Secretive aerospace company Otto has unveiled the Celera 500L. The super efficient aircraft seats six and has up to ten times the fuel efficiency of a private jet while offering similar speeds. With a range of up to 4,500 miles, it could theoretically fly between any two airports in the continental U.S. without refueling.
CO2 emissions from air travel pose a serious challenge to efforts to control climate change. This new aircraft uses an extremely efficient shape designed to optimize laminar flow and a V12 piston engine to dramatically improve fuel efficiency relative to conventional jet aircraft.
