly enjoy your laughter and the obvious enjoyment you get from these materialized-ideas. Makes me chuckle out loud but, moreover, the attitude inspires me. How about using the funnels from Darwin's (1817, 1901) to direct the air down onto the cone? The staves from the roof-line turbine (1510) could be used to support the base, just like the you did with the afore mentioned, and the stator could be incorporated, likewise. Oh the possibilities!

[@Matthew-ju3nk]

Nice turbine! And so cheap to make!. One suggestion - when you go outside to do these demonstrations in the wind it would be helpful if you hung a ribbon or rag or something in the field of view so we can get an idea of the wind direction that you are experiencing. Thanks for all the cool content!

[@ThinkingandTinkering]

Hi Robert, why don’t you turn it into a ball , a hollow ball with the spoons up and down and all around like blades to catch the wind from all angles then mount it centrally on a post?

[@ThinkingandTinkering]

intersting - cheers mate

[@stephen150]

This looks as though it would work vertically in a tube, withe a helically veined interior, and a vented cap. Just like that Pod wind turbine. No need for directional control. Thanks for the useful content as usual. 🙏

[@ThinkingandTinkering]

I agree and I think that would be cool

[@geofft3214]

Should work well as a wind wall.👍

[@ThinkingandTinkering]

my thought exactly

[@philipkelleher2853]

Great work Robert. I wonder what kind of energy it would produce directly onto an Alternator, with the cone vertical... this way it would protected from the weather. It could power a water-heater element in a water cylinder, I'd imagine. Something similar, but with helical vanes, has been in the back of my mind to try, one fine day. Any suggestions ? Thanks

[@melodiclodgings8]

Also how about 3d printing the fan blades or straight up creating the entire fan that includes the base as well as the cone if necessary?

[@dremaboy777]

Do it. Make a vid. Make the printable files available to us all. This is something special.

[@ThinkingandTinkering]

I am with Drema Boy - go for it

[@dlfabrications]

Put it on a pivot and give it a tail. The design reminds of a single stage turbo fan. If you could 3D print it or get someone to 3D print it for you, you would get a better balanced fan and greater efficiency. 😀

[@stuartwilliams1790]

brilliant, how would it work in a ventum type stack with the generater mounted bellow the vertical orientated stack

[@renemorel1809]

What if you apply a venturi cone ahead of it to lncrease speed and efficiency? A thought 👍

[@benmauro1022]

wonderful idea! I'm glad it works under such varying conditions. I'm curious though if you could improve the efficiency even more by putting the cone behind the turbine and putting a bowl in front of it like a pseudo "teardrop" shape. could you get even more energy out of it?

[@nelu587]

Awesome.

[@ThinkingandTinkering]

Thank you! Cheers!

[@sungazer888]

Having a solid sheet of metal like a cone cut in have attached to the base but not to turbine would capture the sideways wind and funnel it into the spoons. So all long as there is wind it’s moving.

[@josephowens4654]

Very interesting. Can’t help but see these mounted on a roof ridge like a line of daisies. Pitched roof would give an increase in velocity as it’s channeled upward while the downwind pitch gives low pressure suction of wake. A streamlined ‘flower stalk’ mast could be mounted to the tip of the cone to allow rotation into prevailing wind with cone providing stabilisation. Effect of mast turbulence should be minimal given robustness of design.

[@HealthThroughNutrition]

That's quite interesting.

[@ThinkingandTinkering]

cheers mate

[@robertchristensen5251]

I was thinking you could put some 1 inch fins up the cone to help with the running at the 180 degrees. So they funnel the wind to the spoons normally, but utilize the wind themselves at the 180 degree, and maybe have them at a 45 degree angle so they don’t cause much resistance.

[@kieron88ward]

Love it and a cheap recycled project, thinking if making my own. Would it be help if the cone was fixed, rather than rotating (to reduce mass) and with fences along the length of the cone to encourage a more laminar flow?

[@richardblakely1296]

A vertical placement, as for example on top of the roof of a house, and with the generator below, is possible. This vertical positioning would need to vary only slightly from vertical to catch the power of the wind. Also, since the cone would not need to be a full cone, but instead a dome shape, it could be as large as the roof of the house. The house could have a flat roof below the windmill. In the case of a very large version, it could be a mile across, for example, and the area below could be community.

[@stubluesjhb1]

That makes mounting easier, set to prevailing wind

[@ThinkingandTinkering]

for sure

[@l0I0I0I0]

You could easily sell an ideal spoon 🥄 blade for the turbine and they would sell.

Called pressure mediation, this is exactly what the horizontal turbine with cones in the middle does. Wind from any direction turns it.

yes it is - very similar to the waters turbine in fact

[@stevetobias4890]

@@ThinkingandTinkering after I left my original comment, the more I thought about it I realised it would add less efficiency than it would be worth the extra effort and cost. Sometimes the simplicity is worth much more than over complications.

[@morlanius]

The major issue with wind turbines isn't getting it moving (all that mass in the middle wont be helping) its getting it to stop or not letting it go too fast. Commercial wind turbines have the breaks on so much of the time because the wind can't be too low or too high. This still doesn't have as much lifting area as a commercial one.

[@AndyThompson1606]

2 other thoughts - is there enough torque to turn a disc of magnets to harvest heat through induction? And what about a vertical axis version mounted in a shroud with a 360 degree wind diverter at the top?

[@Flashahol]

I suspected that wind direction would not be super critical, but this is impressive. Would be perfect on my balcony.

What's the optimum angle of the spoons?

[@3dpchiron709]

Might it work in 180 degree wind if the cone surface undulated, sort of like the form of an impeller? Could probably 3d print it.

[@ile84]

Would like to see that "ducter" on this one too and how it performs in indirect wind, although one could put rotating leg on a ducted wind turbine and it would most likely turn always towards a wind, because of that "sail" effect of such duct.

[@ThinkingandTinkering]

yes it would

[@melonmusk7502]

Can this dude build a functioning wind turbine for once

[@scotttovey]

If you mount that with it facing 60 degrees up, it will spin when it rains as well. Mounting it on the side of a building that has a steady downdraft, looks like a promising place for it. But I wonder how that would work on the inside corner of two walls of a building where little dust devils are often formed. I don't know what made me think of the dust devils. The memory just popped into my head.

[@68HC060]

Hmm, at first it might sound like a silly idea, but I think it's brilliant. Face it towards the sky always. Put a large funnel above it and let the wind hit the funnel to turn the turbine. The funnel will collect water when raining and also produce electricity.

[@dr.dolphi8915]

just found this list of videos and ate them up 😄. then i had a what if moment.. what if the dunce hat (albeit a bit more difficult to make) was made with glued on elongated triangles, allowing wind to catch the 90 degree angle, but not the (approximate) 30 degree angle as much. when the turbine is at an angle this add on should hereby be increasing the angles of effeciency, and not coming to a complete stop at roughly 90+ degrees, since we now have a built in "vertical axis wind turbine" for wall mount, it might be perfect. ( sorry i dont know all the correct words, i am Danish 😄, thank you for great content)

[@jasonhaymanonthedrawingboard]

I might be going all gooey in the head? I find it interesting, how its similar to the depiction on Egyptian temple. Of the great atum. Definitely think that your on to something. 10v, With the large angular sweep area. Could it be increased by cone size/ shape? Be that parabolic cone, a dome, or moulded geometries? Much like finials of various descriptions. 120’ is pretty good. Would be cool to see the full 360’. Strictly speaking the cone only needs to deflect airflow. so a concrete cone with all the gubbing in would do the job 80m in the air. On the larger scale verity. A very curious discovery. Much like the rose turbine. You did an excellent job.

[@colleenforrest7936]

This system as a wind wall would be interesting. A similar turbine as big as the wind wall may be more efficient, but would it be as easy to make? For a home build, I think it would be easier to make a bunch of small turbines and hook them up than to make a large turbine set up.

[@desertdan100]

As a mechanic and HVAC guy , I know why this is working so well. I have debated engineers about many subjects. I had a deep discussion with one for hours about this same thing. I have been into alternative energy for years and am an Amateur inventer. I have always been a proponent of upgrading things I saw wrong with wind turbine designs. I grew up on a farm and studied the old wind mills in our area in the Midwestern US. I understand a lot about wind. Later I learned a lot about the Venturi effect in mechanical systems and psi changes in different mediums. That cone is helping to compress and speed up the air molecules as well as spin them in a vortex effect. TESLA understood and tried to teach people these concepts. Growing up in Tornado Alley gives me an intimate knowledge of VORTEX effects on the environment around us. I would like to know the exact angle of your cone so I can duplicate and experiment with it in my area. Our winds vary from 5 miles up to 60 mph sustained with gusting and turbulence. We can experience 300 mph straight line micro burst down draft winds. It can tear apart wind turbines that can't turn them selves away from the wind quickly.

[@OpenSourceLowTech]

Yes the cone is creating a vortex that funnels the wind to it in off wind conditions. But I wonder if a "collar"around the vanes would increase the effiency. Don't know. Could we try it.

[@markyaccarino]

[@hippie-io7225]

[@jamesross1003]

OK, I was thinking on a similar design to make a turbine that has 180 degree operational zone. Due to fluid dynamics a bowl shape in the center rather than the cone should work as air/liquids will follow a curved surface. You would lose some efficiency but with the wider gain of functionality might make up for the efficiency losses. Think of it like a sunflower. A sunflower has a curved center face. When the wind hits it, the wind flows across that curved surface(it also has micro wind breaks which you do not want, small protrusions) and then exits through gaps close to the head. The outer petals are shaped to allow for this. It is why such a large and heavy flower head can survive in high winds. In your set up with a bowl rather than the cone would place your spoons at the point that the wind would exit the curvature of the bowl. This is basically the air intake shape roughly of a jet engine if you start with a point and then curve it bowl shaped for the center rather than a straight edged cone. That is why your design is so efficient. I should think that a basic half sphere(bowl shape) would work. Not as efficient but more forgiving as to wind direction.

[@jamesross1003]

The reason I am considering this kind of design is because 2 of these back to back on the same axle would spin regardless of wind direction without need to change the position of the turbine. The spheres could even be in a fixed position with a rotating turbine(spoon arrangement on an axel) in the center making it much more sturdy.

[@colleenforrest7936]

Wouldn't the coanda effect want to pull the center ball towards the wind? I wonder if that reverse pressure could be used to eek out some extra power with the central ball setup? Micro power maybe, but why leave anything on the table?

[@jamesross1003]

@@colleenforrest7936 That is the whole idea. The low pressure opposite the wind side would draw even more air across the blades. Like lift with an airplane wing. More Bernoulli effect than just coanda(coanda for direction and Bernoulli effect to use the low pressure bubble for air speed as the air tries to fill the low pressure bubble), but you get the idea. Faster moving air to the nonwind side as it exits the device.

[@jamesross1003]

@@colleenforrest7936 Think of it this way, the sphere is anchored so it can't move. Something has to give so it is the wind it does so rushing in to fill the void that the "ball" would otherwise want to move into. That is the whole idea behind this theoretical device.
