Truly this is the age of Greenfinger: Billionaire Bill Gates has patented the idea to halt hurricanes by decreasing the surface temperature of the ocean.
The patent calls for a large fleet of specially equipped ships which would
mix warm water from the ocean surface with colder water down below, according to
five new patents that include Microsoft's chairman as a co-inventor. That could
then reduce or perhaps eliminate the heat-driven condensation which hurricanes
feed upon, thus significantly reducing their intensity.
The hurricane-stopper plan apparently hatched from a meeting of Intellectual Ventures, a patent house which regularly gathers scientists and technologists to brainstorm together. TechFlash notes that the official filings came through an Intellectual Ventures affiliate, Searete LLC.
One of the five patents also suggests how
to pay
for the massive seagoing fleet, including selling insurance
policies in hurricane-prone areas -- so much for the billionaire backer.
This represents just the latest in a long line of geoengineering proposals aimed at taming Mother Nature, whether aimed at climate change or hurricanes. Even the prestigious National Academy of Sciences held a workshop in June on geoengineering, although that ended with disagreements on whether the cure might be worse than the problem.
We previously looked at other plans regarding hurricanes, such as sending supersonic jets slicing into the eye of the giant storms. But for now, it's likely that coastal cities should at least invest in more grounded ideas to become hurricane-proof.

Tropical cyclones can be thought of as engines that require warm, moist air as fuel (Emanuel 1987). This warm, moist air cools as it rises in convective clouds (thunderstorms) in the rainbands and eyewall of the hurricane The water vapor in the cloud condenses into water droplets releasing the latent heat which originally evaporated the water. This latent heat provides the energy to drive the tropical cyclone circulation, though actually very little of the heat released is utilized by the storm to lower its surface pressure and increase the wind speeds.
In 1948 Erik Palmen observed that tropical cyclones required ocean temperatures of at least 80°F (26.5°C) for their formation and growth. Later work (e.g., Gray 1979) also pointed out the need for this warm water to be present through a relatively deep layer (~150 ft, 50 m) of the ocean. This 80°F value is tied to the instability of the atmosphere in the tropical and subtropical latitudes. Above this temperature deep convection can occur, but below this value the atmosphere is too stable and little to no thunderstorm activity can be found ( Graham and Barnett 1987).

You may have already seen this patent, from Vladimir Zhekov located in hurricane endangered Key West, FL (a former home of mine as well). It also involves pumping colder water upwards to cool the SST. Instead of wave action, wind turbines are used to generate the pumping power and the platforms are anchored, not free floating as in your design. He also notes that water will need to be pumped from as deep as 500 ft, where he claims the water temperature is generally 11 degrees C, noting that 1L of water at this temperature will cool 15L of water at 26.5 degrees C by 1 degree C. And, like in your plan, the ITCZ (Intertropical Convergence Zone) will be one of the locations where the platforms will be located. Perhaps he can work out a deal with Boone Pickens who is seeking to unload nearly 700 wind turbines he recently purchased.
Abstract:
14. A method to inhibit the formation of hurricanes, comprising: generating
power via a wind-driven power source disposed on a buoyant platform; powering a
water-moving system with the power; transporting water from deeper in an ocean
toward a surface of the ocean via the water-moving system; dispensing the water
from deeper in the ocean near the surface of the ocean; spreading the water from
deeper in the ocean in a manner to cause the mixing of cooler water of the ocean
surface with the water from deeper in the ocean; sensing a temperature of the
water near the surface of the ocean; deactivating the water-moving system if the
sensed temperature of the water near the surface of the ocean is cooler than
approximately 25.5 degrees Celsius; and reactivating the water-moving system if
the sensed temperature of the water nears the surface of the ocean is warmer
than approximately 25.5 degrees Celsius.
15. The method to inhibit the formation of hurricanes as recited in claim 14,
wherein the wind-driven power source is a wind turbine.
16. The method to inhibit the formation of hurricanes as recited in
claim 15, wherein the water-moving system utilizes a generally vertical
discharge water pipe to transport the water from deeper in the ocean to the
ocean surface.
17. The method to inhibit the
formation of hurricanes as recited in claim 16, further comprising: transporting
compressed air from an air compressor powered by the wind-driven power source to
a lower area of the generally vertical discharge water pipe; and mixing the
compressed air from the air compressor with the water in the generally vertical
discharge water pipe, whereby the water in the generally vertical discharge
water pipe is encouraged to rise toward the surface of the ocean.
While the present invention can be utilized anywhere in the world, it is anticipated that the preferable initial use will be in the Atlantic Ocean slightly above the equator, in the general area north of the coasts of the countries of Guyana, Suriname, French Guiana, and Brazil (in the general area of 10° to 16° North and 44° West), in the north trade wind stream area, as shown in FIG. 3. It is in this area that the most dangerous hurricanes that strike the United States are formed. An array of individual modules of the hurricane prevention system 10 can be installed in a single northwardly extending group, illustrated as Array Area A in FIG. 3. Alternatively, multiple arrays of individual modules of the hurricane prevention system 10 can be installed in several groups placed some distance apart, as demonstrated by Array Area A, Array Area B, and Array Area C, in FIG. 4.
A variety of patterns and spacing can be used for the specific placement of the individual modules 10 A, 10 B, 10 C, 10 D, etc., of the hurricane prevention system 10 within the hurricane prevention system array. For example, FIG. 5 illustrates an offset pattern allowing an approximate distance of 1500 feet between the individual modules of the hurricane prevention system 10 . A single offset row may be used, or, as illustrated, multiple offset rows may be used in the same array area. The specific configuration used will depend upon a variety of location specific factors including, for example, the ocean depth and the usual storm track pattern. The pattern of individual modules within the hurricane prevention system array, as well as the placement of the hurricane prevention system arrays, can be modified as required to meet the goal of reducing the sea surface temperature to below 26.5° C. It should be noted that 1 liter of water with a temperature of 10 degrees Celsius can generally cool 15 liters of water from a temperature of 26 degrees Celsius down to 25 degrees Celsius.
A possible auxiliary positive contribution of the hurricane prevention system 10 of the present invention, is that bringing the cooler water from deeper in the ocean to the surface additionally may bring water, nutrients, and/or other beneficial components to the surface, allowing for potential improvement of the environment for living organisms in the area of application. While water mass properties are highly asymmetric and site specific, potential may be realized to ameliorate depletion of oxygen in some areas of the ocean."
There is no shortage of such ideas "floating" around the patent offices. In the references to the above patent, I found http://www.freepatentsonline.com/y2002/0009338.html
which seeks to stop not only hurricanes, but also El Nino by using a pumped gas to move colder water vertically. And this one as well, which uses pumps powered by wind turbines to do nearly the same: http://www.freepatentsonline.com/y2007/0084767.html, http://www.freepatentsonline.com/y2007/0084768.html
and finally, http://www.freepatentsonline.com/y2007/0270057.html
in which wave energy is used with either flexible or fixed wall tubes to pump water to the surface. The patent also discusses spraying the water into the air to release heat energy. This system, badly described as it is, seems most similar to the one you are proposing, although with far less thought about the actual dynamics involved.
In the case of your design, I'm still having a problem accepting that ocean currents won't destroy the flexible tubes, irrespective of surface wave actions.
Won't the cooling effect reach a limiting value after some time? You estimate a 2 degree C cooling down to 60 ft after 1 year, but won't surface heating eventually bring this to a halt? Also, note that in some of the hurricane formation zones, while the temperature down to 150 ft can be around 80F, it can be much higher near the surface, so a 5 degree F (sorry to keep mixing up the units) cooling of 85F water to 60 feet does not preclude hurricane development. I guess I am skeptical about the efficiency of the system in addition to its ruggedness.
One final issue is that of the impact on shipping. If only a few thousand devices are required worldwide, then with proper identification, flashing lights, electronic signals, they can be detected before ships run over them. In the Gulf of Mexico, this may be more difficult to achieve. I also don't see the point of removing them once installed, unless there is a maintenance issue.

Bill Gates, founder of Microsoft, is a man with a permanent light bulb over his head. His latest idea? Controlling the weather. Sounds insane, but in a patent application recently released to the public, Gates and several co-inventors have concocted a scheme to kill hurricanes over the ocean before they wreak havoc on land.
The idea is for barges to pump cold water from the depths of the ocean to create a sort of road block for the hurricane. Since hurricanes cull power from the water's warm temperatures, cooling the water could theoretically lessen the impact or outright dismantle a hurricane.
Intellectual Ventures Lab, an organization built by former Microsoft executives to brainstorm new technologies to benefit mankind, says that this isn't a Plan A or Plan B scenario, but rather a Plan C. Pablos Holman wrote in the company's blog that Big Hurricane Suck would be used when "humans decide that we have exhausted all of our behavior changing and alternative energy options and need to rely on mitigation technologies."
It's hard not to make a joke here about Windows -- the analogy is too powerful. Once Microsoft exhausted its resources patching and promoting Vista, it was forced into pushing Windows 7 out earlier than expected. Stop the storm before it intensifies, lands, and destroys PCs due to faulty builds. Ahh. There, I said it.

A Machine to Stop Hurricanes
It might be possible to suppress hurricanes so they aren’t so devastating to people who live in their path. We’ve been inventing in this area along with climate change and alternative energy sources. Today a patent application related to this was published by the USPTO and TechFlash has written a nice piece about this. Some of the questions that came up in the comments there are about whether this type of inventing should be done in the first place. We absolutely believe that we should investigate our options should the environmental change cause severe disruption. This type of technology is not something humankind would try as a “Plan A” or “Plan B.” These inventions are a “Plan C” where humans decide that we have exhausted all of our behavior changing and alternative energy options and need to rely on mitigation technologies. If our planet is in this severe situation, then our belief is that we should not be starting from scratch at investigating mitigation options.
We’re looking forward to discussing these ideas and will post more about them here later this year.
Pablos, thanks for providing some extra explanation. I’ve posted a follow-up on TechFlash (http://bit.ly/zx5ZK) so that more people will have this additional context.
Also in that post are more comments from the University of Miami’s David Nolan, questioning whether the concept would work as outlined in the patent filings. Would be great to hear your thoughts on those questions, as well.
Environment | Bill Gates | Nathan Myhrvold | Microsoft

The environmental impact was one concern raised by readers following our post detailing the hurricane-supression system proposed by Bill Gates, former Microsoft chief techology officer Nathan Myhrvold and others. In response, one of the people working on the project in Myhrvold's Intellectual Ventures Lab has posted an explanation on the company's site.
"This type of technology is not something humankind would try as a 'Plan A' or 'Plan B,' " writes Paul "Pablos" Holman in the Intellectual Ventures post. "These inventions are a 'Plan C' where humans decide that we have exhausted all of our behavior changing and alternative energy options and need to rely on mitigation technologies. If our planet is in this severe situation, then our belief is that we should not be starting from scratch at investigating mitigation options."
Pablos also posted that as a comment on our original post.
David Nolan, the University of Miami professor we spoke with for the initial post, has since expressed additional doubt about whether the concept would work at all. The plan, as outlined in patent filings by Gates, Myhrvold and others, appears to rely largely on a technique for pushing warm water down to alter the surface temperature of the ocean, rather than bringing cold water up.
Here's what Nolan says:
If that's the case, it's even less likely to work. Some of the warm water would be replaced by cold water coming up from below, but some of it would be replaced by warm water converging from outside the region. Also, it's very hard for cold water to come up from below, as it is cooler and therefore more dense than the warm water above. (When warm fluid lies over cold fluid, as in 99.99% of the ocean, vertical motions are strongly suppressed. This is called "stratification.") Similarly, it's hard for warm water to go down. The idea of using breaking waves to make a column of water that is slightly higher than sea level is a good one, but because it is warmer, the whole column may not even weigh more than the surrounding water even if it is taller.
Pablos from Intellectual Ventures Lab notes that the company will be providing more information about the project later this year, so apart from the environmental questions, it will be interesting to see how they address the issues Nolan raises.
Recent patent filings have shown Bill Gates and his friends exploring subjects as diverse as electromagnetic engines and beer kegs. Now they're thinking even bigger -- trying to stop hurricanes.
Microsoft's chairman is among the inventors listed on a new batch of patent applications that propose using large fleets of vessels to suppress hurricanes through various methods of mixing warm water from the surface of the ocean with colder water at greater depths. The idea is to decrease the surface temperature, reducing or eliminating the heat-driven condensation that fuels the giant storms.
The filings were made by Searete LLC, an entity tied to Intellectual Ventures, the Bellevue-based patent and invention house run by Nathan Myhrvold, the former Microsoft chief technology officer. Myhrvold and several others are listed along with Gates as inventors.

The diagram at right is from one of five related patent applications made public this morning. So how exactly do they plan to stop hurricanes? Here's an excerpt from the filing that explains the diagram.
Vessel 100 is a tub-like structure having one or more walls 110 and a bottom 115. Vessel 100 may be held buoyant in the water by one or more buoyancy tanks 120 which may be used to maintain the buoyancy of vessel 100 and further may be used to control the height of walls 110 above the water level. Vessel 100 also includes a conduit 125 whose horizontal cross section is substantially smaller than the horizontal cross section of the tub portion 130 of the vessel defined by walls 110. In an exemplary embodiment, conduit 125 extends well below the ocean surface including depths below the ocean's thermocline.

In most circumstances, most of the sunlight impinging on the ocean surface is absorbed in the surface layer. The surface layer therefore heats up. Wind and waves move water in this surface layer which distributes heat within it. The temperature may therefore be reasonably uniform to depths extending a few hundred feet down from the ocean surface. Below this mixed layer, however, the temperature decreases rapidly with depth, for example, as much as 20 degrees Celsius with an additional 150 m (500 ft) of depth. This area of rapid transition is called the thermocline. Below it, the temperature continues to decrease with depth, but far more gradually. In the Earth's oceans, approximately 90% of the mass of water is below the thermocline. This deep ocean consists of layers of substantially equal density, being poorly mixed, and may be as cold as -2 to 3.degree. C.
Therefore, the lower depths of the ocean may be used as a huge heat/energy sink which may be exploited by vessel 100. When vessel 100 is deployed at sea, waves 135 may lap over the top of walls 110 to input warm (relative to deeper waters) surface ocean water into tub 130. Tub 130 will fill to a level 140 which is above the average ocean level depicted as level 145. Because of the difference between levels 140 and 145, a pressure head is created thereby pushing warm surface ocean water in a downward direction 150 down through conduit 125 to exit into the cold ocean depths (relative to near surface waters) through one or more openings 155. In an exemplary embodiment, the depth of opening 155 may be located below the ocean's thermocline, the approximate bottom of which is depicted as line 160. This cycle will be continuous in bringing warm surface ocean water to great depth as ocean waves continue to input water into tub 130. If many of vessel 100 are distributed throughout a region of water, the temperature of the surface of the water may be altered.
"Many" is the important concept there at the end.
Gates, Myhrvold and associates aren't the first to propose reducing the ocean's surface temperature as a means of suppressing hurricanes, said David Nolan, an associate professor of meteorology and physical oceanography at the University of Miami's Rosenstiel School of Marine and Atmospheric Science.
"Every couple of years there's a news story that gets picked up for some hurricane-suppression idea," Nolan said via phone this morning. "They’re all kooky in their own way. Some of them are more plausible than others, but they all face an enormous problem of scale. ... You would have to cover an incredible area with this effect to reduce the temperature of the ocean by a significant amount."
Of course, a big difference in this case is that one of the people making the suggestion is one of the world's richest men. But don't look for Gates to fund the deployment of thousands of these vessels. One of the patent filings proposes paying for the equipment through the sale of insurance policies in hurricane-prone areas, in addition to funding from state, federal and local government agencies.
Patent watcher "theodp," who tipped us off to the filings, says he was reminded of "The Simpsons" as he read through them. "The richest man in the world hatches a plan to alter weather and ecology in return for insurance premiums and fees from governments and individuals," he writes. "It's got kind of a Mr. Burns feel to it, no?"
The hurricane-suppression patent applications date to early 2008, but they were first made public this morning.
These and previous Searete LLC patent filings are believed to result from brainstorming sessions regularly held by Intellectual Ventures, in which Gates has been known to take part. It's not clear how or when Intellectual Ventures might go forward with any of these ideas.
I hope that there will be a peer-reviewed publication soon. I may read that since those are not supposed to be written to obfuscate.
Question: Do the patent claimants consider the CO2 that would be released by this mixing of the oceanic layers? Or perhaps it would impact the ability of that part of the ocean to absorb CO2 from the atmosphere. Seems to me that it cannot be a good thing to speed up mixing of the sequestered deep ocean pool.

The site http://press.wrap.org.uk/article/18502/ quotes amounts up
to £8.21 each for truck tyres. Does anyone have figures for the US?
I agree that we should study the biological effects of the first few
sinks very carefully and try to adjust spacing for the best balance
between oxygen, CO2 and nutrients. I would hope that the effects will
avoid those of the deluge of fertilizer coming down the Mississippi.
I do not think that we will be trying to cool a thick layer of the
ocean. We preferentially remove the warmest water from the surface, say
10 to 20 metres depending on our choice of valve wall depth and take it
down to the thermocline at say 200 metres. Nathan Myhrvold's model
suggests that the mixed water rises to the level where it meets water of
its own density and then spreads sideways like a fairly thin rock
stratum. Oil slicks with a higher viscosity spread out quite fast. We
have some control of this depth below the surface by choosing the mixing
ratio though a shape change of the exit. Ken wants us to get it up to
100 metres below the surface where there is enough daylight to get the
phytoplankton started.
As hurricanes provide lots of useful rain we do not want to stop all of
them, just shift the Whitney-Hobgood figure a chosen amount to the left
instead rather than letting it creep to the right.
