Can Underwater Turbines Solve Our Energy Problems?

  • Why Cant We Get Power From Waves?

    3:16

    Thanks to OIST for sponsoring this video. To learn more, visit
    Wave power hasn’t yet made a splash because it’s hard to use waves to spin turbines, and because the sea is a harsh place to build things.

    Thanks also to our Patreon patrons and our YouTube members.

    To learn more, start your googling with these keywords:
    Wave energy converter - a device for turning the mechanical energy of ocean waves into mechanical energy (flow of a substance) or electrical energy
    Oscillating water column - an open-bottomed chamber filled with air and water, whose wave action moves the water column up and down like a piston, forcing the air out past a turbine
    Attenuator - a long multisegment floating structure oriented parallel to the direction waves travel, where differing heights of waves along the length of the device flex the connections driving hydraulic pumps that can be connected to turbines
    Oscillating body - a floating buoy that oscillates with waves, generating electricity within the buoy or by pulling on a generator or by pumping water through a turbine
    Overtopping device - a reservoir filled by waves to a height higher the average nearby ocean, into which reservoir water is released, spinning a turbine
    Biofouling - undesirable growth of organisms like barnacles and algae on underwater surfaces
    Ocean wave - energy passing through water and causing it to move in a circular motion
    Turbine - a machine for producing continuous power in which a wheel with blades gets hit by a fast-moving flow of water, steam, gas, air, or other fluid, and spins (often connected to a magnet that spins)
    Induction - the production of an electric current in a wire by movement of a nearby magnetic field

  • Can Sea Water Desalination Save The World?

    13:29

    Today, one out of three people don’t have access to safe drinking water. And that’s the result of many things, but one of them is that 96.5% of that water is found in our oceans. It’s saturated with salt, and undrinkable. Most of the freshwater is locked away in glaciers or deep underground. Less than one percent of it is available to us. So why can’t we just take all that seawater, filter out the salt, and have a nearly unlimited supply of clean, drinkable water?

    Can Sea Water Desalination Save The World?

  • Wave Power into Electrical Energy | Turning the Constant Power of Waves into Electricity

    3:42

    Think of a renewable source of energy that could be harnessed constantly to produce electricity. I know, you guys must be thinking sun and wind. Am I right, although these are two very important sources but there is one source which is more reliable than them, and that is, wave power. Unlike other renewables, wave power is one of the most reliable energy sources on Earth, and can play a major role in the ongoing clean energy transition. And here in this video we will see how wave energy is converted into electrical energy.

    Special thanks to Eco Wave Power for the video and for the invention, for more information about wave energy, check their channel also:

The truth about wind turbines and how they are one of the most cost-effective, fastest growing and arguably underused sources of energy currently available to us. But when a wind turbine is not in operation -- meaning, getting them built and working out what to do to recycle them once they're taken down -- they do have an environmental impact. How bad are they and is there anything we can do to mitigate it?

  • How do solar panels work? - Richard Komp

    4:59

    View full lesson:

    The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy.

  • Marine underwater tide generator

    4:55

    Hello?
    We are the CEO of Marine Energy Co., Ltd., who is trying to produce a tide generator using marine algae.
    The existing underwater tidal generators are installed underwater in the whole of the power turbine of about 200 tons so that the waterproofing, civil engineering and construction cost of the turbine is excessively enforced, It has a disadvantage in that it can generate electricity only in one direction by forcibly inducing the underwater tide in one direction to fit the turbine generator and shortening the generation time of one day.
    We have completed the Korean patent registration (Patent No. 10-1691933) on the tidal generators with the following characteristics in order to improve the excessive facility cost and inefficient generation time.
    - bottom -
    1. By separating the rotating power unit from the water and the power generation facility from the water tower, it was possible to reduce the corrosion and maintenance cost due to the seawater generated by installing the power turbine as a whole in the water.
    2. Semi-submersible barges were installed on the waterfront in order to pay for the excessive facility cost of civil engineering and construction cost to install the power generation turbine.
    3. Power generation Turbine is a propeller type in which a generator is generated in only one direction that is artificially induced, It is made into an underwater rotating body by applying a spinning wheel to transform the underwater tide into rotational energy regardless of the direction of the algae. However, Since the purpose of the generator is to produce electricity, it is not a one-to-one generator, but a large number of generators are installed to prevent the power from being wasted.
    4. By utilizing the water facilities of the awards, it is possible to utilize it as a marine tourism facility by utilizing the water photovoltaic power generation, the water wind power generation, the water recreation facility, and the water ship stop, thereby inducing a secondary economic effect.
    5. Despite the strong currents, the rotating body in the water does not turn faster than the algae and has a strong force, thus reducing the threat of underwater life, Rather, the aquatic organisms have taken the role of artificial fishes so that they can move away from the threat of human capture. (Efficient: efficient in the order of sea area with small difference in tides)
    6. To prevent excessive plant site and environmental destruction of wind generators and solar power generation, By reducing the pollution of the thermal power generation and the risk of nuclear power generation, it is possible to produce eco-friendly new renewable energy such as infinite energy production by using the tidal force generated by the rotation.
    By registering the patent for the above purpose, the crisis caused by the decrease in order quantity of shipbuilders is overcome by the mass production of the water barge, The crisis caused by the decrease in competitiveness of steelmakers is overcome by the demand for steel materials used for tidal power generation, As a result of the decline in the cost of additional electricity production, Future Realization of eco-friendliness of environmentally friendly electric vehicles, inducing the generator of batteries used, I believe that we can solve this problem by putting this invention into practical use through economical effects such as job creation.
    The 4th industry, which is expected to consume huge amounts of electricity, will be devastated if it is not preceded by environmental pollution, and environmentally friendly generator is not preceded.
    Therefore, we will pursue commercialization by collaborating with your company or attracting investment.
    Do not be anxious about the risks of nuclear power plants due to the damage caused by earthquakes.
    Marine Energy's tidal generator is a pioneering company that creates a clean earth that human beings should inherit in the future by producing and using eco-friendly new and renewable energy installed anywhere in a country with sea or strong current river. Will be.
    Dream is the future that can be achieved by human beings who strive and challenge.
    Marine Energy is a dream company and the future.
    You too can become a partner to make dreams come true with marine energy.
    Challenge now.

    Marine Energy Co., Ltd will join together.
    We look forward to cooperating or investing in individuals or companies.

  • You wont believe this new Tidal Turbine! | Energy Live News

    38

    The Scottish Government has awarded £3.4 million to help build what is claimed will be the world’s most powerful floating tidal turbine.

    Scottish engineering company Orbital Marine Power will use the funding to deliver the next generation O2 2MW Floating Tidal Energy Turbine, which will be capable of powering more than 1,700 homes a year.

    The 72-metre long O2 will be built in Scotland and installed at the European Marine Energy Centre in Orkney.

    Its turbine rotors can be turned 360° to allow power to be extracted from both tidal directions, with the device manufactured by Scottish company Texo Group and key components delivered by Gray Fabrication using material from Liberty Steel.

    Scotland has an estimated one third of the UK’s tidal stream resources and two thirds of wave resources.

    Scottish Energy Minister Paul Wheelhouse said: “We believe tidal energy technology can not only play an important role in our own future energy system but it has substantial export potential and this fund will help move tidal technologies closer to commercial deployment.

    “However, the large scale rollout of both tidal and wave energy technologies has been harmed by the UK Government’s decision in 2016 to abandon its commitment to provide ring-fenced funding support.

    “UK ministers must act quickly to provide the revenue support this exciting and innovative sector requires to achieve its economic potential.”

  • Energy storage under pressure | Danielle Fong | TEDxCERN

    10:15

    This talk was given at a local TEDx event, produced independently of the TED Conferences. Most energy storage methods, including batteries, are expensive and difficult to scale. Danielle Fong saw the opportunity to reinvent a classic technology - compressed air - to solve hi-tech energy problems. She developed a method to improve the efficiency of compressed air as an energy storage medium that could radically reduce cost and complexity.

    BLOG:


    Cofounder and chief scientist of LightSail Energy, Danielle Fong was featured in Forbes’ 30 under 30 list of people who aren’t waiting to reinvent the world in 2012. Fong dropped out of junior high school at age 12 to attend Dalhousie University, then dropped out of Princeton University’s Plasma Physics Department to start LightSail Energy. The company develops a form of compressed air energy storage, called ‘regenerative air energy storage’, which may be the missing link in the plan to make the world’s electrical grid green.

    About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience.

  • Nuclear Power Plants Are Floating on Water…Wait What?

    4:25

    Both Russia and China are developing floating nuclear reactors. Although critics have dubbed it Chernobyl on ice, it might have many benefits.

    » Watch more Elements!

    Floating nuclear power plants are self-contained, low-capacity nuclear power reactors that are mass produced at shipbuilding facilities. They can be towed to ports or power towns that are experiencing power deficiencies.

    Russia is building a fleet of floating nuclear plants and China is reportedly starting to build a floating nuclear power station set to be seaworthy by 2021 to provide power for its artificial islands

    Nuclear power is one option to free humanity from our dependence on fossil fuels for energy.

    Unlike oil, coal, or gas, generating nuclear power emits no carbon dioxide, though it does create radioactive waste, some of which has to be stored securely for thousands of years.

    And unlike wind energy or solar energy, it can produce energy on demand. So a few countries are aggressively pursuing nuclear power, and some have even designed ships with reactors to serve as mobile power plants.

    So is this idea ingenious or a disaster waiting to happen? Learn more on this episode of Elements.

  • The MeyGen Tidal Power Project - Episode 1

    4:00

    In 2010, as part of the Pentland Firth and Orkney Waters leasing round, The Crown Estate awarded an agreement for lease to MeyGen Limited, granting the option to develop a tidal stream project of up to 398MW at an offshore site between Scotland’s northernmost coast and the island of Stroma, as shown in the map below.

    The 3.5km site covers some of the fastest flowing waters in the UK, just 2km from Scotland’s north-east tip. To the north of the site is the uninhabited island of Stroma, which creates a natural channel with the mainland to accelerate the millions of tonnes of water flowing between the North Sea and the Atlantic Ocean every day. This site was originally identified by Atlantis in 2007, following a global review of tidal resource which concluded that the high flows, medium water depths and proximity to the mainland rendered it a prime location for development.

    The MeyGen project is currently the largest planned tidal stream project in the world and is the only commercial multi-turbine array to have commenced construction.

    Tim Cornelius, chief executive of Simec Atlantis PLC (LON:SAE) say he is delighted by the recent record-breaking performance of the MeyGen tidal wave power project.

    Tidal power has now been de-risked, he tells Proactive, with the next step to scale up at the commercial level.

    That will see the number of turbines at MeyGen rise from 4 to up to 40 turbines with Cornelius now looking at ways to supply large industrial power users.

    The power -from-waste project at Uskmouth meanwhile has now reached a mini-tender of the conversion system with large scale industrial tests to follow.

    Financial close on £200mln of funding to fully convert the project is expected next year.

    A restructured deal for the GHR hydro portfolio in Scotland is also likely over the coming weeks, Cornelius adds.

  • How to power the world from clean renewable energy sources. It can be done!

    12:58

    This video explains how all electric cars can be powered from clean renewable energy sources. In fact not just electric cars - all our energy needs for the whole world could come from clean renewable energy sources.
    Clean renewable energy will be cheaper, create more jobs, and of course cleaner - which means a much healthier population.

    Solar and wind are both intermittent sources of energy, but over a larger region the wind is usually blowing somewhere, and an electrical grid system is an efficient way of sending the energy from where the wind is blowing to where the energy is needed. In the northern hemisphere electrical energy from solar can be sent north in the winter via the electrical grid. It can also be sent east or west from regions with surplus to regions that need to cope with peak demand.


    Balancing electrical supply and demand by transmitting it through the electrical grid is much more efficient than attempting to store it and use it where it is generated. However any surplus energy should always be used – to run processes that can be run intermittently, to be stored in some form for later use, by generating hydrogen, or even if that is simply to heat up the ground or water tanks used by ground sourced heat pumps when heating is required.




    The team based at Stanford University have calculated what might be the most efficient combination of clean and sustainable energy sources to ensure a reliable and stable electricity supply all year round, to supply the energy we need for all purposes by 2050.

    They have also calculated how much electrical energy we will need to generate using these clean renewable systems.


    The figures shown in these charts are from the spreadsheets provided by the team at Stanford University.

    You can pause the video in order to study the charts, or you can download the spreadsheets themselves to see the detailed data.



    For the USA: the pie chart shows the different proportions of the main clean and renewable energy sources for the most cost effective supply of energy for all purposes from clean and renewable sources.

    The total capacity, in mega Watts, for each type of system that needs to be built in order to allow for the intermittent generation that results from variable weather systems. Wind energy could provide half of the energy requirements for the US.
    Solar power could provide vastly more energy than the US needs, but only in the day time.

    The total capacity that we need in 2050 is quite a small proportion of the clean renewable energy systems that we could build. Clean and renewable energy need not be in short supply. Note the need to store heat energy for balancing load on the grid.

    The potential power that could be delivered is huge!


    But the actual power that needs to be delivered to the end users is much less.


    And the bar chart shows how much energy needs to be generated by each system.

    For Canada onshore wind and hydro electric can provide the biggest share of electricity

    Canada also has scope to generate large amounts of electricity from solar, but wind and hydro dominate in the winter. Hydro provides peak loads and stabilises the grid.

    For Mexico onshore wind is the most useful source of energy in spite of the huge amounts of solar energy that could be harvested

    .

    In Europe, for the UK, again wind is the most cost effective source of energy followed by solar panels. And offshore wind could provide far more power than the country needs. Grid stability is ensured by a balance of wind and solar energy.


    for France again most energy should come from wind power, with solar panels next. Solar has the potential to provide much greater amounts of energy, but it would need to be stored.

    for Germany a slightly larger proportion needs to come from wind, as winter nights become a problem if too much is invested in solar panels.

    for Norway hydroelectric power could be the main source of energy, with wind power making up most of the rest. Norway has the potential to capture far more offshore wind power than is actually needed.


    Australia needs to use a variety of clean energy sources in order to balance the grid, in spite of the huge potential for capturing solar energy.


    New Zealand also needs a balanced portfolio of energy sources in order to balance the grid. With wind and solar providing the largest contributions.

    China needs a similar balance of wind and solar, in spite of the huge capacity to capture solar energy.

    for Japan again we see that a balanced portfolio of energy sources is needed with wind and solar between them providing most of the energy needed

    Thailand is not a windy country, but offshore wind can still make an important contribution to stability of supply. It has the capacity to capture far more energy from solar than it needs, but would need to store energy for night time use for heating and cooling. As well as night time electrical supply
