The Endless Power of the Ocean

Think about it, the ocean is moving 24/7/365. Between the waves and the tides, there is a constant source of renewable energy being generated, but not being harvested.  “Generating technologies for deriving electrical power from the ocean include tidal power, wave power, ocean thermal energy conversion (OTEC), ocean currents, ocean winds and salinity gradients.

 

 

Of these, the three most well-developed technologies are tidal power, wave power and ocean thermal energy conversion. Tidal power requires large tidal differences which, in the U.S., occur only in Maine and Alaska. Ocean thermal energy conversion is limited to tropical regions, such as Hawaii, and to a portion of the Atlantic coast. Wave energy has a more general application, with potential along the California coast. The western coastline has the highest wave potential in the U.S.; in California, the greatest potential is along the northern coast.

 

 

California has more than 1,200 kilometers (745 miles) of coastline, and the combined average annual deep water wave power flux is over 37,000 megawatts (MW) of which an upper limit of about 20 percent could be converted into electricity. This is sufficient for about 23 percent of California’s current electricity consumption. However, economics, environmental impacts, land-use and grid interconnection constraints will likely impose further limits to how much of the resource can be extracted.

 

Although technology is still at a relatively immature pilot project stage, economic projections indicate that ocean energy could become cost-competitive over the long-term.”

Good News About Clean Ocean Energy

What the heck is OTEC?

SM Beach N.While it may sound like the precursor to yet another huge oil company, nothing could be further from the truth. OTEC stands for Ocean Thermal Energy Conversion, which is generated using the difference between the warm surface water and cold deep water of the ocean. The temperature difference can be used to drive a steam cycle that turns a turbine which in turn produces power. When the warm surface sea water passes through a heat exchanger, it vaporizes at a low boiling point which is then funneled into a turbine generator, producing electricity.

Di at Cafe Culture2I used OTEC as the futuristic renewable energy featured in my sci-fi novel “Anti-Vigilante and the Rips in Time”, but I sure hope it won’t take centuries to see it become a viable energy source!

The World Water Wars (Anti-Vigilante and The Rips in Time)

Anti VigilanteI’ve written an unusual science fiction novel “Anti-Vigilante and The Rips in Time”.  Creating my own world, peoples and language, the book is a “preventable vision of the future” with its hooks deep into renewable energy and the impending World Water Wars.  The science in my book utilizes ocean energy and photovoltaics to power their daily world. People from the past become the Gods of the Future as they appear through the Rips in Time.

You can find “Anti-Vigilante and the Rips in Time” at Amazon.com today, just follow this link: http://www.amazon.com/Anti-Vigilante-Rips-Time-Diane-Tegarden/dp/0974536911/ref=sr_1_2?s=books&ie=UTF8&qid=1350751953&sr=1-2&keywords=Anti-Vigilante

World Water Wars…have they already begun?

Oceans of Water everywhere, but...To highlight the growing concern over the scarcity of clean water and the need to use renewable energies, Vince Beazel and I will be discussing “Anti-Vigilante and The Rips in Time”, a science fiction novel set in the distant future with its hooks deep into renewable energy and the changing face of the planet.

In my novel, the last War on planet Earth (Terrax) was called “The World Water Wars”. In the last three years, while collecting research for my novel, I’ve documented the increase in violent conflicts worldwide over water.

The World Water Wars vs. OTEC the Wave of our Energy Future

What is OTEC?

 

OTEC is an acronym that stands for Ocean Thermal Energy Conversion, which is energy that is generated using the gradient (or difference in temperature) between the ocean’s depths and its surface.

 

There are three types of OTEC, one of them being the open cycle system. The Ocean Energy Council explains how it works as such:

 

“Open-cycle systems convert warm surface waters into steam in a partial vacuum, and then use this steam to drive a turbine connected to an electrical generator. Cold water piped up from deep below the ocean’s surface condenses the steam. Unlike the initial ocean water, the condensed steam is desalinated (free of salt) and may be used for drinking or irrigation”. (2)

 

The oceans cover 70 percent of the Earth’s surface, making them the largest repository of unconverted energy in the world. Using the natural ocean temperature variations, either in a coastal plant or using plantships, energy can be generated and used to power homes and businesses.

 

Imagine harnessing the ocean’s power!

 

“On an average day, 60 million square kilometers (23 million square miles) of tropical seas absorb an amount of solar radiation equal in heat content to about 250 billion barrels of oil. If less than one-tenth of one percent of this stored solar energy could be converted into electric power, it would supply more than 20 times the total amount of electricity consumed in the United States on any given day,” reports the Solar Energy Research Institute’s paper Ocean Thermal Energy Conversion: An Overview, published in November 1989. (1)

 

OTEC plants can: generate clean, renewable electricity, desalinate water and create a lively mariculture where the plants are installed along the coast.

 

According to the Ocean Energy Council’s website, “The largest (OTEC facility) so far is near Japan, and it can create 100 kilowatts of electricity. Another small-scale OTEC is off the coast of Hawaii, producing 50 kilowatts of electricity.” (2)

 

Not only is this form of technology available at this time (it’s not science fiction), there are several sites worldwide capable of utilizing this clean, renewable energy. The initial costs to install these plants are enormous (as are installing coal power plants or nuclear power plants), so governments usually step in to subsidize these types of  projects, which would create new jobs along coastal areas and infuse our overloaded energy grid with new sources of power.

 

Water shortages may very well be the cause of the next great World (Water) War, or it can be the wave of future energy generation.
