SGER: Power Transmission From Space Using Radio Waves

这项探索性研究的小资助金(SGER)将利用电磁波研究电力的远距离传播。使用微波(一种特殊形式的电磁辐射)和激光从太空传输能量已经讨论了30多年。建议更新讨论情况，审查目前的能力和相关问题，举办一次有关各方的讲习班，并就这一专题编写一份报告。这份建议提出了一份可能的报告大纲，并描述了开发研究报告所遵循的过程。所有的电磁波，或无线电波，都含有电力。最常见的话题是蜂窝无线电系统中的功率传播。基站向用户的方向传输电力。当无线电波波束在距离上发散时，这种能量就会传播开来。大量的电力从地球上的一个点传输到另一个点已经被证明了。然而，微波传输电力的主要兴趣是在太空(那里一天24小时都可以获得太阳辐射)收集电力，并使用窄而可控的光束将其有效地传输到地球上的任何地方。另一种选择是以激光束的形式传输电力。最后，微波功率被转换成电力，用作市电。近十年来出现了有助于这一进程的相当大的事态发展。电力可以传输到偏远地区，用于其他太空应用，提供紧急电力，或根据需要用作充电电力。需要进行一项研究，以确定其电力传输方式目前的可行性，简要确定高功率传输对环境的影响，并简要概述经济问题。将提出实验，使这些问题能够得到进一步探讨。

This Small Grant for Exploratory Research (SGER) will investigate the propagation of power over distance using electromagnetic waves. Transmission of power from space using microwaves (a particular form of electromagnetic radiation) and lasers has been discussed for more than thirty years. It is proposed to update the discussion, review current capabilities and relevant issues, hold a workshop of interested parties, and to develop a report on the topic. This proposal presents a possible outline of the report and describes the process to be followed in developing the research report.All electromagnetic, or radio waves, contain power. The most familiar topical reference is the propagation of power in cellular radio systems. A basestation transmits power in the direction of a user. This power spreads out as the radio wave beam diverges over distance. The transmission of significant amounts of power from one point to another on earth has been demonstrated. However the main interest in microwave transmission of power is to collect power in space (where solar radiation is available 24 hours a day) and transmit it efficiently to anywhere on earth using a narrow, controlled, beam. Transmitting power as a laser beam is an alternative. Finally the microwave power is converted to power for use as mains electricity. The recent decade has seen considerable developments that would assist this process. Power could be beamed to remote locations, be used in other space-born applications, provide emergency power, or be used as top-up power as needed. A study is required to determine the current feasibility eif his means of power transmission, briefly determine the environmental impact of high power transmission, and briefly outline the economic issues. Experiments are to be proposed that will enable the issues to be explored further.
