That's because the prototype gadget, which works with an antenna and other components, made with nanoparticles of silver and other materials on an inkjet printer, can draw energy out of thin air.

这种雏形设备由纳米银颗粒和用在喷墨打印机上的其它材料制成，并与天线和其它组件配合使用，可以从稀薄的空气中获取能量。

In addition, the Earth's ionosphere (thin yellow line) and the stars of our galaxy can be made out in the fascinating footage.

此外，人们也可以在这迷人的影片中辨认出地球电离层(薄薄的黄色的线)和银河中的星星。

Melosh's group figured out that by coating a piece of semiconducting material with a thin layer of the metal cesium, it made the material able to use both light and heat to generate electricity.

Melosh的研究小组发现用薄层的金属铯覆盖在一片半导体材料上，能够使材料同时利用光和热能来产生电力。

These turned out to be thin-film photovoltaic cells, of the sort that could be sewn into a backpack and used to power a laptop.

NEWYORKER: Greening the Ghetto

Hovering close to the ground, each of these thin-shell dwellings is made entirely out of a single concrete slab stretched out to create an energy efficient structure that is environmentally greener than traditional construction methods and cheaper and faster to produce.

FORBES: Binishells: Home Of The Future

If there are fewer than 21 ratifications by the end of October 2006--and with two no votes and the U.K. and Denmark also likely to vote no, that is cutting the margin of error razor thin--the whole matter reverts to the European Council to work out, so the Council may decide to cut its losses now.
