Diarrhea Gastroparesis






The idea of \u200b\u200bharnessing wind power to generate a rotary motion is centuries old, first cousin of the water wheel technology.
The main advantage of the exploitation of wind energy is a never-ending source of energy and totally free and a limited environmental impact given that the design factor is not required dams and channels as it does for the hydro plants.
The limit of a wind turbine is the reduced air density that generates limited power in the size of the wind turbine. To get an idea of \u200b\u200bthe relationships in play enough to consider that the air density of approximately 1,225 kg / m, is related to 1 / 816 compared to average water.
It so happens that an output of 1 MW represents more or less the lower limit for the applicability of a hydraulic turbine is a power but very respectable for a wind turbine.
The operating principle of a wind generator is more or less well known. A system of blades, placed in rotation by the energy of wind, which generates a rotary motion, through appropriate mechanisms, is transmitted to an electric generator.
If you look at a wind turbine, especially in photography, where you lose the effect of imposing tower of support and the huge blades spinning, you have the feeling of being faced with a quite boring machine, a variant of the windmills that survive in the world with tourist purposes only. In reality the technology used to design and build a wind generator is taken directly from engineering and sophisticated avionics. The writer has worked for more than three decades in the field of mechanical design in various fields, including engineering of hydraulic turbines, and can say that the design of a wind turbine business is of great satisfaction and commitment.
