Boeing’s SUGAR Freeze is a cool way to power a plane

No, not the sensation you get when you have gulped your ice cream too fast. SUGAR Freeze is the a new propulsion concept developed by Boeing that aims to revolutionize air travel. Standing for Subsonic Ultra Green Aircraft Research, the NASA-commissioned project (codenamed “N+4″) looks at immature technologies in the hope of kickstarting research for the future. It’s reportedly 60 percent more efficient than the equivalent Boeing 737-800, thanks to a very experimental propulsion system. Cryogenically stored liquified natural gas (hence “Freeze”) is burned in a pair of unducted fan engines while also powering a solid-oxide fuel cell as an aft-thruster. With LNG projected to remain abundant, more environmentally friendly and cheap well into the century, it makes an ideal substitute to current aviation fuel, which is none of those things. Currently it’s far too unsafe a design to contemplate building, and there are concerns about methane in the natural gas production process, but hopes remain that the kinks will be ironed out well before the 2045 deadline.

I have always been a tech enthusiast, to the point where i have become an addict. Tech to me is crack; Always trying to get my fix every chance i get ! I have always loved sharing anything that fascinates me which again most of the time is about tech related content. I used to share content on Google Reader Shared pages ( but after their not so brilliant idea to shut it down i felt i needed a new platform where i could share and distribute content and thats how came about. So keep reading and get Nlyten ed !
