What is the minimum range needed for reserve etc? Can this minimum be achieved by batteries and electric engine (maybe propeller) instead of kerosene and jet engine?
What is the maximum range of kerosene jet engine airplanes?
What is the ratio difference for weight/performance/range when using batteries and electric engine instead of kerosene and jet engine?
Even if batteries are 10x less efficient than kerosene, can it still be useful for short range flights (maybe with half the amount of passengers), that's been my question for 5-6 years. Even when I tried asking Betrand Piccard (search Charbax Bertrand Piccard on Google) he didn't really reply, maybe he doesn't know.
