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 30 MWh el...

Is the water ball left in the air? This short movie is amazing. This extremely slow and detailed motion pictures were reportedly taken with Photron's high speed video camera at 4,000 frame per second. Photron , a Tokyo based company, offers a series of high speed video cameras to manufacturing industries, the medical field, film laboratories, television and movie studios, as well as to the military worldwide. According to the company's web-site, Photron seems to be engaged in developing and supplying advanced image processing systems. Going into the broadband network era, high speed and high resolution images will be demanded and become more popular not only for industrial analysis but also for new discovery and even for pleasure. 2/28/08

Spherical shape of a solar cell sounds unique and unparalleled in its capability to achieve a better conversion rate between solar energy and electricity than the conventional flat cell. In fact, the sphere, because of its own shape, must be ideal to absorb direct and reflected lights while a flat one can't take the reflected light from the reverse side. The production process, Kyosemi Corporation , the manufacturer of the solar cell, seems to be also incomparable to dramatically reduce wasted material of silicon. The spherical solar cell, Sphelar ®, is just one millimetre in diameter, seem to have great potential for varieties of application. One of the new applications, Kyosemi supplies, is SphelarVoice ™, a battery-free wireless audio optical information system using Sphelar ® cells. I've found a good video movie on YouTube that resents the uniqueness of these points. It's should be better than a lengthy description in writing. Seeing is believing. Take a look at th...
