God such a tantalizing solar punk dream. I would love just to hear the inside of an electric commercial airliner at altitude.

The fan could then switch over to a https://newatlas.com/automotive/inside-out-wankel/ https://newatlas.com/automotive/inside-out-wankel/ when at cruising altitude. Using biofuels, or carbon air capture, we get long range and a closed carbon cycle.
