Abstract: On génère et accélère contre l'électrode négative des deutérons libres, noyaux lourds d'hydrogène, possédant une énergie cinétique élevée, par un procédé de décharge électrique à haute tension, s'effectuant, sous forme d'arc ou d'étincelles, entre des électrodes métalliques (2, 3) immergées dans de l'eau lourde, D2O. On décharge les deutérons sur l'électrode en captant des électrons et en créant des atomes D et des molécules D2. Lesdits atomes et molécules sont absorbés sur la surface du métal, présentant ainsi une cible à des deutérons incidents, de manière à réaliser des réactions nucléaires et une fusion de noyaux d'hydrogène. Dans une réalisation, l'électrode à haute tension (3) est installée entre la cathode (2) et l'anode (13), créant ainsi une cellule pour l'électrolyse de l'eau lourde. La cathode (2) et, plus particulièrement, la couche superficielle seront saturées de D2, ce qui augmente considérablement la probabilité pour des réactions à fusion des deutérons générés par des décharges, s'effectuant par intervalles, entre la cathode (2) et l'électrode à haute tension (3), et heurtant ladite cathode. On peut récupérer, sous forme de vapeur à haute pression, l'énergie de fusion ainsi déclenchée, ainsi que l'énergie électrique d'alimentation.

Inventor: NELSON NED
IPC: E02D29/02
Filed: 1990-06-18
Abstract: A lightweight, pre-cast, reinforced, module used to build a structurally engineered retaining wall system. Each module has a panel with a front and rear surface with at least one horizontal reinforcing rod. In the preferred embodiment, a portion of each rod horizontal transverse an integrally attached flange located at each opposite end of the panel. On the outside surface of each flange, there is a recess across which a portion of each reinforcing rod is exposed to be subsequently surrounded by concrete of a poured-in-place reinforced column. A horizontal row of adjacent modules is positioned on a constructed, reinforced footing. The front surface of each module is exposed and each flange is positioned opposite to a flange located on an adjacent module with a column space created between opposite flanges. Alignment elements are attached to the upper surface of each flange and successive horizontal rows of modules are then positioned above until the desired height is achieved. Vertical column forms are attached to the distal and proximal edges of opposite flanges and concrete is poured down into the column space and surrounds all the exposed surfaces. After the concrete has cured, the column forms are removed and the retaining wall structure is completed.
