I came across this article about Bill Gates new patent on an invention to decrease hurricane intensity. It might be old news to some but I thought it was really interesting. In 2008 Bill Gates filed for several structure patents which are designed to weaken or even dissipate hurricanes directed toward the United States' Gulf coast. As these deadly hurricanes form as a result of warm ocean surface water (among other things), Gates' new project design would churn the cold, deep ocean water in hopes for it to mix with the warm surface water.
"According to NASA, low sea surface temperatures can spell death for a hurricane, as happened in 1998 when the cold water Hurricane Bonnie left in its wake caused Hurricane Danielle, which was following close behind, to dissipate. Thus, there is reason to suspect that a significant amount of cold water could cause a hurricane to dissipate.
There are two ideas behind Gates' patent idea. First, the lower depths of the ocean may be used as a huge heat/energy sink. In this method warm ocean surface water is pushed in a downward direction to exit into the cold ocean depths, operating in a continuous cycle. Second, while the primary conduit pushes water down, in an alternative version a secondary conduit may be used to bring cold water to the surface to aid in cooling the warm surface water regions by mixing of subsurface water with surface water."
While the magnitude of the effort might be considerable, perhaps even to the point that it may never become feasible, the physics involved are plausible, and looking at the heat graph above showing how Danielle never materialized it does not seem as if there is a large temperature difference required. Perhaps it is unrealistic to think that anything man made could dissipate a hurricane, but perhaps lessening hurricanes is far more possible. Given the harm caused by hurricanes, there will no doubt be some who continue to follow this and other paths in an effort to control their deadly and damaging affects. your thoughts?
