DigInfo – (movie.diginfo.tv) Previously known as Mecaro Akita, The Mecaro Company, now a producer of wind turbines, exhibited a model of the wind power generating Spiral Magnus at the Venture Fair Japan. The Spiral Magnus uses cylinders instead of flat blades to produce power and is thus quieter, safer and provides more power than flat blade wind turbines. The Spiral Magnus’s design is based on German physicist Dr. Magnus’s theory in which the wind velocity and pressure changes as it passes around the cylinder causing a lifting force that spins the cylinders similar to the motion of a baseball. With the spiraling fins surrounding the cylinder to catch the wind, four times as much dynamic lift is created as wind turbines with flat blades. In a wind speed of 6 meters the Spiral Magnus can produce 30MWh annually which can provide for 9 average households. The Spiral Magnus can withstand winds of up 50m/sec which are only commonly found in the polar regions. The product seen here is just a smaller replica of the actual Spiral Magnus which has a propeller diameter of 11.5m and stands 12.5 tall to the center of the propeller. Due to its safe, slow rotation speed the Spiral Magnus can be placed anywhere.

Here is my analysis of 3 and 4 bladed turbines. I sometimes heard of the question of 3 vs 4 blades on traditional windgenerators (HAWT) and even helicopters and airplane propellers …so the question is now what can be the difference of using 3 or 4 blades on a VAWT. This video is about what I currently thought up. With the 3 bladed turbine, the blades receive more uninterupted wind force as it rotates. At a certain angle the wind force will begin to get interrupted by another blade, and at another certain angle, the wind force is completely interrupted by that blade. The most basic fact is obvious, that the angular sepeartion of the 3 bladed system is 120 degrees and the angular sepeartion of the 4 bladed system is 90 degrees. When the blade is 90 degrees perpendicular (a right angle) to the wind max. wind force is upon the blade due to the large surface area. From this point, with the 3 bladed system the blade can rotate 60 degrees before being completely “blocked” by another blade. With the 4 bladed system, the angle is only 45 degrees. The only advantage of the 4 blade system that I can think of right now is that the blade perpendicular to the wind happens slightly more often per revolution with that system; providing another quick “pulse” of force and the corresponding pulse in rotational speed and torque of the turbine at this point. You might ask… What about a 2 bladed turbine system with the blades seperated by 180 degrees? Each blade will receive “more time in …

Wind Turbine Fire. Wind power drives a wind turbine generator to make electricity, but judging from the number of wind turbine fires and other wind turbine accidents reported on YouTube alone, the wind turbine manufacturers must be having a field day replacing all the wind turbine units in farms specially built for wind turbines. On Christmas Eve 2005, a wind turbine generator at the wind turbine farm of Nissan car plant in Sunderland caught fire at the top of one of the wind turbines, and the flames, fuelled by wind power, rapidly spread to the Wind Turbine sails before finally burning out. Both lanes of the nearby A19 trunk road had to be closed to traffic because of the danger caused by the wind turbine fire, and the other wind turbines were stopped. The towers of the wind turbines are 200 feet high to catch the maximum wind power, so the wind turbine generator was not accessible to fire crews. Eventually, all 3 of the 75 foot long blades of the Wind Turbine, or what was left of them, dropped off. The central power pack of the wind turbine generator at the top of the Wind Turbine mast is thought to be the cause of the fire, and these wind turbine accidents are not uncommon. The 6 wind turbines were bought second hand from German wind turbine manufacturers, and there are many reports of wind turbine generator fires on the Internet. Wind turbine accidents and wind turbine fires in the wind turbine generator units at the top of wind turbines in The Netherlands, Palm …
