Suppose, too, that the best solution involves a helium balloon, several miles of garden hose and a harmless stream of sulfur dioxide being pumped into the upper atmosphere, all at a cost of a single F-22 fighter jet.
Good news, right? Maybe, but not if you’re Al Gore or one of his little helpers.
The hose-in-the-sky approach to global warming is the brainchild of Intellectual Ventures, a Bellevue, Wash.-based firm founded by former Microsoft Chief Technology Officer Nathan Myhrvold. The basic idea is to engineer effects similar to those of the 1991 mega-eruption of Mt. Pinatubo in the Philippines, which spewed so much sulfuric ash into the stratosphere that it cooled the earth by about one degree Fahrenheit for a couple of years.
