Tesla's Electrostatic Propulsion System:
"In Tesla's Wardencliffe design, the top capacitance was chosen such that it could contain the entire charge developed in the secondary. Instead of breaking out to produce lightning bolts, the entire charge was discharged back through the secondary and into the ground. This would cause a very large wave to propagate around the Earth.

Tesla further remarked that he could make these standing waves appear at any place on the Earth by building and controlling other power stations and using a type of triangulation system. In theory, Tesla could make the standing waves all peak in one particular place, causing who knows what kind of effects?"
