Nice
How about some biometric forms.

Mostly from prepreg carbon twill robot weaving.
I reckon there are some large radius rigid shaft weaves @dougselsam could get a few MW through

I do see why not? I looked a something similar myself for anode for an ion thruster. I was dreaming magic carpet at the time. That was wind round nails and tried to weave it in to a carpet. More a case of right idea wrong approach. I can see this behind advantageous us for a number of applications. Aerospace and space flight being prime examples.

Nasa current has very small scale hall thrusters. something like the chainmail or biomimetic structure would do the job. You would be talking supersizing current space technology. Maybe interplanetary missions with a large crew? If done right it can act as a heat shield? Store solar energy? Blanket the ship in warmth, by capturing particles from the solar wind.

Added bonus it would be incredible lightweight and strong. A balance of rigidity and flexibility. Which would help out with space debris to a limited extent? I can see the whole skin of the vehicle made from it. Bot printers as they are have come along way. You even had the 3D printed bridges.

Nice vid show the whole process in action.
Huge fan of architecture. Something like this rival even the greatest cathedrals. That in itself is no mean feat. It almost calls for a space dock? Wide scale expansion into many sectors. I wonder where the funky designs for skyscrapers were coming from? now I know. Many thanks! :pray:
got to say the Eden project is a worthy mention. Been in awe of that ever since it was built. To think its inflated cells held up? is amazing in of itself!

Flexible shafts are surprisingly complex products whose behavior is not easily predicted by simple calculations. Recently, Dr. Adam Black, an expert on flexible-shaft design, developed mathematical models that help solve this design challenge. They are used as the foundation of engineering software called Perflexion, which models the behavior of all the wires within the shaft.

Just something else to be considered?

Not quite sure how a toroidal prop translates to Awes of Similar nature?
By design it looks like VAWT?

mit labs have looked at these for drone props?
I wonder what you guys think?

Ha ha were you watching the new fan showdown series on Youtube too?
I submitted a 5 blade remix version

Well It cropped up in my feed? I had made a similar design months back sent it to him heard nothing back? sent the stl file some months back? This cropped up? It just looks like the squashed tube function on Tinkercad? Then rotate the blades to require angles? I sent 8 or 12 blade in some point last year? Found it odd? As mine looks vaguely similar? I feel like a demon possessing the other engineering bod? Find it funny people it looks like people try rob from me? I had no idea if anyone had toyed with this before? I wonder if I could get something for my efforts? Could really use it right now? As I donā€™t know the origins? I wonder if they figure about the source code issue? As every Tinkercad cad file is link to the designer? Glad to of had an impacted if true? He must of made a mint from that stl. File? I wasnā€™t expecting much at all? When I sent my fan in to the fan showdown?
If I did design it and mit got hold of it? Thats a win in my book! Looks valuable enough to investigate? I wonder how Iā€™d get a credit? Most of the source code canā€™t be modified? Due the legal stuff? Its like a big no no! Gdpr? It could be convergence thinking? But who knows at this point? Even 1% would do me? That would be modest royalties? Say the businesses using the design earn a few million? 1% it fairly healthy income for someone like me? It mighty strange it landed in my lap? Went away thought nothing of it? Till today? 10k would get me off the state at a time the support is due to collapse? It was along time back when I sent my stl in?
I know Iā€™m open source? But man need bread & butter? 10k would sort me out for 2 years. If it consistent income? Might be much much longer?

Things I do with my boredom?

It donā€™t occur to me sometimes? I did this as a could I win a prize? I bet that went round discord a few time? Bet hey oh I love fishing the cosmos for answers? Sometimes a few come back? Mine is high solidity. @Rodread funny you mentioned the fan showdown? as been the done that got the T-shirt. So to speak? I can up with what I did due to my interest in esoteric things? The ancients might as well have beaten us all to the punch?

Would be funny to see it as a kite?
But there we go lads life is never simple?

@Freeflying, Your comment is a little difficult to get through. Here is a ChatGPT rewrite that adds the famous Thomas Edison quote, and leaves out some other stuff:

If youā€™re talking about the Sharrow propeller, thatā€™s perhaps from 2009 a similar or identical idea was already patented in 2009, so it canā€™t have been copied from you. Here is some discussion: https://www.reddit.com/r/engineering/comments/10pvyx3/toroidal_propellers_a_noisekilling_game_changer/

One quote:

If youā€™re talking about a reviewer maybe reviewing your idea or something that looks like it, wasnā€™t that the point of sending it in?

Edit: another discussion: https://www.reddit.com/r/AskEngineers/comments/10wmb0e/how_did_we_just_think_of_toroidal_propellers/

One comment:

Fair shout @Windy_Skies!
Definitely convergent thinking on my part!
The point is to throw something out there?
It look like the universe answered?
2009 till now, is a long time not to know?
Much appreciated! Very helpful!
If I know some donā€™t mess with the military? they mess you up!
Great to know I can come to similar conclusion? without the need to look at terms of paper? Wouldnā€™t of known what one was? Till very recently? They do say great minds think a like?

Iā€™m out by a hefty margin? Well done that 2009 team! I concede the world is vast as always! Iā€™ve much learn!

I have to laugh a the striking similarities? Even if was was dream weaving? Best return of ideas? Its often where I learn the most? If ever I was looking for directions? Something like that straightened thing out! Fan showdown a great show!

I wonder what happens to all the design he is sent?
As for awes using toroidal blades? Would it make it more suitable for urban environment?

My fan got featured

Excited

Pretty clean air flow. Well done on the effort!
Another step towards quiet turbines, I suppose?
Any chance of seeing windswept version for Kite turbines?
You even got a good Db.score. I have noticed how tight the airflow was on your design? I wonder with a few tweaks you could get it tighter? For more high density flow? It looked very close to forming a tornado? Not expecting it to Chuck trucks around? But would be amusing to see a kite turbine on the WMD list? If it possible to multiply airflow phenomena? Then maybe a new direction for energy production?
After all you do get rouge waves in the ocean? Tai chi state use the opponents momentum against them. Use the wind to create more wind.
I suspect a boost in efficiency? Somewhere near the theoretical maximum?
If weā€™re currently able to toy with vortices? Then maybe a shift in turbines design Is possible?
Great job @Rodread! A top 20 position is for great a shout! Well done rod!

Considering I mentioned a while back the Magnus effect?
Awes copters?

For what I see on the video the CycloTech comprises motors with adjustable pitch blades that are similar to vertical axis rotors placed on a horizontal axis (example Darrieus VAWT). There is no Magnus effect: lift is provided by the pitched blades, not by a whole cylinder-like shape rotating within a flow.

For Magnus effect to occur, there must be a flow (wind or sea current) on the rotating rotor. The Magnus rotor generates positive lift when the flow and the direction of rotation are well adjusted.

A Magnus rotor, like the Flettner rotor, is driven by a motor which consumes a lot of energy.

There are self-rotating rotors that generate Magnus effect like Savonius-like kites (photo below) on a horizontal axis, or Sharp rotor.

Yep fair doos! When I first look at the cyclocar from cycloTech It looked little like?

Or the

Which didnā€™t seam much different due too the arrangement? So yes see it very different!
It acting more like.
But it more like a rotor wing?

Thing I do when I get disturbed abt. @4am by phone calls? Spiny thing look very similar.
