Description
The phenomenon of wire explosions under severe current surges of several kA (peak current) under several kV of applied voltage was known from the 60s from the first experiments of Nasilowski. A complete description in terms of Maxwell electrodynamics was though lacking until recently while Pappas, Graneau, Rambaut and Vigier were arguing about longitudinal current forces in the old Weber?s electrodynamics.
We showed that a perfectly rational explanation even below the fragmentation limit is possible in term of Maxwellian theory and provided a formula that was later used to exploit this effect in experiments with metallic wires and strips. Metallurgical microscopy showed the violent extraction of metal pieces during the first current pulses while signs of periodic ?burning? and zigzag like fatigue showed the role of stationary waves of low frequency around the main harmonic in the fast transient regime.
Molokov (2000) gave similar formulas including thermoplastic effects in very high voltage explosive experiments. Neutron emission was earlier reported in Vigier?s heavy water drill patent and experiments as well as in some other laboratories with Z-Pinch, X-Pinch devices that show the possibility of transmutations.
We currently examine the possibility of fine tuning of similar devices below the fragmentation threshold for energy production with an intermediate thermal stage. Appropriate ?fuel? is currently based on properly prepared alloys and compounds with a combination of light and heavy isotopes. It is hoped that careful simulations based on new techniques combining MD/FEM to include the electron cloud in the lattice may allow us to obtain a good approximation of the collision statistics from which any increase in the reaction rates of naturally active isotopes can be computed.
