movie.diginfo.tv DigInfo News Embracing the move towards renewable energy sources, Kyosemi have revolutionized the design of the traditional solar cell, increasing it’s power generation efficiency and paving the way for innovative applications and a more economical use of raw materials. Sphelar is a spherical micro solar cell, which unlike traditional flat solar cells, can effectively harness reflected and diffused solar light as well as direct light from all directions. Each cell, is 1 to 1.5 mm and can be connected in parallel or in series, allowing for a limitless range of shapes and uses including flexible solar cells, round solar cells, or power-generating windows for buildings or offices while maintaining a certain level of transparency. Also, compared to the production process for traditional solar cells there is a dramatic reduction in the amount of wasted silicon. “In the process of producing spherical spolar cells, molten silicon is used. It’s dripped from an elevated position, and crystallizes as a sphere in mid-air, so using this process no silicon is wasted in the production of solar cells.” Kyosemi have also developed the SphelarVoice which is a battery-free wireless audio optical information system that receives information via infrared rays. The SphelarVoice uses an array of LEDs to emit a light signal which is recieved by the solar cells, converted into an electrical signal on the battery-free wireless handset and sent to the speaker.

REGENEDYNE Wind Turbine

www.Regenedyne.com Demo CGI for proposed 2GW Magnetic Leviatated wind Turbine. *Efficient Frictionless Power Generation with less maintenance, compared to HAWT. No oil change or replacement of the bearings, gears. Since, MAGLEV does NOT require such. ** Current bearing technology has forced wind turbine designers into horizontal spindle three bladed wind turbines. In this design the huge blades are connected to a spindle in the center. The bearings that support the spindle and control the pitch of the blades (which can be hundreds of feet long) see huge pitch-moment loading, some of which is manifest as torque energy that is focused through the center spindle. The target speed for the spindle is 18 or 20 rpm and the bearings holding the spindle are mounted in a huge casting which also contains a large gearbox stepping the speed up to 1800 to 2000 RPMs which allows for the proper surface speed relationship between the coils and magnets. It is necessary to invert or condition the current, which is expensive. This gearbox is full of many large bearings, gears and castings; for a 2 MW turbine the gearbox can easily weigh 30 tons. This gearbox needs to be mounted on the top of a pole more than 150 feet in the air and be able to support the turbine blades under full-force wind conditions. ***MAGLEV Power Generation, the pitch moment ratio is closer to 1-to-1 then the 100-to-1 as with a horizontal spindle design.

Kit for sale now- www.berezintechnologies.com Visit Blog at http for details on wind and other stuff I do. Part 2 is now done and covers power generation: www.youtube.com Harness the wind for less than 0. DIY vertical wind turbine of the Savonius style. Notable is that this cost less than 0 in materials so far and that the largest part of this turbine is recycled materials (the PVC drums previously held Balsamic Vinegar from Italy). Also, this turns well in a very light wind. Axle: 3 inch PVC piping from Home Depot Bearings: 5 inch lazy suzan from Lowes. Part 2 will cover power generation and connection to the battery bank.
