Wireless Power Transmission for Solar Power Satellite (SPS) (Second Draft by N. Shinohara) 1. Theoretical Background It is known that electromagnetic energy also associated with the propagation of the electromagnetic waves. We can use theoretically all electromagnetic waves for a wireless power transmission (WPT). The difference between the WPT and communication systems is only efficiency. The Maxwell’s Equations indicate that the electromagnetic field and its power diffuse to all directions. Although

TEZOL 3 October 2013 NEEDS TO SURVIVE IN A JUNGLE Almost 300 cases of disappearances in the jungles of South America were recorded in 2012‚ and more than half of the people are still not found today. Getting lost in a jungle is not a rare occasion! Due to tree canopies darkness falls quickly in a jungle‚ which might cause you to find yourself in the midst of jungle in pitch dark. Therefore you have to be aware of the dangers and know how to protect yourself. To survive in a jungle‚ you need to know

This paper is about how the plant cells and solar cells are similar to each other as well as how they are different to one another. In addition this paper explains how the laws of thermodynamics apply to each of the plant and solar cells system. Plant Cells and Solar Cells Photosynthesis is the process of producing and releasing oxygen in the air. It needs sunlight‚ carbon dioxide and

Space-based solar power (SBSP) is the concept of collecting solar power in space for use on Earth. It has been in research since the early 1970s. SSPS consists of a space-based power generation/transmission facility that gathers sunlight‚ converts it into microwaves or laser beams‚ and transmits those to the ground; and a power receiving facility on the ground. Space-based solar power essentially consists of three elements: • a means of collecting solar power in space‚ for example via solar cells or

Neither the life of an individual nor the history of a society can be understood without being able to understand both. Discuss. To make true the desires of the ancient philosopher Socrates we now live in a world that dares us to think for ourselves. We are now in a position to shape our own destinies more so than ever before due to the greater social mobility which we now have at our disposal. As a whole the world has gone from agrarian to a much more capitalist age in which people are never satisfied

Solar Energy Topics Solar technologies use the sun’s energy and light to provide heat‚ light‚ hot water‚ electricity‚ and even cooling‚ for homes‚ businesses‚ and industry. More basic information about solar is also available. Solar Technologies Photovoltaics (PV) Photovoltaic solar cells‚ which directly convert sunlight into electricity‚ are made of semiconducting materials. The simplest cells power watches and calculators and the like‚ while more complex systems can light houses and

The purpose for all things flow from who God is and central‚ to who God is‚ to all his purposes and to all creation‚ is triune nature. God spoke into existence the natural world. In Genesis one it informs us of how God brought every natural into existence. God forms the land and divides the waters with it.

types of radiation surrounding us. As human beings‚ we are primarily exposed to natural forms of radiation such as radon‚ cosmic (space) radiation‚ and naturally occurring radioactive elements found in the Earth. We are also exposed to man-made radiation including medical radiation. Nearly half of the radiation in which the US population is exposed to comes from medical sources such as CT scans‚ x-rays‚ and nuclear medicine. In 1899‚ Ernest Rutherford discovered that the radiation emitted by

Stars A star is a massive‚ luminous sphere of plasma held together by gravity. The nearest star to Earth is the Sun‚ which is the source of most of the energy on the planet. Solar System The Solar System consists of the Sun and its planetary system of eight planets‚ their moons‚ and other non-stellar objects. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. The vast majority of the system’s mass is in the Sun‚ with most of the remaining mass contained

if UV Radiation induced a mutation in the DNA of Serratia Marcescens and prevented the production of the red pigment called Prodigiosin. Hypothesis: Maybe the disappearance of red color in Serratia Marcescens is caused by the UV light which induces mutations in its DNA and is known as a common mutagen. Prediction: If UV light mutates the DNA of Serratia Marcescens then the red pigment colonies of the bacteria will no longer be produced. Independent Variable: Ultra Violet Radiation Dependent
