“A team of elder Silicon Valley scientists is building an audacious device that might solve one of humanity’s most profound dilemmas — a “cloud whitener” designed to cool a warming planet.
The men — retired physicists, engineers, chemists and computer experts from some of Silicon Valley’s top tech companies — have been meeting four days a week for seven years in the Sunnyvale lab of the Marine Cloud Brightening Project to design a tool that creates perfectly suspended droplets of water resembling fog.
Through painstaking trial and error, the scientists are designing and building a nozzle that emits particles that are small enough to rise and remain suspended in air — 0.2 to 0.3 micrometers, about one-tenth the size of the period at the end of this sentence. The nozzle’s holes are so narrow that they fit only two strands of human hair.”
