Plan ModeledPlan sets the US as a leader in OTEC developed – Gets modeled globallyMoore 2006 [Bill, citing Dr. Hans Krock, founder of OCEES, April 12, "OTEC Resurfaces", http://www.evworld.com/article.cfm?storyid=1008] "The United States is the best placed of any country in the world to do this," he contends. "The United States is the only country in the world of any size whose budget for its navy is bigger than the budget for its army." ¶ It's his contention that this will enable America to assume a leadership position in OTEC technology, allowing it to deploy plants in the Atlantic, Caribbean and Pacific, but he offers a warming.¶ "If we are stupid enough not to take advantage of this, well then this will be China's century and not the American century."¶ Krock is currently negotiating with the U.S. Navy to deploy first working OTEC plant offshore of a British-controlled island in the Indian Ocean -- most likely Diego Garcia though he wouldn't confirm this for security purposes.¶ He is also working with firms in Britain and Netherlands and will be headed to China for talks with the government in Beijing.¶ "The Chinese know very well that they cannot build there futures on oil," he stated, noting that China's is investing large sums of money in a blue water navy. "The United States will be playing catch-up in this technology. We're here. We're willing to do it. We're doing it with the Navy." He expects to put his first plant to sea sometime in 2008 after constructing it, mostly likely, in Singapore.¶ "We simply have to look at the all the alternatives [to conventional fossil fuels and nuclear power] and this is, hands down, the only alternative that's big enough to replace oil." A2: OTEC Harms EnvironmentOTEC doesn’t hurt the environment – water output offsets harm to marine lifeDworsky 6 [Rick, Member of environmental conservation and energy issues board for over 30 years in government and private industry. “A Warm Bath of Energy -- Ocean Thermal Energy Conversion,” The Oildrum, June 5 http://www.theoildrum.com/story/2006/6/5/171056/6460] At this time OTEC appears to offer an environmentally neutral energy source. The intermittent injection of minimal amounts of chlorine to prevent bio-fouling of the warm water intakes, and the leaching of metal particles and other materials via erosion/corrosion would probably be environmentally insignificant. Large storage tanks for chlorine would not be necessary - small amounts could be generated 'live' as required to manage the danger to personnel. No bio-fouling within the cold water intake tube has occurred. Although a 100% kill rate for small organisms such as phytoplankton that get drawn into the warm water intakes is probably inevitable, it is believed that this can be mitigated by the pumped 'upwelling' of cold deep fertile waters and the outfall effluent. Only extensive monitoring of an installed mid-size test facility can enable a comprehensive environmental assessment, and find the balance point between bloom and bust. Adjustments of the outfall depth may be necessary, according to local conditions. It may well be the case that OTEC can target some of the energy that causes damaging and catastrophic storms and redirect it into useful work, if large mobile floating platforms become a reality. We should carefully consider when a location can host the process and remain within it's normal temperature gradient range, this would be similar to concerns about the energy absorption effects of solar panels and windmills. OTEC appears to be a vast, renewable, sustainable, safe, 'always on' energy source that does not emit CO2 or nuclear waste. OTEC Plants are clean and don’t damage the environmentCross 2013 [Martin, Translator, former chef and marketeer, currently disabled. I write articles on food,, travel, politics, religion and technology. How an ocean thermal energy conversion (OTEC) plant works https://suite.io/martin-cross/67sw266 OTEC technology has the potential to produce vast amounts of zero-carbon electrical power. The potential hydrogen production could completely replace all fossil fuel consumption with the exception of lubricants. The technology even makes it feasible to mine the sea for minerals and metals. Reduction of costs is still a concern but the technology is effectively still in its infancy and, as with all currently used technologies, ongoing research and experience will produce advances that will reduce costs considerably. The advantages of OTEC technology are that the power source is constantly available, essentially inexhaustible, creates no significant pollution, provides significant useful by-products, is relatively easy to maintain and has a long service life with no inconvenient waste products such as ash, clinker or nuclear waste, requiring disposal or specialized storage. Plants can be land-based, offshore (similar to oil platforms) or even floating. A2: Solar Fails/Solar Bad/Etc.OTEC distinct from solarChoi, 8 - Date: 12 December 2008 The Energy Debates: Ocean Thermal Energy Conversion http://www.livescience.com/3155-energy-debates-ocean-thermal-energy-conversion.html Ocean thermal energy conversion relies on the fact that water near the surface is heated by sunlight while seawater deep in the dark is much colder. OTEC plants use warm surface water to heat ammonia or some other fluid that boils at a low temperature. The resulting gas is used to drive turbines that produce electricity. The gas is then cooled by cold water pumped up from the ocean depths and the resulting fluid is recycled to help generate power.¶ As OTEC relies on temperature differences, it works best in the tropics, where the surface water is hottest. As long as the temperature of surface water and the deep water differs by roughly 36 degrees Fahrenheit (20 degrees Celsius), an OTEC system can generate significant amounts of power.¶ The idea for ocean thermal energy conversion was originally proposed in 1881 by French physicist Jacques-Arsene d'Arsonval. The first OTEC plant was later built in Cuba in 1930 and produced 22 kilowatts of power, enough to supply roughly two typical modern households. Although a handful of OTEC plants were created following the oil crisis of the 1970s, funding for them dwindled after the price of oil dropped, and none are now operating.¶ Still, rising fuel costs have revived interest in these devices. In September the U.S. Department of Energy awarded its first grant for OTEC in years.¶ Pros¶ If less than one-tenth of 1 percent of all the solar energy trapped in the oceans could be converted into electric power , it would supply more than 20 times the total electricity the United States consumes everyday, according to the National Renewable Energy Laboratory. "It could easily supply all the energy we wanted," said Terry Penney, a lab program manager at the National Renewable Energy Laboratory in Golden, Colo. "The process is very low efficiency, just 2 or 3 or 4 percent, but all that energy's free."¶ Unlike wind and solar power, OTEC can provide constant power that utilities can depend on any time of day. The electricity it produces could also be used to drive chemical reactions that generate fuel such as hydrogen, ammonia or methanol, Penney added. It might especially benefit island communities or military outposts that rely heavily on imported fuel.
