The more likely route is the same as that used in quantum cascade lasers. In these systems, electrons tunnel from one location to another with almost the same energy. But in their new location, they quickly lose energy (via an acoustic wave generated by the crystalline material that holds the electrons), which traps them there. This is an actual mechanism based on well-established physics. It does, however, rely on very specific material properties and precise structural engineering. Given that, it’s probably not what would happen in the proposed device, either. If you measure, you get numbers Nevertheless, the company claims to have made a device and measured a drop in voltage between the plates and pillars. The company also claims this voltage is predicted in a paper that doesn’t appear to have any predictions, which is necessary for success. I would be shocked if Casimir, Inc. had not measured a potential difference. For a decade, surfaces of materials were the bane of my existence.…
