One of the most popular misconceptions, says engineer Richard Cochrane from Exeter University in the UK, is that all vertical axis wind turbines are silent, or at least less noisy than all of their horizontal counterparts on large wind farms. In some cases, those stories may be overstating their potential, or using outdated information to present an inaccurate portrait of them. The Internet is littered with websites for now-bankrupt companies, proclaiming the glory of these machines and their capabilities, as well as an almost endless list of enthusiastic articles, often full of myths about them. There is, however, an abundance of people willing to experiment, sometimes via shaky financial backing, with the emerging turbine technology. And although enthusiasts claim that the smaller vertical turbines don’t kill flying animals such as birds, there has not been a great deal of data gathered yet about their overall impact on wildlife. Many questions remain unanswered about how much energy a small vertical turbine on top of a building can produce. There also aren’t enough of these machines being produced commercially to bring down the price, which remains stubbornly high-in some cases running into tens of thousands of dollars per unit. Not enough is known yet about how long the equipment will last, and there’s not always a solid guarantee of return on investment. There hasn’t been enough research to make vertical turbines durable and affordable, Preus points out. “The question is whether or not you can do so competitively.” “You can make a that will produce electricity,” says Robert Preus, a researcher at the National Renewable Energy Laboratory in Colorado who helped develop certification criteria for small wind turbines in the U.S. Some private firms worldwide have begun integrating vertical axis turbines into architectural plans for commercial buildings.īut vertical turbines have also attracted a sizable number of skeptics and naysayers. Paris has embraced the notion with enthusiasm, even allowing two giant turbines of this type to be installed within the steel latticework of the Eiffel Tower, which might someday generate enough electricity to power the ground floor of the tourist attraction. In many large cities, including New York, San Francisco, Boston and Chicago, city officials and scientists have been studying vertical axis turbines and contemplating their use. Most are also relatively small, and unlike horizontal units, they can be grouped very closely together to optimize efficiency. And unlike their horizontal brethren, the components and associated generators of a vertical turbine are placed at its base, giving it a lower center of gravity. There is no single design for these upended wind catchers, but all share one key aspect: the blades turn around an axis that points skyward. But in the last two decades, a flurry of interest in expanding renewable energy in cities has attracted the attention of a large number of inventors and artists, many of whom see the vertical axis wind turbine as promising. The idea isn’t a new one-people have been playing with windmill designs and experimenting with alternatives to the horizontal axis turbine for almost a century now. Branded as noisy, blamed for spoiling bucolic views and proven deadly to some bats and migrating birds, the giant, white-bladed horizontal axis wind turbines that now dot the landscape of the American West have earned a fair number of detractors-even among environmentalists who generally favor renewable power.īut what if you turned the idea sideways, and created a turbine that could spin like a carousel? And what if you made a turbine small enough to sit on top of a building or inside an urban park? Could the result produce enough power to really matter? *Our wind turbines must be installed following their user manual and operate under ideal weather conditions to reach their maximum power generation.Although a lot of people are excited about wind energy, few are excited about the pinwheel-shaped machines that often produce it. The mounting of the wind turbine is carried out easily via a plug connection and into a pole. Very durable yet lightweight with a quiet operation mechanism.Ĭan also be combined with TESUP Flexible Solar Panels.Įasy and quick installation, approximately 40 minutes. Ability to operate at very cold temperatures (up to -50☌). Rotation starts at 3 m/s wind speed, then rotates smoothly and freely.Ĭorrosion-resistant superior carbon fiber body. Our smallest and most compact horizontal design with the lowest starting wind speed: Master X can generate up to 1 kWh of electricity per hour.* It is designed and manufactured by TESUP, World's leading household wind turbine and flexible solar panel manufacturer.
