Are you refering to weather control and the ability to creat earthquakes, etc? . . .
Yes, IF TRUE, those would be rather sobering.
I don't know what's true about Tesla's stuff. But I'm convinced there are some exotic technologies that arose out of his work and that are already deployed and have been deployed for some time.
It is more than a little interesting that at least one of the group of scientists who have successfully predicted some serious quakes--one group has a prediction hanging out between now and 5 Sept--they also, at least one group--evidently uses the concept of scalar waves as Tesla did.
I think some of the discussion of Yellowstone's huge volcano and related quakes has also involved scalar waves.
And, there have been dreams of some Christians which seem to 'observe' future activation of some such technologies in a war context. No, I don't have those refs or links available. Just one of those bits of puzzle pieces logged in my gray matter.
