What is the status for electric passenger airplanes?
If the kerosene jet engine airplane does 20 hour 900km/h range carrying 300 people.
why can't:
battery electric engine do 1 hour at 600km/h carrying 100 people?
What is the power/range/weight ratio difference between a kerosene jet engine airplane and a potential electric battery propeller airplane (no electric jet engine?)
If kerosene is 20 times more powerful per weight/size compared to battery electric engine, then why can't we "simply" use battery electric engine powered airplanes for all short ranges? Until battery capacity improves, recharge cycles increased and range can evt be extended.
The batteries can be charged from clean energy using wind, solar, thermal and even nuclear.
