Researchers at TU Delft have teamed up with Dutch architecture firm Mecanoo to design a wind turbine that can transform wind energy into electricity without any mechanical moving parts. The turbine, dubbed the EWICON, was installed at the Delft University of Technology in March.

The Electrostatic Windenergy Convertor (EWICON) is a wind turbine that has no moving parts. Designed by Mecanoo, the prototype uses the technology developed by the EWI faculty in collaboration with Wageningen University and several companies involved in a government ecology project. The bladeless wind turbine uses the movement of electrically charged water droplets to generate power. It can be installed both onshore and offshore, or mounted on a roof.

The EWICON’s steel fram supports a framework of horizontal steel tubes. Within the framework, electrically charged droplets are created and blown away by the wind. Their movement creates an electric current that is then passed on to the grid. The remarkable wind turbine produces zero noise pollution; it doesn’t cast shadows, and because there are no moving parts, it has much lower maintenance costs than conventional wind turbines.

荷兰代尔夫特理工大学的研究人员与荷兰建筑设计事务所Mecanoo合作设计一个风力发电机，可以将风能转化为电能，无需任何机械运动部件。该新型风力发电机全称为静电式风力能源转换机（the electrostatic wind energy converter，简称EWICON），为钢框架结构，中间为导电矩阵。该技术由荷兰代尔夫特理工大学化学与航空工程系，以及荷兰瓦格宁根大学（wageningen university）合作开发，被认为是下一代风力能源应用技术的发展方向。

新型风力发电原理：

原理可以解释的很简单，风吹动电子，导致电子的流动从而产生电。理论上，在正负两级之间，正离子会由于力的作用自动向负极移动。而静电式风力能源转换机则可借助风的力量，让携带正点的静态水分子向正极移动从而形成环形电流。该能量可以通过一定的方法采集并转换后用于日常电力供应。通过电子流的移动来代替传统技术上机械移动，可以大为提高风力发电的使用简便性和操作性。

（在Mecanoo architects网站上的介绍里，有该新型风力发电转换机的原理介绍视频；此视频也可在优酷上找到，本博已随文。）。它可以安装在陆地和海上，或安装在屋顶。

EWICON的钢框架支持的水平钢管框架。框架内，带电的液滴，被风带走。他们的运动产生电流，然后被传递到电网。卓越的风力发电机产生的噪音污染为零，因为有没有可移动部件，它比传统风力发电机具有更低的维护成本。
