Nitrogen oxides have also been shown to be associated with respiratory diseases and cardiovascular disorders, resulting in about 16,000 deaths a year, [according to an MIT blurb](). A 95 percent reduction in these emissions could cut those deaths by 92 percent, saving tens of thousands of lives annually. "This would still be a tremendous engineering challenge, but there aren’t fundamental physics limitations," said Steven Barrett, professor of aeronautics and astronautics at MIT, in the statement. "If you want to get to a net-zero aviation sector, this is a potential way of solving the air pollution part of it, which is significant, and in a way that’s technologically quite viable." ## Almost Electric While the new hybrid-electric plane's main source of thrust is still a conventional gas turbine — in this case located in the cargo hold, not on the wings themselves — such a turbine would drive a generator to produce electricity instead. This energy would then power wing-mounted electric propellers. The turbine's emissions would also be further cut through the use of an emissions-control system, like the ones found on modern heavy-duty diesel trucks. ![]() ## No Limits According to Barrett, the concept is one possible answer to the fact that battery technology [simply isn't there yet]() for larger aircraft. Electrifying them "won’t happen anytime soon without pretty major breakthroughs in battery technology," Barrett said. While the extra heft of the hybrid-electric system would require 0.6 percent more fuel to fly a converted Boeing 737 or Airbus A320, emissions would be cut significantly thanks to the emissions control system. **READ MORE:** [Concept for a hybrid-electric plane may reduce aviation’s air pollution problem]() \[MIT News\] **More on electric planes:** *[Watch the World's Largest Electric Plane Take to the Skies]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
