We know how to attract them, how to drive them to the ground, why can't we store them? Batteries are too weak to hold it on? A too big diode should be needed to transform it in electricity?
What do you mean by "strikes" ? Can you elaborate a little?
Fred Romano ,
Interesting question. Ignoring the previous two comments (discussing the meaning of the word "strike"), I think it comes down to practicality.
Batteries certainly are not suitable. Supercapacitors of the future may well be. It comes down to problems involved with transferring and storing such a huge amount of charge in such a small period of time .
Typical values (negative) are as follows:
30 kA, 15 C up to 120 kA, 350 C
500 MJ to 5 GJ of energy
30 ms typical duration

Yes. current and probably the near future batteries are too weak to store the instantaneously generated extremely high energy in lightening.
