The San Francisco Bay may soon host a dramatic new environmental project that backers say could solve three problems at once: clean wastewater, remove carbon from the atmosphere, and produce biodiesel fuel. Yet it's gotten remarkably little attention.

"For the most part, people are just ignoring me," says Jonathan Trent, a researcher at NASA Ames Research Center at Moffett Field, who is one of the driving forces behind the project.

GREEN CITY A new multipronged effort to shut down San Francisco's Mirant Potrero Power Plant is raising hopes that the end could be in sight for the controversial fossil-fuel-fired facility.
