Alternate Interpretation of the Original Fleischmann and Pons Experiments

Authors: William L. Stubbs
Comments: 8 Pages.

A case is made for the fusion reactions apparently occurring in the original Fleischmann and Pons (F-P) experiments to be the result of free D+ ions formed at the anode during electrolysis colliding with deuterons trapped in the Pd lattice of the cathode, rather than trapped deuterons being squeezed together by the lattice. The data from the experiments show that the energy output of F-P cells was essentially proportional to the energy input, independent of the cathode size or the current strength, which implies that the cathode plays a passive role in the energy production. The number of D+ ions produced at the anode and their velocities are proportional to the current used in the cell, so that the number of D+ ions that survive the trip across the gap between the anode and the cathode is greater for greater currents. The larger numbers of D+ ions from the higher currents result in more collisions with trapped deuterons in the cathode producing more energy.

Efficient Energy Conversion of the 14MeV Neutrons in DT Inertial Confinement Fusion

Authors: Friedwardt Winterberg
Comments: 10 Pages.

In DT fusion 80% of the energy released goes into 14MeV neutrons, and only the remaining 20% into charged particles. Unlike the charged particles, the uncharged neutrons cannot be confined by a magnetic field, and for this reason cannot be used for a direct conversion into electric energy. Instead, the neutrons have to be slowed down in some medium, heating this medium to a temperature of less than 103K, with the heat removed fom this medium to drive a turbo-generator. This conversion of nuclear into electric energy has a Carnot efficiency of about 30%. For the 80% of the energy released into neutrons, the efficiency is therefore no more than 24%. While this low conversion efficiency cannot be overcome in magnetic confinement concepts, it can be overcome in inertial confinement concepts, by surrounding the inertial confinement fusion target with a sufficiently thick layer of liquid hydrogen and a thin outer layer of boron, to create a hot plasma fire ball. The hydrogen layer must be chosen just thick and dense enough to be heated by the neutrons to 100,000K. The thusly generated, fully ionized, and rapidly expanding fire ball can drive a pulsed magnetohydrodynamic generator at an almost 100% Carnot efficiency, or possibly be used to generate hydrocarbons.

Matter-Antimatter GeV Gamma Ray Laser Rocket Propulsion

Authors: Friedwardt Winterberg
Comments: 14 Pages.

It is shown that the idea of a photon rocket through the complete annihilation of matter with antimatter, first proposed by Sänger, is not a utopian scheme as it is widely believed. Its feasibility appears to be possible by the radiative collapse of a relativistic high current pinch discharge in a hydrogen-antihydrogen ambiplasma down to a radius determined by Heisenberg’s uncertainty principle. Through this collapse to ultrahigh densities the proton-antiproton pairs in the center of the pinch can become the upper GeV laser level for the transition into a coherent gamma ray beam by proton-antiproton annihilation, with the magnetic field of the collapsed pinch discharge absorbing the recoil momentum of the beam and transmitting it to the spacecraft. The gamma ray laser beam is launched as a photon avalanche from one end of the pinch discharge channel.
