“I would argue that, you know, Having no option is not a good balance for this. You need to have options. You want to make sure that you are not stuck in a position that in 10 years from now, people are saying, why no one worked on, on giving us option?”

Yedvab: Stardust silica particles can offset 50 years of global warming
“We believe that for, I would say, to provide cooling, which is comparable to the heating of the last 50 years, our simpler particle, the one which is composed of amorphous silica by itself is enough, but if you need to go higher, the second more complex partic…”

Yedvab: 0.5 degrees of cooling costs $10 billion using Stardust particles
“So in, in terms of giving orders of magnitude or estimates, and we have a very detailed breakdown for every million tons of particles that will be Dispersed, the cost will be roughly ten billion dollars, and you'll get half a degree of cooling.”
