No, it could not. The physics of evaporation are well understood and can be modeled and tested in detail. Evaporation is governed by temperature, and the electrolyte temperature is measured precisely. Experiments producing no excess heat sometimes have more overall power output (from higher powered electrolysis) than the experiments that produced excess heat, but the water level change was exactly as predicted by conventional electrolysis. Conventional evaporation and electrolysis are well understood. They do not suddenly and inexplicably produce 5 cc changes instead of 0.5 cc. Open cell electrochemistry has been done for well over 100 year. Also, Miles uses other reliable methods to confirm the flow of gas is as expected, for example capturing the gas in an inverted, water filled test tube. - Jed
