Households can now make use of wind power technology by installing micro turbines, also known as or small-wind or 'microwind' turbines. Special marinised wind turbines are available for use on boats. These can achieve acceptable efficiency and the rpm is better too. Perhaps it will be like nuclear: large stations will prove uneconomic, but maybe lots of little ones might work. Their efficiency is dismal. Pitch control on a VAWT will have to work very hard as it moves with every revolution. kind regards Michael. Normal wind turbines have lift forces that push them downwind all the time: constant direction. I am sorry if my argumentative tone is upsetting, but I am genuinely angry and sad that people are taken in by the unsubstantiated claims of vertical axis enthusiasts, often well-meaning, who have no actual experience of wind energy.
