Hi @mage00000 ,
I am still a bit curious and trying to understand what I've got so far.

Just want to make things clearer. In conclusion, this TMT harvest energy mainly through giant streamer's spark like giant tesla coil does?

And then transmitted through the earth?
(Knowing there's not much resistance.. and the energy added from earth charge while travelling back and forth can neutralize that resistance)

I've read also about safety. But it's still scary tough seeing blazing spark like crazy over time. (or it's not?)

These series was really interesting, even for no-science guy like me.

HUGE THANKS!!
