Abstract

In a static electricity generator (1) operating at high efficiency at low temperature difference a semi-permeable membrane I (2) is located between two solutions (3, 4) having different boiling points, whereby one of the solutions features a water-absorbing capability. While the water evaporates from the low boiling point solution (4) the temperature of the water-absorbing capable high-boiling point solution (3) rises by absorbing the water vapor. Heat transfer (5) and water transfer (2) as per the principles of osmosis are realized between the two solutions. The evaporated water (6) expands and is liquefied in a condenser (7) and is evaporated again by expanding (9) to a reduced the pressure (11). The condensing heat is transferred (10) to the evaporating water at reduced pressure. In order to prevent irreversibly increasing heat blocking the system, some heat is released to the environment (8). Evaporation at low pressure draws heat from ambient temperature or from the upgraded medium at elevated temperature raised by any heat source (12). Water vapor is transferred (13) to the water-absorbing capable high-boiling point solution (3) and condensed (16) after mixing with the solution. From the water-absorbing capable high-boiling point solution (3) to the solution not having water-absorbing capability featuring lower boiling point at the same pressure, heat transfer (5) and water transfer (1) as per the principles of osmosis are realized and completes the cycle. Electricity is produced by a thermoelectric generator (18) by the temperature difference and heat transfer from the water-absorbing capable high-boiling point solution (3) to low boiling point non-absorbing water solution (4). Generated electricity can be converted to the required electrical voltage output by converter and inverter circuits (20) thereby producing usable electricity (21).
