Default Future of aviation, or flash in the pan??

I do hope they find safer battery chemistries before long. LiFePO4 is much safer, but the energy density is even poorer and the cost even higher.



Reading more on the Alice project, they intend to do an Extended Range
version with about 750 mile range, pressurized cabin, and dramatically
upgraded batteries.

Aluminum-air batteries, with much more energy density than
lithium-cobalt. Aluminum anodes are reduced to hydrated aluminum.
Unfortunately they're primary batteries, not rechargeable. To reuse,
you just extract the anodes, and refine them back to aluminum. Easy in
theory, but may slow down a commercial operation. Or you keep spare
batteries on hand, and swap them out. Probably not with a fork truck,
didn't see any cargo doors on the Alice.

This will be certified and in commercial operation by 2023, buy your
tickets now.
