Thank you for the proposal. 1) Have there been any studies / calculations to indicate the effects on marine stratocumulus clouds of what is being proposed? 2) What might be potential scale of carbon dioxide removal effects (involving gas dissolved in cloud droplets)?

1) Bill Gates unselfishly donated almost 5 million dollars on climate research, in a bold attempt, to find the best technological options available to safely cool down our planet. When the smoke all cleared, the scientists concluded that our planet can possibly tolerate twice the present carbon dioxide levels with no upward temperature change, if we could just increase the amount of solar energy reflected back out into space by about 2.0%. (Please see: The Radiative Forcing Potential of Different Climate Geoengineering Options by T.M. Lenton and N.E. Vaughan.) Also - informational contributions by John Latham, Stephen Salter, and Phil Raush in their R & D pursuit of advanced technology. 2) Please see the research of atmospheric scientist, Jeffery Collett Jr., from Colorado State University titled, " Atmospheric Chemists Show Morning Fog Captures Particulate Matter". Hydrated lime with a PH of 12 when cooled will spontaneously react with (CO2) and methane (CH4) until the lime is converted back to calcium carbonate which is crucial to balance coral reef development and survival.

I'm not convinced the process as described will work in any practical capacity. The water will exist as steam when heated. I'm not clear how any limewater can therefore be carried into the cloud droplets. Surely this limewater component will remain as a solid, or will rapidly form an aerosol. Cloud droplets generally have a short lifetime. This idea would require the creation of large volumes of cloud particles. It appears that there is no leverage in this process - no mention of cloud condensation nuclei is made. It instead seems you aim to create clouds directly. This appears superficially to be energetically impossible on a meaningful scale.

Andrew, If you will reread Cloudtec (SRM) (CDR), please note that I referenced information quoted from 2 of the top scientists in the world, Ken Caldeira and Greg H. Rau. Since you are the moderator for the Google Geoengineering Blog, I urge you to publish Cloudtec (SRM) (CDR) and ask your readers to enter the Climate CoLab Contest with their best (SRM) (CDR) hybrid strategy that uses free energy to help cool and remove atmospheric pollution from our planet in one application!

I'm wondering if you could perhaps explain in a comment the distinctions between your two proposals. Both appear to be related to using the energy from volcanic rock to make clouds. I commented on a couple of aspects of the idea in a comment under the "Exploiting Volcanoes" proposal, and would add those notes here, but the proposals in general seem so similar that I am not sure that is worthwhile. So, it would help greatly if you could summarize how the two proposals are both similar and different, it would greatly help in their consideration.

Exploiting Volcanoes 101 is focused on using a FREE natural energy source to vaporize and expand volumes of seawater 4,000 times into thousands of cubic miles of white, maritime, stratocumulus clouds to enhance Solar Radiation Management(SRM). Cloudtec (SRM) (CDR) utilizes this same natural phenomenon to vaporize and expand a prescriptive blend of seawater / limewater to the atmosphere, where it cools and spontaneously reacts with CO2 until converted back to calcium bicarbonate which is crucial to help balance coral reef development and survival. According to the following quote from Nature Geoscience; Published online 21 April 2013 . . "This implies that geo-engineering schemes aimed at reducing global warming without removing carbon dioxide from the atmosphere would fail to fully mitigate precipitation changes in the tropics. Strategies that may help constrain rainfall projections are suggested." Please see attached;http://www.nature.com/ngeo/journal/vaop/ncurrent/full/ngeo1799.html _______________________________________________________________________________________________ I, seriously, believe Cloudtec (SRM) (CDR) may fulfill these requirements!

Thank you for sharing your ideas and for the work invested to create this proposal. We have considered this proposal carefully, and note that the approach for generating clouds in the scheme presented here is similar to your proposal titled "Exploiting Volcanoes" (although the reactants differ in the two proposals). However, the issues that have been raised in previous comments made by the contest Advisor on that proposal (Exploiting Volcanoes) have not been addressed sufficiently to convince the judges that clouds can be generated as described here and therefore that this scheme is feasible.
