Solar power from space 太空太阳能 Beam it down, Scotty 老兄，传下来吧 Harvesting solar power in space, for use on Earth,comes a step closer to reality 在太空获取太阳能以供地球之用:梦想距现实又近了一步 THE idea of collecting solar energy in space and beaming it to Earth has been around for atleast 70 years. 在太空获取太阳能并传送回地球这一创意存在了至少有70年了。 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. 由艾萨克阿西莫夫创作、1941年发表的短篇故事《推理》，描述了一个太空站将获取的太阳能以微波束的方式传送至多个星球的场景。 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. 相比于让阳光穿过大气层后再获取太阳能，在太空中截取太阳能的一大优点就是大气吸收的能量很少。 By converting it to the rightfrequency first a space-based collector could, enthusiasts claim, yield on average fivetimes as much power as one located on the ground. |
