A cloudbuster is a device designed by Austrian psychoanalyst Wilhelm Reich (1897–1957), which Reich claimed could produce rain by manipulating what he called "orgone energy" present in the atmosphere.[1]
The cloudbuster was intended to be used in a way similar to a lightning rod: focusing it on a location in the sky and grounding it in some material that was presumed to absorb orgone—such as a body of water—would draw the orgone energy out of the atmosphere, causing the formation of clouds and rain. Reich conducted dozens of experiments with the cloudbuster, calling the research "Cosmic orgone engineering".[1]
There have been no verified instances of a cloudbuster actually working and producing noticeable weather change, such as causing rain. Orgone therapy is seen as pseudoscience.[2]
A modern reinvention of cloudbuster is being sold under names of chembuster, orgone cannon or akasha pillar. It is marketed as a countermeasure against chemtrails (conspiracy theory relating to aircraft condensation trails).[3][4]
