The large high-energy lasers required for inertial fusion are at present beyond state of the art, and there are other problems (instability of the fuel target, suprathermal electrons, etc.) as well. Therefore, it is hoped that the energy requirement for inertial fusion can be reduced with the help of coldfusion, which takes place within the electrode material confining the fuel (avoiding instability problems). With the “semicold fusion cell,” laser energy is transferred into the “hot” part of the fuel, which is confined within the cathode in a cavity, and credit is taken from fast projectiles (tritium) stemming from the (t,p) branch of cold fusion in the “cold” metal lattice. The latter is the key to the model of a dynamic process for potential growth between the cold electrode and the hot confined fuel in the semicold fusion cell.
