- Energy from tides - how it is done and is it worthwhile? Why there are two tides each day. Discussion about height of tides including the Bay of Fundi and the Rance tidal energy facility on the coast of France. Undersea current turbines, and energy from waves are explained including Sea-Snakes (ship with a broken back) and shore-based air-compression wave-energy generators.
Tide goes in, tide goes out, he can explain that!
You really are a complete and utter idiot...

I can't stop watching your videos. Essential basics, perfectly simplified. Thank u so much
There is also the buoy type of wave power device.
Bobs up and down in the swell pulling a cable up and down. The cable is attached to a pump on the seafloor. The pump pressurised water which is piped to shore and spins a turbine on land. Or in theory is used directly for desalination
Johno very good Idea. I saw a trial wave power generator using about 4 55 gallon empty drums. As the wave comes by and raises it you get very high force from those drums hooked to a lever that is hooked to a hydraulic pump to presurize a large tank and 5 of these sustems tied to the central pressure collecting tank. (the tank acts like a capacitor) the Pressure tank then spins a turbine. It was a test case but it works,
@@jimbronson687 not the best idea. They've tried commercialising it and failed.
It works, it's just not as good as wind or solar.
The Bay of Fundy between Nova Scotia and New Brunswick Canada has an inline tubine testing the tidal power potential there right now. That is where the highest tides in the world occur. 66 feet or 20M at their peak! There is more water going through there every day then all of the rivers of the world combined. It is well worth testing in my mind. Of course fisheries and wales and such need to be looked after but still there is room for turbines. It is a very large and very powerful place
The UK has one particularly huge tide, in the Severn Estuary. It's capable of 14 metres or over 40 feet, the second biggest range in the world. Many projects have been proposed to utilise this huge amount of potential power. All have failed to get off the ground for many understandable explanations but typically one simple reason, lack of government support for a commercial installation. Which is a shame because reasonable estimates suggest that a significant percentage of the country's electrical demand could come from a tidal basin power project.
Please do a video on the integral fast reactor?
Ocean energy is fantastic since most people in the world live beside the ocean, Industry is there too
OTEC is one I would like to hear you cover as well profssor. Ocean Thermal Energy Converters. Hawaii has one. They look promising
Orkney is working hard on the under water turbines on the MW scale.
Bro I’ve learned so much from this series, thank you so much!
Man, i learn so much from you
This channel is amazing
As with dams, the blockage of silt movement is a big issue. Ocean currents do not have this drawback. The amount of available energy is enormous. I hope we work hard on this.

I’ve spent my life working in the Hydro Power Industry. All of them have the same issues ... Power in and power out are never 1.0 efficient . There is always a loss ... which always is to the environment.
Adding resistance to ocean currents ... has many draw backs when you think about it .
@@pushpushlambert8079 or as it where don't think about it. Look for $60,000 you can put a box on your desk that has stainless steel ribs and 1/4 turn cover release but more importantly 50 + 100 gigabytes of RAM not 100 + 50 I said 15 100 I said 1500 gigabytes or as Apple notes have to be 1.5 TB. So this is what this channel professor slobbers over when he wishes that he was a professor of say literature at the University of Chicago instead of some sort of engineering or economics quasi science professor. Because in the 1980's I used to joke around with a geophysicist at Caltech about how the English professors had certain work stations to do their word processing on that they couldn't get in the physics department at Caltech.
The point of your comment is that we cannot mess with God's work without understanding what's going to happen but 28 cores and a few pounds of electronics containing them at just 1500 watts at most beg to differ apple style. You can buy them like razor blades and in your closet and your friends closets a few hundred thousand dollars of those desktops X however many thousands friends you have you can figure it out that is apparently beyond your imagination buy simulation at the water molecule level just like we do it for weather in the gases on the surface
Now I understand tides,thx professor.
Nice
You could have been an artist.

Always a smart ass in the comments but gotta say good one lol
What about making a drift net with cables as thick as those on a suspension bridge and putting fan turbines in some of the squares. Afterwards suspend it from deep water bouys anchored from the Atlantic sea bed where the gulf stream is, and surround it with a dense mine field to protect it from awkward fishermen?
Nuclear industry already killed tidal energy push once ... remember the study "proving" tidal energy will be 18 more expensive. I cant find the ref video, instead of pistons each of sea-snake barrels rotate as the wave comes in.
Perfecting and making the new advancements in nuclear technology safe and reliable takes time and significant resources and willpower.
Underwater Turbines would be perfect. Maintenance would suck. But otherwise free energy right there.
Installing massive turbines underwater , then the hellish maint. You described? That’s free?
Nothing is “ free” . Especially when talking energy. Obviously you didn’t watch the whole series
As a rule of thumb, it is not environmentally friendly or particularly economic except in some ideal situations?
So when the place I am in is closest to the moon, the tide is high. I guess that also means that I loose weight at that time.
Centrifugal force on the back side.
Please use the metric system!
Re the reversible ocean cliff turbine system, as per the famous line by Colonel Hessler in the Battle of the Bulge (movie): “It can be done!” (LOL)
"The earth pulls away from the water"
........
Much as that makes sense, that has left me broken. Were I a weed enthusiast, that would have blown my high.
I'll be "That guy in the party whose mind was blown"-meme'd for a little bit.
I live on the Bay of Fundy we’re we have the largest tides in the world.
How is it that the moon's gravitational pull can cause the water to buldge on the surface of the earth despite the earth having a stronger gravitational pull, wouldn't the pull of earth prevent the weaker force of the moon from attracting the water?
It's a sum of gravitational vectors thing. Water is also pulled from the poles towards the equator making the tides more pronounced.
One is constant other is changing.
Hey Roller, Professor Ruzic didn't explain the tides accurately, which is why there's confusion. Check out this video: m.ua-cam.com/video/pwChk4S99i4/v-deo.html
I am pleasantly surprised to not see a thousand flat earther comments in reaction to his tidal drawings.
I actually kind of want to go to the flat earth conference just once lol
I always

Medieval People got energy from tides with Tidal Mills. I think the first ones were built in Rome. :)
seems like it'd be pretty easy to build large modular wave / wind generators in areas with the right shore conditions, particularly if they were made such a size as to be installed by a crane either on a barge, or on the shore.
The cylinder at the bottom of the sea will never turn. It would turn if the water current would only impact on either the lower or the higher half, as it does with turbines in hydroelectric dams. Otherwise the moment of the upper half in respect to the rotation axis will be cancelled with the other
Then use half a turbine
Half a turbine is no solution either. It will end up positioning itself opposite the flow of water. The only possible solution is to block half the rotating cylinder, as is done in hydroelectric turbines
You're thinking of a water-wheel design, not a turbine. Think of it as simply a propeller, inside a tube. The tube does not move. The propeller faces along the tube.
What?????
It is literally just a smaller much stronger version of a wind turbine. 3 blades, attached to a turbine, on top of a tower, anchored to the sea bed.
Is only
why not use a buoy system to generate power? every wave could give you power, not just tides
Maybe its time someone made a feasibility study into Salter's Duck again. en.m.wikipedia.org/wiki/Salter's_duck
The reversible turb'n, for when you need headwear for every day and a Sikh wedding.
Okay with the exception of the last two comment threads at the bottom which I guess they're at the bottom because they have the least like I have read and red everybody's comments so now it's my turn. I remember a very long time ago in energy bloggers who was probably poisoned by the Russians himself over a long. Of time because it wasn't pretty in the ending months after so many years of overt pressure campaigns against him even in the comments in terms of him not censoring the comments.
Water is very heavy and deep water the heaviest with the old line going Still Waters Run Deep. But with the ocean we see deep Waters that are not still which two translate is a very big deal.
So the professor introduces this argument against sea snakes that the torque which is the quality of the energy is too high. It's too high to waste on electricity that's for sure. But it's not too high to snap air into liquid or to capture the heat of doing so not just the product which is worth more than diesel. It's kind of ironic when you think about it these sea snakes with their hinges going up and down like a 12 year olds boys ass who has been seduced by the covid confined teenage girl next door they are-like oil pumps from The Beverly Hillbillies era and still scene in many parts of the world. It's the direct competition. Producing liquid nitrogen makes the price of diesel drop. The professor gets the message and disparages the technology. He's not aware of what he does but like a rat that's given treats figure it out unconsciously. You have to fund such people from the actual people directly not the corporations that are adversarial to the people or in the case of energy professors the mineral rights owners versus everybody else
The reversible turbine on the coast only has one flaw... birds exist.
Still not drawn to scale....🤣🤣🤣
The turbines work in both directions for tidal power. So the turbines runs most of the time.
If we always see the same face of the Moon ... does the Moon rotate?
yes, as it it is tidally locked to Earth it takes 28 days for a full rotation of the moon in relation to the sun, the same amount it takes to rotate around the Earth
I dont get it why its a bulge on opposite side also.
Perhaps it wasn't the clearest explanation. Denote the moon to earth distance as D, and earth's radius as R. The close side of the ocean experiences a force that is proportional to 1/D^2, the entire earth (as a the largely single solid mass) experiences a force proportional to 1/(D+R)^2 (effectively acting through the centre of mass), and ocean on the far experiences a force proportional to 1/(D+2R)^2.
Its the differences between the second and third numbers that creates the far bulge.
I hope this helps;

@@eliasandersson8236 I hope the visit the link that you provide because neither of you have discussed at all what the man is asking for. He's asking why it's not shallower on the other side of the Earth and I think that some discussion of the strength of the gravity of the sun is in order. But I haven't thought about this very much and I know that there is a misunderstanding on the part of the speaker or apparently at least that. He is talking about why there are four zones instead of three in terms of something or other right I mean it's extraordinary that is dividing a cycle into 4 instead of the sinus trouble cycle which would be to and of course I said sinusoidal and in Spanish deuce.
I think he makes the point but the problem that is causing the problem now I remember what the problem is the professor is overlooking the fact that despite the gravity being weak it's subtractive instead of additive on the near side. But there is some sort of thought disorder for this professor apparently he has a focus that allows them to spell gibberish he must be a coffee drinker or something.
On The Far Side of the Moon increases the gravitational attraction of the earth Aldo last that it's increases the gravitational attraction. The professor thinks about gravity apparently in the relativistic way of it being the same thing as acceleration. So the water is dropping on to the Earth despite having landed at 10 feet per second acceleration and that acceleration is reduced when the moon is full and in the opposite direction. In other words when it hits the surface it wants to get around based upon its ability to do so and what prevents it from doing so is competing water. the water that is on the top and bottom of the Earth in the drawing is both being pulled away from that spot and not pulled to that spot by the higher acceleration towards the center of the Earth. then we have to come to the difference between the pressures and the main thing is there's much more gravity on the far side of the Earth. I think you have to remember that the Earth is moving independently of the water that the Earth is spinning. I don't think that he should have gotten into the difference in gravity between front and back I think the point is to talk about why there are two peak depths some information if you wanted to go beyond that about the orbit of the moon. What I was studying the phenomenology of mathematical structures which was the title of the textbook I think it said didactic phenomenology of mathematical structures so you can Google that title it wasn't cheap back of an in hardback but the two professors the older one said that the authors were just showing off in the first chapter or the forward. I disagree, I think the authors were saying if you're not able to understand this chapter at then you shouldn't be trying to get into a mathematics classroom in other than a student's chair. be kind of selfish tree the professor was guilty of as accused would be what is causing a problem here instead. Maybe not.
But the final words of the professor about the scale of the power are absolutely Pro fossil fuel an anti renewable energy agenda is evidenced tragically. the professor however might be teachable but I've yet to see a single indication he's read a single comment
@@joseylastborn8790 I wont bother to read all of what you wrote since the first statement that was aimed at me is wrong, if you bothered to read the article you would have found out it does go over why there are 2 high tides, but also a very short summary of the suns effect on tides
To understand why there are deeper oceans on both sides of the Earth does not require visiting General discussion of the tides. You deserve a short simple clear sharable insight. SOON I promise.
222 - 8 = 214 not 216
"Air turbine" = windmill lol!
222 + 8 = 230 not 226.
Oh, yes, daddy, talk renewable energy to me :D
No stable base load
Philip fuck you and your ignoramus neuron Ness baseload nonsense he's talking about energy even if he glibly Mansions electricity for transparency at best reasons. Energy moron. Not electricity. Baseload concerns don't exist for Henry Ford assembly lines and competition requires the same for energy production. But of course you know that if you have a clue at all and are just some sort of snark some sort of whatever those goddamn term has that you have on the tip of your tongue but I don't know.
The reality is something I'm going to talk a little bit about when I finish getting through the 71 comments in moment
What?
The moon is 238,855 miles away.
How can such a brilliant tutor be so utterly wrong?
He’s not an astronomer and the lecture wasn’t about the moon, so I would imagine he used ballpark numbers without double checking them because he just needed some imprecise measurement for his explanation of the tide
Measured from the centers.?
Nah, nuclear is better
@@lucasprzybyla7084 why not zoidberg?
