Electric field can easily create plasma at tips. Effect known as St. Elmo's fire. If material have impurity in the form of a tip in a cavity, then an electric field can create plasma in this cavity.

No, it cannot. There is not a single instance reported of spontaneous plasma formation in a defect in a crystal, charged or otherwise. The electric field within a conductor is effectively zero: you cannot have the kind electric field required. This would be very easy to see if it were happening: the brutal expansion of the plasma would create huge stresses and its high temperature would melt the material locally. This is just not happening. You are also moving the goalposts again: there is no such thing as protons getting accelerated by a MeV just by interacting with defects; the mass of a proton is irrelevant; and you don’t have spontaneous plasma in a crystal. Nothing you’ve written in this thread is supported by reality.

This is just not happening. Local melting reported from the beginning for 20+ years. Quotes: Occasionally, energy density is sufficient to cause local melting.[87] Melting is possible because many impurities lower the melting point well below that of pure palladium (1554.9°C).[105, 106] In the course of these experiments, the Japanese researchers verified the existence of other phenomena frequently reported from cold fusion experiments, such as occasional releases of energy in the form of sharp bursts. Formation of small craters on the surface of Pd cathode during electrolysis in electrolytes based on heavy water is sometimes interpreted as a consequence of low-temperature nuclear reactions. In this note we discuss the validity of these statements. And so on.

    I see, A Student’s Guide to Cold Fusion. That is cute. And now the goalposts have moved from spontaneous melting to local melting under an electric field. Reference 87 does not support melting in any way (you don't get faceted voids from local melting, and yes, local melting is a thing, just not spontaneous at room temperature with unaccelerated protons). References 105 and 106 have nothing to do with melting. It is not difficult to find references (I mean, real ones, not dodgy conference proceedings) showing that defects can lower the melting point of a metal under certain conditions. But lowering the melting point does not make melting happen on its own at room temperature, either. And even if you can demonstrate that there is some melting, rather than an electrochemical reaction, it does not mean that any fusion reaction happened. It's about as credible as blaming aliens for a pattern you see in the noise. > Formation of small craters on the surface of Pd cathode during electrolysis in electrolytes based on heavy water is sometimes interpreted as a consequence of low-temperature nuclear reactions This is bunk. The Earth is sometimes referred to as a disk; it does not make the flat earth argument sound, particularly if the people doing the referring are the same people building a case out of it. Again, none of this makes any sense, you're just wasting your time.
