The push for ecology can currently be seen in many industries. Engineers from MIT have worked on a very interesting concept of a hybrid electric plane. The goal is clear – a reduction in nitrogen oxide emissions, which in this case could be as much as 95%. Industry experts say this is a huge challenge, but not an impossible one. The aircraft should have a conventional fuel turbine located in the cargo area, which would, however, drive a generator producing electricity for the propellers located on the wings. If something like this will be feasible, it will be over time, because at the moment there are no batteries for airplanes.
