I suppose I should make a "sticky" out of my postings on this topic, since this keeps coming up...
Some years ago I was involved with a working-group on sustainable energy sources. We were quite thorough at investigating a wide range of technologies. Among them were technologies of the type that claim to produce usable energy from the zero-point field, and technologies that claim to provide over-unity output (more energy out than appears to go in), etc. etc. etc.
The bottom line is, despite extensive direct interviews with various people who claim to have working devices, and examination of their inventions, we didn't find anything that was reliable, repeatable, and scalable to a degree that would provide a practical source of power.
Most of the people who are working in this area are sincerely motivated. Of those, most are self-taught and a few have conventional educations in their fields. A few are scammers, and these have had a disproportionate impact. Innocent engineering mistakes were commonplace; we didn't find much overt cheating; we did find occasional examples of devices that seemed to do "something interesting" but not in a reliable manner. We also found that some of the "mistakes" had potential in a more conventional sense, e.g. incremental improvements in the efficiency of common devices.
I could go on for another page or two about this stuff, but look up my postings on zero-point energy for more.
Personally I think the zero-point field theory has interesting potential as pure science, i.e. it does have elegance in explaining inertial mass. And some of the other work going on in anomalous energy sources may also lead to interesting discoveries in pure science. However I'm not convinced that any of this will lead to practical applications any time soon.
Aside from which, we do have nuclear fission and wind power right now, and plug-in hybrid electric vehicles, and a range of other technologies that can improve efficiency. And photovoltaics are improving every year. We should be using the technologies we have right now, rather than holding our breaths to wait for a breakthrough that might or might not ever occur.
