Scientists think they can control weather with lasers
The existence of condensation, storms and lightning are all due to the presence of large amounts of static electricity in the clouds. Researchers from the University of Central Florida and the University of Arizona say that a laser beam could activate those large amounts of static electricity and create storms on demand.
By surrounding a beam with another beam that will act as an energy reservoir, the central beam will be sustained for greater distances than previously possible. The secondary beam will refuel and help to prevent the dissipation of the primary beam, which would break down quickly on its own.
"The collapse becomes so intense that electrons in the air's oxygen and nitrogen are ripped off creating plasma -- basically a soup of electrons," Mills explained in a statement.
Afterwards, the plasma tries to spread the beam back out -- causing an internal struggle between collapsing and spreading -- what's known as "filamentation." This process in turn creates a light string that lasts only until the beam disperses.
"Because a filament creates excited electrons in its wake as it moves, it artificially seeds the conditions necessary for rain and lightning to occur," Mills explained
