Airborne Wind Turbines: The Future of Clean Energy?

Thanks to SurfShark for making this video possible. Go to surfshark.com/... an extra 4 months Surfshark.
Airborne wind energy has been catching my intertest for a few years now, and I thought it was time I looked into it a bit deeper. This video covers a number of developments in the space, including kites, balloons, and drones. A number of great companies have tried and failed, so will it every come to fruition?

Congratulations on submitting your Ph.D. thesis! I know what a relief it is to get to that point and past the, "I'm never going to finish this" stage. The bird safety issue with static wind turbines is rather over stated (often by those who advocate for continued fossil fuel burning). The estimate for wind turbine bird deaths in the USA, with 150GW of installed wind capacity, or 9.8% of the country's total power generation, is between 681,000 and 1.4 million. Not small, but compared to the estimated 1 billion birds killed by buildings and the 1.3 to 4 billion killed by cats (again, just in the USA), the number pales in to insignificance. I'd be the first to advocate for action to reduce those wind turbine deaths (for example, painting one blade of a turbine black, to increase visibility, can reduce bird fatalities by more than 70%), but it's really a distraction. If the USA generated ALL of its power using wind turbines and took no action to increase bird safety, it would be responsible for at most 0.6% of the bird deaths in the country. I'm also ignoring that fossil fuel burning is estimated to kill 24 million birds per year.

[@null-u7e]

I'm pretty sure it's because helium is impossible to contain, so it's requiring bouyancy to keep it flying was the issue. there's no way you can keep the helium from escaping. It'll literally leak out of a solid metal pressure vessel though the metal walls.

[@dosgos]

Modern kite designs are efficient and capture powerful, smooth air from higher altitudes. Launching and tweaking the kite's figure 8's optimally requires visual and hand sense, plus a sense of what the wind is doing. Wind velocity and direction changes, so different kite sizes are used in kitesurfing for optimal performance. Errant gusts would be tough for computers to deal with IMHO but they are less common once a few meters above the water. One needs a big radius to cover all the wind directions and protect from kites crashing to the ground. The kite and cables wear out from variable tension, vibrations, salt, silt, UV light, pollution, etc.

[@jacka9612]

When you covered wind kites that produce electricity, the natural next thing would be to cover Minesto tidal kites that produce electricity cost effectively because of them beeng very lite and small (12m, 28 tonnes, 1,2MW) and able to operate in slow currents which other tidal turbines can't.

Thanks for covering this topic and thanks for the wind turbines in your background shot. Nice touch! lol

[@dianapennepacker6854]

I see these as an amazing solution for. 1) Military. 2) Survival/Remote places. 3) Emeregency workers after a disaster. Being able to produce energy for cheaper in some remote location seems great. Lots of barren places on earth with free sky above! For infrastructure purposes? I sort of doubt it unless these get incredibly big, or fly higher. I mean the whole advantage is to take advantage of high altitude winds right? Yet none of em seem to do it. Nor do generators of any sort seem to be able to handle those high turbulent winds! So even if they could get higher. Could they actually take advantage of it? Dunno. Tidal also has a long way to go. The issue there is simply the cost of installing then more importantly maintaining. The ocean is brutal on equipment. Now that pervoskites and batteries are coming online. Going to be tough for some of the other technologies to get cheap enough to compete. I do hope millimeter wave drilling takes off along with those enclosed loop systems so we aren't spreading toxic shyte already in the ground into the water table.

[@MIA_DaDe]

Some variants have been proven well enough for over a decade even (some of the flying wing or gyrocopters work quite well and are reliable enough to implement), but the main issue is bureaucratic and regulatory. Basically it's hard to get an airspace restriction put in place that isn't temporary due to the flight hazard such systems would pose to any aircraft.

[@winfriedtheis5767]

Congratulations with submitting your thesis!🎉 Great video! As you point out at the end, many things were deemed impossible, turned out to be possible, and in this case these companies have already proven that the principle is feasible. I would see these as another piece in the puzzle.

[@johnlord8337]

The "O" flying air craft is the most-reasonable situation as the wings fly the craft, while the fan inside the turbine, like an aircraft jet turbine, is able to spin at enormous wind velocities (at higher elevations).

[@rogerphelps9939]

That rather restricts the swept area which is bad.

[@johnlord8337]

@@rogerphelps9939 Many of the other tethered airfoil wing designs with the scaffolded wind turbine below the wings is not proper, and removes the aerodynamic lift under the wing of the craft itself.

[@rogerphelps9939]

These airborne systems appear to have rather small swept areas when compared with big ground based turbines. In order to compensate for lack of area you need a much greater wind speed. fortunately a doubling of wind speed compensates for a factor of 8 reduction in the swept area so the maths might actually be in favour of large aerial systems.

[@HaukeLaging]

The regulatory challanges (whatever they may be in detail) are obviously orders os magnitude smaller than with wind turbines in the ground. In Germany there are few locations left where you could (legally) put up a wind turbine because house owners do not want them in their vicinity. Then there is the problem that they kill a lot of birds. So if there are rare, protected birds in an area, that's the end of all plans to put a wind turbine on the ground there. Both problems disappear with airborne wind energy. The next problem is that the good locations (a lot of strong wind) were used first, obviously. So each new (not: replacement) wind turbine is worse than those before. The main challange of the transition to renewable energy is to always have enough energy available. Those who can offer that to a smaller extent will be paid less. A very important advantage of the airborne wind power is that the winds are not only stronger at higher altitudes, they are more reliable, too. In the future most of the solar power will go to some kind of storage (additional cost, less efficient). The airborne wind power can "always" be sold directly and at higher prices. While I am writing this, an interesting question comes to my mind: How close to each other can airborne power elements be put? On the ground you need quite some distance between them due to the effect they have on the wind behind them. But the kites are so small and can fly at different hights that it mighte be possible to let them fly quite close. Making sure they fly in parallel should not be that difficult. And maybe they could even be mechanically connected on the ground so that less generators are needed. That may be something worth talking to the macufacturers about.

[@dosgos]

French brothers Bruno and Dominique Legaignoux invented the efficient kite design in the 1980s. Great potential for niche applications.

[@jonjimihendrix]

Cool idea, but I do see a problem. Obviously, we would need fields of these. In order to avoid tangling two tethers together, they would have to be spaced twice the tethers length apart. At 800m, that’s 1.6km between towers. Meanwhile, that space below its entire circumference must be kept clear and basically unused. Maybe offshore, from a drone boat or something?

[@gregcollins3404]

My idea is to use a spring loaded ratchet mechanism with a flywheel on the ground based generator to pulse the tether. Similar to how a rowing exerciser works. Makes the kite very simple as it doesn't have to fly around in figure eights etc. Just stays up in the air and repetitively yanks on the tether....

[@christophvonwaldhuf]

how does it yank on the tether? What design you have in mind? Wing ? What about spring force being different at different heights?

[@gregcollins3404]

To optimize the function, the spring action would need to be dynamically adjustable, and the kite needs to pulse its pull to resonate with the ratchet spring ...

[@177grego]

As a sport kite flyer I can say definitely that figure eights provide much more pull and are inherently stable

[@toml6505]

I have an idea for an electric flying glider that charges its batteries while in the air when in excess lift/thermals, and or on the ground in sufficiently strong winds! Similar to airborne wind turbines but just has to make enough power for itself to remain airborne with its dual purpose motors/generators.

[@shaunkaufmann6091]

Just a heads up, you missed one crucial aspect of these approaches: they significantly increase the projected area that the kites can sweep out relative to their size (ignoring the balloon one of course). also there is a tidal version of this.

Anyone who has flown kites recognize gusts and wind shifts in only a few feet feet causes the kite to shift, swing, and eventually fall. Even if you get a kite "stable" with a tail, it is never stable day after day, week after week. Eventually the wind gusts, and shift in wind in level, e.g. 20 ft to 40 ft, 40 ft to 60 feet, all effect the kite. You've launching a wind turbine "kite".

Firstly congratulations on submitting thesis and free time. Secondly awesome video and concept Just wondering could they consider using a tube which is shrouded in Kevlar or something with high tensile strength, this can then be used to supply gas to lift and deflate or slowly pump up water to act as ballast to make sail heavier and come down. Even if it had two lite weight tubes one higher in foil the other lower so the lower one for buoyant gas the higher one for denser air, when you need to lower it switch valve so the heavier air coming in at the bottom will displace lite gas which is removed by displacement back down the tube into a reservoir this will represent the cyclic lift and lower of foil. As for water yes I know there would be issues using public supply because the height local pressure wouldn't e high enough but a little pump connected to solar should do it whether it's air or water being pumped they are both fluids. Take care m8, keep being awesome, from some random Kiwi in New Zealand "Kia Kaha" - "Stay Strong".

With the right optimizations each 50 story building could power themselves.

[@feuby8480]

Having fly a kite, I never managed to pilot it with a single wire. I may be stupid,... Wait I'm stupid, but I managed to make awesome figures with a kite which had two wires, one for each side. I could have it go where I wanted and even reel it easily making it go above me. Yes IA can do a lot. But honnestly I kind of feel like any of theses designs could get a lot more control with 2 wires. There may be issues with it (especially wires getting tangled, and maybe rubbing each others (wich could be a no-no), but I think that you could pretty much manage it with a rotating arm on the ground with both cables preventing them to ever tangle, just making the same moves as the kite no matter what. I guess they already though about that but it is kind of strange to see. Especially since it is kinda complex to get a computer controling it. I feel like getting more control easier is better here, so instead of IA, you could rely on scripts.

I fell for this when I was younger. I thought this would be the future of energy. I was also really high on tidal energy. Tidal might well be a supplementary source for certain locations, but I've come to accept that it's almost certainly never going to be a heavy part of our energy mix. High altitude wind though, I am now convinced, is just a scam. I don't mean in the literal sense, but in the sense that this is never going to be a thing that scales. By the time it gets economical, odds are good that fusion will be arriving, and that will blow everything out of the water. I'm not saying that because I think fusion is just around the corner, I'm saying it because I think high altitude wind is a looong way from being economical. I hope they prove me wrong.

Compare the infastructure cost per KwHr, and I would be pretty sure the foundations for any tether system eg mass to restrain a variable (snatching) load would be compable to a traditional wind turbine. Then, there are the cost and durability requirements of the tether. I'm guessing that over a 20+ year system life, this would require multiple replacement cycles along with constant monitoring and maintainence. Now airspace, go to your local winch launching gliding club. A wire going up to 2000+ feet presents a catastrophic air traffic hazard, so any implementation would require a no-fly zone around the total systems 3d area of operation. Food for thought.

Conventional turbines use there whole rotor diameter, those flying wings can't do that even if they try really hard! No mater how good your wind is, you can't make up for the unused wind area of those kites! Even worse, it scales real bad, get the think even higher up, you need even more space to fly it. You would need multiple wings flying coordinated side by side to get the same coverage, and seeing them having trouble with a single wing, I can't imagine having them fly multiple ones 10-30 meters apart from each other! Nore this being any more economical. Conventional turbines are just too low hanging fruits! 🤷

I really love your channel. You're a smart kid, making the right videos.

Why would there be a 10 hour time limit on a kite?

[@noprivacyverner]

they need to fold the sail in before pulling it in again to minimise the power use even more

[@PeanutsDadForever]

Very, interesting! Fingers crossed

If they could get it in to the jet stream and beam it down they would be on to a serious end game solution.

If you want to see multi-kite turbines I make #KiteTurbine A torque to ground transmission solution using tensile networks of kites

Build a bunch of similar ground power systems and have competitions to write the software..

I like this tech but it has to have one of the worst ratios of power vs surface needed. If the cable is 600m long that would be the minimum distance between system for the kites not to get entangled. And then at least twice as much land around it for safety if it falls to the ground. The only way I see a farm of this kites is offshore.
