An engine known as a blower that acts as a vacuum to extract gas from the landfill is seen at the Simi Valley Landfill and Recycling Center in Simi Valley, California May 8, 2008. It's not turning lead into gold, but General Electric Co is working on a form of modern alchemy, converting garbage into electricity. GE, which aims to make $25 billion in annual sales from green businesses by 2010, is working to adapt its gasification technology, used to burn coal more cleanly, to turn municipal waste into a relatively clean-burning gas.
