Abstract

The 40 KHz piezo reactor input exposes the 5×5×.01 cm ³ foils to a controlled pulsed transient cavitation bubble, TCB, process with a peak acoustic input of one watt/cm³. These TCBs are considered micro plasma accelerators. During its pseudo-adiabatic collapse a bubble jet is formed which accelerates a dense coherent plasma into a target foil. The pulse duration of the D ⁺ injected into the foil lattice during an acoustic cycle is a few pico seconds. In the target foil anomalous heat, Q(x), is formed and produces as much as 15 watts over the 10 watt acoustic input. Calorimetric measurements of Q(x) use Newton´s Law of Cooling where watts in equals watts out
