So let's project this analogy going forward. We think about energy scarcity.
让我们把这个比喻应用到其他方面，让我们想一想能源短缺。
Ladies and gentlemen, we are on a planet that is bathed with 5,000 times more energy than we use in a year.
女士们先生们，我们生活的这个星球上接收着相当于我们年平均能源消耗5000多倍的能量。
16 terawatts of energy hits the Earth's surface every 88 minutes. It's not about being scarce, it's about accessibility.
每88分钟有16太瓦的能源投向地球表面。问题并不是能源稀缺，而是可及性。
And there's good news here. For the first time, this year the cost of solar-generated electricity is 50 percent that of diesel-generated electricity in India -- 8.8 rupees versus 17 rupees.
现在有几个好消息，今年是有史以来第一次在印度，太阳能发电的成本降低至化石燃料发电成本的一半--8.8卢布相比较17卢布。
The cost of solar dropped 50 percent last year. Last month, MIT put out a study showing that by the end of this decade,
去年太阳能发电的成本降低了一半，上个月，MIT发布了一个研究报告，显示到2020年，
in the sunny parts of the United States, solar electricity will be six cents a kilowatt hour compared to 15 cents as a national average.
在美国阳光充足的地区，太阳能电力费用会降至6美分一千瓦／小时，相比较全国平均标准是15美分。
And if we have abundant energy, we also have abundant water. Now we talk about water wars.
如果我们有充足的能源，也就会有丰富的洁净水。下面我们来聊下水的战争。
Do you remember when Carl Sagan turned the Voyager spacecraft back towards the Earth, in 1990 after it just passed Saturn?
还记得吗？1990年，Carl Saga在航海者太空飞船经过土星的时候，调转其方向面对地球。
He took a famous photo. What was it called? "A Pale Blue Dot." Because we live on a water planet. We live on a planet 70 percent covered by water.
拍下了一幅著名的照片，叫什么名字？“淡蓝色的小点”。因为我们生活在一颗“水行星”上，地球表面70％被水覆盖。
Yes, 97.5 percent is saltwater, two percent is ice, and we fight over a half a percent of the water on this planet, but here too there is hope.
是的，97.5％是海水，2%是冰山，我们则在争夺世界上1.5%的水资源，但我们仍然有希望。
And there is technology coming online, not 10, 20 years from now, right now. There's nanotechnology coming on, nanomaterials.
有一项科技正准备投入应用，并不是未来的10年20年以后，就是现在。有一种纳米科技。
And the conversation I had with Dean Kamen this morning, one of the great DIY innovators, I'd like to share with you -- he gave me permission to do so --
今天早上我和一个伟大的DIY发明家Dean Kamen聊天。我想要和大家分享－我得到了他的允许－
his technology called Slingshot that many of you may have heard of, it is the size of a small dorm room refrigerator.
他开发的技术叫做“弹弓”，在座的一些朋友可能听说过，它是一个小房间一般大的冰箱，
It's able to generate a thousand liters of clean drinking water a day out of any source -- saltwater, polluted water, latrine -- at less than two cents a liter.
每天可以从任何水源中－海水，污染水，公共厕所－生产出一千公升的洁净饮用水。每公升的成本低于2美分。
The chairman of Coca-Cola has just agreed to do a major test of hundreds of units of this in the developing world.
可口可乐的主席最近授意，在多个发展中国家对数百台“弹弓”进行大规模测试。
And if that pans out, which I have every confidence it will, Coca-Cola will deploy this globally to 206 countries around the planet.
如果测试成功，我很有信心它会成功，可口可乐将会在全球206个国家对该设备进行部署。
This is the kind of innovation, empowered by this technology, that exists today.
这就是当下已经存在的由科技驱动的创新。
