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

driving our cars? Will we strip-mine our land for coal and poison the air we breathe to drive our autos an additional 100 years? Will we raze our forests for our energy needs? I certainly hope our country will never come to those conclusions. However‚ someone must make a conclusion hopefully toward an alternate fuel source. The fuel source I would propose is biomass fuel derived from hemp. Hemp is the world’s most versatile plant. It actually improves the soil in which it grows‚ without chemical

change. Solar thermal (heat) energy is a carbon-free‚ renewable alternative to the power we generate with fossil fuels like coal and gas. This isn’t a thing of the future‚ either. Between 1984 and 1991‚ the United States built nine such plants in California’s Mojave Desert‚ and today they continue to provide a combined capacity of 354 megawatts annually‚ power used in 500‚000 Californian homes [source: Hutchinson]. Reliable power‚ at that. In 2008 when six days of peak demand buckled the power grid

renewable power sources are better than nuclear power? Nuclear power is the most productive power source. However‚ there are several ongoing debates around the efficiency and the usage of nuclear power. Several factors such as the catastrophes in Chernobyl and Fukushima and the depleting of coal and gas reserves have led to the idea behind the renewable power sources. The renewable power sources are the future of the energy production in the world. Renewable energy is the energy that comes

Wind Energy: Energy from Moving Air Abstract This paper contains the description of the process by which the wind is used to generate mechanical power or electricity‚ also describe the prospect and history of wind energy. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes‚ businesses‚ schools

The most renewable source of energy in Ireland is wind power. Ireland is a small island country situated at the very north west of Europe where the resource of wind is abundant. At 50 meters above ground level at all the 5 main points open plain‚ open sea‚ sea coast‚ hills and ridges and sheltered terrain Ireland has a significant amount of wind and wind resource which increases the potential for renewable energy generation. All this free wind could power schools and homes throughout Ireland.

contribution to human energy needs is substantial — worldwide‚ solar electricity generation is a growing‚ multibillion dollar industry. But solar’s share of the total energy market remains rather small‚ well below 1 percent of total energy consumption‚ compared with roughly 85 percent from oil‚ natural gas‚ and coal. Those fossil fuels cannot remain the dominant sources of energy forever. Whatever the precise timetable for their depletion‚ oil and gas supplies will not keep up with growing energy demands. Coal

Sources of Power Power is very important in any organization whether it’s in the public or private sector. A person’s title or position determines the level of power they have to change policies and/or organizational structures. The ability to convince others‚ to lead others to your own conclusion‚ to use logic and facts to make people believe you are right. Power is a possessive word that possesses authority above others.
