Bill Gates Funds Seawater-Spraying Cloud Machines

lucidkoan writes "Environmentalists have long argued about whether geoengineering (using technology to alter the climate) is a good way to tackle climate change. But the tactic has some heavy hitters on its side, including Bill Gates. The Microsoft founder recently announced plans to invest $300,000 into research for machines that suck up seawater and spray it into the air, seeding white clouds that reflect rays of sunlight away from Earth. The machines, developed by a San Francisco-based research group called Silver Lining, turn seawater into tiny particles that can be shot up over 3,000 feet in the air. The particles increase the density of clouds by increasing the amount of nuclei contained within."

We might as well geoengineer some more to try and fix the problems. The path to using this techs is pretty clear.

      As far as "masking" the problem, what is wrong with that? So we need to run a bunch of sprinklers in the ocean. Is it cheaper than the substantial costs of reducing CO2 output now? If it is, then we should seriously think about doing it. That isn't to say that we shouldn't work on removing CO2 in a more permanent way or work on emitting less, but it could be a hell of a lot cheaper and political far more feasible than the alternative. Do you have to maintain these and replace them? Sure, but that goes with almost any technology. It isn't like the fact that power plants wear out stop us from building an electrical grid. You just include replacement in the cost. It is hardly an insurmountable problem.

      If you really believe that climageddon is upon us, geoengineering really is shaping up to be the only way to level off the warming. The cost to reduce CO2 emissions now at levels high enough to stop global warming are through the roof. The political cost is even higher (if not utterly unpayable). We are going to fail at reducing CO2 emissions in the short term. Why not deploy technology to counteract our unintentional geoengineering at a fraction of the cost of "fixing" the problem. Don't stop working on the problem, just give the world some breathing room. Transitioning over to clean and renewable energy is the direction we want to go regardless, making it so that we need to make the transition in a few generations rather than a few years results in a drastically reduced cost.

      Frankly, I think that geoengineering makes hardcore environmentalist pissy because it snatches away the best issue that environmentalist movement has had in decades. When it comes down to it, reducing CO2 emission with today's technology boils down to reduced consumption and energy usage. You can tie those two things to pretty much anything in the environmentalist cause. Global warming makes an good proxy in any fight over the environmental.

I'd imagine that the effects of water vapor while accounting for a greater percentage currently (due mainly to the vast area covered with water) would be short lived. The vapor condenses and falls to the ground eventually, not so with some of the other greenhouse gasses. When was the last time you saw liquid CO2 or CH4 fall from the sky?

      As far as a mythical energy source, it really isn't all that hard in fact there are several methods for culling energy from the waves as they pass by.

      One of the methods is to use an articulating "snake" structure that bends as it goes over the waves and generates power (see current uses in the North Sea).

      Another is to use the action of the waves to bob the structure up and down, this can cause a pumping action to occur and transport water from below to the surface (you could ostensibly build a low flow turbine that would work off that).

      Third option involves the use of any available currents in the area to cause an oscillating motion through induced vortexes (this phenomenon is a problem for oil rigs and is usually damped, but you can use a generator for the damping and get some power from it).

      We're sure that CO2 produces warming for a couple of reasons:

      1)All laboratory experiments show this.
      2) All paleoclimate records show this. (To be fair, there are a ton of feedbacks in the system, but historical warm periods are very closely correlated with very high levels of CO2.)
      3) All current observations show a very close correlation between CO2 and global temperature. In fact, there is nothing else that comes anywhere close to that correlation.
      4) With reasonable parameters in models, previous CO2 data very closely predicts current temperatures and temperature distributions.

      From a climate science standpoint, there is absolutely no doubt that increased CO2 leads to increased temperatures. Hell, even from a physics standpoint there's no question about it. In fact, the basic physics and chemistry aren't overly hard. Where the questions lie is in how the earth system as a whole responds to increased temperatures.

      Clouds are perhaps the #1 area of uncertainty at the moment. Venus is scorching hot because of cloud cover and a strong greenhouse effect. Hotter on average than Mercury, which is a lot closer to the sun. Yet Mars is a frozen wasteland with no appreciable greenhouse effect or clouds. From ground and satellite observations we can see that, on average, low, thick clouds reflect more sun than they trap heat, and cause a net cooling. High, thin clouds trap more heat than they reflect, causing net warming.

      But we lack data on "paleoclouds" - nobody really knows if a warmer planet leads to more low clouds or more high clouds. Most of the physics seems to indicate more clouds, (ala Venus) and paleoclimate records show wet periods corresponded with warm periods, and dry periods with cool periods.

      I take a fair bit of issue with your last statement. You don't seem to know much about computational climate models. The entire point is to parametrize physical processes that are too computationally demanding to actually model. We can't model every raindrop, so we model net amounts based on parametrizations which agree with what we see. For instance, many model parametrizations are based on NCEP reanalysis data. It's freely available data, collected from a vast array of measurement devices. Pressure, temperature, humidity, winds, evaporation, precipitation, incoming solar, albedo, etc. The parametrizations we make are an aggreate of real data and pretty well known physical properties.

      The big issues are the things we have no data for. "Paleoclouds", eg. Nobody knows what clouds were like 1 million years ago. We can estimate, based on what we know, but it's just a guess. Even something as simple as albedo is tricky. When we lose permafrost, the albedo of the poles changes. But what does it change to? Obviously it lowers, but the actual value depends on the types and distribution of plants that grow there. We've just got to guess at that. Do these uncertainties mean that global warming isn't happening? Not at all. It just means that the spread of predictions is that much larger.

      One key thing we do know: The deep ocean has about a 1000 year circulation. We can trace the age of the ocean by testing for things like man-made nuclear particles and CFCs, among other things. When we examine 50 year old and newer water vs hundreds of years old water, the CO2 content of the new water is enormously higher. In fact, it looks like the ocean has taken up almost 50% of the CO2 we produced so far. As any chemist, physicist, or anyone who's opened a warm soda can tell you, warm liquids hold less gas. This potential slowdown of our major carbon sink, combined with our increasing emissions will likely have profound effects on future climate, above and beyond what's currently being modeled.

      P.S. The IPCC models are a decade old. They only are using very well established, well reviewed models that have stood the test of time. The newer, more complete, less parametrized, and significantly more complicated models show a spread around the IPCC models. However, the bulk are above IPCC predictions for temperature. It doesn't help that we're following the worst-case IPCC emission scenario.

Let's say it takes 25 years (about 9132 days) for the trees to get big enough to harvest. In that case, you need 292,224 sq miles of land. That's about half a percent of the worlds land area.

      Well, to start, clouds form around aerosols. By definition, an aerosol is a particle small enough that the pull of gravity on its tiny mass is offset by air resistance, so it can remain suspended in the air. Such a high air resistance/mass ratio means shooting them any distance is really hard. It's like trying to throw open tissues 3000' into the air, except harder. Now, this is to make *clouds* - what they're trying to do.

      If you want to seed clouds to make it rain (pretty much the opposite of making a cloud, really.) the best thing is tiny ice particles, followed by silver iodide. Silver iodide is usually used, as it's hard to keep ice solid and the right size. This convinces the moisture to form a crystal structure, similar to the substrate you sprinkled into the cloud.

      Interestingly enough, the vast majority of water that falls from the sky starts as ice! Ice can rapidly grow in a saturated environment. Condensation is a much, much slower process, and is generally balanced by evaporation, even in clouds. Thus, liquid water is about the most useless thing to inject into clouds. Your idea of pumping water into the air wouldn't work, unless it was a really fine vapor, AND there were the aerosols for it to form around. AND it didn't just rain back out. And if you could put water in the air in a really massive quantity. The easiest way to do that would be to use a lake or ocean.

      3000' is, atmospherically speaking, really, really low. Atmospheric scientists rarely use distance measurements, as everything is dependent on pressure. They break the atmosphere up into 100mb/100hPa (they're equal units, mb is older and hPa is metric) sections. Ground level is roughly 1000 hPa on average. The jet stream is in the 200-300 hPa range. (Pressure goes down as you go up, so lower pressure is higher vertically.) The bulk of weather happens between 1000 hPa and 500 hPa. 500 hPa corresponds, roughly, to 18,000'! In fact, when real meteorologists (a large percentage of the ones on TV don't have any sort of atmospheric degree - they have communications degrees!) discuss the weather, it's common for them to look at the 200-300 hPa levels to see what the jets are doing, the 500 hPa level to look at upper atmospheric dynamics, then 800-1000 hPa levels to see what the ground effects are.

      If you put water 3,000' into the air, it won't stay there. It will either fall out, or keep going up. If it keeps going up, it most likely freezes, then comes back down. Inserting a large quantity of ANYTHING into the air with the correct buoyancy for any specific level, but with just enough inertia to get there, and not overshoot, is a ridiculously hard problem.

      If you consider the surface of a pool the ground, and the bottom high enough in the atmosphere that water freezes and comes back down, you can get a good analogy to what they're trying to do. It's akin to jumping into a pool with enough air in your lungs that you end up neutrally buoyant, floating half-way down, without ever touching the bottom. And they're trying to do this in a kiddie pool rather than at the deep end in an olympic pool.

    John Latham is working with several collaborators (including Prof. Tom Choularton, University of Manchester, UK; Prof. Stephen Salter, University of Edinburgh, UK; and Prof. Mike Smith, University of Leeds, UK) on a proposed geo-engineering technique for global warming mitigation (Latham, 1990 and 2002 , Bower et al. 2006). A detailed account of this work is presented in the three papers linked, above.

    The basic principle of the scheme is advertently to increase the droplet number concentration N in maritime stratocumulus clouds, thereby increasing their albedo (reflectivity) for incoming sunlight and also their longevity. This would produce a cooling effect, the magnitude of which could be controlled, and calculations and GCM computations both indicate that its magnitude could be sufficient to balance the warming due to increased atmospheric carbon dioxide concentrations resulting from the burning of fossil fuels. It is proposed to increase N by atomizing seawater at the ocean surface (producing copious quantities of droplets of around 1micron in size), and the significant fraction of these which rise into the low-level clouds above would act as cloud condensation nuclei (CCN), thereby creating additional droplets and enhancing N. The seawater droplets would probably be disseminated from a fleet of satellite-controlled unmanned vessels, deriving their required energy from wind or wave-power. Control over the degree of planetary cooling could be achieved via albedo measurements linked to a global climate model.

    Technological questions regarding the production and dissemination of these particles remain to be resolved. Also, detailed examination of the meteorological and climatological ramifications of this proposed geo-engineering scheme would need to be conducted before justification would exist for its operational deployment. Two advantages of the scheme are that: (1) it is relatively benign, the only raw material being seawater; (2) if the disseminators were switched off, the droplets introduced into the atmosphere would fall back into the oceans within a few days.

This would be less than those people we've all met that toss away a penny because it's not worth having in their pocket. The Gates Foundation gives out over $1.5 billion a year but I don't recall seeing anything on ./ about that.

    Then look at what it is he is doing with this pocket lint amount of cash - paying for RESEARCH into something. Did you read the article? He's not paying anyone to shoot salt water into the air, he's not even paying for research into shooting salt water into the air; he's paying for research into "converting salt water into tiny particles" and pumping that into the air. The navies of the world have been evaporating salt water to produce fresh water for decades (used to be my job).

    Bill Gates seems to be thinking that "global warming" represents some threat to humanity, that needs to be solved by some method, in order to protect humanity. This is not the case. If global warming were about the good of humanity, then global warming advocates would be equally concerned about the Yellowstone supervolcano as they are about "global warming".

    The Yellowstone supervolcano is 40 thousand years overdue and has the potential to wipe out 90% of the population of the US. The Science behind the Yellowstone supervolcano is much less speculative that "global warming". It is definely known that this MF will go off.

    I believe that with a concerted effort and spending a lot of money the American people could reduce the death toll to only 50%! The area of total devastation will probably only be 4 states. Most people will probably be killed by cascade effects that could be planned for and prevented at a huge cost. Things like starvation from not having stored enough food for the "volcanic winter" when several years harvests are lost. Things like the power being out for years because of volcanic dust shorting out the power lines. Things like massive riots by starving people because of economic and political collapse because the physical economy was not built strong enough. Many of these things could be planned for and prevented.

    But it is not going to happen. There is no way for a politician to buy votes, or a bureaucrat to collect bribes, by solving a problem that most people do not want to think about.

    But to return to "global warming" and Bill Gates' mistake. "Global warming" is not about the good of humanity. If "global warming" were about the good of humanity then the global warming advocates would be equally concerned about the yellowstone supervolcano and they are not.

    "Global warming" exists as an issue because it provides the pretext for a massive power grab. Imagine the campaign contributions that a politician can collect if the politician is going to control everyone that needs to have a fire, directly or indirectly. Imagine the bribes that can be collected if you are a bureaucrat regulating everyone with a fire! This is why the global warming issue exists, not the good of humanity.

    Bill Gates' solution does not require the massive power grab to solve the global warming problem. Indeed it undermines the perceived need for such a power grab. It would be the same with any cheap purely technological solution that does not require a bureaucrat regulating everyone with a fire. Gates' solution threatens the true goal of the global warming advocacy. It therefore will be automaticly rejected.

    How well you understand the nature? How it will goes on for 5 years, 15 years, 50 years, 500 years if you turn on that machine?

    How well you known the history of our plannet? How well you known the history of weather on this plannet?

    learn to respect please.
