20100045037 | POWER GENERATION SYSTEM USING WIND TURBINES - A new wind turbines system extracts dynamic energy from ambient sources and generates power with high efficiency. The less-fluctuated slower-speed turbines have a high-ratio gear reducer to increase the high-power DC generator's speed. An analog/digital voltage converting sampler, a digital signal processor, a power battery charging/discharging regulator, and a power output in steady and continuous states meet its power generation safety and security requirements, which may produce power at about 50% efficiency. A power regulator stabilizes the fluctuations of the incoming power and regularizes its power outputs in steady and continuous states. A high ratio gear reducer (1:100=1:10×10 in two stages) increases its generator's speed and meets power generation requirements. The lower pole of larger blades' surface area using light-weight nylon fabric single-surfaced blade layer with strong angled strut support structure more efficiently converts power into electricity, and their conservation processes cut installation capital and maintenance costs. | 02-25-2010 |
20090044535 | EFFICIENT VAPOR (STEAM) ENGINE/PUMP IN A CLOSED SYSTEM USED AT LOW TEMPERATURES AS A BETTER STIRLING HEAT ENGINE/REFRIGERATOR - A high efficiency vapor (steam) engine/pump process in a closed system can use either water or liquefied gases for its working fluid to extract thermal energy from the ambient or non-ambient heat sources to increase its heat transfer rate and obtain power generation efficiency over 50%. A slow-speed two-phase piston engine's flywheel has a high ratio gear reducer attached to increase a generator's speed and produce power with over 50% efficiency and meet its power generation requirements (3,600 RPM). This two-phase engine/pump substitutes the cooling condenser's position, compresses the waste streams directly back into the boiler, and allows the process to run at temperatures lower than room temperature, with no need for a conventional cooling condenser. The present process will not discharge thermal pollution and/or radioactive/hazardous wastes into the heat sink and to the global environment, which is highly recommended for new nuclear steam engine modifications. | 02-19-2009 |
20080296906 | POWER GENERATION SYSTEM USING WIND TURBINES - The wind turbines system can extract the dynamic energy from ambient sources and generate power with high efficiency. The less-fluctuated slower-speed turbines have a main pump, a fluctuation-pressure stabilizer, a power generation water-turbines, and a high ratio gear reducer mounted together on the ground to increase its generator's speed and produce power at about 50% efficiency. A fluctuation-pressure stabilizer stabilizes the fluctuations of the hydraulic flow and regularizes its output to water-turbines in a single steady state, continuously. A high ratio gear reducer (1:1,000=1:10×10×10 in three stages) increases its generator's speed and meet its power generation requirements. The larger surface area of light-weight nylon fabric single-surfaced blade layer with strong angle strut support structure more efficiently convert wind energy into high-power DC electricity through the contacting/grinding reactions of a light-weight generator. Owing to these conservative processes, metallurgical material costs, installation capital, and maintenance costs are reduced. | 12-04-2008 |
