Boeing has this week unveiled a new aircraft and propulsion system called SUGAR Freeze, which has been developed by Boeing to revolutionise air travel and make their planes 60 percent more fuel efficient.
SUGAR which stands for Subsonic Ultra Green Aircraft Research was a project commissioned by NASA and can be seen pictured at the bottom of this article . The new aircraft concept uses cryogenically stored liquified natural gas, which completes the Freeze part of the concepts name.
However at the moment the design is still deemed to unsafe to build at the current time for mass market, and more development has to be carried out to make the natural gas a safe system.
The development team is hoping that after further development the new SUGAR Freeze system will be ready for passenger jets sometime around 2035. For more information on the new concept jump over to the Aviation Week website.
