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.

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.
