I know Tom's site https://cheniere.org for a long time. It is a good collection of interesting devices and ideas, but none of that devices was reproduced successfully, i.e. for generating energy in self-sustaining mode. We have Russian site https://x-faq.ru/ with forum where ordinary people trying to replicate any non-conventional device from free energy and antigravity generators to medical devices and vortex things and people really discussing the problems and results of their real experiments. There are tons of information, circuits, photos, descriptions on any possible "forbidden device", unfortunately in Russian only. But if you really interested in non-conventional devices, especially if you going to replicate one - this is definitely place to visit, discomfort with online translators worth it.
