Water Weco

 

Water Weco (Waterwheel+Ecoloby+Economy) is a trademark for ultra-low power generation systems developed by Ellis Co. The company offers systems with outputs ranging from a few watts to 20 kW. In addition to being a hydroelectric power generation system with extremely low environmental impact, its iutput is a much smaller range than the conventional small hydroelectric power generation range of 1,000-10,000 kW, with a water flow drop of only 1-3 meters and a flow rate of 1 m³/sec. In a place where water resources are abundantly available, it would be a waste to throw away the energy of the water flow without using it. There are so many possible locations for installation, such as discharge water from hydropower plants, industrial water, and agricultural waterways, and it is an environmentally friendly, sustainable, and decentralized energy source. It would be highly expected for the future development and spread of this system around the world. (AS)

Chalenagy Inc.

 

 　The "Vertical Magnus Wind Turbine" was developed by Mr. Shimizu, the founder of Chalenagy (hereinafter referred to as "Chalenagy"), after the devastation caused by the Great East Japan Earthquake in 2011. 　Due to its structure, it can generate electricity even with winds of up to 40m/sec, regardless of the direction of the wind, It is also less likely to be struck by birds, less likely to make wind noise, more resistant to lightning, and more suitable as an emergency power source or as a distributed power generation system.

  The company is said to be the first in the world to put magnus power generation to practical use in a vertical shaft type machine. After 10 years of development, the small machine with a rated output of 10 kW has entered the practical application stage and is currently in operation in the Philippines and on Ishigaki Island.　 

  
The company reportedly plans to mass-produce this small machine and to develop a larger generator for the future. With the expansion of renewable energy sources being called for, we can expect great things from this company in the future. (AS)
