I have been studying floating cities of the future for years , at first I was considering wind power in my designs for about 4% of the energy mix , but I found I could reduce electrical consumption by about 5% during the day and 7.5% during the night just by underrunning LED lighting (using 4 LED's to do the job of one) and going to superconducting electrical trunk lines.

In 2012, ARPA-e gave an award to Advanced Magnetics Lab for its 10 MW direct drive superconducting nacelle that only weighed 150 tons and was less than 15' tall. This nacelle, combined with a lattice frame tower and a two piece blade 90 m long would be optimal for logistics and should be deployed all up and down Highway 25, five rows deep on both sides of the road. Once the superconducting tech, tower and blades have matured, only then should they be deployed offshore where to O&M would be outrageous for an evolving tech.

The fact they do not use guide wires is confusing to me. The amount of force on that one pole. The wind catching those blades has to put hundreds of tons of horizontal force against the poles. The pole doesn’t simply hold the turbines up in the air, they also have to stop them from blowing over. If guide wires are used they would probably allow for the pole to be made smaller and cheaper. The only problem I see is the guide wires would have to be fairly low on the pole so the blades didn’t hit them. I’m sure even wires halfway up the pole is better than none at all.

Airships make more sense to me for transporting bigger and bigger turbine blades, rather than 3D printing. It seems like the perfect solution. Turbine blades are constructed as lightly as possible and with airships size is no longer a constraint. Plus airships is one of the cheapest modes of transport. The only downside is weather sensitivity and that it's comparatively slow. But when a trip that needs a year of planning is the alternative, those downsides hardly seem to matter.

As a wind technician for 4 years for Vestas, I've led many main component teams and commissioning projects of many turbines. Our site here in Indiana has 329 turbines with two more phase build outs in the planning. As the site QSE and TapRoot certified accident investigator, I've had my fair share of accident investigations. The problem with the critical turbine failures of towers collapsing that happen across the induatry boils down to the particular construction company/crews erecting them. Massive bolt connections on massive tower flanges with massive hydraulic torque equipment that all has to be done by 3-5 man teams per tower cause issuestl that lead to the same mistakes any industry face: complacency, lack of care from being tired, or ignorance. The main component failures such as blades, main bearings, gearboxes, and generators of most often the cause of QC issues from respective manufacturers. It is rare to find serial defects but it does happen. I've personally been involved with a massive blade repair project and gear box replacement project due to serial defect.

The myriad turbine is a cool idea to make a turbine with smaller parts, but I see a few flaws with the design, especially in northern weather conditions… First off, the pipe frame holding the turbines is extremely prone to birds building their nests on it. It’s an issue because they often get hit by the blades when they fly off… This is a problem that early wind turbines that used similar structures for their pole encountered. The turbine frame is also extremely likely to accumulate ice in winter, which would make the whole tower suffer a lot more stress than it might have been initially designed for not only because of the weight of the ice, but also because of the higher wind drag with the ice acting sort of like a sail. Finally, having multiple turbines this close to one another in front of such a structure is extremely likely to create turbulence between the blades, which would make a lot of noise. This is quite undesirable for a wind turbine installed close to people’s houses like they showed in one of their graphics. Maybe they accounted for all of those things and the idea is interesting, but we definitely need to keep those challenges in mind.

Good stuff Matt! I'm a wind turbine engineer and that title is perhaps a bit clickbaity. Advancements in the industry are rarely sexy or revolutionary. Large diameter 3-blade HAWTs are pretty well established to be optimal right now, and improvements tend to be incremental material or manufacturing tweaks. Cost pressure means blades are anything but high tech. They're still mostly cheap fiberglass and balsa wood/foam. Carbon is rarely even worth the cost despite being well established and having superior properties, neverminded things like additive manufacturing or Myriad's crazy design. Keystone Towers is probably the most exciting new tech in the (onshore) industry right now. Reliability is a chronically underappreciated metric in may engineering disciplines. Investors just care about ROI, and LCOE is taken as THE metric to reduce in the wind industry. Risk reduction is harder to quantify and optimize and sell to wind farm owner/operators . With so much price pressure and competition, problems with cheaper model turbines were bound to happen. Rock bottom prices mean balancing on the edge of barely good enough to stay together. Maybe that's not a bad thing. If you can save 2% on cost but 1% of turbines will have a defect causing it to catastrophically fail, you still come out ahead, and doesn't mean we need to rethink anything.

As a Wind Technician I cant imagine the headache of maintaining the Myriad multi rotor design. Just imagine maintaining your car if instead of having one engine and transmission, it had ten... Every bearing needs grease, every gearbox needs oil. From a practical human perspective I don't see it working out. Technicians complain about ergonomics between working on Vestas and GE towers. I hope they test it out for 2-4 years before trying a utility scale project.

Theoretically each smaller unit could be easier individually to work on, like a bunch of go-karts vs a car/truck/semi (depending on scaling factor) you might have to work on 20x more things but those things would each be easier to work on, Plus you can potentially bring only a few bades offline for maintenance instead of the whole turbine (depending on what your doing) meaning you can potentially schedule maintenance more frequently as the opportunity cost for doing so would be lower. Additionally because your working on seperate things you could have more people/crews on 1 spread over the smaller individual units to speed things up.

That is not to say that further innovation is not desirable or warranted. But neither is it true that current technology is not mature and cannot continue to be deployed at scale or that we ought to wait until some new technology fixes current issues.

@@traybern A bunch of wind turbines next to each other, some spinning, some not. That's not due to wind not constantly blowing. The most likely actual reason is because of the energy storage issue. If the turbines are generating more energy than the grid can handle they have to turn off the turbines to avoid overloading the grid. Ideally we'd store the extra energy to be used when the wind isn't blowing but grid storage solutions are just starting to take off. Of course even once we have storage solutions it would still be possible to be generating more power than we need (storage full) or can transfer (the power lines can only handle so much current so even if we needed more power elsewhere, if the lines weren't sufficient we'd still have to shut down the turbines and use a different power source closer to the load).

That was a mistake compared to using solar. However, I would like to reiterate that centralized production of electricity is only of benefit to the large power companies, not to individuals.

Insightful, ty

These industrial and provider-scale solutions seem to be running into a similar type of problem set to what we're seeing with reactors - intensive reliance on bespoke manufacturing, extreme cost outlay and capital requirement and seemingly much higher risk if the device fails (years to fix, same problems building and shipping parts, etc.). The multi-rotor thing looks more viable, albeit much uglier. Personally I'm more interested in small to medium sized units which require less capital outlay and will probably become more popular with small communities or individuals in windy areas. The closer we can get to automation and standardised parts with factory line production the better, SMRs are expected to utilise the same cost savings to raise their viability. With the Boomers retiring capital availability is going to see a sharp decline so smaller means not just "better" but I think will also mean "possible at all" now; perhaps a variation on that large multi-blade thing where it can be expanded and added to over time? Where you can add more turbines as demand grows?

For solar, the output scales linear in the area and the only difference between utility scale roof top and home installations are economy of scale for parts. Wind turbines on the other hand scale with the area covered by the rotor, meaning that increasing the length of the rotor by 20% will roughly result in 40% more potential energy to be harvested. This is limited on land by limits on the sound emissions, but even when restricting the speed of the tip of the rotors, the added size helps to shift the wind profile toward lower speeds. The vertical turbine designs at this point are mostly toys and far from mattering in the real world.

Of all the things you featured in the video, the Myriad system is the most promising and practical. All those on-site manufacturing methods are very early stage and are unlikely to have any real impact in the next 10 years. It's is VERY hard to manufacture in uncontrolled environments like you would find at wind sites. Desert, mountains, ocean - all are radically different and all have an effect on the machines and materials. This is one of the issues 3D home printing companies are facing as well. When it's 35º on one homesite and 105º on another, your materials just don't behave the same way and you have to make adjustments which introduces uncertainty in the final product. The same is 100% true for on-site wind component manufacturing. The one place you don't want uncertainty is in wind generator components - as Siemens has learned.

Thanks again for your wonderful and educational content!

I feel like for areas with decent to good sun, what should be built are very large sand batteries that are heated both directly and indirectly by the sun. A rough concept: You have an outer borosilicate or ceramic glass structure and inside you have a metal structure (preferably Al) that holds the sand or what not. You paint the inside metal structure ultra black on the outside and paint the top of the sand ultra black. You pull a vacuum on the enclosed structure. You also have some Solar panel arrays that are directly connected to resistive heating wires that wrap around the copper tubing that coils in the center of the sand (no need of batteries, controllers, etc just direct current to the resistive wire system). Also point some solar reflectors at the tank. So the inside metal tank is heated both directly by the sun and indirectly by Solar panels--with the copper tubing being heated directly by the Solar panels. The combination of the vacuum insulation and sheer thermal mass will ensure that once up to temp, it will remain more or less constant, even over night, through cloudy days, etc. It will take awhile to get up to working temp, but once there, it should be relatively stabilized. At night time, cover it with an IR reflector to help with this process (or coat it with specialized coating to do the same thing). Anyways, once it is up to working temp, run water through the copper tubing to generate steam to power generators. It is very low maintenance, low complexity, relatively low cost. Though the large borosilicate glass dome might be a challenge and be fairly expensive (and somewhat fragile). The generators would be the only moving parts, but easy to get to and work on if/when needed (unlike the generators in a giant wind turbine).

And that is why one does not throw out the quality control teams.

I'd like to see things go smaller and more localized. Things can be more cost effective and stable, IMO. We see that happening with SMRs and there have been other videos looking at other wind generators that are smaller and may be more residential intended.

The keys are Portability- 20' shipping containers Containers are also the battery banks and control circuits Simplicity- simple fasteners made for extended reuse and material safety +50% for stability and reliability. Operation- the tower head must be capable of being lowered by powered and unpowered systems and power rotated to lock direction, controlled by a aerometer giving wind speeds and direction so the system will automatically feather itself by turning side on to the wind in extreme conditions. Because these turbines aren't huge, they're man replaceable and maintainable without ascending a tower. So like an led taillight, if one goes out, the others keep going. If a fault is detected, the turbine spring brakes would be released to stop all movement until repairs. Think "IKEA" Power Solutions 🤣😂👍 Inexpensive, simple, modular, scalable and for some applications, portable by using the containers as the gravity base😎

For me, the biggest problem of wind power is that they are not that good at a local level, say on your home compared to solar and that might not matter that much for now, but it's a given that as renewable energy gets better and cheaper and battery tech continues to improve, more of us are going to want to generate more of our energy at a local level on our homes and reports are going around that solar is going to be cheaper than all the alternatives, so much so that it become cheaper to not be on the grid any more. The solar industry is already bigger than wind, I suspect over the next decade or so, that gap is going to widen a lot unless the wind industry finds a solution to generate enough energy that's useful without the need for them to be massive and low noise enough that many of us wouldn't have a problem using them on our homes. The advancement of solar is likely going to keep advancing that it could be everywhere and blend into a lot of buildings without impacting the visual makeup, I don't see wind power competing with that in the long run as the advancement of tech continues, most of us are going to want to go gridless so we have full control over the energy we use and what we pay, which will end up more or less being free in the long run.

This exposes a bigger problem with large corporations, the focus on profit over viability. When you chase increasing profits you can lose sight of long term viability of your product. Profits are always short term gains because that is how the economy is designed. They are designing larger windmills because they more efficient in power production for that instant profits, but they are not built to last. It’s cheaper to tear one down and install a new larger model than try and do any major upgrades or long term maintenance. Then you have all that waste from the old windmill that can’t be reused and just goes into landfills. We need to get back to building for longevity not just quick profits.

The size of the HAWT is the desire or marketing of the biggest bang for the buck. Filling the tower with dozens of VAWTs that can add up to close to or the same output. You still get power from VAWTs lower to the ground and lower wind speeds. No issues with rapidly changing directions or high speeds. Any breakdowns, unless it's a tower failure, doesn't result in a complete shutdown. You can just swap the VAWT that's down leaving the rest of the tower still operational.

I’m not one of those people who believes that big wind turbines kills that many birds…but that multi-blade design looks like an absolute avian-shredder!

3d printing in situ seems more prone to these sort of defects than building and transporting. But I guess if they're smaller it doesn't matter as much.

Can you do a write up on what happens to the old turbines and solar panels, where they go etc after their time of use. cheers

really glad this channel exists :)
