So Pina2bo was what T.R. called the complex where he planned to do basically the same thing, on a smaller scale. Pina2bo would have to operate full blast for many years to put as much SO 2 into the stratosphere as its namesake had done in a few minutes. Since the stuff began to fall out of the atmosphere after a few years, the best that Pina2bo could ever achieve was just a fraction of the real Mount Pinatubo eruption. But enough to begin making a difference. And if the first one worked, more of them could be built.
