Lightning strike harvesting

Dig
Dig over 14 years ago
Is it possible to capture the electrical energy from a lightning strike?
Since a strike is so brief, what would a good strategy be? Lifting a weight with a solenoid powered by the strike itself?

    The amount of power in a single lightning strike is not as big as many people think.

    The danger from lightning is that the power it is released in a short time.

    Compared with gasoline, you can create a huge explosion with a spoon of gasoline, but if you put it in your car it will not bring you very far.

    The second problem is to catch many lightning strikes. Thunderstorms don’t stay very long at the same place. Only some buildings on top of a hill are hit more than once during a thunderstorm.

    So you need equipment capable of handling high peak powers while the amount of power you could catch is low.
