Creating Fuel From Thin Air With Artificial Leaves(结束)

用人造叶片凭空创造燃料（结束）

前景一片乐观

Bringing together all the technology into one bundle is a problem.

把所有技术整合起来就是一个问题。

"There's been some incredible science in terms of light harvesting, in terms of the catalysis that makes the fuel and in terms of managing systems," she says.

“现在在光线收集方面已经有了一些不可思议的科学研究，在制作燃料的催化剂方面和管理系统方面也有很多的研究”，她说。

"But the integration of these inpidual components into a system capable of artificial photosynthesis is a huge challenge."

“但是要把这些各自独立的部分整合到一个能进行人工光合作用的系统中，仍然是一个巨大的挑战”

It's also difficult to ensure that the reactions produce a commercially-viable fuel, with many of the catalysts that can achieve this being too expensive or too inefficient for large-scale use.

目前仍然难以确保反应生成可商用化的燃料（默然说话：就是难以量产，生成的燃料太少太贵了），因为很多催化剂要么太贵了，要么就是效率太低，无法大规模使用。

Finally, says Prof Dempsey, durability is a problem: "When you're dealing with constant radiation [sunlight] that can cause a reaction that can be highly detrimental and corrosive."

最后，邓普西教授总结道，耐用性也是一个问题：“当你持续辐射（阳光），会导致反应会有很高的危害性与腐蚀。”

As a result, artificial photosynthesis still can't produce liquid fuel cheaaply enough to compete with fossil fuels.

因此，人工光合作用仍然不能生成价格足够便宜的液体燃料，与化石燃料竞争。

"But the dynamic can change very quickly," says Prof Reisner.

“不过情况会很快发生改变”，瑞斯纳教授说。

"The oil price can change , taxation can change. And when things start shifting, at some point in the future the price of artificial photosynthesis will go down and the price of fossil fuels will go up. The question is just when these lines cross."

“石油价格会变，税收会变。一旦情况开始转好，在未来，人工光合作用的价格会下降，而化石燃料的价格会上涨，问题只是什么时候这两条线什么时候交叉。”

"If you go back 10 years, even the most optimistic predictions for the cost of photovoltaic-derived electricity did not match what happened. The cost came down by 85%, which is incredible. Once economy of scale comes in, a lot is possible. So I'm very optiimistic."

“如果你回到10年前，人们对人工太阳能发电成本，即使是最乐观的预测，也与现实情况不一样。现在成本已经下降了85%以上，很不可思议。一旦规模经济加入，一切即有可能。所以我是非常乐观的。”
