But if you are 100km away from your airfield, especially if you
used your battery for take off, there will be little or no use of
FES.
I like the idea, but sorry, with current Li-ion batteries with max
150Wh/kg, this is not very promising technology. I am waiting for
Li-S, or Li-Air cells, then we can talk seriously about FES.
