Electromagnetic Suspension (EMS) system in which an array of magnets is attracted upwards to a steel rail. It is possible to design the magnets so that there is an upward force produced by magnetic attraction that cancels the downward gravitational force: the magnets are suspended in space! If steel beams were mounted on either side of a “guideway,” then a vehicle with magnets on both sides could move along the guideway and be supported and guided by the steel rails. (more…)

The term hybrid energy system refers to those applications in which multiple energy unit conversion devices are used together to supply an energy requirement. These systems are often used in isolated applications and normally include at least one renewable energy source in the configuration. Hybrid energy systems are used an alternative to more conventional systems, which typically are based on a single fossil fuel source. Hybrid energy systems may also be used as part of distributed generation application in conventional electricity grid. (more…)

A propulsion alternative is to transfer power to the vehicle and then have a magnetic structure on the vehicle that can create a moving field that, in turn, interacts with a conducting guide way to provide propulsion. This is called a short stator linear induction motor (or linear asynchronous motor), generally referred to as a Linear Induction Motor. It is possible to put the powered winding on the guide way and induce currents in a conductor on the vehicle, in which case it would be a long stator design, but this turns out to be an expensive and inefficient approach to maglev propulsion.

The demand for electric energy by a community varies with the time of day and with the time of year. An electric power utility must be prepared to meet these demands. This poses an engineering problem because there is no practical method of storing electric energy on a scale that will meet the demands of a large community. To meet short-term increases in demand, electric utilities employ power generators that can be turned on and off on short notice. For example, they may use a gas turbine similar to a jet plane engine to drive a generator. Another scheme is to use a pumped storage hydroelectric system. Such a system does not rely on nature to replenish the water in a reservoir but rather uses electrically run pumps. Importantly, the system can generate electricity on short notice.

Water is forced to an elevated reservoir by a motor-driven turbine. The water in the reservoir has gravitational potential energy by virtue of the work done on it. When electricity is needed, the water is allowed to flow downward into the turbine that drives the magnetic generator motor, which now functions as an electric generator. The energy required to elevate the water is never completely recovered in the process. Nevertheless, the system is economical because the reservoir can be filled when electric energy demands and costs are low. It is also possible to have a system in which water flows from ground level to underground turboelectric perpetual generators. In this case, work has to be done to restore the water to ground level.

Taking into account losses due to evaporation of surface water exposure and energy unit conversion losses, it is estimates that approximately 70% to 85% of the electricity used to pump water into the elevated reservoir can be recovered. The technique is currently the most effective way to store large quantities of electrical energy in the form of energy operation, but the cost of capital and the presence of appropriate geography critical factors for the decision.

With energy management, well to pump storage hydroelectric systems for controlling the frequency of food production and security of reserve magnetic power generator. Thermal plants are much less able to responds in the sudden changes in electricity demand, the frequency and voltage to cause instability. Pumping stations, like other water plants can respond to changes within seconds to load with pumped storage hydroelectric system.

Although the automotive industry is a vigorous sponsor of research and development in vehicle efficiency technology—worldwide, nearly $20 billion U.S. worth in 1997—governments throughout the world sponsor additional automotive R&D, both separately from and in partnership with the industry. This work focuses primarily on four areas: emissions reduction, safety, fuels, and fuel economy. Within the past few years, government sponsorship of automotive R&D has moved sharply in the direction of attempting to advance the performance and cost-effectiveness of automotive fuel cells vehicles, which address three of the four areas: emissions, fuels, and fuel economy.

Magnetic generator motor supplies green and renewable energy. The energy created is very environmentally friendly and healthier for us and our next generations. You can also build a magnetic generator motor that can be set in motion deliver enough energy to power your home with these simple few steps. (more…)

Electricity is the flow of electric charge. This is happened if an electric current flow through a conductor likes copper wire. In this circumstance, the electrons flow from copper forced very slowly in one way for DC (Direct Current). In the AC (Alternating Current) the flow swings back and forth. The spreading electrical power through movement and vibration of electrons inside metallic conductors is very similar to sound waves transmitted from the vibration of air molecules. (more…)

The question has long been not whether or not to reduce air pollution, but by how much and by what means. Since the extent of the reduced discomfort and illness is not clear—and the measurement of peoples’ willingness-to-pay (WTP) for reduced discomfort and illness is uncertain—it is not easy to know how much the pollution should be reduced. But it has always been clear that reducing automotive air pollution had to be part of the overall strategy. (more…)

Being energy self sufficient is the wave of the future. As the available resources shrink, and the demand for energy grows, power companies are finding it more and more difficult to meet the power demands of its customers. There is talk now by most of the major utilities that if consumption keeps up at the current pace then they will be forced to have rolling black outs in order for them to conserve energy and stave off having to build new facilities. Think of it! Being told that you will not have power for several hours in the day, every day of the week! (more…)

World energy use has increased steadily over the past several decades. Much of the growth in world energy consumption has been concentrated on the use of fossil fuels (oil, natural gas, and coal). This trend is expected to continue over the foreseeable future. Industrially mature nations will continue to rely on fossil fuels to meet their energy needs for all end uses, but the greatest rate of energy use is projected to occur in the emerging economies of the developing world.
