Very good video! However tt seems you have bit old LCOE values for Minesto. For tidal with 100MW installed the LCOE is at 70Euro and 55Euro for ocean current After 1GW installed Minesto will be one of the most cost effective energy source in world
How about a video on Wave energy?
Could one be using the pressure? like very deep.. i dont know how, but you know, there is alot of pressure in very deep, just a thought,, maybe something like the basketball that generates.. idk
@@RoshanMenon90 yes i'm thinking about that too...installing wave energy system can help reduce coastal erosion
Waveenergy is much more inmature. The equipmemt must servive hard wheter and though enviroment and that means heavy equipmemt, have equipment is expansiv to build och maintain. LCOE is than very high. If they make it smaller the effectivness goes down and it will break. Though formula!!
Isn't it a crazy idea, that 'Tidal Power' is technically 'Moon Power' 😁
Solar power and now lunar power
@@Gingersnaps_the_pumpkin_kitty the name of the sun is actualy sol thats why its called (sol ar) power and the moon is luna so (luna r) power cool right
Technically it's an interplay between earth's rotation and the moon's orbit, and also the sun is involved to a more limited extent, but yes it's pretty cool!
And wind power is technically solar
@@Maxs.Grandma.trilionare lol m0r0n
Just wanted to say I've been watching informative content on YT for years now and every video you put out is absolutely top notch. This channel is a gold standard for educational, thought-provoking, and informative content. Please keep going above and beyond.
Wow ... that means a lot to hear. Thanks so much.
@@UndecidedMF I agree with ekoden. Your videos are well thought out, written, photographed and edited meticulously. There’s never a video where I don’t learn something, while being entertained. Everyone needs to know more about energy and our choices for obtaining power as we go forward into an economy which will probably require more energy while we must reduce our carbon footprint. If we succeed, your videos will have been a significant part of that success, and I hope you are rewarded appropriately. I thank you on behalf of my grandchildren. Keep up the great work!
Top notch theory but what is viable in practice is another thing , only in tests will this prove useful ?
I must admit that I was rather skeptical when I clicked on this video due to my own biases from what I've heard, but I'm pleasantly surprised that nearly every method you've presented have real world working models that have date from the field to back up their claims.
Biggest issues that I can see going forward with tidal systems like these are long term maintenance (barnacles, molluscs and basically sea slime), getting the power to shore in the case of deep water installations (the kite) and of course permits/insurance and such.
A potentially great location for a system like the VAWT design might be between some of the bridge piers of bridges that cross tidal inlets or large rivers. You couldn't block ALL of the piers, have to leave passage for boats, but some power generated is better than none!
the underwater noise pollution is also problematic for marine life... idk what can be done to make this a win/win honestly because no matter which system you use, it generates noise, and noise is very bad for fishes because they cant hear their predators and so on....
@@_Caedwyn Most, if not all of these designs are relatively slow speed systems. So their noise is going to be fairly low-level (even for the fish and cetaceans in the area), not like high speed turbines in a traditional hydro-power setup or boat props. I will agree this is a potentially valid concern though, especially if there are going to be several generating stations in a fairly small area.
there is maintenance with all power producing designs. if you lift the device out of the water for a week or so and the barnacles etc will die and shed off. not difficult to remove by many methods.
I worked 10 years ago for a German company working on Tidal Energy converters. Our system was basically a windmill under water.
Biggest problems(also today) are:
High costs for underwater plugs
High stress on underwater cables
Installation costs are hard to estimate (you need ships for Oil & Gas industry with DPS and these cost between 50k and 500k $ a day depending on season)
One thing to counter costs for cables would be to use these devices for offshore hydrogen production. For installation I am not sure what you could do.
Barnacles ? No worse than what the world shipping industry already face,
Undersea cables ? Likewise , beside any section in motion or tension,
Like any other type of generation , at least 25% extra should be built for redundancy / maintenance purposes .
I know one of the engineers at Orbital, they're quite proud of their system.
Not going to trash talk a contender here but a lot more is needed and technically proven to be possible.
@@cyklonetidalenergy7141
Another concern is a matter of where to place tidal power platforms, because of conservation of energy. That kinetic energy downstream will be affected depending on how many and where they are.
@@Aereto somewhat right direction of thought, but not really... it is very hard to max out a tidal sites flow potential. Much of it has too shallow water, affects shipping lanes or fisheries. You can't space the turbines too closely in the vortex wake fields of other turbines w/o loosing efficiency like in wind farms. There is a lot to learn about tidal power humans don't know exactly yet.
As I often say, "No silver bullet. Only silver buckshot."
With that in mind, we should look to a diversified suite of solutions harnessing the immense power of tidal currents.
As a former submariner, the brightest solution of the bunch so far is Orbital's design. The major downfall of undersea systems is maintenance. Orbital addresses this problem by designing retractable turbines that facilitate work on the surface. Additionally, the entire rig can be easily and affordably towed to port for more extensive maintenance or repairs.
The undulating membrane looks interesting. However, I worry about all the moving parts. The design just looks finicky to me.
And, while I'd love to see the undersea kite, its wind-harnessing cousin, Makani, failed spectacularly.
who said any one solution to cover all situations is the goal?
There's not really anything stopping the membrane from being mounted to a floating rig. In fact, given that they're so much more spatially efficient, this might even be easier/more cost-effective than mounting and operating multiple gigantic turbines and the heavy hydraulic systems that are required for raising and lowering them.
From what I could tell, Orbital's rig allows for the rotors' axis to be rotated 90 degrees as well to make it easier to lift & lower them without inducing undue stress on the system. That requires quite a few moving parts to accomplish, as well.
The membrane's going to need a bit more work, that much is clear, but the very high power output combined with the low spatial requirements I believe would make it a very strong contender.
The membrane looks like it needs some material science breakthroughs to properly implement the concept.
Stuff like Complient Mechanisms or Memory metal to reduce part count. Surfaces that are slippery to avoid marine buildup. OR... membranes designed to grow the specific types of marine plants that don't hinder the operation. Sorta like "bio armor".
Like Da Vinci's helicopter, there is more to consider then simple physics of power generation.
I really enjoy how positive and optimistic your videos are. Thank you, and keep up the amazing work!
It's hard to not get inspired by the ingenuity and innovations people are capable of. Thanks for watching!
Saw this on "Just have a think" last week, pretty cool stuff.
It's the same guy doing a different accent 😜
Always good to have another think
@@julianshepherd2038 so baldist. Bald people deserve to be seen as individuals rather than have people think they all look the same. And no …. Saying some of my best friends are bald won’t cut it.
@@andrewpaulhart My cousin, piebald at his HS graduation would largely agree. He, however claims to have discovered there is a bright side to it; losing his hair let much more sunshine fall on the solar cells powering his sex machine.

My grandfather invented and patented Octopus Systems Inc. in 1984 (no. 4,480,966) - I have his business plan and patent info. It was a series of connected units using wave energy that was self sustaining and collapsed down during storms. Unfortunately he developed dementia before he could develop the prototype. He also invented stamp cancelation machine for USPS and everyone's favorite, the tater tot machine.
My grandfather invented the toilet seat, the electric lightbulb and also trains, cars, fire, and the wheel
@@yesimfunatparties9337
Mine invented the patent system. Richer than Croesus he was.
All the numbers look to be new installation. What will they look like after exposure to the ocean environment, attached sea life, collisions with sea life, collisions with ocean pollution, etc?
I suggest that rope like thing and kites which can help us alot
maybe they should install at the pacific garbage patch so that the secondary purpose is to collect those rubbish floating around
I can see a few of these working for small isolated marine communities but that's as far as I'd take it. If they are produced on scale for a larger population, the eventual waste stream will be impressive. Especially considering the toxic waste from things like heavy metal laden lubricants and creation of the anti fouling coatings to prevent constant maintenance. Might as well start ocean mining. Our oceans are stressed enough and we can get more than enough energy from land, no need to put more junk in them, we need to start cleaning them.
@@anydaynow01 I don't see those extra boat hulls and propellers as having a high impact. After all, each one is just one more boat in the water. Compared with the scale of transcontinental shipping burning mega-tonnes of bunker fuel, it's nothing measurable.
@@fotoguru222 I don't see them being a huge ocean impact, unless abandoned at EOL, but things that are under water get pretty grungy pretty quick and I wonder what negative impact that will have on the efficiency.
The Nova scotia tidal power plant on the Annapolis River closed this past year. It was built as an experimental plant, and was operational longer than planned. It required repairs that was deemed not cost effective.
Cool! I was born in the Faroe Islands (don’t live there anymore) and have been following their development of different green strategies for some time now. They plan all land power production to come from renewables by 2030.
Love your videos... very pleasing to see all the possibilities!
One thing worth checking out is the Perth Wave Energy Project, or PWEP, which uses submerged floats at 25m depth to generate pressurised seawater, which is pumped back to shore. This is used to generate electricity AND can desalinate water, as the pressures involved are ideal for reverse osmosis desalination.
Love the amount of research you put into your videos! Thanks!
Let’s all say it together… Galvanic corrosion👏
I'm from the UK and, while I might live in Coventry, about as far away from the sea as you get on this island, I'm super-excited for tidal and wave power. Tidal power might be the UK's answer to green baseload, and marine energy in general might be our answer to the winter supply/demand problem. We get a lot of wind, but wind's pretty variable and we don't have the geography for conventional or pumped hydro at the scales we need. I am extremely excited to see what comes.
...also, you forgot about Simec Atlantis and their Meygen project. If and when it finishes building out, it'll be 400MW. It's the most conservative-looking tidal turbine I've seen - it looks like a wind turbine, just in the water...
Good video. Just an FYI, we pronounce Holyhead in Wales as Holly(the tree) head.
But the Scottish parliament sits at Holyrood pronounced Holyrood not Hollyrood.
@@julianshepherd2038 languages. eh?
@@scraggy983 Some great wit (Winston Churchill?) once said "the English language is all the separates two great peoples". And then we find out what the Scots and Irish have done to it! Who knew English was Jonathan Swift's "second language"? FR
Thanks for the tip!
@@julianshepherd2038 Um - I have never heard it pronounced Holyrood - always Hollyrood. Admittedly I only lived in Edinburgh for about 5 years, and in Scotland for 10...
And... that membrane idea will have minimal harmful impact on marine life! Although it's probably going to have its own issues with encrustation!!
Yeah I like that too, seems complicated mechanically.
I love how beautiful it is. Plus i imagine it will disrupt the sea life the least, resembling the movement of whales and skates as it does.
Absolutely. There are many antifouling products, hopefully one of them will allow for application onto flexible materials.
Tidal Power has been sat on for decades at this point, partly due to some vegans being living memes, in this instance:
Perfect Solution Fallacy "seatbelts don't save every life, therefore they should not be mandated despite saving many lives" and this being exploited by fossil fuels barons in exactly the same way they greenwashed plastic and claimed it would all be recyclable easily.
"every life is sacred, aw, poor fishies, we can't do tidal power, a tiny fraction of the estimated 3.5 TRILLION sea creatures might get caught and killed by turbines, so we're gonna help our enemies push fossil fuel as a more environmentally friendly alternative"
When climate activists SCREECH about slight imperfections to green energy, fossil fuel barons are there with a huge budget waiting to manipulate the situation.

@@michaelchildish I think they like clicks more than the earth.
The kite one seems like it would attract attention from sea life, I can imagine something being antagonized by it.
but also that could be a dope amusement park ride you know what Im sayin
this might be a solution for Puerto Rico's ongoing power problems.
If you notice most of the locations that he mentioned are fairly far north where the tides are much strong and much bigger. Done in Puerto Rico, those tides are only a few feet and would barely make any power.
@@christophernichols560 I think the minesto kite needs 1.2 m/s according to their website. So... 4ft/s?
Oh yeah. Anti corruption device?
Thanks for Great Video Matt, it seems to be a lot of questions about a lot of things, and I can answer some of them, regarding Minesto Kites. First of Deep Green is already a finished and launched product. Funded by EU (Most EU-funded company all cathagories). So it’s not a question, does it work or not it ”bloody well works” to quote COO.
Now when we have clerified that it comes questions about wildlife (i’m glad that so many suddenly is so enviromentally friendly). Anyway wildlife is something Minesto takes very seriously, there are three Universities following the project and make studies (like eveyone working in the seaenergy business). And Minesto have a kite in North Ireland for 8 yers i very wildlifeintense enviroment and had zero incidents. For fishes there are absolutly no problems because they are faster than the kite. Whales just seams to avoid it. There is a buildt in emergency stop if comes like cluster if stressed whales, the propeller stops, and the kite stops. So far no incidents in Wales, Northern Ireland and neither in Faroe Islands.
Regarding pollution i the sea I think this is question that are not that big, it will happen sooner or later but is very quickfix to change the kite. Shut it of, put in floating mode and bring another kite and change it. In Faroe Island that operation is done in less than an hour.
Harvesting energy from from OceanCurrent will slow down the currents and bring us back to Ice age?, To you who made that comment, go back school.
The submarine Kites are storm and Hurricane safe. Nothing happens down in tje stream…actually it will continue producing power as nothing happen.
About Corrosion:The kite is so deep in to the ocean so the enviroment is not that bad. The water is not that aggressiv. The surfacematerial is made of material that dont rust.
Some comments of the other Orbital O2 (2MW): this coloss weigh 300000kg/MW (Minesto 30times less). That and the fact its in the surface makes it both expensive, not so nice to see from coast, no traffic allowed (in Minesto case all trafic is allowed). So I have a hard time to see this in larger numbers. It might be a Nishmarket for this.
The big difference between Vertical submerged tidalpowerplants and Minesto is that because Minsto sweep a large area it is so much more efficent. Up 6,8,10 times plus that the market for lowflow streams are extreamly larger.
Thanks! And thanks for the detailed comment.
I just recently discovered your channel, of course I subbed. Your content is totally different from other science channels, you seem to be more of a postive and optimistic science channel and I love it. cheers to more videos in the future!
Thanks so much!
Thanks for sharing. Lots of interesting ideas. I have loved the idea of tidal power for years. The best idea I had heard in a long time was the underwater sea carpets. I’m guessing that the 5 mw flexing one may be a maturing of that. They had said the technology was gaining interest based on its potential to protect harbors from erosion alone with energy being an additional benefit. The only problem I see is the incredible potential for high cost maintenance. The most maintenance free option I’ve heard of was the proposal of giant under water concrete venturi’s to be built under the Golden Gate Bridge. They were to be bidirectional and would be used to suck air from shore based vacuum powered generators. No moving parts under water. They expected to be able at minimum to produce 1000MW of power. My thought was imagine the foam in the water. 😂
great videos mate, keep it up!
Glad you like them!
Except for the membrane type, none of those designs seem to solve the harming marine life problem.
I think thts the safest design by far according to my LOGIC, all it has is membranes Floating, i dont think even fish are tht dumb to die in a swaying peice of metal
The minesto kite does not hurt marine wildlife. It is actually live right now so that is easy to study (which 3 universities are doing)
The thing is, all power plants have a heavy impact on the environment in some way. The greenest way to reduce emissions is to not produce them in the first place by using the energy we have more efficiently.
Oil plants are the source of some of the biggest catastrophes and climate change will kill much more than these energy sources.
Cats kill many more birds than wind parks btw.
If you want to save sealife get rid of single use plastic
I don't feel like any animal would want to go near any one of those things. But maybe the turbines might create a current that pulls animals so I don't know
@@maxmustsleep very true
Love your videos! Thanks for the great content 👊
Great video Matt. I have not had the chance to look into tidal power. Very interesting. It looks like it has a lot of potential.
Project Hail Mary is best "audiobook" I have ever listened to. A lot of credit goes to the narrator, Ray Porter.
I might give it a try. I've never been able to get into an audio book. Hearing a narrated story just doesn't seem to work well for me. I loved Weir's "The Martian" (his second book was only ok) and am looking forward to reading this one.
I just started it and I’m really enjoying it.
I can't repeat it often enough, humanity and the world will need vast amounts of clean, sustainable, emission-free and cheap energy in the future. Therefore, these tidal power plants also need to be supported to become a reality on a large scale.
As I said, the world and humanity will need vast amounts of clean, sustainable, emission-free and cheapest energy. When the fusion reactors and 5th generation nuclear reactors (dual fluid reactors) are ready for use, nothing will stand in the way of this energy either.
Every drop of energy comes from somewhere, wind energy stops the wind, tidal energy forces oceans to stand still. What are the consequences of that? . Humanity needs to consume less energy.
Become an Engineer and work design and systems!
@@ulisesrobles wind energy does not stop wind, what are you talking about ? Neither does this stop tides.
@@n.g.s1mple29 So energy comes from nowhere? Interesting point of view. Not very thermodinamically correct but insteresting.
This is exciting!
Thank you for making this.
One of your best videos Matt. There are a bunch of great ones you make. Thank you.
The membrane power plant looks amazing. Please keep us up to date on it
2nd that.
thanks for shedding a light on these renewable technologies. It makes me feel a little less pessimistic about the future
Great video, really interesting the membrane system. Thanks
I am always excited to see a new video uploaded...make more of these please!
More to come! Thanks for watching.
I like the kite scheme. Make sure to provide enough clearance to avoid collision. Can be quickly turned into challenging task to maximize energy harnessing in an array format.
I do have solar and love it but I have always thought that tidal or sea power had the greatest potential for 24\7 power generation. I'm just glad it's getting more traction.
I remember reading about tidal power generation in either Popular Mechanics or Popular Science, I had a subscription to both at a young age. This idea has stuck with me since and I'm glad to see some actual movement on the idea. Great video thanks.
Thanks for sharing! Innovative ideas like these can really leave a mark. I'm in awe of the ingenuity.
Great info Matt, thanks. 👍🏻
Thanks as always, Ron.
8:36 -- The "Deep Green" kite is fascinating because they chose to have the kite actively controlled by computer to keep a figure-8 pattern. There are several known wing-shapes which will automatically destabilize aircraft at all times (often used by fighter jets).
If one of those unstable wing-shapes had been used, the water kite would be be continuously unstable (moving) through the water, presumably generating the same amount of electricity but more efficiently since the figure-8 control mechanism could be abandoned.
Don’t know if I understood but the energy is generating bybthe speed of water going through the turbin. How will speed increase with tpur suggestion? By skipping figure 8
They were spun off from SAAB, a company that makes both submarines and fighter jets. I think they know what they're doing.
Unstable would mean that without control it would spin, stall and fall to the ocean floor. presumably there is some shape that would do figure 8s passively but they probably considered that.
This would be perfect for coastal nations in Africa! Thanks for sharing!
Southern waters usually get less tides than Northern European Countries, but nonetheless produces electricity
Yes! Keep up the good work. I love this train of thought. Not all correct but thinking in the right direction...imo
Great video Matt.
All I can imagine are the chopped up marine life in big piles below most of these blades. The flippy flappy thing might be less damaging
People said the same thing of birds and wind turbines...
Put them only in dead sea zones.
to me this was solved when they created the floor fan
put a medium grade screen around the blades
the fish can't get close to the blades because their too big to get passed the screen
such great editing!!!!HOW😶👏👏👏🙌
I've got a great video editor!
Good Job Matt!! Please keep going
Thanks! Will do!
I am impressed with the progress of the different tech'. Thanks for the video.
I always thought that the waves are strongest only at the surface and the currents are negligible close to the floor.
Yeah, I imagined that the bottom was stationary while the water on top sloshed back and forth. But maybe it's just the wind that does that, maybe the tides do the opposite.
Hail Mary is a fantastic book!!! Rocky
Thanks for always covering interesting tech. I'm wondering on the practical applications of tethering undulating membranes behind sail boats to generate a little extra electrical power is practical or would that just create too much drag?
duude, love your videos, thanks a lot
Membrane sounds really good, also safe for marine life full 24/7 no interference power
Unlike wind and solar power generation tidal and wave power are capable of providing base-level generation just the same as Hydro and at a much higher level of efficiency! Initial capital costs and servicing may be higher but over the life of the equipment power generation should be lower per kilowatt!
Love your videos ❤️ thanks for what you do.
Thanks, Omar ... appreciate that.
Finally my request is catered..! Thank you so much bro! It's an amazing content
Would like to hear about any of these technologies that have little to no maintenance requirements, as that is the real problem with tidal energy. Thanks!
Yeah. Maintenance costs must be very high because salt water is so corrosive.
Minesto was spun off from SAAB, a company that is pretty good at building submarines. From what I gather, they have been focusing on keeping down maintenance costs from day 1.
@@Thoughtful_Balance Maintenance is factor, but Minesto solved that with an exchangesystem. Towing out a new system, change and than make the service on land. The system in Faroe Island for example is less than 1hour, from harbour to harbour. ( i think they went down to 30minutes in the end)
@@tidal-oceancurrents7552 thanks a lot for the information. It's much appreciated. 👍
Obviously they have gargantuan maintenance problems... moving surfaces underwater which are supposed to be hydrodynamic.... will grow barnacles etc.... Makes the wave energy guys doing blow turbines look sane.

How do you keep up with 2 channels. amazing
Sorry to inform you, but Practical Engineering is not his. That belongs to an actual engineer.

😂There must be something in the water. Me, Practical Engineering, Just Have A Think ... brothers from another mother.
Nice! Quite interesting topic, which does not get enough attention in mass media! I glad to hear that they worked on that particular project for 15 years! It means there is something worth looking at!
There was one form of energy that i saw a few years ago,
Effectively it was like an area of land with a cover that was supported about six foot at the edges that slowly increased toward the centre.
At the centre there was what looked like a cooling tower.
This was in a country like the U.K.
The air under thd cover heated up and because of the shape of the cover quickly made its way to the cooling tower but in the tower was a turbine.
It did not rely on wind and only required a small increase in temperature to operate the turbine.
It was first thought that this would be using farmland that because of the structure would stop growth of plants, however this was not the case in fact plants grew very well under it, by the way rain could go through the covering.It was also thought that it would only work during the day but it turned out that the heat stored in the ground was given up at night so there was a constant flow of air.
It worked very well but i never heard about it again.
That membrane was way too many moving parts, crustaceans will attach to it and render it unusable.
maybe we can make it taste bad.
@@clobberelladoesntreadcomme9920 some don't eat it, just attach to it and filter the surrounding water
By sending a current through the hull the way they deal with ships it can keep it from rusting and crustaceans attaching to it, I think.
@@MissMarinaCapri yeah thing is they have evolved to attach to whatever they can and all it takes is them to attach to one to succeed and the rest will follow
@@makatron , really ? That’s interesting and surprising.
This issue isn’t “can it work” as it clearly works. The real issue is will it catch on, get funded and insured and adopted by utility companies and municipalities
Very true, and in Minestos case, the flying kite. That journey has already begun. SEV utility company i Faraoe Island is showing the path. With that said, floting wind have taken 90% of the attention. and most of the funding so far but we can clearly see that it will change. The kites are ahead of floating wind andis both cheaper and more stable. Hopefully we will be able to see cooperated arrays between floating wind and the kites.
A huge issue as well is reliability. Water is very abrasive, the salt in saltwater is very corrosive, and tidal power is quite extreme.
Many of the tidal projects that have been deployed in the past 5-10 years have broken or failed in some way.
We might need to take a leap in material sciences to get good reliable/strong products which can be used underwater to harness the intense power of tidal energy. It wouod need to be underwater with minimal maintenance for at least 20-30 years for the technology to prove viable. We're just not there yet.
But every experiment, every new deployment, every new video outlining the potential of the technology brings us one step closer.
Wow Matt. Such a classy way of going about everything.
Good work Matt
I see no great future for tidal power.... in Switzerland where I live :)
"Can underwater turbines work?"
Yes...all hydro-electric turbines work under water. And what's more, if they were above water, they would be useless.
Indeed, it takes a different design to capture wind vs tidal energy, similar concept though.
HAHAHA!!! Brilliant!
Thanks for the book suggestion, downloading now :)
Really interesting idea. You did an excellent job in your research and bringing the most update information to the market that most of viewers do not know about. It would be interesting if private consumers convert swimming pools into some type of wave source to power individual homes or even use the Mississippi River for a source. Lots of ideas to pursue but like you said complex technologies.
How are tidal generators' performance and financial viability impacted by the sea life that plagues ships and submarines - barnacles, seaweed, and molluscs?
They can be raised out the water are night for maintenance when power demand is low.
@@scottwhitley3392 Daily maintenance adds costs and increases wear, which drives costs up.
@@arnoldroquerre6912 I’m well aware of that. I’m a qualified Marine Engineer. Sacrificial anodes and coatings can be added to greatly reduce the rate of corrosion. Also considering the facts that tidal brings reliable, consistent and predictable energy compared to wind I’d say the added maintenance costs over a similar rated offshore wind turbine is worth it.
Check out SeaTwirl and their vertical-axis wind turbines!
I love that you give me hope!
Brilliant. The ideas presented are great and I like them all. But what is BRILLIANT, is your quality of programming Sir.
Great material, presented in an engaging and extremely professional manner and - each - one - keeps - getting - better! Kudos.
They need to keep cleaning the ocean, that's for dang sure. GO 4OCEAN, ETC
Luxury or no luxury always be proud of your brand and try working to improve. I love luxurious lifestyles. All thanks to crypto I just got my first Lamborghini 💝. My advice to y'all invest in cryptocurrency or gold.
Despite the economic crisis it's still a good time to invest in Gold and Crypto
I heard his strategies are really good
Yeah
My first Investment with expert Tony Gallippi has earned me profit of over $24,320 US dollars and ever since then he has been delivering
Wow... He has really made a good name for himself, He's My Account Manager too
He's obviously the best I invested 4000USD with him and in 9 days I made a profit of 16,107USD
I live in New Brunswick and was very excited that my region was mentioned. I've known that there have been tidal power projects being developed for many years. I hope it becomes a viable power generation method as we move towards sustainable and non-carbon-emitting generation.
That's good stuff!
Very informative video .. thanks Matt

Great video. Perhaps you can compile a future video on floating paddle wheel turbines for river communities.
Yes I believe that as cost goes down. The demand is there now. I ran across your channel yesterday. I can not thank you enough for your channel. I saw the video on solar panels as roofing panels. I live in Phoenix I am on my 3rd home. Solar power to me is the only way to go. Looking forward to the future to see the newest version of solar panels. Thank you again for the information and showing the newest product on the market.
yes, I think these will catch on and would be an obvious skill transition for those who have been working on or around offshore oil rigs. I have read "Project Hail Mary" three times since I got it on ebook format in may, I agree with you I find Mr. Weir's books entertaining, hopeful and inspirational. Robert Llewellyn's Fully Charged did a couple of shows on Orkney and the different tidal generation projects that were being researched. Great work, really enjoy your channel.
Very cool stuff, I'm a big fan of tidal and ocean current power harnessing, provided we don't disrupt fisheries in the process.
There is also a method of generating tidal energy via buoyancy floats but I don't have any links to info on that, maybe it is not effective enough since it can only work in areas of large tide changes.
incredible video editing as always with the music slows at starting.
sounds great. proceed with the research.
I also think that for small individual or isolated areas small floating "Run of river" water wheels or vortex style turbines are an excellent idea! The water wheel could be used where there is a high volume and slow flow, where the vortex is for high flow low volume!
High flow, low volume - waterfalls come to mind, but idk how scalable or practical this is for widespread solution, but could help places hard to build infrastructure potentially?
Would be interesting to see if they ever do anything about all the Geothermal energy that's just laying around.
Great idea
Thanks Matt.
Ooh this looks interesting
Thank you!
Thanks for watching, Robert.
There is an under water system from Australia called Ceto, I guess it's not quite 'tidal' but works on below surface sea movement, which is constant unlike tidal which has moments of no motion between rising and falling tides. Ceto 5 was originally used to pump water ashore under high pressure to turn a turbine, with the advantage of being able to be switched to a reverse osmosis membrane in times of low electricity need to create fresh water. The later version Ceto 6 transforms sea movement directly to electrical energy.
ooh, thanks so much for the recommendation for andy weir's book, I was waiting for him to publish something new
It's an incredible book ... really loved it.
@@UndecidedMF thanks again! I burned through it in two days, the narration is great too :D
Great video Matt I definitely think it is a solution to compensate for when the wind isn’t blowing and the sun isnt shinning. Would it be possible to attach these tidal power systems to off shore wind turbines? Can we capture the excess energy into batteries or stabilize the grid or to generate green hydrogen. There is a company in the UK trying to generate green hydrogen from wind turbines using seas water desalination and electrolysis process this could also aid at generating the power to do this. Just depends if it is commercially viable.
This is great
The Bay of Fundy is an amazing resource, and we should do what we can to use this huge amount of energy.
Wave power - is another way to generate electricity.
The underwater kite has a direct corollary in wind turbines - Makani had something that looks remarkably similar, and also flies in a figure 8.
There's also in interesting project with a pilot plant about to be launched (near Las Palmas IIRC). It uses energy from waves to run a pump that makes both electricity and at the same time also fresh water via reverse osmosis.
You have such a wonderful channel 👏👏👏
Great 👍
All very interesting exercises in design and engineering. Very skeptical of widespread use due to installation and maintenance costs.
you should do a video on wave power too as this has great potential as well
An important point to note when comparing the costs, particularly in the UK is that a new nuclear power plant currently in construction has been given a 30 year contract at £900 per MWh. So even though currently the costs are >£200 that's still way under the cost of new nuclear and without the decommissioning costs at the end.
