[@maretranquillity]

I would like to see some information on the logistics of getting the electrical power from all of these floating wind generators to the consumers. In the deep water will we run cables on the ocean floor or float them below the surface a few hundred feet down? I imagine that these problems have been studied and addressed but I am interested in seeing the solutions.

[@kylecramer8489]

They're run along the ocean floor like our fiber-optics cables. High voltage cables are really heavy.

[@maretranquillity]

@@kylecramer8489 Thank you, Mr. Cramer, I appreciate your response. Once again the logistics of this process elude me. I am familiar with the cables used to cross the oceans for communications and that they are very expensive. If we are going to put thousands of these windmills in deep water across the oceans we are going to need hundreds of thousands of miles of high voltage cables, since the windmills will be floating the cables will have to be miles long just to reach the floor of the ocean. Unlike communication cables which carry very little weight these high voltage cables will have to carry many tons of weight to support the long distances to the bottom of the ocean. If all the windmills have cables tethered to the ocean floor we will have to have a lot of junction boxes strategically placed to connect the individual windmills to a common cable that goes to land. I see some very difficult problems placing these junction boxes and doing all the connections necessary in water far too deep for divers. I suppose a junction box could be connected to several windmill lines on the deck of a ship and then lowered into place. The ship could then go around to the windmills and attach a cable to each mill. I was sort of hoping that the Bloomberg research people would have references to proposed methods of securing and running the cables that would allow me to read up on the process a bit, but that may be beyond the scope of this program. Thanks again for your quick response.

[@sayed5004]

They will also have a floating substation that will collect power from all the turbines and transmit it onshore through an undersea cable

[@ryccoh]

Why would you float them a few hundred feet down?

[@maretranquillity]

@@sayed5004 Having seen the North Atlantic storms I have to admit that I am skeptical of any kind of large floating system with its parts connected by long, expensive electrical cables. I noted that in the video above the admission that they were planning on the windmills moving around quite a bit since they will not be anchored in any way. If the floating substation is not anchored then the whole farm will be able to slosh around tethered only by the ocean floor cable to land. I think that all of these are solvable problems especially after seeing the natural gas line that has been run from Norway to the UK. The downside to this is that it will take a long time to bring to fruition and it will be EXPENSIVE, thus making the electricity expensive. I'm a big fan of technology but I suspect that we have run out of time where climate change is concerned.

What I would like to see coupled with this is Wave or Tidal power tapping into the energy on or under the surface (Although there are probably engineering problems that would come from adding another complex machine to an already complex machine. Who knows what could come of industrialization and mass production of these things it could become feasible) , and underwater servers for computing. Tie this in with new and old industries on land and not only could you power the world with the energy, but you could build water desalination to end droughts. Coupling this with other mega projects and ideas you could also do things like generate water for Desert Greening in the Sahara or Australia, which would allow for not only more farms but more importantly forestry projects that would capture carbon and provide lumber for more climate friendly construction projects. Add green hydrogen production for fuel in vehicles or used in next generation cargo airships. Technology from this could even be used in off shore farms, freeing up land use. We just need the will to direct capital into these industries and a few people to take the long view.

Same challenges as with tidal power (this has been looked at for over 50 years, there's a reason its not done): (a) Stability and reliability of tethering in the event of very bad weather (b) power cables over such vast distances lose a lot of power, are impractical to implement and also prone to breakage in bad weather, and become very very expensive (lots or copper required). (c) Maintainabliity and repair when things inevitably break. If you want to save the planet, nuclear power is the way.

[@adoatero5129]

Your idea isn't bad, but I'd think the number of adaptable drilling rigs and platforms is pretty small. A bigger problem is that adapting them for wind power production would be so expensive that it probably wouldn't make economical sense. As Henrik Stiesdal says on the video, large scale and big series are the key for cheap production. Oil platforms tend to be different from each other, so you would have to do a lot of tailoring, which is expensive. You'd also have to tailor the maintenance, which would add to the cost too.

[@zetsumeinaito]

Interesting, but what are they gunna do about the sand blasting effects of the ocean salts on the turbines? They'll probably have to replace those blades every 3 to 5 years if they are fiberglass resin composites. Hope they keepin tat in mind and budget.

[@jacklav1]

Capacity factor is not a parameter of wind turbine performance. It equals average power out/ rated power of the machinery (generator and switchgear). You can achieve a very high capacity factor by putting small machines in a large wind turbine. A better measure might be average power/ capital expenditure.

[@zettaiengineer4202]

One utilization model is to colocate data centers(DC) with floating turbines. Generated power would be consumed by the DCs thus no long distance power transmission and there is unlimited cooling water. Intermittent winds could be mitigated by battery storage and/or DCs throttling power draw according to availability. The input and output is data where network connections could be made by terrestrial/satellite radio transmission or running/tapping into fiber optic cables, depending on siting. Note that data connections via Starlink-like satellite constellations will have no adjacent subscribers that compete for bandwidth ie. satellite network capacity is under subscribed over the open ocean.

[@kalpitpjha]

question: looks like the generator is near the top making the center of gravity of this structure high making it easier to 'pitch'(lean backwards) due to wind forces. placing the generator lower and driving it through some sort of drive train would lower the center of gravity, allowing wind to turn the blades (instead of causing the structure to lean backwards) and allow it to capture wind energy more efficiently.. so what is the advantage of placing the generator up high?

[@28russ]

Higher wind speeds the taller they build them was the reason they gave I think. But yeah, I get what your saying. I assume the top can turn so the blades are always facing into the wind, so maybe they can also tilt back and forth a little to counter act the effect and keep the top level and the blades at the right angle of attack to catch the wind efficiently. Not sure though, just a guess 🤷‍♂🙂

[@adityac3239]

You add ballast to the base structure to mitigate

[@kalpitpjha]

that would increase the total weight of the structure. now we need more buoyancy to float. moving existing mass (generator) downwards would probably be more advantageous compared to adding ballast.

[@akyhne]

The people in the video are not building wind turbines. They are building the structures for offshore floating turbines. And since it's in the test phase, they use regular wind turbines. It would be very expensive, just to build special wind turbines for this purpose.

[@NaumRusomarov]

vertical axis wind turbines exist, and they have some advantages compared to horizontal axis wind turbines, although I'm not sure anyone has a large scale commercial turbine of this kind. irl, manufacturers like Siemens and Vestas want as few mechanical moving parts as possible because they are the first thing that breaks in wind turbines. so, adding yet another drive train/gears would probably be a big no-no for them. p.s. check direct drive wind turbines.

[@vipondiu]

As exciting as it is to see wind energy evolve and improve, we have to be realistic. ANY form of energy can power human civilization if scaled enough, even hamsters spinning wheels. We should stop using this sentence for marketing and find the most practical. Global electricity consumption is going to be around 25 PWh soon, so we are going to need 1.8 milion of those 14GWh/y turbines, roughly double it if we cannot find a way to extend its capacity factor (THE big issue since day one). 1,800,000 turbines will require approx 2,160,000,000 tons of material (1,000 for the base as stated in the video, 200 as a favorable assumption for the rest). That's 50% more than total global consumption of steel (30,000 Yamato battleships more or less). If we give them a very optimistic lifespan of 30 years in offshore enviroment, 165 turbines must be replaced every day, forever. That's to match current electricity consumption, where most people in the world consume a fraction of what a first world citizen consumes, and electric transportation is still in its infancy. Ideally we would want 4 or 5 times that (and batteries, gigatons of them). Renewables are awesome until someone picks the pen, paper and calculator and tries to apply them in the scale that we need them. For sure industrialization is going to help and technology will improve. And those numbers are high but not impossible. But if only we apply a fraction of the money and resources to new nuclear energy enterprises...

[@МаксимПокорнюк-е6г]

oil consumption is about 6 billion tons per year. The entire infrastructure for the extraction, processing and transportation of this sea of ​​oil is also millions of tons of steel and concrete. Therefore, 3 billion tons of materials for wind turbines is not so much. The infrastructure for oil refining and production developed throughout the twentieth century, and demanded an incalculable amount of money. Nuclear energy is based on finite resources, they will hardly last for a hundred years. Affordable nuclear fusion energy is a myth.

You can build it for a lot cheaper, so you can build more of them in more areas that make up for it, and you'd have higher total output (during those peaks you fill up hydro storage, be it dams, or everyone talking about new hydrogen tech, or cheap home usage systems, allow people to heat up another 2C during that peak time, or allow people to schedule stuff like washing machines, etc.). Also he was talking about being at max capacity, not not outputting power, looking up danish figures for offshore, their min seems to be about 40% of nameplate capacity for 2018/19, which is one of the worst years in the last decade.

I love this!

The maintenance would be very challenging.

[@kaya051285]

Maybe but they do work. The first offshore wind farm was built in 1991 and decommissioned 2017 so it lasted 26 years and that was first generation offshore wind turbines The current ones are designed to last 30 years but I'd bet they will still be around in 60 years with a big replacement of blades and generator at year 30 allowing another 30 years of operations

[@amangautamjackangle]

@@kaya051285 of course but still maintaining them is labour and technology intensive.

[@kaya051285]

@aman gautam Not as much as you would imagine. In the North Sea using the new 13-15MW turbines that will come online next year is the cheapest source of eletricity in Europe. Cheaper than gas nuclear and solar

[@philebling8855]

How about a sensor to tell the direction of the wind and turn the blades?

[@kaya051285]

The wind turbines do turn to face the wind And the individual blades change their pitch to optimise for a given wind speed The new 15MW turbines coming online in 2024 are very productive

[@junielesparas2063]

How about Tidal turbine for electricity ?
