Here is more from that wikipedia excerpt

Eliminating, for the moment, consideration of the extremely dense charge populations that exist in the upper reaches of the atmosphere, a region called the ionosphere, filled with hot, dense, plasma gas whose ions give the ionosphere its name, we note that there is always some amount of unbound positive and negative, but net positive, electric charge in the atmosphere closest to the surface of the negatively charged Earth on a ‘fine day’. When days are not so ‘fine’, the net unbound charge that exists in the clouds of thunderstorms can be exceedingly negative.

Commenter Naoki has a good suggestion pertaining to the video:

Hey Laser ever read the book called “electric universe’ by david talbott. The book basically talks about how it was electricity not gravity that shapped the universe into what it is today. The book also has tons of experiments, etc, proving their point. That book opens a door to alternative ways of energy production. Pretty cool stuff, thanx for all the work you’re doing. I’ll be working on stuff as well.

This is definitely fascinating and we hope this experimenter is onto something.  More eficient energy would be great!
