Engineers at Ford are testing a new hydrogen fuel internal combustion engine (H2ICE) that reduces noxious emissions by 99.7% compared to gasoline combustion engines of similar size and power. Ford's P2000 research vehicle emits mostly water vapor and a small amount of carbon dioxide from the exhaust. It would take 300 hydrogen-powered vehicles to emit the same amount of carbon dioxide that comes from a single gasoline engine. "We made big improvements to this hydrogen engine by increasing the compression ratio and reducing oil consumption," says William Stockhausen, a staff technical specialist on Ford's H2ICE project. Other improvements include adding a solid-film lubricant and hard-surface treatments to the fuel injector system and a triple-redundant safety system. "We wanted to err on the side of safety," says Stockhausen. The P2000 H2ICE uses a modified Zetec 2.0-liter engine. Ford test results indicate the new engine is 25 to 30% more efficient than its gasoline counterpart. Ford's web site address is www.ford.com.
The Space Kid, 11, will be one of the first civilians to have his design manufactured in space by NASA, thanks to the City X Project, which inspires kids to think about new 3D-printed inventions that could be useful for humans living in space.
