NYTimes.com: Can Some Very Tiny Particles Cool the Planet? One Tech Company Says Yes.

[H simmens]

Big news today as Stardust released its proprietary information - at least some of their information - regarding the nature of the particles that they are testing. 

According to the New York Times article linked to below the response from people like David Keith seems to be fairly positive so far. If I remember correctly he was extremely skeptical and critical that Stardust would be able to come up with particles that would be as advantageous as the particles that are now being considered for use in SAI. It appears that he may have been premature in reaching that conclusion. 

My own view as I’ve expressed before Is that Stardust is performing an absolutely essential role in shaking up a sector that has been dominated by the very conservative cautious and much too slow culture of universities.

 Ideally it would be a number of national governments that would be aggressively taking the lead with universities and similar institutions playing an essential research role in support of national governments.  

In the absence of any national government being aggressive as necessary, despite all the grumbling from the research and Civic NGO Community Stardust appears to be just the spark and the catalyst to substantially accelerate action.

Any analysis of the particles from our scientists would be really useful to hear.

Dear Action Coalition,

The critical question is one of chemical side effects.  If the particle were to be, say, partly arsenic, that might not sell.   We don't know what the particle is, and so some of us with experience in such things must expect the worst.  If stardust wants to reassure us all as to what the particle isn't, that might help.

Yours in Hope,

Dear Action Coalition,

" Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust, and is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs." -- Wikipedia

The particle is amorphous silicon.  Stardust solutions continues to have their convincing work cut out for them.

Yours in Hope,

Paul Klinkman
