Spiral Magnus

Quieter and safer wind generating turbine with a better wind load survival rating sounds great, and in fact the outward appearance of the newly announced wind turbines, Spiral Magnus, looks lighter than the conventional blade type of wind turbines, while the new machine cylinders instead of flat blades to produce power is thus reportedly quieter, safer and provides more power than flat blade wind turbines.

Attached, is one of video movies available at YouTube site, and the description of the video movie says, "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." According to the description, the Spiral Magnus can generate 30MWh electricity annually at an overage wind velocity of 6 meters/second, and can survive at a wind velocity of 50m/sec.



There have been just a few wind turbine manufacturers in Japan while most of them are in the heavy electric machine suppliers. Mecaro is the name of the company that have announced the new wind power generating system of Spiral Magnus. I do hope that the company will make a big contribution to reducing CO2 on the earth.
