So, while high-altitude wind may ultimately prove to be a major energy source, it requires substantial infrastructure.

因此，尽管高空风能可能最终被证明是一个主要的能源来源，它仍然需要大量的基础设施。

The aim of both teams is to tap into high-altitude wind, which is an energy source that is more abundant and reliable than the ground-level wind on which normal turbines depend.

两个研究小组的目的是一致的：利用更加丰富、稳定的高海拔风能发电，而普通的涡轮发电机则依赖于地表风能。

The system is a goldmine for scientists; the perfect laboratory for high-energy physics and a never-ending source of intriguing physical problems.

对科学家来说该系统就是座金矿：是高能物理理想的实验室以及引人入胜物理问题的源泉。

Interestingly, an April 18 paper in the journal Nature reported that upper limits for neutrinos measured from IceCube are low enough that gamma-ray bursts are unlikely to be the sole source of ultra-high energy cosmic rays.

One source of high-energy neutrinos is likely to be supernova remnants, such as the Crab Nebula.

The team of Professor Keon Jae Lee from the Department of Materials Science and Engineering, KAIST has developed a high performance flexible all-solid-state battery, an essential energy source for flexible displays (see paper in Nano Letters: "Bendable Inorganic Thin-Film Battery for Fully Flexible Electronic Systems").
