Oh, so we are all going to get free lectures in super over the horizon GR math. Nice. So basically what @waitedavid137 is talking about is darling of conspiracy theorists, like us, Biefeld–Brown effect, that had been widely documented. Brown was sponsored by US Navy to perform large number of experiments in their laboratory, both under atmospheric pressure and strong vacuum. And it was claimed that experiments were success. Brown even went so far to refuse an interview on the basis that he signed non-disclosure-agreement with a company that purchased intellectual property rights and couldn't speak on the subject. That is in spite of the later NASA's experiment on the same topic, that was deemed failure, which was possibly just a coverup. Videos do systematically get removed from youtube, so watch this soon. Here you can see Brown lab inside Navy's facilities, where he experimented with electrogravitics. Non-scientifically speaking, purely on human level, it remains a mystery what were T.T. Brown and his team celebrating with bottle of champagne? Was it possibly a reaching their intended goals with experiment? Unlike NASA that only went up to 40 kV, T.T. Brown went up to 200 kV.
