Hi, In QM tunneling is a somewhat mysterious mechanism. I propose the following possible mechanism for fusion based on the ZPF.
1) If two nuclei are close enough, then the nuclear force may bring about a fusion reaction. 2) The ZPF jiggles particles. 3) The ZPF comprises a mixture of waves at different powers. 4) The more powerful a wave is, the more rare it is. 4) The further apart two nuclei are, the longer you have to wait for a wave to come along that is powerful enough to jiggle them hard enough to come within fusion distance.
