@@greek9244There is no source of power you can extract from that will not impact our environment. Take large amounts of power from tides and you will absolutely change climate.
He is right we need every type available, Solar are bad in areas near the poles, wind might not be enough too, but Ocean currents are always there. I do believe this tech will have a bright future. Now, where can I buy their stocks.
The density of water is roughly 1000 times greater than air. Also by flying a kite relative to the tidal stream you can achieve a speed up to 10 times greater than the actual stream (7-8 times is more realistic). If you like physics and math you can play around with the power turbine formula which depends on density and velocity cubed (^3): - Density x1000 - Relative velocity cubed x10^3 = x1000 P = 0.5 * ρ * A * Cp * v^3 So for an equal given sweep area and stream velocity for the turbine, Minestos solution could potential generate one million (x1 000 000) times more power than a wind turbine. Hence, the turbine can be so small compared to a wind turbine.
I'm not quite sure I believe that 10x greater velocity number, I understand when it's flying into the water direction the velocity will increase, however for every moment it flies into the stream it must also fly away from the water's direction in order to not move relative to where it is tethered, leaving to a net velocity change of 0. I would also suspect our Cp value will be smaller for water than wind simply because there would be considerably more drag due to the density of water, but I'm not really into hydrodynamics enough to know by how much. But even so you're right, the massive density difference of water allows you to get more with smaller size turbines, however there is a very real limitation of that, in order to get the more power the turbine does need to physically spin faster and there are material stress limitations to that. Now I know you were not suggesting that you could get one million times more power, I just wanted to stop that thought that a single big underwater turbine could provide a million times the power of a land based wind turbine.
I think your comment is misleading at best. Why are you multiplying the velocity by ten? The blades of a wind turbine also do the same crosswind motion, so there is really no difference there. Except that the velocity of the water stream is probably much much smaller than typical wind speeds. Another thing is the drag that is much greater in water and especially bad for these kinds of systems where the tether is dragged through the water. You can even see in the video that they try to minimize this effect by applying this airfoil shape to the tether. But still, since as you said, you want a high cross-stream velocity but this directly increases the drag induced by the tether with the velocity squared. So overall, you can expect ρ to be 1000 times higher, but v and also A to be smaller than for typical wind turbines. And simply assuming v and A to be equal is not realistic.
It’s great we are finally making use of the seas around us - so much potential, but should we not consider using the tides / top of the oceans instead of going below the water / into marine life?
not a expert but I'd imagine they want to find the sweet spot between to deep where its difficult to maintain and upkeep and to far up where the environment constantly changes depending on the weather. I bet they try to aim for some consistent streams.
Great way of harnessing the powers of the ocean! Weather does not interfere as with wave. This is predictable base load that will give stability to the electricity production. With a solution like this the need for expansive storage is much lower. In total it is better than wind farms taking into account the need for storage or the need for oil generators.
Finally! A mooring is far cheaper than a post in the sea floor, and far more versatile, too. There are many good reasons to use kites for wind power, but with water's buoyancy, all the problems vanish, just leaving the benefits.
For those of you who are concerned about the impact on marine life. Marine life is not dumbed-down pieces of meat swimming around without any analysis of their surroundings. Larger animals will avoid the area and small fish will be able to swim through and avoid the power plants. Yes, some animal will certainly get hurt at some point, but all energy types do in some way.
Shame birds aren't as smart as these fish you talk of as they seem to non stop get clapped by wind turbines. These smart fish seem to be pretty dumb when it comes to catching them on pieces of plastic I jiggle.
@@victorlockett816I think you can figure out the difference between a wind turbin and this kite. Minesto's solution will be perceived more as an aquatic animal that swims forward and something that as a fish you will naturally try to avoid. Comparing it to fishing where the very idea is to trick the fish is just stupid. And as I wrote, there will certainly be one or two animals that are harmed, but compared to other things we humans do, it will be marginal.
In addition, it can even have positive effects on animal life as it will not be possible to fish in these particular areas, which gives the fish a safe place to grow strong before it spreads to other areas.
The Faroe Islands are fortunate. The Welsh Government intended to create energy using tidal power off the Welsh coast, but Westminster blocked it and still refuse to devolve energy to Wales.
Don’t worry there will still be time. As soon as the kite is verified by third parties welsh/uk government could fund building a whole park with these kites.
Simec Atlantis energy have been looking at underwater generators.They have an energy park at Uskmouth. Also there have been experiments of a similar nature conducted off the Anglesey coast .
It'll be interesting to see how this goes once installed. 1.2MW is only about 10% the size of big current offshore wind turbines, and it's a rated capacity, not average output? It must be borne in mind that NetZero doesn't just demand electricity is renewable, but also every other energy consumed by an economy. For example UK electricity consumption averages 40GW, but total *energy* consumption averages around 180GW - and that's while someone else manufactures/grows the things we use/eat.
This is predictable energy. When in parks, they will place them so the phases overlap, which gives base load 24/7. They plan for larger dragons used in ocean currents as well. Those never stop.

These look amazing and I wholeheartedly agree that we need to embrace renewables... but what about marine megafauna? Whales already have to contend with submarine noise, entanglement and boat strikes. I hope they've done their impact assessments and plan to place farms accordingly.
They have done lots of research on this and found no problems, the animals just avoid them cuz they are not super fast. They have said that if it becomes a problem they can just add a sensor and shut it off when whales are close
@@Ginflyer I rather stick to my oil/gas stocks and get rich. You will get broke hoping for a fake green energy scam. Then you will regret hyping this trash project.
Drones are currently being looked at by the government & will be regulated so anything like this ok if they are using it but something like this could be made into basically underwater drones just like the ones anyone can buy. How cool would it be to get a view of everything under the water.
so the energy isn't coming from the slow movement of the tidewater past the propeller? is it mainly from the wings making the thing move around in the water faster than the tide and that turns the propeller? else if the former couldn't they just put a an underwater windmill on the sea floor?
The movement is making the turbine go about 8-10 times faster than the current which is exactly what gives a 28 tonnes turbine the same output as other tidal 800 tonnes turbines placed on the sea floor. And it works well. Also cheap maintainence due to light weight and far reached automatisation. Do you see it now?
The turbine power formula is: P = 0.5 * ρ * A * Cp * v^3 The power is dependent on velocity cubed. So for a relative speed of the kite/dragon that could be up to x10 times the actual tidal stream you would generate x1000 more power given the same sweep area of the turbine compared to a stationary turbine on the sea floor.
Great concept I hope succeeds especially since water is 4X denser than air I believe... I hope the Bay of Fundy gets some of these going because they've have tidal dreams for years but so far no technology has survived the ruggedness long enough in test mode to justify a permanent solution...
DFO (Dept. of fisheries and oceans - Canada's Enviro Nazis) have cancelled many tidal projects in Canada because there is a chance the propellers could hurt fish. I don't know how they contend with boats with screw props.
"Air", earth atmosphere at sea level and roughly 4 degrees C, has a density of about 0.9 kg per cubic meter. Water at 4 C. has a density of very close to 1 g per millilitre. A millilitre is a volume equivalent to one cubic centimeter, which is one millionth of a cubic meter. This means water has a density of 1 million grams per cubic meter, or 1,000 kg. It is therefore 1000 / 0.9 times denser than air = about 1100 times as dense.
Wow, What will be the impact of slowing the water down. Could affect the whole eco system around the Islands. None of this technology should be allowed until full studies on the environment are done on the environment!!
Mooring, mooring, mooring. It's always the mooring that fails with this type of devices. It should be sturdy enough to withstand the storm of the century and light enough for not to prevent action.
@@Ginflyer Acceleration and deceleration forces of the wave affects down to the depth which is half of the wave length. 100 m long ocean waves are common. Mooring cable and its fixing points are under constant ripping and bending forces caused by waves and by the movement when it "kites".
@@TommiLipponen of course the cable is made to wtihstand the forces that are created. And no the wather doesnt affect the kite with more forces than what its already creating itself while moving in a figure of 8.
@@Jonas-wh2zq This is an important and innovative project. New way to produce clean base energy, like the gentleman in video said. I wish nothing but success for it. And, by the way, Faroe Islands is a wonderful place, I visited there and loved its nature and scenery.
@@obsidianjane4413 its not a billion dollar company that can buy its way through regulations. There has been studies from Universities and compnys and there has been no impact. The animals steer away from the kite.
We? Some of us are. There has been funding from the EU in a smaller scale as well. Hopefully The Faroe Islands will get more fundning so they can decide to make parks with these dragons.
The problem there is transmission from storage back to 🌎. Loss of power in transmission makes the prospect less inviting. Besides, we need low tech solutions, close to home, not mega projects that will benefit large corporations. See Boeing right now: too entrenched for us to get out from under.

It is in the water. It is ready to start producing Like 4-5 dragons/year atm. They can't have big production facilities before they have purchase orders.
Wouldn't replaceing the hole hydro electric generator with a new, fixed or maintained one be more sufficient, towing all the way from Denmark two times in stead of four, it would half the carbon foot print.
It’s towed to the nearest harbour (30 min away) by a small utility vessel called Gronanes. Look it up on marine traffic. Takes in total 2 hours from the boat leave harbour. This is every 4-6 months (planned maintenance)
@Ginflyer Guessing the chain would be the most worn part ? Due to the temperature of the water the ball bearings wouldn't get hot expand and wear out as quick. Due to water being more denser than air im also guessing the underbody would need filling and painting, air can carry micro partials, but water could carry millimeter or evan centimeter particals ? Does it have a slip ring like a wind turbine ?
It is mor eexpensive than wind turbines but it is a baseload and u always know what you will produce so its much better than wind farms that is highly unpredictiable.
One of the reasons they are doing this in the Faroe Islands first is that the grid there is currently using a lot of oil which drives up the electricity costs. That means it is fairly easy to beat the current prices in the Faroe Islands. To be fully competitive in countries with lower electricity prices they need to drive down the costs by scaling up the production.
Depends if you factor in the cost of shitting in the air. It is immensely more economical if you factor in the damage that changes to our climate from increased CO2 will do, but if the consumer is passing those cost on the the commons then oil is very hard to beat.# Yes it is always cheaper. Oil is just easier to get somebody else to pay the price for.
Longer answer is considerably less than acidification, overfishing, pollution, or even conventional turbines. They move fast, but also look a bit like a fish, so the standard "don't get eaten" instincts will usually kick in for things to avoid them. There probably will still be the occasional dumb fish that gets taken out by them, but it has been studied and shown to have small impact. Best thing we can do for marine life is get to net zero as fast as possible, and stop worrying about the occasional direct damage we do in the process. We need to be in firefighting mode, and firefighters don't worry about a bit of water damage. Every tech will have some down sides. The answer to 'will it' is almost always yes, and there will never be a perfect silver bullet that is a simple answer, and holding out for one will doom us all. The question really should be 'To what extent will it...' if we want to get anything done.
Wow, I was expecting to see 2 propellers rotating in opposite directions at 3:04, with the glider staying still and the props turning on-board generators. Instead, there is one propeller, and the glider moves. I don't get it.
Glider converts low flow speed into high flow speed by doing circuits. Turbine converts high flow speed to electricity. The advantage is that the glider is versatile and simple, so can convert a wide variety of conditions to optimal conditions at the turbine, letting it produce rated load over the majority of the day and making good use of the all the expensive parts.
And this is why we use tax money to try out new technologies. Something like this could really help remove heat from power generation, and start to make the world habitable for our grandchildren. That's where we are people: hoping to make the planet better for our grandchildren
I've followed this company for a while, they have a youtube channel with webinars where people have asked the same question - the kits don't move fast enough and so sea life can avoid the kites. If anything then an exclusionary fishing zone will be of far greater benefit, anywhere you can keep bottom trawlers away from the sea floor will be a great benefit for all marine species.
Its not a bigger problem than for other ships. Also when moving fast these things don't get stuck. They have service intervals for 6 months when one dragon is up for service an other on takes its place in the meantime in the parks.
@@obsidianjane4413 get your facts straight. The current 1,2 megawatt has been in the water for over 4 months. Before that they used 2 0,1MW kites. It has also been one prototype running off the coast in Holyhead for a long time.
Thanks for the replies. It still leaves me wondering a bit. I'm not sure, but aren't there some large ocean-going ships that take more water than that when fully loaded? Like one of those monster cargo ships? So what is the maximum depth for one of these "kites"? I suppose it would need to adjust for where it is positioned. Not so many of those huge ships in the Faroes.
@@farmergiles1065 yes. You wouldn't place the parks under the fairways where the big ships are supposed to go. The parks are strategically placed to minimize impact of marine traffic and other things.
Worth noting is that these are not dumb structures, they are able to maneuverer if necessary. It would be annoying to have to turn off your generators (or run them suboptimally) when a large ship is going past, but it is absolutely possible with zero hardware modifications.

Yes (8-10m clearnce to the surface allows ships pass above) and yes (No impact. Been monitored 4 a log while by universities and marine institutions)
Wow this likes like the Tesla of renewable energy.
I think it actually sounds quite good
I hope its not like Tesla 😂
Opening up a market that didn't exist ... Energy didn't exist as a market before?
Is it marine/wildlife friendly though.....
who cares?
They haven't noticed any negative impacts on wildlife during the long time testings that have been done.
Studys and monitoring has been going on for a long while - no accidents or other significant impact.
beautiful
That's a good idea for that area in with feasible power intake project like this. 👍👍Every geographical area has its potential on for all kinds of new energy power project alike and other from earths elements and solar and collective combination progressive systems together and energy storage with each other and other newer energy storage polarization techniques in fluid dynamics in coming future:)
More science, less XR propaganda. Well done Engineers.
More intermittent energy generation, ultimately dependent on the cost and reliability of energy transmission and storage.
Storage not needed.
what happened to the pelamis wave converter? Is it still operational
太陽の光をエネルギー化する太陽電池と同様に太陽の引力で発生する海流を利用する発電、素晴らしいではないか。若かったらこういう会社で働きたい。
These look amazing and I wholeheartedly agree that we need to embrace renewables... but what about marine megafauna? Whales already have to contend with submarine noise, entanglement and boat strikes. I hope they've done their impact assessments and plan to place farms accordingly.
They have done lots of research on this and found no problems, the animals just avoid them cuz they are not super fast. They have said that if it becomes a problem they can just add a sensor and shut it off when whales are close
Thanks, good to hear.
Tidal and wave power are so underutilised
Because it is shit
@@Movetheproduct in what way?
Shit as in ”there’s more tidal energy in the world than any nuclear reactors ever built”. Tell us more about your statement @Aria432

Will there be any risk to marine life? Im all in for the kites , just that woundering if they have done a study.
Something that required this many engineers and scientists, I’m sure a few marine biologists were involved somewhere.
@@nicholascurry3734never assume.
Do boats and submarines do?
Do boats and submarines do?
Studies have be done around the tidal generators of Shetland.
Drones are currently being looked at by the government & will be regulated so anything like this ok if they are using it but something like this could be made into basically underwater drones just like the ones anyone can buy. How cool would it be to get a view of everything under the water.
These ones have no engine. It will not be able to fly unless its connected to the bottom. It works just like a kite except it has rodders.
so the energy isn't coming from the slow movement of the tidewater past the propeller? is it mainly from the wings making the thing move around in the water faster than the tide and that turns the propeller? else if the former couldn't they just put a an underwater windmill on the sea floor?
Yes, yes and no. It's the underwater equivalent of the failed Makani energy kite.
The movement is making the turbine go about 8-10 times faster than the current which is exactly what gives a 28 tonnes turbine the same output as other tidal 800 tonnes turbines placed on the sea floor. And it works well. Also cheap maintainence due to light weight and far reached automatisation.
Do you see it now?
The turbine power formula is:
P = 0.5 * ρ * A * Cp * v^3
The power is dependent on velocity cubed.
So for a relative speed of the kite/dragon that could be up to x10 times the actual tidal stream you would generate x1000 more power given the same sweep area of the turbine compared to a stationary turbine on the sea floor.
It's far too early to declare "cheap maintenance" on these.
How does it connect to the grid?
It uses sea cables on the bottom of the ocean from the parks.
maybe glider is a better term than kites
It flies just like a kite except it got rudders.
Great concept I hope succeeds especially since water is 4X denser than air I believe... I hope the Bay of Fundy gets some of these going because they've have tidal dreams for years but so far no technology has survived the ruggedness long enough in test mode to justify a permanent solution...
Around 800 times denser than air! A great concept :)
DFO (Dept. of fisheries and oceans - Canada's Enviro Nazis) have cancelled many tidal projects in Canada because there is a chance the propellers could hurt fish. I don't know how they contend with boats with screw props.
"Air", earth atmosphere at sea level and roughly 4 degrees C, has a density of about 0.9 kg per cubic meter. Water at 4 C. has a density of very close to 1 g per millilitre. A millilitre is a volume equivalent to one cubic centimeter, which is one millionth of a cubic meter. This means water has a density of 1 million grams per cubic meter, or 1,000 kg. It is therefore 1000 / 0.9 times denser than air = about 1100 times as dense.
@@theloniousm4337such people are just stupid.
Wow super cool 😊
GOOD
Wow, What will be the impact of slowing the water down. Could affect the whole eco system around the Islands. None of this technology should be allowed until full studies on the environment are done on the environment!!
There has definitely been calculations. They will not stop the water. It will take a very small amount of power from the tidal.
>we're opening up a market that didn't exist before
what market? electricity?
Mooring, mooring, mooring. It's always the mooring that fails with this type of devices. It should be sturdy enough to withstand the storm of the century and light enough for not to prevent action.
No need. It’s minimum 8-12 meters under the surface. No weather will bother it there.
@@Ginflyer Acceleration and deceleration forces of the wave affects down to the depth which is half of the wave length. 100 m long ocean waves are common. Mooring cable and its fixing points are under constant ripping and bending forces caused by waves and by the movement when it "kites".
@@TommiLipponen of course the cable is made to wtihstand the forces that are created. And no the wather doesnt affect the kite with more forces than what its already creating itself while moving in a figure of 8.
@@Jonas-wh2zq This is an important and innovative project. New way to produce clean base energy, like the gentleman in video said. I wish nothing but success for it. And, by the way, Faroe Islands is a wonderful place, I visited there and loved its nature and scenery.

Answer who cares.
@@obsidianjane4413 its not a billion dollar company that can buy its way through regulations. There has been studies from Universities and compnys and there has been no impact. The animals steer away from the kite.
"Why aren't we funding this!?"
We? Some of us are. There has been funding from the EU in a smaller scale as well. Hopefully The Faroe Islands will get more fundning so they can decide to make parks with these dragons.
Do fisherman have concerns about these underwater arrays? Will these arrays affect the annual pilot whale roundup (the grind)?
We need to know how to possess energy from the Oceans....
P.S.

I wonder what happened to the space-based solar panel technology? European scientists said it was easy to create
I think CalTech did tech demo recently, but the launch cost & transmission loss haven't got low enough to compete renewables on earth.
The problem there is transmission from storage back to 🌎. Loss of power in transmission makes the prospect less inviting. Besides, we need low tech solutions, close to home, not mega projects that will benefit large corporations. See Boeing right now: too entrenched for us to get out from under.
Why would you have solar panels in space? How you get them up there?
Will the tidal kites be placed deep enough so as to not obstruct boating and shipping?
Yes. Below regular ships. Larger shipping vessels are not supposed to be at the same spots.
stupid question, sorry if it has already been asked. what if it encounters a school of fish? instant fishsticks?
0:40 it looks a little like a kite be-CAAUSE it's de-SIIGNED to FLYY through the water
Imagine a big sail ship with this tech to collect energy in open sea to be transferred to commercial vessels or brought back to shore, hydrogen!,compressed air even battery, sails area are cheaper and more than double as efficient as blades.
I can already hear the environmentalists complaining about the damage it will have on the Marine life...........
Why would they?
Superb. What is the Technology Readiness Level of this product? - Media should always report TRL. This should be in the culture! We need to know realistically as public at what stage of development each new innovation is. Thanks 🙂
It is in the water. It is ready to start producing Like 4-5 dragons/year atm. They can't have big production facilities before they have purchase orders.
TRL is on its way from 8 to 9 atm.

Wouldn't replaceing the hole hydro electric generator with a new, fixed or maintained one be more sufficient, towing all the way from Denmark two times in stead of four, it would half the carbon foot print.
It’s towed to the nearest harbour (30 min away) by a small utility vessel called Gronanes. Look it up on marine traffic. Takes in total 2 hours from the boat leave harbour. This is every 4-6 months (planned maintenance)
@Ginflyer Guessing the chain would be the most worn part ? Due to the temperature of the water the ball bearings wouldn't get hot expand and wear out as quick. Due to water being more denser than air im also guessing the underbody would need filling and painting, air can carry micro partials, but water could carry millimeter or evan centimeter particals ? Does it have a slip ring like a wind turbine ?
So what sort of effect would this have on marine life? No mention of it in the report. 🤔
Quite a few studies has been made by universities. Before ut was approved by the Faroe Island. Studies has been made both in the UK and in the Faroes.
I wonder how those dragons will affect marine life and all nature.
A lot less than speed boats and oil rigs. Thats for sure. Its not faster than about 20 knots. Lotd of crestures in the water is faster then that.
✌🏻😎🏴Can we cover up the propellers so it doesn’t cut up animals in the ocean? This is a good idea.
Does it produce electricity about the same as the oil power plants ? Or is it only economical at high energy costs to the consumer?
It is mor eexpensive than wind turbines but it is a baseload and u always know what you will produce so its much better than wind farms that is highly unpredictiable.
Unlike oil the energy source is free.
One of the reasons they are doing this in the Faroe Islands first is that the grid there is currently using a lot of oil which drives up the electricity costs. That means it is fairly easy to beat the current prices in the Faroe Islands. To be fully competitive in countries with lower electricity prices they need to drive down the costs by scaling up the production.
Depends if you factor in the cost of shitting in the air. It is immensely more economical if you factor in the damage that changes to our climate from increased CO2 will do, but if the consumer is passing those cost on the the commons then oil is very hard to beat.#
Yes it is always cheaper. Oil is just easier to get somebody else to pay the price for.
Will it affect/hurt the animals in ocean?
Short answer no. Many studies has been made.
Infinitly less than fossil fuel burnings is...
Longer answer is considerably less than acidification, overfishing, pollution, or even conventional turbines. They move fast, but also look a bit like a fish, so the standard "don't get eaten" instincts will usually kick in for things to avoid them. There probably will still be the occasional dumb fish that gets taken out by them, but it has been studied and shown to have small impact.
Best thing we can do for marine life is get to net zero as fast as possible, and stop worrying about the occasional direct damage we do in the process. We need to be in firefighting mode, and firefighters don't worry about a bit of water damage. Every tech will have some down sides. The answer to 'will it' is almost always yes, and there will never be a perfect silver bullet that is a simple answer, and holding out for one will doom us all. The question really should be 'To what extent will it...' if we want to get anything done.
Wow, I was expecting to see 2 propellers rotating in opposite directions at 3:04, with the glider staying still and the props turning on-board generators. Instead, there is one propeller, and the glider moves. I don't get it.
Tides flow in different directions at different times of each day... it flows into a bay... and goes back out, several hours later..... twice daily..
if the glider would be standing still you wouldn't generate as much power as when it is moving in a figure of 8. Its is a very big difference.
Glider converts low flow speed into high flow speed by doing circuits. Turbine converts high flow speed to electricity. The advantage is that the glider is versatile and simple, so can convert a wide variety of conditions to optimal conditions at the turbine, letting it produce rated load over the majority of the day and making good use of the all the expensive parts.
And this is why we use tax money to try out new technologies. Something like this could really help remove heat from power generation, and start to make the world habitable for our grandchildren. That's where we are people: hoping to make the planet better for our grandchildren
I wonder how many dolphins, Whales, and other sea creatures will be affected by this ? Seems pretty crazy.
Been studied and found no effect on animals, they just avoid them. Also they could just be shut off for 10minutes if a group of whales were close
I've followed this company for a while, they have a youtube channel with webinars where people have asked the same question - the kits don't move fast enough and so sea life can avoid the kites. If anything then an exclusionary fishing zone will be of far greater benefit, anywhere you can keep bottom trawlers away from the sea floor will be a great benefit for all marine species.
Any battery banks caught on fire.
This solution makes the need for battery banks much lower.
How do these machines impact marine life?
No impact. Been monitored 4 a log while by universities and marine institutions.
I wonder how long before they get barnacles?
Its not a bigger problem than for other ships. Also when moving fast these things don't get stuck. They have service intervals for 6 months when one dragon is up for service an other on takes its place in the meantime in the parks.
And what about the wildlife?
Zero incidents in 10 years of testing. A lot of research has been made
@@Ginflyer Of a single prototype that has only been actually in the water for a few hours.
@@obsidianjane4413 get your facts straight. The current 1,2 megawatt has been in the water for over 4 months. Before that they used 2 0,1MW kites. It has also been one prototype running off the coast in Holyhead for a long time.
"Swimming beneath": at what depth? Surely there must be accommodation to prevent conflicts with navigation?!
It "flies" about up to 8-10 meter below water levels as i remember. Don't anchor or take your submarine in those areas. ^^
The operating depth is minimum 8 meters below surface, so no interfearence with most marine traffic
Thanks for the replies. It still leaves me wondering a bit. I'm not sure, but aren't there some large ocean-going ships that take more water than that when fully loaded? Like one of those monster cargo ships? So what is the maximum depth for one of these "kites"? I suppose it would need to adjust for where it is positioned. Not so many of those huge ships in the Faroes.
@@farmergiles1065 yes. You wouldn't place the parks under the fairways where the big ships are supposed to go. The parks are strategically placed to minimize impact of marine traffic and other things.
Worth noting is that these are not dumb structures, they are able to maneuverer if necessary. It would be annoying to have to turn off your generators (or run them suboptimally) when a large ship is going past, but it is absolutely possible with zero hardware modifications.
Genius idea, but have we considered danger to marine life?
They have. Studies has been made by independent party. No, impacts was noticed. The Faroe Islands thought this was important as well.
Labour need to look at this, for their own drive to net (sorry) zero.
