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.

[@touristguy87]

"Water power, whether from a river or the ocean tides, is absolutely reliable, vs wind power or solar power. " a) not if the flow of water into the generator stops,or the generator fails, or the power-transfer system fails. b) in any case you'd want to use some kind of energy-storage system to supplement the direct supply

[@william6526]

The dams in rivers chánge the natural flow of the river so the lakes behind the dams heat up the standing water in the reservoirs that effect the ego system of the river and the reservoirs trap the silt which over time builds up .The water running over the spillways and thru the turbines cause the co2 in the water to climb that kills migrating salmon that are headed to the oceans in thier life cycle. The immature salmon are killed by the millions going thru the blades of the turbines or over the spillways of the dams. All the dams on the Columbia river has caused the once massive salmon runs to be a small fraction of what they were prior to the building of all the dams that block the river along its complete lenth of 120 miles from the ocean to the rivers beginning . They are a necessary evil that have caused huge ecological damage to the river an surrounding area. Most of these dams were built prior and during world war two to generate power for the manufacturer of aluminum for the war effort ​@touristguy87

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 only viable tidal electricity technology today is swedish Minestos tidal kite with 1,2MW 28 ton 12m wide turbine. It works even in slow currents while not one of the other tech. do that cost effectively. O2 2MW and 800 tons of steel is INSANITY. Waste and CO2 footprint off the charts.

[@ricomon35]

Waste form what? They don't use engines that can pollute. The platforms are pretty green in function

[@ScottSuhr-l8m]

Regarding the "kite" version: The gyroscopes used to orient the kite and control its motion need a system to calibrate it periodically or the inherent drift associated with gyroscopes (regardless of type or accuracy) will turn up to down and cause aberrant behavior or a crash into the seafloor.

It’s utter madness to use these renewable systems as the ONLY source of energy you have. But here in the UK we seem to be doing just that…

[@GruffSillyGoat]

Not just seem, indeed the UK has and will continue to do so; the last coal power plant closes the end of this month. However, I don't see why this is madness nor is reducing the dependency of Natural Gas that is imported at vast expense to everyone in the UK. The UK having a diversified mix of nuclear, air/wind/tidal rewnewables, geothermal, hydro and biomass to a level where it becomes a net exporter of electrical energy surely is the way to go. Moving our energy economy from a oil and gas exporting one to an electrical exporting one, creating high value jobs with it. Such will also finally remove the dependancy on gas power generation, which is now a minority power source but one that still dictates the price we all pay for our electricity. When this anomaly is closed the cost of electrical energy will drop to the cheaper level renewables and carbon zero sources enable. All round a win-win.

[@marksapollo]

@@GruffSillyGoat It's really VERY simple. The UK grid is NOT designed for renewables only, we have NO storage capacity for when the sun doesn't shine or wind blow or it blows too hard. So you are guaranteed for rolling regular blackouts, all for LESS then 2% of GLOBAL EMISSIONS. The economy will collapse, business won't exist, every other country in the world NOT be doing this will have a huge economic advantage. The experts have already stated NO ONE knows how much it will all cost to upgrade and install, but the National Grid already estimated to upgrade the entire network, so it we works, would cost about a trillion Sterling. Yeah that's why it is 'utter madness'.

[@GruffSillyGoat]

@@marksapollo - which experts, certainly not those actually at the National Grid (NG), who have a very detailed costed and funded plan for the upgrades. Not sure where you get the trillion pounds from the NG's own figures for the series of projects is £30bn spend now till 2029. BTW the upgrades relate to connectivity of new renewable sources, extending the reach of the grid and overcoming already existing congestion points in the UK's grid not an overhaul of the grid's core transmission capability. The reason why is that the UK grid was sized for 80GW as was used back in 2006, since then due to increasing efficiencies (such as the big impact on moving to LED lighting and industrial processes) the UK only uses 25 to 35GW of transmission capacity. The NG's own experts as well as independent industry experts all confirm the UK's grid is fully capable of supporting renewable and zero carbon generation sources. Regarding storage, it is incorrect to state the UK has *_"NO storage"_* rather the UK has 4.4GW of existing battery storage, an additional 4.3GW coming on stream this year and a pipeline plan for 95GW of battery storage by 2030. This is more than ample to address UK's needs, plus of course geothermal, hydro (sluice and dam) and nuclear are always on energy resources. In terms of aligning generation and usage timeframes this goes in hand with the battery storage. The geographic footprint of the UK ensures wind is blowing at some point in the UK nearly always, with only a 2 day UK sized lull occurring once every five years. Further the UK diversifies it's energy supply by sharing with our neighboring countries via HVDC lines, which thanks to the UK's location we have been a net exporter of energy in the last few years. These interconections are only increasing in number, with more going into Germany, Norway, Netherlands, France, Ireland and Belgium. Further afield there are plans to connect Shetland (which already has a HVDC connection to the mainland) to Iceland and a private enterprise connecting Cornwall to Morocco. So despite your gloom and doom prophesying, things are actually looking fairly good, on track and the UK is happily just getting on with moving to zero carbon energy generation basis in a calm and considered manner.

[@marksapollo]

@@GruffSillyGoat You are full of it, fact no storage facilities exist on the UK grid. Your claim there is is just as wrong as the rest of your thesis.

[@GruffSillyGoat]

@marksapollo - Wow, you really need to research harder, your claim that *_"no storage facilities exist on the UK grid"_* is so easily proven wrong. Numerous deployments have been installed and the pace has been ramping up since 2013, including: - the 50MWh utility scale battery installed and operational at the Pelham (Bishop's Stortford) site by Statera in 2017 that connects directly to the 132kV grid in the area. - the Tesla based grid connected battery that went live at Pillswood (nr. Hull) in 2022 that was Europe's biggest battery at the time at 196MWh; which also connects directly to the grid and acts to support the worlds largest offshore wind farm by mitigating curtailment. - Indeed the UK has a habit of installing the biggest grid connected batteries in Europe, as in 2020 the Minety site (in Wiltshire) went live with a 100MWh grid connected battery (now increased to 150MWh), which was installed and run by a division of Shell Energy. Yes, even giant petrochemical companies are in the game of installing and operating grid scale batteries. - and it doesn't stop there, only recently it was reported that construction had started on a massive 624MWh battery in the West Midlands, whose aim is to stablise the grid at the Cellarhead substation that supports a mix of industrial, commercial and residential use. Due for completion before the end of 2026; yes, it only takes a couple of years to install and switch this monster on. In summary, there are 98 utility scale battery storage sites operational in the UK currently (many co-located with solar and wind farms), 70 more under construction, a further 388 due to start construction and 400 more at the planning stage. So yes, I would say the UK has grid connected storage. This is the same for all the other points I raised, which are drawn from published facts and authoritative sources, including the National Grid themselves. So you may wish to exist in denial but the renewable electrification of the UK is a very real thing, that is very much happening as we converse. All this with the additional bonus of the UK creating a wealth of new highly skilled green jobs and level of expertise in designing and deploying renewables that is seeing UK companies (like those in this video) provide products and services worldwide; and, yes many other countries in the world are _"doing this"_ as in deploying renewables. So rather than collapsing the economy going green is growing it.

The indigenous people of Australia reverse engineered the wings of birds about forty thousand years ago. They applied that knowledge to the invention of the returning boomerang.

The returning boomerang is not unique to the Australian Aborigines, but was used in several other regions of the world before it was used by the Australian Aborigines. The Australian Aboriginal history, culture, and art, which is currently taught to primary school children, and promoted under the guise of the supposed 'truth-telling', are complete fabrications. The vast majority of people in Australia are being played by the Aboriginal activists who are highly manipulative and deceptive con artists. The Australian Aborigines were, and to a degree, still are, one of the most savage and violent people on earth - against fellow Aborigines. The victims of the Australian Aboriginal violent culture, were and still are, women and girls who were treated by the Australian Aboriginal men, as chattels. Polygamy was the norm, particularly by the Aboriginal elders who would be given 5+ girls aged 11-13 years at their inauguration as an elder. Violence against Aboriginal women at the hand of Aboriginal men, was evidenced by multiple scars particularly on their heads, which was widespread. It's no wonder that Aboriginal women preferred to marry white settlers. The colonisation of Australia by the British 🇬🇧 was the best thing that could ever have happened to the Australian Aborigines - it saved them from their savagery against fellow Aborigines.

[@benjamink1403]

[@thoriummarcell403]

Nuclear energy with breeder reactors (with Thorium or 238-U using material from spent-nuclear fuel as a kindof "catalyst" to keep the reactors operational) is the last great untapped energy source on Earth, that requires 100 times less resources and produces orders of magnitude less waste (including toxic waste and radioactive waste) and produces orders of magnitude more value in useful resources than any other "untapped" or tapped energy source (most of the fission products is valuable and useful, and for each GWyear energy very small amount of waste is produced, much less than other technologies).

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 ?

Actually, ocean surface waves have at least three orders of magnitude (1000 times as much kinetic energy) when offshore seas and swell are converted to plunging waves, on-demand, as need, in non-storm conditions. During storms, Wave Energy Conversion (WEC) devices can be lowered to optimal depth for continued operations.
