Is It a Bird? Is It a Plane?

Faradair is a UK startup. It is one of the companies vieing to develop a short-hop, hydrid aircraft (https://www.theguardian.com/environment/2021/mar/18/will-a-british-bioelectric-hybrid-plane-really-take-off). Faradair's Beha craft is designed to use electricity for take off and landing. These are the most polluting stages of traditional jet travel. These phases are also the noisiest. So, the Beha would reduce both carbon emissions and noise disturbance. It is not currently possible to do the whole flight electrically. The plane would consequently switch to a biofuel-powered turbogenerator, whilst in flight. The Beha would have a modest top speed of 230 mph but could carry passengers or freight. It could also use short runways as it has impressive lift. Its turbogenerator, assisted by solar panels on the wings, would recharge the batteries, whilst in flight. This would mean that electricity charging points would not be needed at airports. There are currently some reservations about biofuels. These are somewhat optimistically termed Sustainable Aviation Fuels (SAFs). They are are made from waste oils, surplus food and foodstock. Currently, SAFs only account for 8% of jet fuel. Although they recycle waste materials (rather than use 'new' oil), they would still put carbon dioxide into the atmosphere.
