I admit I did not expect to see such a study show such an opportunity existed in this timeframe, but the logic appears sound when I read it.
If indeed there are flaws in the calculations I am very interested to know more.
A quick calculation using the numbers in the article as to range, passengers, and battery energy density, suggests a battery to fly 800 km would mass about 33,500 kg. This does not include any reserve; with a 200 km reserve the mass is about 42,000 kg. One aspect of battery power is the landing aircraft weighs the same as the takeoff craft (with a tiny loss due to quantum effects that I will ignore). The kwh/passenger/km and energy density numbers also seem to be optimistic.
