Metals Manufactured In Space Could Increase Jet Engine Efficiency

The European Space Agency is looking into manufacturing intermetallic materials in zero gravity space to cut the weight of jet engines in half and increase fuel efficiency. Intermetallic materials are different than alloys in that they are combined at the molecular level, as opposed to merely melting down metals and… » 5/12/08 7:00pm 5/12/08 7:00pm
