eli5 why we can’t collect energy from lightning ?

995 views

Saw lot of videos and it seems pretty easy to push wire to thunder clouds to make lightning hit exactly that wire. Why not put some sort of big ass super capacitor and collect this free power for sake of humanity?

It is not free power, and there is not much in there either. There is an enormous difference in potential, which is ionizing the air and allows lightning to happen.

The issue is also that all the energy is sent instantly, which means you need some kind of storage device than can convert that massive potential (ie. voltage) into something more usable and storage, and do that fast since lightning is over pretty fast. This device does not exist. A “big ass supercap” will likely explode, or be so big you’d waste way more energy placing it where you think there will be lightning than it will ever collect.
