Show 'obe! Prize Winner Says Rain May Be Controlled Through Cloud Seeding The Nobel prize-winner. Dr. Irving Langmuir, reported recently re-cently that industrial research on weather has so progressed that under right conditions, with $1 worth of silver iodide, scientists scien-tists have a 30 per cent chance of causing a good rain over 40,-000 40,-000 square miles. Addressing aeronautical engineers en-gineers in New York City, which is- spending millions for new water, Dr. Langmuir said he and his associates at a cost of about $20, had brought down 160 billion gallons of rain in New Mexico October 14, 1948, and 320 billion gallons July 21, 1949. Such downpours would fill new York City's reservoirs to overflowing. Rainfall, the scientist said, may be started by "seeding" a cloud with solid carbon dioxide, liquid carbon dioxide, or silver iodide, which cause raindrops to form by chain reaction and build up into a rainstorm. With industry worried about water shortages, and the federal government considering projects to produce fresh water from sea water, the value of such industrial indus-trial research is evident. The New York Times said editorially that Dr. Langmuir "no rain- making crank, but a Nobel prize winner," should be consulted about New York City's water problems. |
