Donald Sutherland's Riding-Mower Pipe-Organ Rain-Seed Gun To Be Replaced By Kilometer-High Suspended Hose And Stadium-Sized Hydrogen Balloon

“Next month, researchers in the U.K. will start to pump water nearly a kilometer up into the atmosphere, by way of a suspended hose. The experiment is the first major test of a piping system that could one day spew sulfate particles into the stratosphere at an altitude of 20 kilometers, supported by a stadium-size hydrogen balloon. The goal is geoengineering, or the ‘deliberate, large-scale manipulation of the planetary environment’ in the words of the Royal Society of London, which provides scientific advice to policymakers. In this case, researchers are attempting to re-create the effects of volcanic eruptions to artificially cool Earth.”
