General Motors Corp., which had been focusing on hydrogen power for alternative fuel vehicles, now plans to sell 1 million cars, pickups and sport utility vehicles powered by gas/electric hybrid engines by mid-decade, according to USA Today. GM had fought making heavy investments in hybrid technology, saying it would have cars and trucks powered by hydrogen fuel cells in driveways after 2010. But technological stumbling blocks and competitive pressures have forced GM to rethink its plans, USA Today said. The fuel cells combine hydrogen and oxygen to produce energy without the pollution of gasoline. Hybrids combine an internal combustion engine and an electric motor to deliver high fuel economy and ultralow emissions.
