A thought came, different continents different current, the people on each continent have a different charge, their own electrical field is based on where on the earth they are.

As if we all held the same capacity of energy it could be a blanket system like the communications grid, but seeing as everyone builds to desired comfort it can't be.

So the electrical control system needs to alternate to cover more ground.

The "two great discoveries" to which Tesla referred, were:

1. The Dynamic Theory of Gravity - which assumed a field of force which accounts for the motions of bodies in space; assumption of this field of force dispenses with the concept of space curvature (ala Einstein); the ether has an indispensable function in the phenomena (of universal gravity, inertia, momentum, and movement of heavenly bodies, as well as all atomic and molecular matter); and,

2. Environmental Energy - the Discovery of a new physical Truth: there is no energy in matter other than that received from the environment.
