How much electricity is in a lightning bolt?
Harvesting lightning energy
{'answer_start': array([-1]), 'answer_text': array([''], dtype=object)}
A technology capable of harvesting lightning energy would need to be able to rapidly capture the high power involved in a lightning bolt. Several schemes have been proposed, but the ever-changing energy involved in each lightning bolt renders lightning power harvesting from ground-based rods impractical – too high, it will damage the storage, too low and it may not work. Additionally, lightning is sporadic, and therefore energy would have to be collected and stored; it is difficult to convert high-voltage electrical power to the lower-voltage power that can be stored.[5]
