一家荷兰公司即将推出全球首个完全由太阳能电池板建立的自行车专用道。专用车道大约230英尺长-你可以在几秒钟内的蹬踏穿越它。

车道刚开始时似乎很整洁。但也存在一个良性的争议,就是这是一个非常低效的方式来产生太阳能
It seems pretty neat at first. But there's also agood argument that this is a really inefficient way to generate solar power:

自行车道,是厂商SolaRoad所建,主体由数行硅晶体太阳能电池构成,以混凝土外框包裹并覆盖以一层透光的强化玻璃层 。其将于1112日向公众开放。
The bike path, built by SolaRoad, "is made up of rows of crystal line silicon solar cells, encased with in concrete and covered with a translucent layer of tempered glass." It will open to the public on November 12.

但是,这是不是实用呢?此自行车道花费大约为370万,到2016年当它完全建成了330英尺长,将产生足够的电力供给......三户而已。不是很划算。(这是比屋顶太阳能发电在美国的价格更昂贵1000倍以上。)
But is this even practical? The bike path will cost roughly $3.7 million and, when it's fully built out to 330 feet in 2016, will generate enough electricity to power… three house holds. Not very cost-effective. (That's more than 1,000 times costlier than the price of rooftop solar electricity in the United States.)

当然,对太阳能车道的一个大的期望-就像在爱达荷州正在测试的太阳大道-一样,是他们也许能量化并在未来提供大量的电力。毕竟,我们有一切开放空间的道路和自行车道。为什么不好好的应用它?
Of course, one big hope for solar bike paths — much like with the Solar Road ways project being tested in Idaho — is that they mightbe able to scale up and provide a lot of electricity in the future. After all,we have all this open space on our roads and bike paths. Why not put it to use?

不幸的是,有一些大的缺点在这里。其一,太阳能电池板位于道路和自行车道下方会被尘土、泥沙和冰雪所覆盖,降低其效益性。厂商希望通过稍微将太阳能板做成斜面,并赋予他们一层不粘涂层,因此可藉雨水冲刷污垢脱离解决这一问题。这还有待观察效果如何。
Unfortunately, there are some big drawbacks here. For one, solar panels sitting underneath roads and bike paths can get covered in dirt and mud and ice and snow, reducing their effectiveness. SolaRoad is hoping to address this by tilting the panels slightly and giving them a non-adhesive coating, so that the rain washes the dirt off. It remains to beseen how effective this is.

另一个大问题是,这些(道路-太阳能自行车道)能板不能倾斜面向太阳,但屋顶光伏板可顺应此法。据卫报,这意味着道路-自行车道太阳能板估计将比传统面板产生降低30%的电力。
Another big problem is that these panels aren't tilted toward the sun, the way rooftop photovoltaic panels are. According to The Guardian, that means they're expected to produce 30 percent less electricity than conventional panels.

在国际可再生能源杂志上,克雷格•莫里斯认为,一旦你把诸多因素如,阴影、冬季的结冰,与为防止骑行者车滑倒的粗糙表面等项,那些能板的表现可能会更糟糕的多。 他不喜欢这整个主意:他说“在这里我希望关于这些糟糕想法的消息迅速传开,因而使该计划不致在其他地方复制。
Over at Renewables International, Craig Morris argues that the panels will probably perform much, much worse than that once you factor in shading, ice in the winter, and the rough surface needed to prevent bicyclists from slipping. He's sour on the whole idea: "Here's hoping news about how terrible the idea is gets around fast so that the projectis not copied elsewhere."

事实上,如果你真的想要一个以太阳能为动力的自行车道,莫里斯强调,会有一个更容易的选择。你可以在部分自行车道的上面安装屋顶,然后在屋顶上安装太阳能电池板。更少的污垢。可以调整面板的角度。更多的电力却少争议。(加上它会屏蔽骑自行车的人常淋到雨,纵然在阳光明媚的日子会减少一些乐趣。)
Indeed, if you really wanted a solar-powered bike path, Morris notes, there might be an easier alternative. You could install roofs above parts of the bike paths and then install solar panels on the roofs.Less dirt. You can angle the panels. More electricity with less hassle. (Plus it would shield cyclists from the frequent rain, although it would be less pleasant on sunny days.)

那就是说,即使太阳能道路和自行车道不可能产生大量的电力供家庭使用,他们至少还是具有许多潜藏的用途。这就是为什么这些技术一直还是值得测试的原因。
That said, even if solar roads and bike paths are unlikely to generate a ton of electricity for household consumption, they might have more modest uses. Which is why the technology may still be worth testing.

TreeHugger网上,劳埃德阿尔特 点出 1家荷兰公司对太阳能道路的远景:“用传感器搜集交通流量信息,可以帮助改善交通管理,甚至可以让车辆自动引导、其他可能的功能是可变换的道路标记、伴随LED灯的符号,以及冬天道路的加热。最终,用作无线能量的系统。“
Over at TreeHugger, Lloyd Alter points to one Dutch company's vision for solar roads: "Sensors gathering information about traffic circulation can help improve traffic management, or even allow automatic vehicle guidance. Other possible functions are variable road markings, ‘tag-along' LED-lights and heating in winter. And eventually, a system for wireless energy."

这可能是不像太阳能道路可能实现能够有充足的动力共电动汽车荏苒上下高速公路。但对更小的传感器或道路除冰系统而言?那并不是十分不着边际的事情。
It may be unlikely that solar roads will ever be practical enough to power electric cars zipping up and down the highway. But smaller sensors or road de-icing systems? That's not quite as far-fetched.

主要是实验太阳能,利用自行车道的空间,也可谓一举两得。和自行车与骑行者的关系在自行车道,和实验者的关系主要在于实验太阳能,文中说:
