This paper addresses the role of power from space for use on earth in the next century. It synopsizes the problems associated with our present practices of supplying power for the world in the face of a projected increase in demand and notes the need to reduce the use of fossil fuels. The probable shortfall by the middle of the next century is estimated and options for earth-based and space-based sources of energy are examined. The paper concludes that energy obtained from space by solar power satellite is a viable and necessary way of meeting ....etc

To connect the metallic (conductive) Parts of an Electric appliance or installations to the earth (ground) is called Earthing or Grounding.

In other words, to connect the metallic parts of electric machinery and devices to the earth plate or earth electrode (which is buried in the moisture earth) through a thick conductor wire (which has very low resistance) for safety purpose is known as Earthing or grounding.

To earth or earthing rather, means to connect the part of electrical apparatus such as metallic covering of metals, earth terminal of ....etc

Space Age Technology Comes to Earth



Activity Procedures

Review with students the segment about precision agriculture and global positioning they watched previously in the video/DVD Connecting to Agriculture. How does this technology help farmers and ranchers? How does the technology affect the price of food and clothing? Does GIS/GPS help the environment? Try out the following GPS/GIS activity with your students.
Activity: Range Rambler GIS, Software Simulation

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted through space rather than being guided through an optical cable. These beams of li ....etc
