The big surprise, if one believes that a version of the Mills hydrino/deuterino is involved at a fundamental level in all of LENR, would be the appearance of EUV.
Unfortunately this radiation spectrum is "universally absorbed" by every element in the periodic table, so you would need to somehow incorporate the detector into the electrode itself. Mills uses a pinhole detector. -----Original Message----- From: Abd ul-Rahman Lomax If we are looking at an active surface, what will we see in the visible and near-IR?
