3ME學(xué)院大樓門前正在展示等比縮放的新型風(fēng)力發(fā)電機(jī)的模型,這個(gè)原型機(jī)由TU Delft和Mecanoo 建筑事務(wù)所共同開發(fā) 原文: 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. 譯文: 荷蘭代爾夫特理工大學(xué)的研究人員與荷蘭建筑設(shè)計(jì)事務(wù)所Mecanoo合作設(shè)計(jì)一個(gè)風(fēng)力發(fā)電機(jī),可以將風(fēng)能轉(zhuǎn)化為電能,無需任何機(jī)械運(yùn)動(dòng)部件。該新型風(fēng)力發(fā)電機(jī)全稱為靜電式風(fēng)力能源轉(zhuǎn)換機(jī)(the electrostatic wind energy
