1、www.XiYuS锡育软件Early visions of wireless power actually were thought of byNikola Tesla basically about 100 years ago.无线电力的早期设想 主要来自于尼古拉特斯拉 大约在一百年前00:11The thought that you wouldnt want to transfer electricpower wirelessly,no one ever thought of that.问题在于 你并不需要无线输送电力 甚至没有人想到过这一点00:20They thought,Who wo
2、uld use it if you didnt?他们想：“如果连做都做不出来，谁还会用呢？”00:27And so,in fact,he actually set about doing a variety ofthings.因此，他开始着手于 进行一系列探索工作00:29Built the Tesla coil.This tower was built on Long Island backat the beginning of the 1900s.建造特斯拉线圈。这座塔建立在 20世纪初的长岛上00:34And the idea was,it was supposed to be able
3、 to transferpower anywhere on earth.此项设想在于，它将能够把电力 输送到世界上任何一个角落00:40Well never know if this stuff worked.Actually I think theFederal Bureau of Investigation took it down for securitypurposes,sometime in the early 1900s.我们也许永远不会知道这能否成功。事实上我认为依据联邦调查局的调查结果 这个项目基于安全原因被关闭了 这还是在20世纪早期的某些时候00:44But the one
4、 thing that did come out of electricity is that welove this stuff so much.但是我们从中发现 我们喜欢上了这个项目（理念）00:53I mean think about how much we love this.想想到底我们有多喜欢它00:57visions:n.愿景;幻觉(vision的复数);生理眼科视力/v.想像;显现(vision的三单形式)wireless:adj.无线的;无线电的/n.无线电/vt.用无线电报与联系;用无线电报发送/vi.打无线电报;打无线电话 wirelessly:用无线电报与联系;用无线电
5、报发送(信息等):/打无线电报;打无线电话 at the beginning of:在的开始 Bureau:n.局,处;衣柜;办公桌If you just walk outside,there are trillions of dollars that havebeen invested in infrastructure around the world,putting upwires,to get power from where its created to where its used.当你走出门，会发现在世界上 有亿万美元被投资于基础设施中 铺设电缆，将电力从其被创造的场所 输送到被
6、使用的场所00:59The other thing is,we love batteries.另外一点是，我们喜欢电池01:10And for those of us that have an environmental element to usthere is something like 40 billion disposable batteries builtevery year.对于我们来说，这在环境上的影响是 每年在世界上约有 四百亿节电池被废弃01:13For power that generally speaking,is used within a fewinches or
7、a few feet of where there is very inexpensive power.一般而言，电池 仅仅是在几英寸或几英尺的范围内使用 而且使用成本极低01:21So before I sort of got here,I thought,You know,I am fromNorth America.所以在我继续演讲之前 我想：“你们知道，我来自北美。01:28We do have a little bit of a reputation in the United States.我们在美国确实有一些声誉。”01:33So I thought Id better look
8、 it up first.所以我想最好先看一看01:36So definition number six is the North American definition ofthe word suck.数字六的定义 在北美被定义为“恶心”01:38Wires suck,they really do.电缆真令人恶心，确实如此01:44Think about it.Whether thats you in that picture orsomething under your desk.想一想，在这幅照片中的是否是你 或是位于你桌下的什么东西01:46trillions:n.数万亿/adj.万亿

10、我们周围发生的一切02:00They fall apart,they disintegrate,and they end up here.它们被取下来，被拆分 最终在此得到处理02:02So when you talk about expensive power the cost perkilowatt hour to supply battery power to something is on theorder of two to three hundred pounds.当你谈论昂贵的电力时，即 为电池或者其他东西提供电力时 每千瓦小时成本 大约是二三百英镑02:06Think abou
11、t that.想一想02:18TED演讲者：Eric Giler|艾力克基勒演讲标题：Eric Giler demos wireless electricity|无线电力输送内容概要：As the CEO of MIT-inspired WiTricity,Eric Giler has a plan to beam electric powerthrough the air to wirelessly power your laptop or recharge your car.You may never plug inagain.艾力克基勒希望利用无线电力输送技术将人类从有线生活中解放出来。
12、在此他介绍了此项科学技术所能提供的服务，并展示了MIT关于此技术的突破性想法WiTricity，一种贴近于市场并可快速为您的手机，汽车以及心脏起搏器充电的新发明。The most expensive grid power in the world is thousandths ofthat.世界上最贵的电力网络 是这个的成千上万倍02:20So fortunately,one of the other definitions of suck that wasin there,it does create a vacuum.幸运地是，“恶心”的另一个定义就在其中 它制造了真空02:25And n
13、ature really does abhor a vacuum.但是，大自然憎恶真空02:31What happened back a few years ago was a group oftheoretical physicists at MIT actually came up with thisconcept of transferring power over distance.几年以前 麻省理工的某些理论物理学家们 提出了一种近距离无线传输电力的理念02:34fall apart:崩溃;土崩瓦解;破碎 disintegrate:vt.使分解;使碎裂;使崩溃;使衰变/vi.瓦解;碎

15、且他们在约两米的距离时 点亮了一盏六十瓦的电灯炮02:44They took,it got about 50 percent of the efficiency.他们计算出的能源效率大约是50%02:50By the way thats still a couple thousand times more efficientthan a battery would be,to do the same thing.事实上，这种利用能源的方式 比电池要高出成百上千倍02:53But were able to light that,and do it very successfully.并且这已经可
16、以点亮电灯泡了 并且成功地实现了02:58This was actually the experiment.So you can see the coilswere somewhat larger.这就是那个真实的实验。所以你可以看到 存在更大的线圈03:02The lightbulb was a fairly simple task,from their standpoint.从他们的角度来看电灯泡只是一个简单的任务03:07This all came from a professor waking up at night to the thirdnight in a row that hi
17、s wifes cellphone was beeping becauseit was running out of battery power.这全部来源于某位教授 在半夜时连续三次被闹醒这是因为他夫人的手机一直在提示 电量不足（低电量警告）03:10And he was thinking,With all the electricity thats out therein the walls,why couldnt some of that just come into thephone so I could get some sleep?所以他在想：“所有的插座都在墙上，为什么就不能弄点
18、电到手机里，让我睡个安稳觉？”03:20And he actually came up with this concept of resonantenergy transfer.并且他的确实现了这个想法 通过共振传输能量03:27watt:n.瓦特 at a distance:在远处;有相当距离 coils:n.电线圈(coil的复数);卷 cellphone:n.蜂窝式便携无线电话;大哥大beeping:vi.嘟嘟响/n.哔哔的声音;警笛声/vt.嘟嘟响 resonant:adj.洪亮的,共振的;共鸣的But inside a standard transformer are two coi

20、n a transformer to a greater distance than the size ofthose transformers using this technology,which is notdissimilar from the way an opera singer shatters a glass onthe other side of the room.索尔贾希克博士所想到的是 如何将变压器中线圈的距离增大 以便在更远的距离中 应用此项技术，这与歌剧歌手 在房间的另一面摇晃玻璃窗的方式不同03:45And its a resonant phenomena for
21、which he actually receiveda MacArthur Fellowship Award,which is nicknamed theGenius Award,last September,for his discovery.这是一种共振现象 据此他获得了麦克阿瑟奖 此奖项也被戏称为天才奖 基于他的发现，在去年九月他得到了这一奖励04:01So how does it work?那么它是如何工作的呢？04:11Imagine a coil.For those of you that are engineers,theres acapacitor attached to it
22、 too.想象一卷线圈，对于是工程师的你来说，它 同时还有电容与之相连04:13And if you can cause that coil to resonate,what will happenis it will pulse,at alternating current frequencies,at a fairlyhigh frequency,by the way.如果你能够让线圈发生共振 它将会在不断改变的频率下 在相当高的频率下 产生脉冲04:18transformer:n.电变压器;促使变化的人 transformers:n.电变压器(transformer的复数);促使变化的人

25、rn itinto magnetic field,take that magnetic field,turn it back intoelectricity.接下来你要做的只是在你需要电力时 移动到磁性区域内，利用磁场 将其转变成电能04:45And then you can use it.然后你就可以正常使用了04:51www.XiYuS锡育软件Number one question I get asked.我所被问到的第一个问题是04:54I mean people are worried about cellphones being safe.人们会担心手机的安全性问题04:56You
