The plane uses a piston engine rather than a large-scale turbine jets, allowing it to travel unaffected through the ash, unlike large commercial jets.

该飞机使用活塞式发动机，而不是身材庞大的喷气涡轮机，因此它不会像大型商业飞机那样受到火山灰的负面影响。

The tremendous dynamic loads put on large wind turbine blades shortens the life of fiberglass blades, adding to the total cost of large-scale wind energy development.

风机运转时，风机叶片承受了巨大的动态载荷，使得玻璃纤维材料制成的叶片寿命缩短，这大大增加大型风能开发项目的总成本。

It, too, for example, is developing a floating wind turbine. It plans to install the first full-scale test model towards the end of this year.

比如说，该公司也在开发一个浮动式风力涡轮机，并计划在2009年末安装首个全规模的试验模式。

The project, part-funded by the UK's Department for Business, Innovation and Skills, saw a full-scale 44m prototype turbine blade fitted at a wind farm in Norfolk.

BBC: 'Stealth' wind turbine deployed

This will be the first commercial wind farm in the U.S. to deploy, at scale, turbines that use permanent magnet generators tech-speak for evolutionary turbine technology that will improve efficiency, reliability and grid connection capabilities.

This could be possible as there is tremendous potential for economies of scale, both in terms of mass production, which reduces the cost of each turbine, and in terms of the construction and management of vast wind farms offshore where there are few limits on available acreages.
