Tidal Power Generation

Nova Energy, an entrepreneurial company based in Hyogo Japan, developed tidal power generation systems and started its trial testing off the coast of Awaji City in the first half of the year 2010. The key component of the system is a tuna shaped turbine "MAGURO TURBINE", of which type number NT-001 has a 6-meter-long body with a 3 meter-diameter of propeller, is designed to generate 10kw at 3 knot tide current speed.　Maguro Turbine is not actually for generating electric power but to generate oil pressure power which is transformed to rotate oil turbines for electric power generation. 　For a country surrounded by the sea, like Japan, there could be huge potential to use the sea power of clean energy. We do hope the trial will be successfully completed together with a reasonable cost performance result.

Spiral Magnus - a wind power generator

About one year ago, February 2008, I introduced at this blog site Spiral Magnus wind generator designed and manufactured by MECARO . It seems that the new generator is now in commercial production. The first commercial unit reportedly installed in Ogata Village, Akita Prefecture, Japan last November. This video is a brief presentation on the product. According to the supplier, MECARO , the strong advantage of Spiral Magnus are in low speed rotation, exceptionally quiet operation, long lasting durability as well as high efficiency and stability in power generation that have been enabled by Spiral Effect together with MECARO's patent technology. Typical specifications data extracted from the supplier's web site are as follows. Wind Turbine Diameter: 11.5m Rated Output: 12kW Rated Wind Speed: 11m/s Rated Rotor Speed: 30rpm Cut-in Wind Speed: 3m/s Cut-out Wind Speed: 30m/s Wind Load Survival Rate: 60m/s Source: MECARO's promotion video via Y

Radiation-Watch - Excellent Project Where Good Ideas Have Got Together

Radiation-Watch.org , an open and non-profit project formed up in Japan, took an excellent approach to develop and launched very inexpensive and smart radiation detectors to the international market. The organization is supported by a variety of people, such as scientists, engineers and designers on a global basis. The organization surprisingly enough to have designed, developed manufactured, and launched the first model, Pocket Geiger Type 1 within just three month soon after the team made its decision to get the thing done. All of the team members shared their own expertise on purely good will basis using their off-times, weekends and nights in weekdays. Needless to say, scientific, technological and engineering expertise the team members hold are the first class while there were three key factors for the successful fast launch of the high quality radiation detector. Firstly, they used Kickstarter to get financial support for the project. Using the system, Radiation-watch

Wireless High-definition Quality Video Transmission Units

This system that consists of a receiver (left) and a transmitter wirelessly enables HD (30 frames/sec) quality video and stereo sounds transmission but with no compression and no delay time. The supplier, Giga Techno Vision's blog says the system is well secured because of its proprietary and patented technologies that differ its digital modulation method from wireless LAN. - Frequency Area 2.4GHz - Transmission power: 10 mW - Radio Channel Capacity 4ch Maximum - Diversity Method: Space-diversity 2 antennas - Size (Tx & Rx each): 110(W) x 80(Ｄ) x 30(Ｈ)mm - Weight (Tx & Rx each): approximately 300g - Transmission distance: 500 m outdoors (up to 3 km) There seem to be various applications, such as remote monitoring, CCTV, home video theater application, surveillance systems, etc. I hope in the near future the system become one single chip for receiver and transmitter each. When the chip becomes available, it will significantly broaden its applications to personal and
