Hello, I'm new here and I expect to make a few blunders until I am better acquainted with previous discussions. I am a retired physicist and have some leadership role in the Sierra Club. The Salter Sink is an excellent concept for raising cold water to the surface. the area that needs design attention is the injection system at the bottom of the tube. With careful design, it will raise probably ten times as much cold water as is pumped down. This design work is quite easy. Next, I had never considered the advantage of the wave-driven pump as a way to cool the ocean, rather as a way to raise nutrients to the surface to increase biological production. Most of the ocean surface world-wide is limited in production by inadequate nitrate and phosphate rather than iron. Some good places for hurricane control are also good for placement of "ocean farms" fed by wave pumps. For example, the North Atlantic Gyre region, also known as the Sargasso Sea. I believe if somebody will check the economic potential of pump-fed sea farms in some areas such as the horse latitudes, it will be found that the Salter pumps will pay for themselves and return a handsome profit. My thought-- it isn't necessary to remove the pump structures before they encounter storms--if they are lowered below the surface by about 100 meters, then they are completely sheltered from the storm above. I can imagine a Salter pump connected to a lattice structure that spreads over an area of sea around the pump. Kelp or other suitable plants are anchored to the lattice. The "farm" provides a sea pasture in which farm animals are grown and harvested for market. Ernie Rogers Pleasant Grove, Utah Phone 801-368-4902

My main objection was that Fareed or his show producers seemed to not be aware of the limitations of SRM. By this I mean that the fundamental causation agent - excess CO2 - was ignored, not mentioned once. Greg Lau's message to the list just earlier on the need to protect against ocean acidification was never hinted at. (More tomorrow on that.) The end of the twenty minutes was on Myrhvold's firms focus on investing in inventions - which he says only his new firm is doing (emphasizing this is not the same as venture capital - which he also claimed has revolutionized modern American (world?) business). I wish I knew whether Myrhvold himself was working on CO2 removal as well as his SO2 approach. The site also has quite a bit on the Salton Sink concept (see http://www.intvenlab.com/wp-content/uploads/2009/10/Salter-Sink-white-paper- 300dpi1.pdf). Also see http://intellectualventureslab.com/?p=338 for added material on geoengineering. Ron John Nissen wrote: > Hi all > > Have you seen this?
