thanks

6:53 is a good spot too

Man that was painful I skipped out at 3 minutes. Horrible production.

The long build up told me it was going to be short line to the meat. 200KW for 12million. That's the ante price. I can tell you from personal experience maintaining anything mechanical in a salt environment is a nightmare. When you think about it you are talking about the energy density of moving air, which when we look at wind turbines their biggest drawback is low energy density. So the ''gluten'' diesel generator is going to be with them for awhile. Just calling that says something about where their head is.

You can please some of the KZfaq viewers some of the time, but no all of the viewers all of the time. Hell, you can't even get millions of Americans to get vaccinated for covid19 or wear a face mask.

@@ronlheureux7623 masks do not work, i.e. a spray painter who uses the paper masks will get paint in their lungs. The only mask that works is a respirator, which lasts 4 hours.

The paper mask is meant to stop the outgoing spread not incoming. So if everyone did use them properly there would be less contamination

There has been lots of scientific research into how affective masks are, that's why every major medical and scientific institute has recommended wearing them. Read that it can go as low as less than one percent of a chance of catching it off someone that has covid if that person is wearing a mask. Think about this a surgeon is doing a knee opp , hell any opp and they wear masks. It's not to stop them catching something off the patient it's to stop them infecting the patient.

The first wheel was probably not that durable but here we are! You go guys!

Plenty of oil off the Norway coast, give up for easy money.

Brilliant idea in the sense that it could work but probably unworkable if you think of how much governments have been squeezing out of oil over the years and that will be the benchmark . Are these things going to be squeezable ?

i have found a new wave energy model. lets imagine 700 meter tall , thin steel pipe. put it on sea vertical. pipe will go to a thin tunnel on the beach. the other side of that pipe will be 700 meters away in open sea. this side will have special rubber shape not to be broken in water. i cant guess how deep it is in 700 meter away. the tunnels on the beach will be portable like schale04 stadium. rubber shape in water will be like 5 dustpans. for example spain has big waves. this speacial shaped rubber dustpan cubes ( or whatever the shape is ?) will punch by wave. and 700 meters away , on the beach , the steel will compress in tunnel. how big will be this compress energy ? i think its cheap as train railways.the tunnels will be like schalke04's stadium and portable.with this electricity can u produce water from humid of air? lets make a pipe tunnel fridge 1.5 kilometers and give humid to this tunnel fridge. so cant u get drinking water from humid, if you make a 2 kilometers hose tunnel fridge. in the hose you will get humid and ice. than ice will be water.

Thanks for your feedback. I will work on it

Quite, I thought it was a travelogue.

I doubt your average american house uses 350000 kwh every year. The 200kw is peak performance, if we calculate with 12000 kwh per household and a peak uptime of 33%, you can supply around 49 houses with the energy. If they can drop the cost to 2 million dollar and throw in batteries, we have something to talk about.

It is more expensive than solar per watt, but it runs 24/7 vs 5-6 for solar. So is the equivalent of an 800kw Pv system likely. Cost is still way off, but RnD is never cheap

@@chasedaily8134 Those are the prices for a kwh not per kwp. If you want to consider full performance hours per year, it's around 8000 hours for nuclear vs 1000 in PV, ~3000 onshore wind and ~4500 offshore wind. So 1 kwp of nuclear with a 30 year runtime costs 29000€ while PV cost 1000€. Even if you build 8 times as much to get the same energy output, there is still a factor 3 between those two sources. PV and Wind correlate negatively, if you combine both with around 4 hours of grid storage, you already have a reliable power source that comes in much cheaper than 12 cents a kwh nuclear energy.

Another hole in the water to throw money into.

200 KW @24/7 without fossil input is really - really - cool, If you know how much fuel a 200 KW Diesel Generator consumes every hour... If you combine that with a larger LiFePo4 battery bank to handle peak demand load (maybe also stored within this boat) then you can power already a small village. As the only moving part seems to be the turbine, the vessel should last for a very long time. In the worst case, exchange the turbine every 5-10 years and the battery every 20-30 years (make sure to manage charge/discharge cycles to be always within the 20-80% range) .

@@johnranger9778 waves like wind... not always A boat is as a hole in the ocean you pour money into. boat stands for "break out another thousand" lol

Only applies to our current economic system. If we moved to a resource based economy the time factor changes the math dramatically :)

@@johnranger9778 If this needs to rely on batteries for energy storage, it’s a lost cause. Li-ion is far too expensive and the efficient losses are terrible. What’s more you need to use rectifiers to convert DC to AC for the grid, another nasty efficiency loss. Overall a bad idea.

The video says the "pilot project" has a budget of $12,000,000 to install a 200kW wave generator. That works out to $60,000 per kW! An installed diesel generator runs about $1,250.00 per kW. You could probably buy over a hundred years worth of diesel fuel and as many years of maintenance on that diesel generator with the remaining $58,750 per kW. Only a moron (crazed government bureaucrat or psycho politician) would commit public money for this venture. And that's the reason why most renewable energy technology development is taxpayer funded - private investors would never commit funds to a money losing venture. However, those committing public funds to these nutty ventures get away with it because most people are unfamiliar with the terms used or the scales they represent. The people who benefit most are those familiar with the terms/scales used; contractors, engineers, utility companies and all the other entities that participate in these boondoggles. On top of the cost, there's also the issue that renewable energy technologies are not "dispatch-able". Which is to say that when demand for electricity increases and the wave action at the time of need are not significant enough to provide full output of the wave generator, then other "dispatch-able" means of generation need to be brought online. This is true of any current renewable energy technology (wind, solar, etc.). That's where fossil fueled technologies and nuclear power will always have the edge on reliability. For an example of the utter incompetence of relying on renewable energy, think February 2021 in Texas where ERCOT exercised poor (some might even say "deadly") judgement in relying on the ability of renewable energy to keep up with increasing demand in a weather environment that severely curtailed the generating capacity of state's renewable energy technologies.

Did you work on the project or are you just looking for attention?

@@fakename3429 I am all for alternative energy, but they only seemed to talk about the good aspects, I was only joking, but to be fair the negatives should be pointed out.

@@fakename3429 Neither nor. frankm81m82 is just pointing at the fact, that the investment of 12 millions will generate the estimated average electrical power output to run 10-20 stovetops ... for perheaps a couple of years, if ever. It's so simple as that if you can read. Keep it factual and don't get personal, please. Let's wait just another year and we'll see, who's right. OK? See you again mid 2022 ...

Fair enough. The salt will rust the metal. But go work on a ship and they are painting all the time and we are still shipping. Just part of the deal when you are working in salt water. Learning how to get work out of somethings so common and close to population centers is worth some research into. You won't really get much of the many problems that they are running into out of a promotional video though. I was kind of hoping that you knew more of the project though (I doubted it though). Hopefully I didn't come across too crass.

@@fakename3429 You can't compare a ship to a fixed plant/object in salty waters with moving parts. Go ask the engineers and the builders of the "Mosé"-project to protect Venice. They are facing enormous problems they didn't expect at all. It's not only the salt in the water and air. It's the sand too. The oceans are living creatures. The costs of maintenance are far above of what they expected. The buliding costs already are actually nearly the triple of the planned ones and still not functional. And the maintenance costs are 10 times higher than they thought, at the moment namely an expected 100 million € per year ... For the same reasons no underwater turbine built to exploit the tidal currents in the bays of Norway or France has ever worked as planned. It's all far more difficult than you can immagine. This project of an artificial blowhole (and you don't have to be a prophet to foresee that) won't go anywhere. It's simply an economic suicide.

Theres been an active push back by the oil lobby to stop any subsidized approach to alternative energy

What do you do now for a living?

@@demilishing Still working at sea but in a completely different role. ROV pilot at the North Sea.

@@bulasev Sounds like a great job! Congratulations!

It is called Bass straight and you are right it has some of the biggest waves on Earth due to uplifting of water caused by two oceans meeting. I was on a ferry about 90 according to the captain it was the worst storm he had ever seen it damaged the engine beds.We were lucky to survive.

They had a Sydney Hobart yacht race with a terrible storm. And many died. When it’s bad it’s really bad

Can't help American documentary makers, they add America to everything.

@@tomcartmill401you sound jealous.

O-H.? Haha

I notice this in many 'factual' vvideos with ridiculous stock footage thrown in to illustrate the voice over. Annoying.

Those clips appeared when they said "King Island doesn't have sufficient energy to create tourist attractions like amusement parks, Perhaps with more energy they could do so"

I noticed this too. Pretty poor research.

You smashed all my dreams of going to King Island now. NO amusement Park ??? Ohhhh. LOL.

@@jonathanbedsole1671 What? The research is fine it is reasonable to show a picture of an object that you are talking about, even when your point is that there is insufficient power to have one.

@@weldmachine So you are going to get off the boat at King Island thinking. "What, No 'King amusement parks?, not enough 'king electricity to party all night, Who's running the 'king sh*t show?"

The power from this barge, does not need to be put ashore. Unfortunately, There will be "none". A teapot and achor lights is about everything this barge coud power. The cost of "antifouling" bottom paint alone, cost more than the barge can ever produce. The amount of diesel used in the production stage, will never be restored. This is unfortunately a total rip off for the taxpayers.

THE Power of the waves is a deceptively hard power source to tap into. The trouble is that the oscillating action of waves does not act like wind such that it can spin a turbine directly. Instead many company's have had to rely of liner motors on the surface of the waves which is also not as efficient. I suspect that backward motion action also was part of the inefficiency for them as well. Its nice to see a new take on the Water Column electric generator, however I would add one extra detail. I would also add a generator on the air *out-put* vent, as well. That way there world be electricity generation on both the air *in-take* as well as the air *out-put* vents.

Armchair engineer, ladies and gents.

Its possible because air compresses it may just compress and nothing would come in or out therefore no turbines would spin.

My thoughts exactly as soon as I saw the turbine exposed to the air. Let's not forget about all those sea birds who'll dump all over it and perhaps nest on it? ;0

It gets really windy and miserable there, that is why it is mainly beef and dairy usage (King Island cheese is great), very clean though. This whole video looked pathetic as they never showed any waves, just glass smooth ocean that couldn't power a desk fan. That area is best used for wind power.

It needs to happen.

Or a flapper valve that push/pulls all the air in the same direction through the same turbine.

Good idea Harley! Surely that would double the efficiency? The engineers (must?) have dismissed the idea for some reason - like to know why.

good one...mike

C'mon man, it's not about the money or payback, it's about the image.

And how much per KWH was the electricity first produced by Mr Nikola Tesla in his plant at Niagara Falls NY.

That's the cost of building a single small scale test unit to trial the technology.

@@CharlesGregory obviously a prototype will never pay itself. With continuous top production and no maintenance will have a payback of 140 years. So there is need to bring down costs like 20 or 30 times. And as many said.... salt water is a bitch. . Tidal seems more promising where tides are high. And is sure to come, not like wind or waves.

Exactly, first thing i thought when they were talking efficiency, more valves to redirect air or more turbines. They cant be the sharpest tools in the shed!

@@dougbubba3902 I was thinking another turbine for redundancy incase of failure aswell as valves tend to get clogged up from barnacles and trash. But I guess a good direction altering duct set up like a blow back arrestor would with more efficiency and would stay clean due to it's one sided operation.

the video really doesn't go into any detail, from my angle it looks like reed valves for exhaust, not sure barnacles can live above water, i guess those valves would be the susceptible efficiency of turbine in take, which is sucking in salt air!

@@dougbubba3902 thank you, I couldn't remember what the valves were called they used. I've had to remove that type from hydro dams, zebra muscles crawled up as high as 30ft and clogged them. I could only imagine what ocean barnacles would do. A little mist and they get all the nutrients they need. Nasty critters.

I would save the Hydrogen for a fuel cell, since combustion would waste a lot of the energy with the heat from the explosions. It would also require less maintenance, less safety features needed, and wouldn't create as much noise pollution.

Too many, unfortunately. And the worst part is that this is still intermittent, so add batteries to the bill.

They've been using wave generated power from coastal France since the 50s or 60s, I believe. Very cool hydro power.

You dirty boi

The snag with that Dawlish-Teignmouth part of the Devon coast is that prevailing winds blow from the West. Therefore waves on the sea wall are usually a fraction of what we see on the North Devon coast. Storms like the one which caused the 2014 collapse are very rare. It had also stood since 1850 with no problems. Storms big enough to collapse a stone and concrete railway embankment would also be pretty damaging to any wave power project. No to mention the equipment is pug ugly in an area of outstanding natural beauty.

You mean just like wind turbines? You underestimate the political stupidity.

...for the past 50 years I have heard a never-ending drone from the scientific community that 'clean and efficient fusion reactors are 20 years away'. But even this simple and elegant wave energy collection tool will be forgotten....

@@TheJmkovacs If the government throws enough money any crap idea it will survive for a while. Every wave generator tried so far has failed spectacularly and I sure this one will as well.

@@yanbu000 I was promised flying cars and jet-packs by now. Seems strange to throw away half the energy of the air-movement, Can't we have two turbines?

your right if you solve the worlds problems the politicians have nothing to fear the people with and loose their facist control - so they will squelch this.

I'm sure that price will come way down if this goes into mass production. The idea is sound though. Especially for small island applications.

I think they said that about the first electric bulb. Get it?

There are several other aspects to consider in the bargain, not the least of which is the desalination of sea water; but also in the added benefit of coastal protection, and in hydrogen production,(another useful energy source). All of which are very important in an island's energy production system, if not so much in a mainland locale. Plus, cost and energy production efficiency will likely both improve over time.

Government will invest in this just like the failed wind turbine. So it give the feel good feelings about going green. One good storm will destroy it and your $12 million is at the bottom of the sea.

thorium ?

我相信丹麥生產很高比例清潔能源。如果要成為清潔能源成功的使用者。就要在沒有風的時候。找尋北海以外其他風場。

That's the first thing I noticed too. They seem to be wasting half the energy. They might curve and taper the channels to increase air flow velocity as well.

I would direct the incoming air to the left (say), and close the vent at the top. out going air will go to the right.

so the turbine has blades at each end. One set for in, and one set for out

波浪令海水突然上升可能影響發電機。懷疑是這個原因。所以放棄一半能源。

What about giving the vessel additional temporary dive capabilities? I mean, only a few meters in shutdown state to sit out an upcoming hurricane?

Um, tides make waves. Wave energy grabs tide energy as well as wind energy. Further, while tide energy is predictable, it changes volume on a two-week cycle.

@@johnjerman3421 Yes under a desert and hundreds of klm from the nearest major city.

If you know anything about the initiation, design and all the other one off costs for a pilot project then you know it is many times the cost of a roll out. That $12.3 million will not represent the cost for rolling out such units. We don't know the feasibility and likely unit costs from this short clip.

Not totally free you have to pay for the thing and its upkeep,

Huh, that's saltwater out there in the ocean, not exactly going to green up things in the desert thru canals.

Do yourself a favour and read up on what has been done around Scotland and some UK Islands. Pay particular attention to what has been done on the Orkney Islands.
