Funding the All-electric Aircraft

Posted in Physics at 2:00 pm by David Bradley -- 2 Comments; add yours

Today, Philippe Masson of the FAMU-FSU College of Engineering and Center for Advanced Power Systems and colleagues at NASA and Georgia Tech publish details of an entirely new class of aircraft engine that, if it takes off, could lead to an all-electric aircraft that would cut airport pollution and reduce aircraft vapor trails to a distant memory. You can read my write-up about the work on the AlphaGalileo site …
