You're making an "experiment conclusion communication" with no experiment to conclude. What experiment was performed? None. A hypothesis for an "experiment conclusion communication" without an experiment. If you're Keen on a "gravitational energy- harnessing machine", make it. Or, study energy yourself without riding on the back of a book proposing conspiracy theories. You've put forth a claim with no evidence but a book you've read. You've cited your evidence by the same book. Let me tell you; no one knows for sure how gravity is produced. There's theories all the way down to a partical for it's interactions (graviton). Pick up a text book, and any of them will cite this same conclusion. If you wish to metaphorically build a theoretical car without knowing the mechanics of the motor, then I wish you luck. If you insist this is possible, do it. Stop wasting your time explaining something, put your Harvard degree into action. Until then, I'll continue my studies of the practical findings of physics, not wishing to build a house before I know how to pour concrete. Continue to preach free energy machines if you like, but it's my hope that everyone here is sensible enough to know that a generation struggling immensely with the creation of fusion energy isn't bothered with creating a generator that runs on unsubstantiated books, poor grammar, and leaps of theory.
