Could you make some In Depth Study over Magnetic Recirculation of Ions as Thrusters for Dirigibles as the ones from LokeedMartin or Flying Wales. Taking in consideration that Constant Recirculation of Condensed Atmosphere Humidity could generate much more Passive Ions Production from Water Molecular Charge Interactions with Silver Particles. Basically the more Electricity the more Ions, the more Humidity the more Ions, the both of them Recirculation thanks to Magnetic Separation (Iron Nitride) would Build Up Ions which would be Subsequently Accelerated by Electrical Current Generating Even More Active Ions Thrust... It could becoming An Efficient Low Cost Propulsion for Low Atmosphere Commercial/Defensive/Scientific Dirigibles... [I think Plasma Channel Made already a Video upon that...

conventional wind turbines have a lot of drawbacks (noise pollution, threatening endangered species like bald eagles and owls, toxic materials, landfill waste) and are only being implemented successfully in areas that have less severe weather and more wind. An Archimedes (or logarithmic) turbine would be more efficient, last longer, and cause less damage to the environment, It's an idea worth investing in.

The most important metric of a wind turbine is the levelized cost of energy (LCOE). This metric allows you to compare all forms of energy generation in terms of total energy return during the lifetime of operation per investment dollar spent.

[@jensholm5759]

Not at all. You fx also has to add the local climate by temperaure and dirty air, where there are many buildings. That give people a lot of bills, they are not 100% and also needs for expensive beds.

@@jensholm5759 that is all accounted for when calculating LCOE. However, one Interesting thing that LCOE doesn't account for that I am interested in when designing my turbines is the cradle to grave environmental impact of mining, manufacturing, assembling, transporting, installing, operating, and decommissioning each turbine. It's best to keep these in mind during the design phase because ultimately you want to minimize the total emissions and negative environmental impacts involved.

[@dunhillsupramk3]

lets for a moment ignore the fact that wind turbines do affect the eco system for birds and other wildlife... most wind turbines do advertise a life span of 25yrs (which is true in a controlled environment) but we're almost at the end of some of these wind turbine government contracts and the true cost comes out, on avg these wind turbines last 1.5yrs- 2yrs on avg before needing to be replaced and the efficiency actually drops to less than 33% within the 1st 3mts of operation (on avg every 8-10mts the blades is replaced).. this is all thanks to the blades deteriorating much faster than expected, you can use the strongest materials known to man and this would still happen.. the other factors is the weather pattern and storms, in the real world when storms hit wind turbines they need to be replaced, even if you can't see the damage there is micro cracks all over the blades and 90% of the time the motor/ generator is damaged.. now if you think burying nuclear waste was a problem well getting rid of the glass fiber blades is a much MUCH bigger problem (in terms of space requirements) and no they don't biodegrade... as a comparison wind energy takes more ppl and more jobs is created than nuclear energy BUT because there is over 100times more ppl required to make the same power so that factor alone makes wind power more expensive than nuclear energy....

The other potential advantage of having both, by having a more consistent energy being generated, you'll need less of a buffer when it comes to how many batteries you need. But we'll have to see, we've heard so many promising ideas for wind power in urban areas but most just don't work that well, but in recent times, we are seeing a lot more creative ideas on the table, so if any of them can generate some meaningful energy, be cheap enough to buy, it could become a game changer.

[@kennethferland5579]

Seems to me that the mountings they are using are sub-optimal, the wishbone bracket should be horizontal with a pair of rotors with opposite spin thus canceling the gyroscopic effect which would inhibit turning into the wind. This pair assembly then sits on a single pivot point where the two wishbones meet (like to back to back 'C' shapes) which is at the same height as the centerline of the spirals, which means far less torque force is needed to rotate it. This could even be expanded to a quad system all pivoting on one point. The reason you need to do this is that the main mast of a wind turbine is costly, so maximizing the amount of air captured by it is critical for cost effective deployments.

[@skyrask1948]

@@dennisbecraft1303 I would guess that having two counter rotating gear linked turbines in parallel with small clearance would increase efficiency thanks to high pressure zone forming in middle creating additional lift in direction of rotations.

@@skyrask1948 Possibly, if it worked something like an augmenter shroud. I'm guessing too, but I was imagining the resulting higher pressure spot wouldn't be ideal because it's asymmetrical, like not having the rotor aimed directly into the wind. Established theory only gets you so far, then you have to test your own hunches empirically. A 15% improvement on a very old drag design is impressive.

[@planterion7969]

I don't know if placing many of these so close is a good idea. In conventional wind turbines a lot of care goes into placing them in a way that minimizes their effect on each other. I'd assume that if you placed two spirals right next to each other, the effect of the air being diverted to the side would be reduced, and the uneven load throughout one cycle would cause more significant material fatigue. Plus, if the rotation of the turbine was hindering it turning to the wind, you could just place the turbine further back, or add fins behind it, like you see in some old-school water pump wind turbines.

If you're into spirals, check out the Japanese martial art Aikido. Many spirals in nature are the natural and stable resolution of dynamic and opposite forces confronting each other. Such as when a high pressure zone hits a low pressure zone and a tornado forms as a result. Aikido forms dynamic spirals by actively receiving their opponents attack. In a sense the Aikidoka is the low pressure zone to their opponent's high pressure zone. A predictable spiral forms and the Aikidoka is trained to almost ride the vortex of the spiral to use the clash as a way to throw or pin their opponent.

Such an interesting video! For the wind turbines, another practical problem for Fibonacci blades is they need to be able to be "feathered" to slow down or completely stop in high winds -- or whenever the turbine operators need to stop the blade rotation. The traditional horizontal blades would just "feather" so they're parallel with the wind so that all wind rotation force ceases. But the Fibonacci blades don't appear to have this capability.

[@JohnThomas-ci9ml]

Being an avid fan of all things Φ, I found your video instructive and fascinating! A question I have is, "How do such turbines fare in really strong winds?", as conventional turbines can feather to prevent damage in such conditions. Other commentators have suggested the 'economics' are paramount considerations but I tend to view things through a resource-based economy lens rather than an imaginary usury-based bankonomic one with the utter nonsense of elastic & daily changing values of bankster currencies. I'd certainly would like to see houses fitted with these Fibonacci turbines to help lighten the load on both the power grid and our environmental footprints though I see no need to actually connect these turbines to the grid.

[@tealkerberus748]

Just don't mount them on the roof of any building that wasn't specifically engineered for them. The vibrations of a wind turbine can shake a building apart over the life of the turbine. Sticking them on a pole in the back yard also makes them much more accessible, because you can lay the pole down when you need to do maintenance or repairs. Of course, the turbines that have a vertical axis fix this by putting all the most wearing parts at ground level.

The aging electrical grids in most developed countries DOES need to be addressed.

[@etle113]

If we look at it, it's basically just a regular turbine with very large blades. Like the classical old farmer wind mill, the large surface is more efficient at low wind speed because it is hit by a larger number of slow air molecules. However, at high wind speed, where the wind is much more powerful, the large surface area acts like a brick wall and pushes most of the air around the turbine, instead of through it, where its energy can be extracted. . Regular wind turbine don't break the air as much, allowing for more power extraction from the high speed air passing through. So it really is a question of choice: Does one wants to efficiently extract a little power, most of the time, from slow moving air or a lot of power from fast moving air, but only when it's windy?

The Pyamid and Golden ratio is actuallly correct when you consider that the Golen ratio was used to approximate Pi via the fbonacci series. It is oft quoted as a graient of 280 cubits to 220 (1760 / 2 / 280) usings 22/7 as Pi which is 55/21 x 6/5 Herodotus quotes a vairation of this using The area of the face being equal to the square of the height using sqrt 8 x 100 cubits = sqrt 80,000 This is a Pyamid with gradient sqrt Phi : 1. The relaitonship between 280 and 100x sqrt 8 is the relationship between the 28 finger cubits, the 20 finger remen diagonal cubit and the 144/7" Greek cane cubit. These scale in the ration sqrt 0.98:1 (effectively 99%), which is exactly the same as the 30 finger sumerian cubits using 21 sides as a downscale factor of sqrt 0.98 Thus 280 remen diagonal royal cubits = 282+ 28 finger cubits. Thus 280 cane cubits = 282+ remen diagonal cubits.

Had to leave a separate comment. This is brilliant. When these discoveries are made hundreds of years ago - why on earth do we stray from them?! Three steps forward - Two steps back.

[@tzenophile]

Because they don't work better when you factor in the total cost/benefit. They must be a lot heavier than a standard turbine covering the same swept area, and as you scale that up to 10-20 MW turbines of today, imagine the inevitably increased mechanical and material challenges. If they were truly better, we would of course use them.

Generating the formula for the nth term of the Fibonacci sequence is a simple enough task for a homework problem after a first lesson in Z-transforms. The Z-transform solution for the Fibonacci recursion relationship generates a polynomial whose roots are those of the algebraic equation 1/x=1+x, whose roots are the golden ratio and its inverse. From that you get that the Fibonacci sequences goes as phi^n + phi^-n with coefficients that depend upon the first two values you feed into the Fibonacci recursion relationship. Hope you have fun doing the above.

[@Spdman401]

That's pretty cool stuff.

[@davidonfim2381]

The whole idea that some plants use that arrangement of leaves to maximize the amount of sunlight they get has never made any sense to me. First off, the number of plants that do that is quite small. Opposite leaves, whorled leaves, alternate leaves on the same plane, and other growth forms (grass-like plants, vines, columnar structures, etc) are VERY common. Second, I don't think there's much of a correlation here- not every plant wants to maximize its exposure to light (think of plants living in the desert) and many of those that don't still have a spiral pattern of leaves/branches (some cacti, aloes, yuccas, things like that). Many of the plants that you'd think would really want to maximize light exposure (understory plants, those living in high latitudes, etc) don't have such spiral patterns (trillium leaves, mayapples, clovers/Oxalis, Claytonia, most peperomias, etc). Third, you literally practically never find these spirals out in nature. Many of the examples people use have been strongly artificially selected. Some of them don't even have anything to do with light exposure (eg. pine cones, sunflower seed heads, or pineapples). Even the plants that, under ideal conditions, grow as those nice little spirals, often don't grow like that in the real world. They are often bent towards one side or another, the spacing between the spirals varies, etc. Fourth, that explanation only really works in a VERY limited set of conditions- light coming directly from above, and plants with leaves that are very close to each other and that can't move. However, the sun moves across the sky so that the light is practically never coming straight from above, plants are practically never oriented perfectly straight up and have many horizontal or diagonal components, the leaves are often not all that close to each other, and individual leaves can also move to face towards the light. No, I don't buy the light explanation for most plants (even many with a spiral pattern of growth). I think the real reasons involve just the fact that developmental processes are iterative and the fact that packing things into spirals is often an efficient way of packing a lot of things in a relatively small space.

[@MatthewSuffidy]

Like you said the ratio is defined by the statement a/b = b/(a+b). Using the quadratic formula that is (sqrt5+1)/2 If that is specifically useful to any physics application or not, maybe. There may be some application for example in reducing product cutting waste. Looking at these propellers, they may be mostly effective in their surface contact to air, and possible complex interaction with the air caused by vacuum forces.

[@dimitri877]

The biggest win for these types of wind generators is that despite lower efficiency they have a broader operating range. A traditional three-bladed wind generator needs clean air to reach peak efficiency and cannot be used under or over a certain threshold. They need to be high up in an open space. Spiral types along with upright models usually only have one limit: speed. There are 'folding' designs out there which tuck in the blades to reduce surface area in order to stay within the 'speed limit', increasing the 'harvesting bandwidth' even more.

[@Hellsong89]

Also thing to note, this design while may be better at lower speeds witch would be really nice in not so windy areas, fails moment you add in the real life problems like snow and ice. From the looks of it, this will just gobble up all the ice into the groove and fill it over time. Depending on the material used, you could use black non sticky material to melt off any ice forming, or use heating coil in the center axis, but like with any other wind turbine this uses energy and defeats the point, not allowing the turbine even spin when enough ice has formed during calm weather. Also due the surface area that would require chinook helicopter to spray enough ethanol to defrost the turbine, instead of smaller helicopter used today to defrost them.

[@AdrieKooijman]

A turbine slowly spinning in low wind still produces hardly any energy. It might look nice but just like solar panels on a cloudy day in December they are practically useless.

Just show how to solve simple constant-coefficient finite linear difference/recursion equations in general. Here: x^3 - 2*x^2 +5*x -1=0 has roots approximately r=0.21676, s=0.89162 + 1.95409*i, t = complex conjugate of s. So x(n+3)=2*x(n+2) -5*x(n+1) + x(n) has in particular one solution x(n)=r^n. In fact, n does not even have to be a nonnegative integer. But, to not go too far off course, assume n=nonnegative integer. Then x(n)=r^n is the solution with x(0)=1, x(1)=r, x(2)=r^2. Notice how r^n -> 0 as n-> + infinity. But, if you want to start with three initial conditions all of which are integers, then x(n)=A*r^n + B*(s^n + t^n) + C*(s^n - t^n) for some constants A, B, C. Or x(n)=A*r^n + 2*B*Re(s^n) + 2*C*Im(s^n)

@@keithnance4209 I would very much like to think so too. Having invested in solar and a battery (which work great) and living in a very windy place it would be wonderful to top up with a wind turbine. But I can't find any serious product (=HAWT) that would seem to recover its cost before breaking down. It would also have to be so big/tall that it would be hard to get a building permit. And with the solar and battery my remaining needs are only 2-3 MWh in the winter months, so the rational thing to do is to buy that from the Big Wind companies nearby.

If you were to take the 3 individual blades, and isolate them, there is another amazing possibility. If they could be placed on a scissor mechanism, much like the mechanical advance weights of an older car distributor, as the speed, or volume of the air increases, they could throw out from the center, to harvest even more wind power as it becomes available. Kind of a variable torque, dictated by available wind.

[@keithwilliams6007]

The kinetic energy / rotating mass of this geometry will not "scale-up" based purely on simple open-flow steady-state flow equations (see Betz's law), however the real concern is the ability to control (known as "feathering") the amount of generated lift & drag (a measure of captured power) in a variety of wind velocities and wind flow (turbulent and laminar) regemes. With a fixed blade geometry, feathering would need to be done by a combination of pre/post diffusers (ducting won't work efficiently at high velocity and low kinematic viscosities (high Reynolds' regimes) and azimuth holding (deliberately "stalling" by generating a large angle-of-attack wrt to the prevalent wind). Any diffusing over the turbine reduces overall efficiency and control (e.g. why there are so few "push-prop" plane designs in production) and azimuth holding mandates sufficient clutching force (mechanical and/or electro-motive) actuators which add a good deal of weight to the system. The final issue to overcome is the "dirty power" (high noise components in the electrical output) which results from vastly different flow regimes (hence high torque variances) across the rotor. This noise must be filtered out (usually by a dedicated application-specific (power grid or local storage) inverter before it can be stored and/or consumed. This electrical noise ends up being "wasted energy capture" that further reduces the overall efficiency of the system. In short, there's really nothing to be gained here. Existing "drag" designs scale-down better and existing "lift" designs scale-up better. This manages to be "good at nothing" with additional control complexities.

[@GregAtlas]

Assuming this is more efficient: There would likely have to be some sort of shroud that could be automatically put around the turbine in order to control the speed or even completely stop flow all together. The standard propeller types can turn their blades to get less wind power in addition to having brakes in the system otherwise high winds can damage them or even rip them apart purely from the centrifugal forces in extreme cases. Having this ability to stop the turbine is also important for maintenance.

All logarithmic spirals grow and shrink based on the same ratio every turn. That is what it means to be logarithmic. It could be that every turn doubles in size, meaning the ratio is 2. It could be that it increases/decreases in size by a ratio of 1.000001. It could be that it increases/decreases in size by a ratio of 9 million. The Fibonacci ratio is just one with very specific properties that relates to anything that is fractal. Nature is full of fractals. Seashells are not fractal and therefor do not need to follow the Fibonacci ratio. Natural spirals like the ones of the seashells has nothing to do with this number. Most of them are not even close.
