Silver Lining will develop machines to convert seawater into microscopic particles capable of being blown up to the cloud level of 1,000 meters. This would whiten clouds by increasing the number of nuclei. The trial would involve ten ships and 10,000sq km (3,800sq miles) of ocean. Armand Neukermanns, who is leading the research, said that whitening clouds was “the most benign form of engineering” because, while it might alter rainfall, the effects would cease soon after the machines were switched off.

Well, I like the fact that he's trying new and different things and thinking outside the box, even if he's mostly just going after crapshoots. It's his money, though, so he can have at it.

The OP, JRDunassigned, has given us a quote from Times Online and also there is a link to the Times Online article. Brief comment, on May 12, 2010, Gretchen Weber wrote an article, Geoengineering Field Tests on the Horizon? Here it is.

Bill Gates may investing in geoengineering projects, but a widely-quoted news story reporting that he contributed $300,000 to a San Francisco company to launch climate-intervention field tests is full of inaccuracies, according to one scientist involved. The article, which appeared Monday on the Times Online website, asserts that Gates gave the company, Silver Lining Project, the funds to develop machines to spray seawater up to 1,000 meters into the sky in efforts to whiten clouds and increase their reflectivity, thus blocking the sun and ultimately slowing the rate of atmospheric warming. The article then describes a planned field trial, which would involve 10 ships and 10,000 square km of ocean, leading some readers to assume that Gates is funding the largest-scale geoengineering field test to date.

According to Ken Caldeira of the Carnegie Institute of Global Ecology at Stanford, Silver Lining has received no funds from Gates personally. Instead, he said, the $300,000 was allotted by Caldeira and David Keith, who have been directing geoengineering project funding for Gates. Caldeira explained in an email that the scientists dispensed funds not to Silver Lining for field tests, but to engineer Armand Neukermans and his team, "to test the feasibility of fine seawater sprays in the laboratory."

"There was no funding given for the planning, preparation, or execution of any field tests," Caldeira wrote. "I have expressly said that private efforts to conduct field tests should await the development of appropriate governance structures. I am opposed to private entities conducting field tests without appropriate governance and would oppose funding such activities."

Honestly, I've never been impressed by Times Online's articles.

I'm curious as to how they plan to measure the effectiveness of the effort. High altitude or satellite photography? How much albedo change do they think they can produce? One in a thousand? Million?

I don't have any answers to your questions, mheslep. It seems as though engineer Armand Neukerman's Silver Lining Project is at this time 'to test the feasibility of fine seawater sprays in the laboratory'.

I would also encourage viewers to open my last link and preview other links in the article.

Have a nice weekend to one and all. I have a barbeque fest at my house today!

It doesn't really sound new to me. It is called cloud seeding and it has been studied or used for almost a century now.

Eh? This project differs in means and desired outcome. There's no silver iodide or other compound other than sea water being sent aloft here, and the desired outcome is not increased precipitation but more cloud cover, which must be done with some efficiency since eventual scale is global.

these clouds can't produce rain, right? If it did, it would have some practical applications when it comes to taking out mountain fires, etc
