Hi, I have a question, why wouldn't this work: Imagine you have a two large parallel plates working as a capacitor with small holes in the center of the two plates. You put a potential over the plates. The electric field is then zero outside of the capacitor. You have Deuterium on one side and send in ionized hydrogen trough the hole of the other plate. The hydrogen will accelerate towards the opposite hole and smash into the deuterium on the other side making a nuclear reaction. No energy is put into the system, right? Where is then the kinetic energy given to the electron coming from? And why would not the fusion work?
