I don’t have time for a long exchange on this topic, but just glancing at the EU website, it does not seem that this is a quantitative theory that makes quantitative predictions that can be compared with observation. Our work on FF is based on quantitative theories of electromagnetism, quantum mechanics and nuclear reactions that have a huge amount of experimental validation over the past two centuries. Of course new physics can and will be discovered. But to prove it, you have to reduce a theory to a quantitative form to compare it with observation.

There are certainly things in EU that seem to contradict much of what we know of electromagnetism. If the Sun and other stars are positively charged, why don’t they get neutralized? A circuit has current flowing in and out of all points, but EU seems to hypothesize a flow of current indefinitely outward from a point—which is way different than what Maxwell’s equations describe and what we observe in the lab.

It also is different that what the SAFIRE experiment seems to be talking about, which is a circuit that is supplying current from the outside to an anode on one side of a chamber and it flows through a plasma to the cathode on the other side.

Really it is not possible to discuss this stuff at all unless someone publishes some quantitative results with some quantitative theory —even self-publishes.
