摘要： The disclosure relates to a plant, especially power plant, for reduction of the carbon dioxide content in atmospheric air, especially for improvement of atmospheric air quality. The plant has at least one electrolysis unit for oxygen production, at least one carbonization unit for carbon synthesis, especially a Bosch reaction unit, and at least one unit for cleaning of ambient air from an outside atmosphere surrounding the plant. The carbonization unit synthesizes carbon from carbon dioxide which is obtained from the atmosphere by means of the carbon dioxide sorption unit and this carbon is stored, in order to effectively reduce the proportion of carbon dioxide in the atmosphere. The disclosure further relates to a method of operating such a plant, with which the carbon dioxide content in the atmosphere can be efficiently reduced.

摘要： Oval, rounded or circular electrolytic cell designed for use in internal combustion engines that produces hydrogen/oxygen gases from water through an electrolysis process made up of at least seven oval metal plates and closed within two closing seal blocks, upper closing block (4) and lower closing block (6), made of non-conductive material such as plastic and rubber-type materials; where the five central plates are neutral electrolytic plates (1) and the plates at the two ends are the anode electrolytic plate (2) and the cathode electrolytic plate (3) and they are connected to current by means of two electrode cables (8) protected by a cable insulator (9) and at the closures they have lower electrolyte inlet slots (7) and other upper gas outlet slots (5), which, given the oval design of the cell, allow the gases generated during the electrolysis process to easily escape through the top openings and the electrolyte to easily and continuously replenish in each cell through the lower openings.
