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.

这项探索性研究（SGER）的小额资助将研究使用电磁波的电力远距离传播。利用微波（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三十多年。建议更新讨论情况，审查现有能力和相关问题，举办一次有关各方研讨会，并编写一份关于这一专题的报告。本建议提出了一个可能的报告大纲，并描述了在编写研究报告时应遵循的过程。所有电磁波或无线电波都含有能量。最熟悉的专题参考是蜂窝无线电系统中的功率传播。基站在用户的方向上发射功率。这种能量随着无线电波束在一定距离上的发散而扩散。大量的能量从地球上的一点传输到另一点已经被证明。然而，微波传输功率的主要兴趣是在太空中收集功率（太阳辐射每天24小时可用），并使用狭窄的受控光束将其有效地传输到地球上的任何地方。作为激光束传输功率是一种替代方案。最后，微波功率被转换成用作市电的功率。近十年来出现了有助于这一进程的重大事态发展。电力可以被传送到遥远的地方，用于其他太空应用，提供紧急电力，或者根据需要用作补充电力。需要进行一项研究，以确定目前输电方式的可行性，简要确定大功率输电对环境的影响，并简要概述经济问题。将提出一些实验，以便进一步探讨这些问题。
