New look at old idea could be a rainmaker <br />I <br />: By Launce Rake <lrake@lasvegassun.com> <br />: Las Vegas Sun <br /> <br />The elusive dream of making rain may still be impossible, but decades of <br />research is proving that a once-maligned technology really can pump up how <br />! much precipitation comes from the clouds. <br />I <br />I <br />: Researchers believe that "seeding" clouds with chemicals may be a way to <br />I increase precipitation and augment depleted Colorado River reservoirs, the <br />I main source of Las Vegas' drinking water. <br /> <br />! The Southern Nevada Water Authority in May authorized spending $750,000 <br />: on two consultants, CHM2HiII and Black & Veatch, to investigate different ways <br />to augment the drought-struck river. The options would include such relatively <br />humdrum methods such as removing salt-cedar, a pernicious weed taking over <br />I the banks of wetlands throughout the river's basin. <br /> <br />Cloud seeding is also getting a fresh look. <br /> <br />"We can't dismiss out of hand some of these new technologies," said Ken <br />Albright, Water Authority resource director. "We think it's a viable option for <br />further research." <br /> <br />I <br />. The study should be done next summer. <br /> <br />I Cloud seeding actually has been around for at least 60 years. Essentially, the <br />idea is to add tiny particles - usually silver iodide - into clouds. Ice forms <br />I around the particles, and the growing seeds of ice eventually fall to Earth as <br />I snow or rain. The particles can be added to clouds from aircraft, by ground- <br />I fired rockets or from remote-controlled sites high on mountains. <br /> <br />The effectiveness of cloud seeding, however, is debated. The federal Bureau <br />of Reclamation, which controls the giant reservoirs at lakes Powell and Mead <br />and the lower half of the Colorado River, says that cloud seeding would have <br />only limited effect on the huge river system. <br /> <br />http://www.lasvegassun.comlsunbin/stories/sun/2006/jull06/5666505 3 5 .html <br /> <br />Page 1 of3 <br /> <br /> <br />~rA <br />~ <br />~ <br /> <br /> <br />9/11/2006 <br />
