Green chimney could save the planet

A new power plant chimney that converts greenhouse gases into helpful substances could have a huge impact on global warming.

Fremont, Ohio (FSB Magazine) -- "This is my sandbox, where I play," says Tom Kiser, pulling his big Chrysler sedan into the parking lot of Professional Supply Inc. We're in Fremont, Ohio, population 17,000. There's a sauerkraut factory across the street, a fitting neighbor to Kiser's dreary, plywood-paneled headquarters.

Kiser was born and raised in Fremont. He founded PSI here in 1979 with an $80,000 SBA loan backed in part by his wife's wedding ring, and he's done well enough that he now owns a seven-passenger company jet. But that's not the story. The story is how a small-town heating and ventilation engineer with no illusions about his customers' true priorities ("What makes me go is, Can I make you money? If I can't, don't hire me") suddenly finds himself on the front lines of the fight to halt global warming.
