The phone-booth-size machine humming away in a
Tucson lab may look like a science-fair project on steroids. Its
inventors, however, say it's a potent new weapon in the battle against
global warming.
Its task is elegantly direct. The 9-foot-tall
device, encased in see-through plastic, scrapes the chief global
warming gas — carbon dioxide — right out of the atmosphere. As air
wafts through, CO2 sticks to large chemically coated panels
while oxygen and other innocuous gases breeze by. The carbon inhaler's
developer, Global Research Technologies, is among hundreds of U.S.
companies scouring for ways to reduce the world's greenhouse gas
emissions and cash in on federal requirements anticipated by 2010 to
combat global warming.
"It's a gold rush," says Peter Fusaro, head of consulting firm Global Change Associates.
The CO2-busting industry is exploding
as federal legislation to cap the emissions of utilities and other
industries grows more likely, offering the prospect of huge profits.
Nearly 400 start-ups are operating 600 carbon-mitigation projects in
the USA, with the number of companies set to triple the next two years,
says consulting firm Point Carbon.
