      Have you watched our new video on Real Science? When we posted it we only had 30k subscribers. Somehow it now has 1.4 million views. Madness

      1. Johnny boi Supreme

        No offense but I don't think the effect that industrial development has on property value is important when it comes to economics. Property values will fluctuate and the most efficient way to deal w/ those is simply to leave them alone so people may make their own choices.

      2. Ron Brideau

        @first name last name Probably easiest to think of it as the energy comes from the spin of the earth and gravity is rope tugging from ocean to moon

      3. CD3MC

        There is also a tidal power plant (Annapolis Royal Generation Station) in the Bay Of Fundy in NS, Canada.

      4. Jonathan Garzon

        Corrosion is far more an issue than you can imagine, this technology has been around for years now, has relatively non existent restrictions and has yet to be instituted by any large companies due to the break down of the turbine's being so constant. This doesn't even begin to address the inconsistent currents not to be confused with tides that are, unlike commonly believed by most people, not on a set schedule not direction. They follow large scale flow like the Atlantic jet streams but are hectic beyond belief. Liquid salt reactors are safer less costly to build and maintain per Kw/h and killl less animals not to mention produce less pollution. Thorium salt reactors in particular would allow for a massive advancement on cancer research as well. It's not PC though so most people will keep repeating "CHERNOBYL!!!!"

      5. P16

        Hi, I'm from India. Is there any job opportunity in Australia after doing any course you talk at the end of the videos?

    2. Spirit Beats

      The moon is drifting away and it won’t be reliable in the next few million years. However for a million years wave power could be great!!!

    3. Farming in Mexico

      Why not use the heat of the nuclear of the earth in unlimited energy and low maintenance and free!!

    4. clifton sheldon

      Are they going to transport electricity all the way to me in the middle of the country from the coasts ?

    5. John Lammi

      there is no energy problem now.

    6. Dylan Isaac

      Watch these get stolen XD

    7. wisconsindabber

      See that son that's a blended whale

    8. gadgetsage

      Yes, let's take energy out of the source of all life on our planet until the sea dies completely, fucking brilliant. If you don't understand that this is sarcasm, you might be dumb

    9. Trollinyamon

      It seems more and more clear that environmentalists wanna live in mud guys without heat or electricity.

    10. Nathan Frey

      Short answer: no

    11. Cypher

      Yay and we get some fresh cut up fish from giant fans. Huraay!

    12. Bernd Anders

      instead of shredding birds we are shredding sealife now lol

    13. Billy Mehaffey

      Why does NASA State the earth is flat and stationary in this PDF 5 separate times in summary sections ??

    14. Osiris Rex

      Wasn't this channel called Reel engineering? 🙄

    15. American Outside

      Yes and clean and forever for free.

    16. Larry MacDonald

      You throw away half the energy you produce... at least half if not more.... you should concentrate on using the energy you produce properly.... how many electric motors do you people run ?.... they all produce heat and you throw it away, air conditioners, fridges, dryers, commercial freezers all sources of heat energy you throw away.... Liquid cooled motors???? yep we got em, heat sink to transfer that heat, yep we got em.... producing electricity using steam.... yep we been doing that a long time..... take all that heat energy you throw away and use it to pre-heat water for steam genny's...

    17. John Coloe

      There is no silver bullet. Only silver buckshot. I've maintained for 30+ years that wave/tidal energy is a reliable renewable resource that, like solar and wind, should be tapped. Had we embarked upon research and development even 20 years ago, imagine the progress that could've been made; how much less fossil fuels would've been burned; the amount of greenhouse gas emissions avoided. Beyond environmental impacts, which are rather benign, the single greatest issue with wave/tidal is that of concentration. Yes, the majority of the world's populations live near coastlines. However, vast expanses of land and billions of people do live inland. So, the expense, environmental impacts and losses associated with long-distance energy transmission mandate diversification into additional means of renewable/sustainable energy generation. The single biggest error in U.S. and world energy policy has to be nuclear. Since the publication in 2006 of research into molten salt reactors conducted at Oak Ridge National Laboratory during the 1960's, the world has had a clear road map for "green" nuclear energy: • Worldwide elemental abundance (no more wars over oil) • Walk-away safe designs (no risk of meltdown, etc.) • Dramatically lower toxicity (a fraction of the waste of legacy designs, as well as shorter half lives [hundreds of years instead of many thousands]) • Low proliferation risk Best of all, these small, affordable molten salt reactor facilities can be built wherever needed and have much lower total costs of ownership than any similarly sized alternative.

    18. SUCH Developments

      Australia has Carnegie energy with up to 12m dia buoy filled with the seawater which moves with waves they sit 6m below the surface. The buoys drive power piston similar to that used by oil rig back to shore where goes through a turbine to generate power or the pressurised water is used in desalination plant to give fresh drinking water.

    19. Brian Mullinax

      We all know we are years away from this. In the meantime we are fools to ignore nuclear.

    20. Roger Woodruff

      first we were told plastic bags good, paper bags bad, they kill trees, now the liberal scientist say plastic bad no bags so we buy reusable bags same thing here, lets put water turbines in the ocean and see what happens

    21. İka

      Ah yes, let's tap into this wasted energy resource and kill out the essential and energetic underwater currents necessary for maintaining heat, and underwater ecosystems which are being used by actual living beings unlike us engineers all jokes aside just engineer a damn Dyson sphere already

    22. El Rolo

      This is disgusting! You are advocating more long term pollution of our world. The land has been littered with broken down rusted relics of wind turbines and strewn with plastic solar panels that after their useful life cycle, nobody is cleaning up due to costs. Now you are advocating more pollution ruining of our coastlines that energy companies will abandon once they take their profits out. I say stick to conventional tried and proven energy systems like hydro, nuclear, natural gas, clean coal.

    23. Son of Baconator

      I hope this is very successful! It could help save the planet along with solar and air👍

    24. Brian Bob

      this is going to be a huge expensive barnacle covered high maintinence mess.

    25. VenomStryker

      I hate the fact that good ideas never get off the ground because of something as petty as money.

    26. GeoFry3

      No, every 2-3 years this pops up and nothing has changed. Material science has still not come up with anything that can survive in an ocean environment for any meaningful, ie profitable, length of time.

    27. The1stHomosapien

      i hate his accent, its so shite.

    28. FaberOfWillAndMight

      Sounds incredibly inefficient.

    29. Robert Hernandez

      why is he hissing so much?

    30. CUBETechie

      What about the Wels turbine?

    31. Salciano

      I did a work on this around 10 years ago, for Portugal. I'm surprised to know how little seems to have changed...

    32. dj blake1215

      This needs to happen now,should have been sooner fuck the money spend it stop killing our planet we or we won't have one

    33. Jacob Opstad

      I would hardly call it "wasted energy." All that churning and flowing is part of the water cycle which helps to regulate weather around the earth. The more we tap into that cycle, the more unpredictable the effects will become. Still, it's obviously a better choice than what we have now.

    34. Walter Kurka

      How many fish, seals and whales where hit or killed by the unprotected blades. How can I get a copy of that report. I love this underwater via water chanel flows.

    35. Wiener Woods

      Maintenance is gonna kill this idea. I own a boat, and keeping the hull clean requires monthly scrubbing underwater. Then there's all the problems with keeping seawater out of the electrical system. The deeper you go, the more of a problem this becomes. There's also a huge problem with dissimilar metals, which will lead to severe corrosion and failure is not managed properly. Oh, and how are you gonna get the power produced back to shore effciently? Solar and geothermal power are the most economically and technologically viable "free" energy sources we have, and they are plenty. Look at how badly we've screwed up the planet with difficult to extract and refine fossil fuels. Unlimited energy would simply encourage irresponsible development and waste. What's needed is better management and development of existing energy sources, not hare-brained schemes for new unlimited sources.

    36. Apple apple

      Fuck like imagine going for a swim and something hits your foot

    37. eM Jay

      10:19 Hahaha

    38. jim parsit


    39. benign D

      I am so mad that nobody caught that personal massage at 13:26

    40. Pe Ka

      by extracting energy, we slow down the waters, do we not? Does this not massively affect the organisms living there?

      1. FaberOfWillAndMight

        No you would need to make the moon disappear to do that.

    41. Duggy Dugg

      the elite think there are too many of us... I agree ... they want to kill us I think attrition is the better plan than catastrophe

    42. Peter Sellers

      This topic makes me hungry for assorted turbine-diced fish.

    43. Lee Turnbull

      Geothermal energy is the best option, it is feasible in engineering terms, clean and pretty easy to do. Much less engineering involved than sea power

    44. Triadne Jessica

      i liked how there was a clear demarcation of the end of this video and a satisfying conclusion before your segue into your sponsor.

    45. Ron Lawson

      Environmentalist will be against this and it will have nothing to do with hurting the environment. If you want to succeed you must ignore them . You can not argue with leftists you should know that by now !

    46. Jerome Reyes

      Can humanity solve nature problems ?

    47. PB&J Racing • 13 years ago

      What about using a corkscrew design?

    48. rassooneggs

      Elon-chan must look into this

    49. SWOA Studios

      This is actually so cool! I really hope we can save this amazing planet with this product

    50. Robert Weekes

      Tidal energy is probably harder to do than wind. Just do advanced nuclear -see *thorium* molten salt reactor videos

    51. PULLUP J

      This videos title is so fucking dumb even the most basic brain of understand science can tell you yes. It’s call water energy. Now please figure it out. “Can a damn bring power to a city”😂😂 no shit

    52. Volksverarschung

    53. David Fraser

      30 minutes to remove. Yes theoretically. First you need to mob a vessel, transit, perform weather dependent lift, do the work and then reinstall. So 1 day. What is the frequency of maintenance. Large wind turbines have fleets of maintenance vessels. 3.5 years to pay for the installation, what is that when maintenance is considered. Always will be niche.

    54. Colin van der Voort

      Why are we not funding This shit!?!?!? Stop with the stupid windmills (that are a waste of mony and defile the view) and I m from thé netherlands for God sake!

    55. Sean O'Rourke

      We'll just have to see how many sea mammals get hit. I bet they thought birds would avoid the wind turbines too, but nope. They get slaughtered during migration every year.

    56. Afridi Hassan

      THankyou i have hope for it

    57. andrew Davis

      wave generators anywhere but where rich people live...Just the look of them would lower the value of their homes ?????

    58. weekok wong

      the issue of turbines is the issue of wear and tear that makes frequent maintenance a requirement. and not all locations are easy to harness energy as shown in videos as operations in deep sea will greatly increase time and cost even for transport of workers

    59. Hope Filled Sinner

      Hmm great idea, lets create a electrical energy system surrounded by salt water. Then we can produce sushimi with a high revolution propeller under the water at the same time. Asians can simply eat while Europeans could bbq on the sea shore collecting fish pieces with a net.

    60. rainwolf034

      You forgot the earths rotation in your tide explanation.. rivers are some of the most dependable energy..
