This reminds me of 10 years ago when it came to EV's.
They will never work.
Nobody will ever buy them
Impractical
Just a fad
Here we are in 2019 and there are Teslas everywhere and the rest of the market is throttling up on EV's. Plus, the resources that are going onto batteries is massive. When we finally get solid state batteries, that's going to be another game changer. So, being all down on E-Vtol's is just a reaction of old people that believe it has to have gasoline for it to work for them. Good part is, there is a younger generation that has a different idea. Unless Moller goes electric, it'll never see the light of day. That's where the investments are going, not in an ICE VTOL.
