  Wind power has the potential to provide affordable electrical power to anyone anywhere.Current systems require significant breakthrough to address performance, cost, and environmental issues.The purpose of this article is to review state-of-the-art technologies and present a discussion on which technology is more suited to bring wind power to its optimum benefits.A brief review of the wind power generation market, the basics of wind power generation, the technological advances,and summary and conclusions are presented.Wind power generation is controlled by two major factors: free stream wind speed and blade radius.These two design parameters have caused the tower height and blade sizes to be massive.In terms of manufacturing, logistics, installation, and maintenance challenges and costs, the height of the towers and size of the blades have reached their limits.Initially, wind energy was used to induce a function, such as moving boats using sail, cooling houses by circulating outside air, running machinery in farms, and even small production facilities.In late 1800s and early 1900s, conversion of wind energy to electrical power marked a turning point for the wind power generation industry.Due to energy crisis and changes in the political and social climates, wind turbines started to rapidly spread across the globe in the last 30 years.However, wind power is far from its full potential.Although manufacturers have incrementally improved conventional wind turbines, the cost of wind-generated power continues to exceed the cost of power generated by hydropower plants, coal and natural gas.Turbines are often subjected to excessive downtime, failure and repair costs are high.Moreover, complaints of harm to wildlife and human health continue to plague the industry.A recently developed technology, INVELOX solves all the major issues mentioned above giving it the potential to provide electrical power to anyone anywhere around the globe.

家住福建龙海市的74岁老人李春雷,被“尿多多”困扰了好几年。白天有事情做,感觉还不太严重,到了夜间躺在床上,尿意就频频而来,每晚都要起床两三次。起夜次数多了,睡眠自然不好,早上锻炼后回家,非要再躺一会儿。问问一起晨练的其他老人,大都有和李大爷类似的尿频现象。  正常成人日间平均排尿4~6次,夜间就寝后0~2次,每次尿量300~500毫升。如在单位时间内排尿次数明显超过正常范围,则称为尿频。尿频常“
