That's enough to power a block of suburban homes. It's also equal to about 25 horsepower, which is about the power of the motor in the electric-model Smart Car.
这足够供应一整个街区的家庭用电了。19.2千瓦大致相当于25马力，差不多是Smart电动车的引擎功率。
At current electricity prices, Yoda would be worth about $2/hour.
按照目前的电价，尤达每小时发出的能量价值约为2美元。
But telekinesis is just one type of Force power. What about that lightning the Emperor used to zap Luke? The physical nature of it is never made clear, but Tesla coils that produce similar displays draw something like 10 kilowatts-which would put the Emperor roughly on par with Yoda. (Those Tesla coils typically use lots of very short pulses. If the Emperor is sustaining a continuous arc, as in an arc welder, the power could easily be in the megawatts.)
但远距施力只是原力的其中一种形式。西斯大帝用来震击卢克的闪电又如何呢？这道闪电的物理本质始终没讲明白，但能够产生相似场景的特斯拉线圈的功率在10千瓦左右，表明大帝的输出功率和尤达相当。（这些特斯拉线圈一般用的是许多持续时间很短的脉冲，如果西斯大帝能够像电焊机那样一直维持电弧的话，输出功率将轻松突破百万兆瓦。）
What about Luke? I examined the scene where he used his nascent Force powers to yank his lightsaber out of the snow. The numbers are harder to estimate here, but I went through frame-by-frame and came up with an estimate of 400 watts for his peak output. This is a fraction of Yoda's 19kW, and was sustained for only a fraction of a second.
那么卢克呢？我检验了一下他用原力把光剑从雪里拔出来的场景。具体的数字很难估算出来，但我进行了逐帧分析之后，得出的估计值是400瓦的峰值输出。这和尤达19千瓦的输出相比实在不足一提，而且持续时间也只有几分之一秒。
So Yoda sounds like our best bet as an energy source. But with world electricity consumption pushing 2 terawatts, it would take a hundred million Yodas to meet our demands. All things considered, switching to Yoda power probably isn't worth the trouble-though it would definitely be green.
所以用尤达作为能量源看起来是最好的选择。不过随着全世界用电量迫近2太瓦，我们需要1亿个尤达才能满足供电需求。总之把所有的因素考虑在内，换用尤达发电很可能是得不偿失——但这绝对是一种绿色能源。
