Harnessing Power from the Ocean's Tides, Currents, Waves, and Temperatures

I've always been an advocate of keeping-it-local with regards to politics and energy production. Growing up in a beach community, I've always been interested in this type of technology for energy production. It just seemed obvious to me for coastal cities to try to harness the ocean's energy. Is this the future of energy production? These seem like pretty basic concepts. What's the hold up? What are the downsides? Which method of collection below do you think holds the most potential?

Reading the excerpt below and keeping it in mind what this means if its true, question:

What is the likely amount of coverage the wholly owned corporate media will give this? On a scale of 1 to 10 - where 1 is no coverage at all, and 10 is breathless headlines about the future of mankind.

The enemy is anyone who would try to suppress or stop something like this.

"BlackLight has produced millions of watts of power in a volume that is one ten thousandths of a liter corresponding to a power density of over an astonishing 100 billion watts per liter.

BlackLight’s nonpolluting power-producing SF-CIHT cell catalytically converts H2O-based solid fuel directly into brilliant light-emitting plasma power, an essentially fully ionized gaseous physical state of the fuel comprising essentially positive ions and free electrons.

The SF-CIHT cell plasma is the same temperature as the Sun emitting the same solar spectrum of light, but at extraordinary power equivalent to 50,000 times the Sun’s intensity at the Earth’s surface. Optical power is converted directly into electricity using photovoltaic cells (solar cells).

Very high-power, high-efficiency cells are commercially available convert the SF-CIHT cell optical power directly into electricity at its 100 billion watts per liter power density. Patents are filed worldwide.

Fusion Energy Will Be The Ultimate Game Changer...

Mark February 12, 2014 as a day in the course of human events that will go down in history. A little less than 2 months ago scientists at the Nuclear Ignition Facility (NIF) at the Lawrence Livermore National Laboratory in California reported a long awaited breakthrough in the development of thermonuclear fusion energy. The NIF focused 192 laser beams on a tiny pellet of fusion fuel composed of hydrogen isotopes tritium and deuterium derived from water and released more energy than it consumed. This changes everything and paves the way for cheap, unlimited and non-polluting energy that will eventually render petroleum, coal, hydro, wind and solar energy producing technologies as obsolete as buggy whips.

I wonder

What that would do to the Petrodollar...

Great question....

I reckon petrodollars would be a thing of the past, but oils well that ends well.

Energy sources are plentiful, the catch is oil and gas are

cheaper, at least for now so the market chooses the less expensive. In addition to the above energy sources, what ever happened to geothermal? I know in some Midwest states they are building steam electric generators from deep oil/gas wells that are in "hot rock" formations and they are generating more energy than the original oil/gas wells that were there.

Another promising energy source is the GMO bio-fuels, like Joule energy have developed. When this technology was announced it was referred to a game changer in transportation fuels. Whenever these new ideas are introduced you never again hear about them, it does seem like they are being repressed.

Hemp is another promising source, not only for energy, but plastics, fertilizers and building materials. That I know is being suppressed.

Here are the reasons why this technology isn't developed

1) Potential energy: This comes from water height. It is the principle behind hydroelectric dam on rivers, and also most tidal generation facilities. There aren't many places on earth with significant tidal heights. Many places that do have enough height are already developed and generating power. The vast majority of earth has tidal height change too small to generate enough power to make it worthwhile.

2) Thermal energy: This is the power that can be generated from a temperature difference between a heat source and sink. The maximum possible efficiency is directly proportional to the temperature difference between the heat source and sink. This is the principle behind most of the power generated in the world, including from coal, natural gas, nuclear, and geothermal. The problem with ocean thermal is the temperature difference is too small, resulting in a maximum efficiency far too low to be useful.

3) Kinetic energy: This is the power that can be generated from the velocity of a moving fluid or gas, and is the basis for wind power. It is also the basis for stream power and some tidal power schemes. The underwater turbines have similar designs as wind turbines, only smaller. The problem is the maximum power is strongly dependent on the area of fluid that the turbine captures (ever notice how big wind farm turbines are?). Small underwater turbines can only generate small amounts of power, and they have the added complexity of being underwater (corrosive environment, and difficult to install and maintain).

I wouldn't invest in any of these schemes, or drop any money into kickstarter projects. I'm sure some people will jump on me claiming technology is all being suppressed by big oil companies, or other such nonsense. The reality is that there are fundamental laws of thermodynamics that make all of these schemes expensive and impractical.

We all want progress, but if you're on the wrong road, progress means doing an about-turn and walking back to the right road; in that case, the man who turns back soonest is the most progressive.

-C. S. Lewis

Isn't developed?

I don't question the points you brought up, as they are good points which regularly come up. However, I don't think these are scams and a few of them are already developed producing energy in real life or under construction. I don't think these technologies are being suppressed, but rather, I feel like other energy prices are kept artificially lower than they would be without government intervention, thus skewing energy markets.

OTEC International LLC, Hawaii Project at Kahe Point is privately funded and in the process of building a pilot plant.

According to the U.S. Department of Energy, OTEC was ready for development almost 30 years ago. The oil crisis of the 1970s spurred OTEC R&D, but when the price of oil sharply declined, so did OTEC’s political and financial support. OTEC energy could not compete with cheap fossil fuels. Now, as oil prices rise due to growing demand, and the manufacturing technologies to produce affordable OTEC system components have been commercialized, OTEC has again surfaced as a promising source of energy.

There are several tidal power plants around the world:

- Rance Tidal Power Station built from 1960 to 1966 has 240 MW installed capacity.
- Sihwa Lake Tidal Power Plant in South Korea was completed in 2011 and produces 254 MW.
- Annapolis Royal Generating Station opened in 1984 and has 20 MW installed capacity.
- Jiangxia Tidal Power Station in China has been operational since 1985, with current installed capacity of 3.2 MW
- Race Rocks Tidal Power Demonstration Project was installed in 2006
- Project by Soviet Union at Kislaya Guba on the Barents Sea has 0.4 MW installed capacity.
- Jindo Uldolmok Tidal Power Plant in South Korea planned to be expanded to 90 MW by 2013, was installed in 2009.
- A 1.2 MW SeaGen system became operational in late 2008 on Strangford Lough in Northern Ireland.
- The contract for an 812 MW tidal barrage near Ganghwa Island (South Korea) is planned for 2015.
- A 1,320 MW barrage built around islands west of Incheon is proposed by the South Korean government, with projected construction starting in 2017.[22]
- The Scottish Government has approved plans for a 10MW array of tidal stream generators near Islay, Scotland, costing 40 million pounds, and consisting of 10 turbines – enough to power over 5,000 homes. The first turbine is expected to be in operation by 2013.
- The Indian state of Gujarat is planning to host South Asia's first commercial-scale tidal power station. The company Atlantis Resources planned to install a 50MW tidal farm in the Gulf of Kutch on India's west coast, with construction starting early in 2012.
- Ocean Renewable Power Corporation was the first company to deliver tidal power to the US grid in September, 2012 when its pilot TidGen system was successfully deployed in Cobscook Bay, near Eastport.[25]
- In New York City, 30 tidal turbines will be installed by Verdant Power in the East River by 2015 with a capacity of 1.05MW.
- Construction of a 240 MW tidal power plant in the city of Swansea in the UK, estimated to begin in Spring 2015. Once completed, it will generate over 400GWh of electricity per year, enough to power roughly 121,000 homes. Completion is scheduled for 2017, and the project has a projected 120 year lifespan.

I think the problem these technologies are up against has something to do with the petrodollar and cheap oil. As I mentioned below, I'm torn between conspiracy and this.

Do you believe oil prices are lower/higher/the same as they would be in a completely free market without the backing of the U.S. Military? I think they would be higher. In that world, this technology would be more prominent in my opinion.

I recently stood on a beach and . . .

watched the waves roll in. At one point there was a strong wind; there had been a thunderstorm, and when the heavy rain stopped I went back out to the beach and watched the high waves.

(No hurricane warnings)

I kept thinking, "There is so much raw power here; why can't this be harnassed somehow?"

Thank you for posting this.

it's hard to be awake; it's easier to dream--

They dont want it

The elite (ie central banking families and friends) that architected the current system con-game that funneled all the real assets and ultimate control over governments and war into their pockets have other plans for "their" planet.

So any real plans like these that would benefit humanity are left out to dry. They're not interested in anything like that - so they order their media to pretend it doesn't exist.

Why blanket the earth with constant fearmongering about manmade climate change regardless of the evidence - while simultaneously (same people: 'majority stockholders' and all) developing and funding a genetic takeover of life on the planet that might end up wiping out huge portions of it .. including themselves.

Trying to get ahead of these kinds of plans by making sense out them in any real terms that we can relate to - well, it might be futile to any of us 'normals' who have the (primitive, 'quaint') ability to put naturally ourselves in other peoples shoes and care what happens to anyone other than ourselves.

The assumed rulers of this planet are insane. Massively intelligent, with pretensions of godhood - but their utter lack of a human heart and soul makes them blind and dumb to consequence.

Their defect will eventually be their undoing.

In the meantime, sane proposals such as using the earths natural motions to generate power are going to be hellishly slow to catch on. They've got way too much time and energy put into getting everyone looking in the wrong directions to give up now.

Nope.

Energy is to a great extent fungible. The "Elite" or anybody else trying to stop a cheaper, cleaner method of producing energy would be impossible.

Cheaper and cleaner is tough.

Individual self interest will win out over organized attempts to suppress.

Yes a bottom up revolution is the only way. I was answering the question posed by the OP - thats why imo.

The war is against anyone who would try to suppress or stop something like this - and they own the mainstream "press".

Well, the real free market

Is ultimately more powerful than anything or anyone that tries to stop it (human desire, human action etc).

The perpetual war between those who deign to try and control everything vs everyone else taking spontaneous and unpredictable action - choosing what they want.

It just takes a long time to play out.
