Science may help cool the planet

The Times of Israel reports:

An Israeli tech company has revealed the content of tiny particles it hopes will one day be used to combat global warming by scattering millions of tons of them into the atmosphere to reflect away sunlight, the New York Times reported Thursday.

Stardust Solutions had previously kept the makeup of its geoengineering particles a closely-guarded secret, protected with nondisclosure agreements.

As it turns out, they are made from amorphous silica, which is a food additive, and calcium carbonate, which is in eggshells and limestone. …

So far, the company has only tested the particles in the laboratory and says it would not test them outdoors unless it were in partnership with a government to lay down the rules and limits of the test, according to the report.

Hey this could be an opportunity for New Zealand. Science is amazing.
