Re: Greenwash?
It might have some use as a research project but it is pure greenwash. Too many people have been sucked in to the UN green agenda and think that being green is the way to go.
All this does is add extra weight to the airframe for no useful purpose as you say. Large banks of lithium batteries are heavy and are a fire hazard that needs special treatment for safety, all of which adds weight which is not wanted in an aircraft because it reduces the amount of revenue generation for a given volume.
The only thing going for this is that it appears to be 'a good thing' for these companies shareholders.
