An ambitious project to re-create an amazing electrical effect that's only been observed in natural lightning... until now.

Totally awesome, Greg, this is a great project. There's about 100 GW of lightning power continuously flying around in the waveguide formed between the earth and the ionosphere. The global Q is about 10, so the power circles the earth up to 10 times in spherical Lengendre oscillations before dying out with a fundamental frequency of about 7.83 Hz, called the fundamental Schumann Resonance . If you trigger your lightning with this device, you may be able to detect the spherical (global) waveguide echo 127 ms later when the lightning pulse has circled the Earth one time. Most of that energy focuses right back where it started after circling the earth once. An even stronger signal should be detectable at the antipodes of your experiment, so locate your experiment carefully so that the antipodes are not in the middle of the Indian Ocean and try to measure the lightning signal at the antipodes as well!
Awesome project. This has to be built!
First! Good looking video.
