 NOAA bureaucracy a threat to OTEC?Doug Carlsson wonders if NOAA bureaucracy could be a major threat to OTEC implementation? He tells us the grapewine provides the following rumours: "NOAA is so gummed up with bureaucratic inertia due to the “shell shock” it feels over the enormity of ocean thermal energy conversion that it will demand five years of operating data from even a pilot plant before giving OTEC its regulatory blessing. We would love to hear from anyone who can confirm or deny these fears. Thursday, December 10, 2009
French defence manufacturer working on OTEC?Ares, a blog at Aviation Week, is saying that "Expansion is also planned into the renewable marine energy sector. An “incubator” will be set up in the Atlantic port of Brest to manage development of floating wind turbine, wave energy turbine, and ocean thermal energy converter demonstrators or prototypes and DCNS will take part in European programs to develop marine current turbines."

Honolulu SWAC Honolulu Weekly has an article about the $240 million sea water air-conditioning system (SWAC) which is being built for Honolulu. "Groundbreaking is expected next summer and the first 40 buildings are expected to come online in late 2012. " And there are investors from Stockholm involved, which is interesting, as one of the first systems in the world was built in Stockholm (where I live) and this is being expanded.

US NOAA visits Hawaii to talk OTECDoug Carlson tells us about a visit by people from the US National Oceanic and Atmospheric Administration (NOAA) in Hawaii, where they learned more about the OTEC efforts planned for the islands. The visitors will, according to Doug, be responsible for "issuing licenses and permits for OTEC plants and operations". "The NOAA team’s meetings in Hawaii “have brought home how much our learning curve has to be based on what’s happening here in Hawaii,” Kehoe said, adding that he believes Hawaii will be the site for the first OTEC demonstration plant. That first plant therefore will be tailored to the issues that will emerge regarding OTEC here." " Sunday, November 01, 2009
US Navy signs $8 million OTEC deal with Lockheed MartinSlightly old news is that Lockheed Martin has penned a deal with the US Navy in September 2009 to "develop critical OTEC system components and further mature its design for an OTEC pilot plant, an incremental step in developing large-scale utility plants. A key part of maturing the plant design includes developing an interface between the system’s cold water pipe and the platform". The deal is worth just over US$8 million. Labels: lockheed martin, otec, US Navy Coldwater pipe for Indian 1 MW OTEC barge ready According to Silicon India the Indian Department of Ocean Development's (DOD) OTEC project is ready to deploy a one kilometre deep cold water pipeline. The pipeline will be installed on a one megawatt barge mounted OTEC installation. DOD secretary Harsh K. Gupta said the one-kilometre-deep underwater pipeline is complete. The barge is ready "and the DOD technical team is only waiting for a fair weather window" to connect the line to the barge". Edit: A reader points out that this article was published on 22 January 2004. Thanks Paul! Not sure how that ended up in my news queue. Sorry about that. Friday, July 17, 2009
 Bill Gates want to use cold seawater to stop hurricanes@hexayurt told me about a system which would use hot seawater to power a process to bring up cold seawater to the surface, and that way "steal" some of the energy which a hurricane uses. This has been mentioned in several places, but here is a sample article about it. Seems to me that a back of the envelope calculation on the thermodynamics of this can give a quick answer to the question: would it work?
