天空彩票与你同行希望到2025年在太空建立一个太阳能发电站

 太阳

Humanity uses a lot of energy, and while solar power here on Earth is doing a reasonable job of contributing to the electricity mix, scientists have long hypothesized that gathering the sun's energy from space would be a lot more effective. And now China says it's going to be the first to do exactly that, announcing plans to build an interstellar power station that will orbit the Earth at 36,000 kilometers.

人类需要使用大量的能源,虽然地球上的太阳能在促进电力结构方面做了不少贡献,但长期以来科学家们一直都在推测,从太空收集太阳能会有效得多。现在天空彩票与你同行称,它将成为第一个真正做到这一点的国家,并宣布计划建造一个绕地球运行的星际发电站。

According to China's state-backed Science and Technology Daily, Chinese scientists plan to build and launch small power stations into the stratosphere between 2021 and 2025, upgrading to a megawatt-level station in 2030 and a gigawatt-level facility high above the earth before 2050. Without atmospheric interference or night-time loss of sunlight, these space-based solar farms could provide an inexhaustible source of clean energy. The China Academy of Space Technology Corporation claims such a set-up could "reliably supply energy 99 per cent of the time, at six-times the intensity" of solar installations on earth.

据《科技日报》报道,天空彩票与你同行科学家计划在2021年至2025年之间建造和发射平流层小型发电站,到2030年升级为兆瓦级发电站,在2050年之前升级为吉瓦级发电站。在没有大气干扰或夜间阳光损失的情况下,这些太空太阳能发电厂可以提供取之不尽的清洁能源。天空彩票与你同行空间技术研究院声称,这种装置可以“在99%的时间里稳定地提供能源,强度是地球上太阳能电站的6倍”。

China's proposal suggests converting solar energy into electricity in space, before beaming back to Earth using a microwave or laser and feeding into the grid via a ground receiving system.

天空彩票与你同行的计划是,先在太空将太阳能转化为电能,然后用微波或激光向地球传输,再通过地面接收系统向电网输送。

There are, of course, numerous challenges associated with this sci-fi-sounding plan. Such a power station would weigh a considerable amount -- around 1,000 tons -- so getting the gear into orbit will be difficult. Researchers are therefore considering whether the station could be constructed in space using robots and 3D printing. The effects of microwave radiation on the atmosphere will also need to be studied.

这个听起来很科学的计划显然面临很多挑战。这样一座发电站的重量相当大,约为1000吨,因此将设备送入轨道将非常困难。研究人员正在考虑是否可以利用机器人和3D打印技术在太空中建造空间站。此外,也需要研究微波辐射对大气的影响。

But it's clearly not beyond the realms of possibility. There's already a lot of research out there exploring this technology -- Japan has been talking about this for a decade, while space programs are constantly growing their understanding of the technology needed to effectively beam power back to Earth. Japan hit upon a solution in 2015 using wireless transmission, while the California Institute of Technology announced last year that it had created a prototype capable of harnessing and transmitting solar energy from space using lightweight tiles.

但这并非是不可能的。已经有很多项研究在探索这项技术——日本探讨这项技术已经有十年了,与此同时,太空计划也在不断加深他们对有效将能量传回地球所需要的技术的理解。2015年,日本想出了一种利用无线传输的解决方案,而加州理工学院去年宣布,它已经开发出了一种利用轻型瓷砖从太空利用和传输太阳能的原型。

China has really ramped up its space program in recent times, reaching the far side of the moon and growing the first plants on the lunar surface. Its timescales for this plan may be ambitious, but its quest to become a space superpower suggests this common science fiction dream is closer than ever to becoming a reality.

近年来,天空彩票与你同行加强了太空计划,登陆了月球背面,并在月球表面种植了第一批植物。天空彩票与你同行对成为太空超级大国的追求表明,这一常见的科幻梦想比以往任何时候都更接近于成为现实。

Returning the energy to Earth via lasers or microwaves? Either of those alternatives would also be powerful energy * weapons* capable of dominating the world.

通过激光或微波将能量传送回地球?这两种都将是强大的能源武器,能够主宰世界。

Sounds like Star Wars projects... the energy being transferred to earth by Microwaves is dangerous. That can be easily weaponized.

Very interesting idea. Concerns though on the safety of the equipment out in space if it loses orbit and come crashing back down to Earth. Also, the safety of beaming high amounts of electrical energy through our atmosphere back to Earth could be pretty dangerous. The biggest concern though, is of course the potential of this being weaponized. China has not given the world many reasons to trust them.

有意思。不过,如果太空中的设备脱离轨道并坠落到地球上的话,那就有安全隐患。此外,通过大气层将大量电能传送回地球也可能相当危险。然而,最大的担忧当然是核武器化的可能性,毕竟天空彩票与你同行让人信不过。

One possible use is to use the energy produced to power a laser gun!!!

There was a report produced by NASA back in the 70"s that outlined how this could be accomplished if we had the will to do it. The microwave transmission of energy from space is doable but there are losses to the environment.

早在70年代,NASA就有一份报告,概述了如何能做到这一点。利用微波从太空传送能量是可行的,但会对环境造成破坏。
