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 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.

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.

Very true. It is all about the economies of scale to drive down per-unit cost. Politicians could learn a thing or two about this when trying to acquire defense assets.

But you have NIMBYs like the New England spending years and money preventing such projects

Fascinating discussion on the evolution of wind turbines.

Very challenging, but we must try our best, because the Earth's CO2 and the pollution are on the catastrophic path. But: Solar power in the center of the Sahara is and could not be productive, we already know that, but maybe in 10 or 20 years who know, we must keep trying... Deep water wind turbines also very challenging - high maintenance costs, higher rust, high power losses due to bigger distance from consumers, but we must keep trying ... Tidal turbines/dams, the same. Nuclear power, very challenging. Fossil fuel very polluting. But we have to keep trying our best!

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.

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.

This is amazing.

mare, while your concern is understandable current sources pertaining to the energy generation (coal, petroleum, solar, etc.) are also generally not located within close proximities to the consumer and therefore the distribution relies on significant wire runs to the grid as will the off shore wind turbines. The remote locations will incur more disapportionate costs like the existing more remote sources.

Even floating wind turbines are obsolete, intermittent and expensive in installation/maintenance. Tar Kovacs Systems offshore self-contained plants are exploiting three or four ocean simultaneous power sources without installation work, very low maintenance, producing CONSTANT power or Green Hydrogen, and is increasing/controling each in any weather conditions. No water depth consideration. 100 to 600MW per unit 24/7/365 every where on the oceans.

This has actually been extensively researched and written about in professional spaces and it its actually pretty negligible considering that construction, placement and maintenance are really the only times it creates emissions, and they often go 25 years without needing much maintenance at all, on average they emit between 5 and 25 grams of carbon when coal and natural gas would produce from 100 grams to 870 for the same amount of energy, averaged over the lifetime of the turbines. Everything costs something and when it's a choice between continuing use of fossil fuels (which'll run out eventually and destabilize the climate we rely on for the ability to breathe and eat and whatnot long before that), or we do something to avoid mass suffering in the future when we can before it gets worse, I'd rather take the latter, but maybe that's just me.

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?

Higher wind speeds the taller they build them was the reason they gave I think. But yeah, I get what your saying.
