关于未来，人类最需要了解的10件事
<p>人类对未来世界总是充满好奇和想象。100年后我们靠什么发电？癌症会治愈吗？精神病能成为历史吗？汽车可以飞吗？近日，英国广播公司《地平线》节目的科学家团队总结了关于未来我们最需要知道的10件事情，一起来看看吧。</p><p>如何让电灯一直亮下去？</p><p><span word="Much">Much</span> <span word="of">of</span> <span word="our">our</span> <span word="electricity">electricity</span> <span word="is">is</span> <span word="generated">generated</span> <span word="by">by</span> <span word="burning">burning</span> <span word="coal">coal</span> <span word="or">or</span> <span word="gas">gas</span>, <span word="both">both</span> <span word="of">of</span> <span word="which">which</span> <span word="will">will</span> <span word="ultimately">ultimately</span> <span word="run">run</span> <span word="out">out</span>. <span word="Renewable">Renewable</span> <span word="energy">energy</span> <span word="sources">sources</span> <span word="are">are</span> <span word="fraught">fraught</span> <span word="with">with</span> <span word="their">their</span> <span word="own">own</span> <span word="problems">problems</span> (<span word="not">not</span> <span word="least">least</span> <span word="the">the</span> <span word="changeable">changeable</span> <span word="nature">nature</span> <span word="of">of</span> <span word="British">British</span> <span word="weather">weather</span>), <span word="so">so</span> <span word="could">could</span> <span word="a">a</span> <span word="Norwegian">Norwegian</span> <span word="concept">concept</span> <span word="of">of</span> <span word="erecting">erecting</span> <span word="wind">wind</span> <span word="turbines">turbines</span> <span word="thousands">thousands</span> <span word="of">of</span> <span word="feet">feet</span> <span word="in">in</span> <span word="the">the</span> <span word="air">air</span> <span word="where">where</span> <span word="there">there</span> <span word="is">is</span> <span word="always">always</span> <span word="a">a</span> <span word="breeze">breeze</span> <span word="become">become</span> <span word="a">a</span> <span word="reality">reality</span>?</p><p>大部分的电能是通过燃烧煤或天然气产生的，这两种能源最终都会耗尽。可再生能源自身存在问题（尤其对于英国多变的天气来说），那么，挪威风口处竖立数千英尺高的风力发电机的概念也许会成为现实？</p>
