Solar power fromspace,Beam it down, Scotty. 从太空采集太阳能,传送电力到地球吧,斯科蒂。 Harvesting solar power in space, for use on Earth, comes a step closer to reality 将太空收获的太阳电能在地球上利用，这种理想又向现实迈出了一大步。 THE idea of collecting solar energy in space and beaming it to Earth has been around for atleast 70 years. 从太空中收集太阳能并将其传送到地球的想法已经存在了至少70年。 In Reason , a short story by Isaac Asimov that was published in 1941, a space stationtransmits energy collected from the sun to various planets using microwave beams. 艾萨克阿西莫夫在1941年出版的短篇小说Reason中曾设想利用微波束将空间站收集到的太阳能传送到各类行星上。 The advantage of intercepting sunlight in space, instead of letting it find its own way throughthe atmosphere, is that so much gets absorbed by the air. 从太空直接截获太阳光而不任由它们穿过大气层的优点是大部分光能量不会被大气吸收。 By converting it to the right frequency first a space-based collector could, enthusiasts claim, yieldon average five times as much power as one located on the ground. |
