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?

Guam OTEC numbers misleading
According to people who are familiar with the subject (but wanted to remain anonymous) the $1.5 billion quoted as US Navy OTEC work for Guam is essentially wrong. My sources said that they didn't think it would be more than a tenth of that at most. Furthermore, nobody actually knows today where and if the US Navy actually will build any OTEC facilities. The feasibility studies may (or may not) lead to OTEC development at Hawaii, Diego Garcia or Guam.
