Tidal Power: Unlocking the Greatest Untapped Energy Resource on the Planet | FD Engineering

[@pcbasics1]

Back in 1979 I was an engineering student at the University of Illinois in Chicago, and as a senior year project I had to come up with some innovative engineering idea and design. I was very much amazed and surprised that I had come up with precisely the same idea, an underwater power generating turbine that used underwater oceanic currents to generate electricity. In addition to the theoretical hydrodynamics calculations substantiating the conceptual design, I also made conceptual drawings resembling machinery shown in the documentary! Unfortunately my professor shot it down as he believed it was not feasible!! I can’t describe how I felt when I saw my 40+ years old ideas converted into reality in this show!! My compliments!

[@donscheid97]

Interesting to think of how the Earth uses Solar and Lunar energy every day, from plant growth and thus wildlife, to climate, which again leads back to life. With that in mind, it is theoretically possible to have life on any planet anywhere.

@@donscheid97 The Earth *is* powered by the sun almost completely from the biosphere to the weather systems. The sun is 99.9% the mass of the solar system and provides us with a cosmic 173,000 terawatts of power non-stop continuous for billions of years at least a billion more. All the combined nuclear and fossil fuels would amount to a bucket floating in a sea by comparison. The sun's energy flows through our veins and powers our thoughts even as we ponder this.

In 1980, I worked at McNary Dam as a welder relining the turbine blades in the generator vaults, ( The river runs thru them ). The dam is rated at 1.1 MW. The Columbia River never stopped flowing 24/7. Water power, whether from a river or the ocean tides, is absolutely reliable, vs wind power or solar power. This concept of submerging the power turbines underwater is the critical breakthrough needed to make this type of power generation feasible, practical, and cost-effective. As a bonus, most ocean going cargo ships can safely pass over them. It is also great that they are not spoiling the ocean views, unlike wind turbines. And they do not need thousands of acres of land, unlike solar panel farms. It's a win, win, win.

Does not fit the economic model, be it communism or capitalism. There are many free energy sources available, all patented and copyrighted and shelved so no further development is possible. There is enough energy freely available for ten times our earth population, and then some. But if everyone or every community generates it’s own energy, then central control becomes obsolete. Remember before electricity that was exactly what happened, and that was less then 200 years ago.

Because interfering with the tides by putting harvester propellers underwater is exerting a force against the Moon and bringing it closer and closer to Earth. Consider the pachinko machines: all the pachinko parlours in the world are illuminated with electric lights (even though the machines themselves are hand-powered, to flip the balls.) If all the roughly 13,000 pachinko parlours in the world have an average of, say, 750 kilowatts of electric lights and air conditioning, that would come to thirteen million horses pulling the Moon toward the Earth. Slowly, slowly, spiralling in, that could be the end of us all in 4,177,934,427 years. And between eight and nine months! That's within a few hundred million years of the time there has been life on Earth. Plus or minus eight or nine months. And pachinko parlours are not the only thing consuming electricity. I forgot about all the other stuff. Oops. Be careful what you wish for. Also don't play pachinko.

To get to the beach, we rode a small, very small ferry, a man and a row boat across the tidal entrance to Christchurch harbour. The journey across the narrow channel was amazing because of the sheer volume of water that flowed in and out as the harbour filled and emptied with each tide.

In fact, after the sun goes, the earth will too and therefore nothing about this planet is renewable. Now if we're talking about reasonable lifespan rather than the most pedantic definition, nuclear will last us for 4 billion years because it's so energy dense and there's so much radioactive material on our planet to fuel it.

Some of my more noteworthy climate solutions. Instead of filling the basements, of demolished suburban homes, with sand; making a greenhouse basement topper, so creating 4-season earth sheltered greenhouses, to produce local fresh produce. I also came up with the idea to use surplus energy to pyrolysize cellulosic feedstock, with biochar dump loads, and route the synth gas to throttle-able thermodynamic plants. then the process storage is more economical……much more economical than grid scale battery storage. I also did my own local wind survey, and came up with Racine, WI- to- Burns Harbor, IN- offshore wind line as the best return on wind investment, in the midwest. Another idea I had was sitting cold bore geothermal with utility scale solar thermal. because cold bore geothermal is much more prone to success, and could utilize the same power generation equipment. and yet another idea I came with was building a continuous electrical conductor extrusion plant, up by the bearing strait, and using ships to tow a wire around the planet north-south, to harness the deformation in the earths magnetic field, which is caused by the solar wind. ------------- but a long the way, i realized the climate instability was more dominantly caused by loss of planetary carbon sink. a decade later I had the only real solution to the climate instability. but we can't get around african heroin's control over the planet.....so we are all going to die ?

Bigger is never better. Increasing size in view of diminishing returns is loco. Smaller, more agile distributed systems are more accessible, reliable and manageable on a human scale. That's important. The power class would rather not give up control and the advantages control brings. Distributed energy systems don't need herculean might in the same way larger, more centralized generation systems require. The problem capitalists have with distributed systems is that they're more difficult to leverage centrally, to seize control & profits from the hands of the locals. The internet enjoys multiple optional pathways to deliver communications. uses multiple works is only sustainable as a centralized system.

[@bradatherton9369]

Bold claims and blanket statements mean you're speaking from an armchair engineer's perspective. Comparing power distribution to internet is very flawed. I agree that a decentralized approach has its benefits. But when it comes to cost and feasibility, there is no truth in saying bigger or smaller is always / never better. Talk to the designers, withhold your claims, and you might learn something.

I have been banging on about tidal power for years. 1 cubic metre of water weighs a ton. We have some of the highest tidal range in the world. Tidal power is clean, cheap and way more reliable than wind. Why oh why do our politicians overlook it

I like the idea of geothermal too. Oh wait, nuclear fusion is just around the corner.

This is a very good summary and well put together but a bit out of date. Poor Sustainable Marine Energy in the Bay of Fundy has gone bust citing their inability to satisfy the Marine Authorities in Canada about the impact on fisheries. Orbital have deployed their O2 in the Pentland Firth and have announced plans to build several more in Scotland and even to try to go to the Bay of Fundy! Minesto have deployed their bigger machine in the Faroes already. Progress is being made all the time.

[@ianwilliams7740]

Would be very interested in the price per megawatt for these huge steel machines, especially when you add the constant maintenance costs and repairs associated with operating in such an environment.

[@WilliamBunch-z9s]

The main problem is these tidal streams carry nutrients and thousands of other things humans don't even know about from one place to another. There is a reason these streams travel the way they do. The wildlife impacts could be horrible and you would not know about it for 10+ years and then it is too late.

Sure bud. Name two species that might be impacted, and how. Because I don't think you're at all concerned about the environment and just phsihing for plausible ways to continue your politically indoctrinated opposition to anything other than oil, coal and gas.

[@bradatherton9369]

Your point about the nutrients is valid. But taken out of context considering how HUGE the ocean is and what a TINY percentage of disturbance this installation will be. Also, your comment about 10 years and too late is purely speculative and is dramatic without supporting evidence. So I join the other guy in sensing your remarks are more traceable to indoctrination than anything else.

[@gacherumburu9958]

👍👍 good info!

[@Jonasz314]

They built one tidal energy plant in France, as the documentary highlighted it was very expensive to build and they never reconducted the experiment. The idea looks really cool, but I'll believe it when I see it run for several years without a hitch. I really question the longevity of each turbine - if they have to be maintained too frequenty, economically it stops making sense.

[@SIC-SEMPER-TYRANNIS]

The Chesapeake Bay Bridge Tunnel should be a huge power producer, with simple tidal flow turbines installed, that would reverse rotate with the tides.

[@gormauslander]

It's amazing the orkney islands are still there after all that wear

[@MasterOvPuppetz]

nice idea, but what happens when we block those tides? ever wondered how fragile and tide/wind-dependant our general climate is?

It’s a cyclical event that cannot be stopped no matter what you think or do, I always spoke out regarding the massive amount of energy that could be produced from the tidal flow utilizing the rise and fall and the massive currents

[@markramsell454]

Good luck. Let's see what this stuff looks like in a couple of years in the salt water. Observe a boat that's in dry dock and you'll see what I mean. Sure the blades are made of composites but the fasteners aren't. That last design involves a moving tether. We need to make a pool on when that will fail, somebody could win big.

[@greglaroche1753]

This is a very interesting approach to supplying energy. However, nothing has been about how they intend to deal with marine growth.

[@Farwalker2u]

I have been seeing projects proposed for the last fifty years that have ideas to use water energy to generate electricity. One used two floating platforms which had either hydraulic or mechanical bears to make the moving platforms moving on the waves generate mechanical energy in to electrical power. Another was a hydraulic screw (propeller) that would be submerged into a large river and would turn because of the flow of the river's current. This would then generate electrical power. Another was tidal flow much like the river flow. Unfortunately, everything man made that moves eventually breaks. The long term (10 years or more) feasibility of these projects tend to fail because they cost more than the existing generation of electrical power.

[@deborahduthie4519]

Nuclear Power was useful but we have always wanted a perpetual source of Power Generation. Water, Solar and Wind serve us Earthlings better. Here's to a Clean Future

no, all those sources require more materials producing far more pollution than nuclear reactor and building construction when account for every material used in the complete life cycle

[@EliteRock]

What needs to be borne in mind is that the power produced by these machines is "green" or "sustainable" only after they've generated the power used in manufacturing and maintaining them. Finding breakdowns of these numbers seems to be impossible. My suspicion is that they barely repay that energy debt, if at all (IOW they are NOT 'green') and their usefulness is in their portability and being able to move power generation capacity to remote areas where, for whatever reason, extending the grid is impractical (I don't actually see what impracticalities those would be - ETA >> cables can be laid practically anywhere).
