The technical issue would be with the volume of water required. Since you are effectively mixing heat in ocean columns, you would be warming water at depth in proportion to the surface cooling, and one should explore the consequences of this. As you may imagine, this past season's storms have renewed interest in hurricane modification and quite a few proposals are being fielded. I am working with some other faculty at MIT to initiate a funding program for such proposals as yours; if we succeed I will let you know and there would then be a mechanism for you to get funding to work on this.

Questions I would ask include the cost of construction, cost of maintaining the system, side effects to the local marine environment. Whether it actually would work ought to be tested with some modeling. You could contact Kerry Emanuel at MIT to see what he thinks of the possibility of modeling it to see if it actually works as envisioned. --------------------------------------------------------------------------- ----- From: Pat McNulty [mailto:[email protected]] Sent: Saturday, November 12, 2005 1:19 AM To: 'Michael Oppenheimer' Subject: RE: Bernoulli's equation used to modify hurricanes and tornados's Here is how it will work. Anchor a large tunnel to the sea floor like a buoy but in several locations around the tunnel to hold it fast to the sea bed. Position it to where one open end opposes the current at depth where the cool water is and the other open end at the surface faces away from the current. What happens is a difference in pressure is created at both ends and when a pressure difference is created flow occurs. That is the beauty of Bernoulli's principle. Cool water is bought up from below thus mixing with the warm water at the surface. The tunnel is neutrally buoyant with the top end just under the surface. Remember it can only work where there is a current. No current, no difference in pressure. Also, enough electricity can be generated for millions of people in Florida. With the use of both of these principles combined no pumps are needed since the water will flow up the tunnel naturally. They can also be placed in the Yucatan and Caribbean currents thus cooling the Gulf of Mexico via the loop current thus saving the Gulf States, if placed SW of Key West They will save the whole East coast Of North America. The SSTs can be regulated to 70 to 80 degrees by the addition of a gate on the discharge end of the tunnel that regulates the flow of cool water flowing from them. The idea does not eliminate the hurricanes it modifies them to a much weaker state no more than a catagory one by regulating the SSTs. The transfer of heat to the mid latitudes still occurs. The ocean temperature is regulated between 70 and 75 degrees and therefore as the storm crosses the cooler water it just weakens but it is not eliminated. BTW during the winter the temperature of the gulf is below 70 degrees so this should not harm sea life. tornado's may not even form in the mid west because of the cooler temperatures in the Gulf thus cooling the warm air migrating to the North out of the Gulf Of Mexico. Since the air is cooler not as much lift is created in the atmosphere for tornados to form. Pascal's principle: F1 is the force of the gulf stream exerts on the mouth of the tunnel at depth. http://www.scientia.org/cadonline/P...uids/pascal.ASP Bernoulli's principle: A negative pressure is created when the gulf stream rushs pass the exit of the tunnel near the surface. http://theory.uwinnipeg.ca/mod_tech/node68.html All I did was combine both principles together to make the thing work with the tunnel. Any thoughts?

Let me think about it some more. Generally, I'm skeptical of geo-engineering but maybe you've got something here. --------------------------------------------------------------------------- ----- From: Pat McNulty [mailto:[email protected]] Sent: Thursday, October 27, 2005 7:56 PM To: [email protected] Subject: Bernoulli's equation used to modify hurricanes and tornados's Michael, I have two neat ideas to modify hurricanes that will work physically. Bernoulli's Principle and underwater tunnels can weaken hurricanes just as the principle works on an airplanes wing creating lift. It works for fluids and gasses. They can create upwelling in the path of a storm thus weaken it. They can only work where a current exists such as the Gulf stream current or the Caribbean and Yucatan currents. The current that runs through the tunnels can be turned on or off and can restore proper temperatures to the oceans sea surface temperatures thus regulating them. If placed in the proper locations these tunnels would reduce a hurricane or tornado's impact. It may even prevent a tornado from forming at all. These tunnels by product can produce enough electricity for the world without warming the planet. Wow imagine the effects when a billion more people buy cars and get electricity in just 15 years in China. Any thoughts?? This next email is from Hugh Willoughby. http://www.ihc.fiu.edu/people/bios/willoughby.htm As I wrote earlier, the loop current is hundreds of kilometers across and its position varies greatly from year to year. What makes the scoops not completely nuts as a proposal is the narrowness and fixed position of the Gulf Stream in the Straits and off Florida's SE coast. In terms of climatology, Greater Miami is the most vulnerable major city in the US. Only Miami has the configuration of a deep "western boundary" current directly offshore. Thus this scheme, if it proves feasible, would work only for Miami and only for Andrew-like storms. The city would remain vulnerable to late season storms, which approach from the SW, like WILMA hew From: "Pat McNulty" Date: 2005/10/23 Sun AM 12:15:36 EDT To: Subject: RE: Scoops( Under water Tunnels) Isn't there also a loop current in the central gulf? If so it may prevent one from becoming organized and prevent rapid development thus the impact would be less at landfall. Hopefully, ssts have been cooled by the other storms this year. However, any big city that can be protected should be protected if such technology exists. It is just going to get worse if we just sit on our hands. I predict storms getting much worse than they are now.
