These students are putting propeller engines back onto aeroplanes to combat climate change

Most commercial aircraft currently in use are powered by turbofan engines, with a small minority powered by propeller engines. The difference between the two is straightforward; a propeller engines’ thrust comes from a difference in air pressure between the front and back of its blades, created by the rotational motion, whereas in a turbofan engine fuel is combusted under very high pressure and thrust is created by the exiting gas (as well as the spinning turbofan).
