Boeing's Jets of the Future Will Be 60 Percent More Fuel Efficient Thanks to Natural Gas

Using the moniker SUGAR (Subsonic Ultra Green Aircraft Research), Boeing has been hard at work developing a series of jets that will take us from point A to point B in the future. They've already developed concepts for a hybrid-electric passenger jet, and now with the SUGAR Freeze, they reveal their plans for an aircraft powered by natural gas.

Though we won't even see a SUGAR Freeze craft in action until 2035, Aviation Week says the excitement revolves around Boeing's planned use for liquified natural gas. Intended to be burned in a hybrid engine, the LNG propulsion system would connect to a fuel cell and would theoretically be 64% more efficient that current passenger jets.

Considering that planes are responsible for a significant amount of carbon emissions, such technologies would be huge for the environment. Here's hoping it actually happens. [Aviation Week via Dvice via Engadget]
