I have read testimonials from people who have visited the Christian Community Methernitha in Linden Switzerland, wherein they claim to have witnessed the famous Testsatika machines in operation, though without much explanation from the inhabitants. I have also read that often the "cold electricity" created by "radiant energy" machines (Moray's term)which draw upon ZPE, while they creates a current that easily and quickly powers resistive circuits, the voltage and amps are undetectable with conventional measuring devices. It is likely that PROVING such tecnologies' efficiency and possibility will be difficult until a complete paradigm shift sweeps through, or at least leads to an explanation which can reconcile modern physics enough to force acceptance. I see on the site that there exists no PROOF of any of these ZPE machines... yet, while I haven't wandered to switzerland for verification, if it were true that this entire community powers itself with a free energy device, what more would true proof consist of? Does anyone here have an idea for how to verify such claims? Also, any thoughts on why proving has to always be a process of nearly infinite failed attempts at disproving?
