风筝通过拖拉系在地面发电机上的绳索发电。
A kite generates power by pulling on a string attached to generators on the ground.
在美国有23个相似的反应堆由11家不同的公司经营，这些反应堆的备用发电机普遍被安置在地面上的碉堡状的掩体之中。
In the U.S., where there are 23 similar reactors operated by 11 different companies, backup generators typically are housed in bunker-like buildings at ground level.
但是，如果此处地面确实是倾斜的，这则意味着风(贴近地面吹向叶面)从一种角度吹向发电机叶片，而非正面对吹。
But if that ground is, indeed, sloping, it means that the wind (which tends to follow the ground when it is close to the surface) hits the blades of the turbines at an Angle instead of face on.
海啸看来还冲走了位于地面之上的发电机油箱，以及重要的核电站电力开关装置。
The tsunami also apparently washed away the generators' fuel tanks, which were above ground, as well as important electrical switching equipment for the complex.
与传统的地面式发电机不同的是，这种风筝供能系统只需占用很小的土地空间。
Also, unlike a field-full of wind turbines, kite power requires a minimal amount of land use.
位于加州的Joby能源公司测试风筝发电系统，将风筝放飞到400米的高度(1300英尺)，该高度大概是地面风力发电机高度的5倍，在400米的高度风力更强蕴含更高能量。
Joby Energy in California is testing kites flying at an average height of 400m (1,300ft) - around five times the height of a ground-based turbine - where winds are faster and more consistent.
我们的飞机动力不足，现在在地面上有台发电机，我们准备借助它来发动飞机上的引擎。
We had no power on the plane. We have a generator on the ground right now, and we are going to jump-start the engines.
在美国，有11家不同的公司运营着23个类似的反应堆，备用发电机通常放置在处于地面水平的类似于防空洞的建筑中。
In the U. S., where there are 23 similar reactors operated by 11 different companies, backup generators typically are housed in bunker-like buildings at ground level.
我们的飞机动力不足，现在在地面上有台发电机，我们准备借助它来发动飞机上的引擎。
We had no power on the plane. We have a 7 generator on the ground right now, and we are going to 8 jump-start the engines.
柴油发电机组以其结构紧凑、占地面积小、热效率高、起动迅速、控制灵活等特点成为备用电源或应急电源的首选。
Diesel generating set had become the preferred backup or emergency power because of these characteristics: tight structure, small size, thermal efficiency, rapid start, flexible control.
通过在地面定子线圈中注入高次谐波电流和在列车的磁极上加绕一组直线发电机线圈，实现磁悬浮列车在低速运行时车载蓄电池的充足供电。
It is realized by adding a high frequency current to the original current of the stator and adding linear generator windings to magnetic pole.
第二个则更像一个风筝，把机械能传递到地面，然后用发电机把它转化成电能。
The second is more like a kite, transmitting mechanical energy to the ground, where generators turn it into electricity.
