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 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....

To produce those spirals, a living thing's cells need to be able to produce a consistent angles of an irrational rotation.

@@annaclarafenyo8185 another trick to get some money from investors who have no clue what they are looking at. I can bet that turbine can not even get close to the efficiency of a medieval windmill,not to mention modern eolics......Why i claim this? Because it have a huge drag and friction with very little active surface . Some people don't realise that a turbine is moved by the inertia of the mass of the air passing thru it. Reason why the eolics have only 3 blades with a lot of space between,having more blades would just swirl the air and increase the drag and the mass of the turbine,lowering efficiency.

[@duudsuufd]

@@annaclarafenyo8185 True. They can't brake them in destructive winds. The traditional blades can turn on their axes to capture less wind.

[@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.

Ignoring efficiency of scale & costs of complexity, adjacency interactions impeding ambient airflow etc., aren't you?

[@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.

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.

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.

145% efficiency! that's astounding. I'll take 69% of one.

[@hiltonian_1260]

There’s a number called the Betz Limit. It’s the maximum theoretical efficiency of any device extracting energy from moving air. That number is 59.3%. No actual physical turbine achieves this. At best, they get 80% of that, or 47% efficiency. When you look up the actual numbers on whirligig turbines like this one the efficiency is below that. There’s a reason that all commercial wind turbines look the same; three bladed, horizontal axis, slender blades, upwind. It’s not lack of imagination. Designers have tried thousands of designs over the past 60 years and that’s what works best. Please ignore the whirligig makers and their “ancient knowledge” grift.

[@bryanoneill5047]

I finally understand the Fibonucci set, thankyou, great video.

[@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.

[@zeitgeist785]

Didn’t bother watching the video - seeing efficiency of greater than 100% told me all I needed about the credibility of the information.

[@michaelvanallen6400]

*All practical tests show that small wind turbines hardly generate any electricity! And only at very high costs!* Because there is hardly any wind close to the ground. But 100% more wind generates 800% more electricity! Wind close to ground is also extremely gusty, which usually shortens the service life. Only if you need to be self-sufficient from the power grid, you should erect the largest possible wind turbine on a high mast. With solar modules, on the other hand, you can reliably generate green electricity for 25 years at approx. 3-10 cent/kWh!

[@semaJ455]

Interesting. In my opinion, you explain things in a clear and engaging manner.

[@michaelbuckers]

Modern 3-bladed turbines are already more than 80% efficient. Using more blades you can get marginally more efficiency, at the cost of an extra blade - which is not a small amount. 3 blades is just about the perfect balance between extracting as much of wind power as possible and the lifetime cost of the turbine. Also any efficiency gains at slow water speeds mean absolutely nothing because slow moving water hardly contains any extractable power to begin with, the turbine cost will eclipse its lifetime electricity production value.

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. The Fibonacci spiral is very aggressive compared to that of a conch.

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.

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.

Of course, the turbines that have a vertical axis fix this by putting all the most wearing parts at ground level.

[@bigfishoutofwater3135]

This concept seems promising but feels like an early iteration. There's too much surface at the outer edge which moves the fastest which is why I suspect it didn't do as well at higher speed. Wind turbines use 3 blades because that the smallest number that still balance forces that would wear them out. I wonder if a single bladed turbine in a spiral shape could be made to be perfectly balanced. That would need a lot of precision.

[@JohnDir-xw3hf]

Why overcomplicate and over engineere? 🤦🏼

[@dennisbecraft1303]

​​@@JohnDir-xw3hfThat's not complex or overengineered if it reduces to a single spiral and results in even a few percent increase in efficiency from now on. I see it as comparable to winglets, slats, washout & vortex generators on airplane wings.

[@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?

[@tim40gabby25]

Have a look at rotating spiral flagella - nature suggests this must be efficient, though possibly only at small scale. Add those bumps on whale flippers for good measure.

For craps sakes! It's done for the messed up KZbin algorithms, if thumbnails don't create some sort of hyperbole or drama then the videos are seen less. It's a controversy, but it does indicate the psychological makeup of human beings. Because the data shows people click on drama over accurate information & since KZbin makes its money on clicks the algorithm demands drama in the thumbnails. The creator is forced to play this algorithm game in order just to compete & stay online. So stop getting upset with the creators it's KZbin choosing to create this dramatic overkill of how videos are displayed.

[@Inertia888]

My mind is already trying to find the least expensive way of doing this. First, I will plot various wind speeds in the area where I am able to set up a small wind turbine. Next, I think I will have to decide which plastic material to use. I don't think I will use 3D printing. I think ordering a small stack of appropriately sized sheets of my chosen material will do. Then, I will need to measure out the correct shape, and cut each sheet to size. Mounting each fin on a central axis will be the hardest part, I am guessing. Don't know how I'll do that yet. But it sounds like a fun, and (not prohibitively) expensive project to get into.

What is the length of the blades? Does it have ratio in them too?

[@Swenthorian]

Could this be applied to propeller planes as well?

[@Knyex]

The reason Phi is seen so often in plants is simply because it's irrational, there's no mysticism there Many plants with spiral configurations follow different numbers for their spirals and some like mint forego the spiral configuration entirely and just grow leaves at a 90° angle. And the reason phi specifically seems to be so much more common than other irrational numbers is because it's the "most irrational" number, as in the hardest number to approximate using rational values.

[@Inertia888]

well… that just sounds irrational to me 😜

Extra benefit= Birds less likely to be hit by those turbines.

[@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.

no efficiency improvement can compensate for small wind capturing area. what is the cost of material per unit of gained power?

[@beyondfossil]

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.

@@tzenophile there has been a stigma on ‘alternative’ energy generation for these past decades, driven by marketing FUD, scalability, poorly designed systems, etc…but if the price of these small systems can compete with Solar’s major price declines then the opportunity to use both types makes sense.

@@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.
