This Batteries That Charges On Air EEE Final Project Report examines the properties of this unique system in terms of the effects of solubility’s of reactants and products in both non aqueous and aqueous electrolyte solutions.

The carbon based Li-ion batteries used currently fall short in meeting the requirements of utilization for renewable energy, electrification of transportation, smart grid and portable devices with regard to energy density, power density and cost. Metal/air batteries use oxygen directly from the atmosphere to produce electricity. The cathode active material, oxygen, does not have to be stored in the batteries, which allows for higher total energy capacity in a smaller designed package. Very high energy density can be achieved due to essentially unlimited cathode capacity. Our model predicts that the overall theoretical energy density of polymer electrolyte Li/air battery could be as high as 2790 Wh/kg and 2800 Wh/L, which is comparable to gasoline-air combustion engines. In past decades, various metal/air batteries have been investigated; however, three major challenges still prevent Li/air batteries from practical application. The oxygen reduction and evolution both take place on the cathode and the effective and long-lasting bi functional cathodes have not been developed yet. In order to reduce the products of the discharge, such as Li2O2 and Li2O, effective catalysts have to be discovered. Lastly, Li2O2 or Li2O are not soluble in the non-aqueous electrolyte currently used by researchers. They will clog the pores of the cathodes and eventually seize the cell. Focusing on these issues, we have conducted our initial investigation on cathode architecture, catalyst, electrolyte and the performance of the Li/air cells developed in out lab. We will discuss our results and share our vision for the future of this technology.

Batteries That Charges On Air EEE Final Project Report Conclusion:

The lure of extremely high specific energy and specific capacity is the impetus for recent advanced research on Li-air batteries. In non aqueous electrolyte solutions, the specific capacity of the Li-air cell is limited by the precipitation of lithium oxides within the cathode and the solubility of oxygen in the electrolyte solution which affect the transport of oxygen within the interior of the air cathode.

The Project Report On Automated Electricity Meter aims to move away from the traditional method of manual reading of electricity meters in which an individual has to physically record the reading. Instead the project proposes to successfully be able to take the meter reading automatically without having a person be physically present while taking the reading, thereby reducing manpower requirement.

An Automated meter is an advanced meter (usually an electrical meter) that records consumption at all instants and communicates the reading information via wireless network back to the central system for monitoring and billing purposes (telemeter) as per the requirement and regulation of the energy supplier. It enables two-way communication between the meter and the central system. Automatic electricity meter reading system is implemented, which provides cost-effective, reliable and interference free data transfer between remote meter reading units and the electric utility control center. The meter reading and management processes are free from human involvement. Based on the existing telephone networks, it is very flexible for utility companies to access, service and maintain this meter reading system. A user friendly and window-based user interface is designed which fully utilizes the personal computer’s terminate and stay resident programming techniques to achieve communications between the remote meter reading units and the personal computers in the electric utility control center.

Project Report On Automated Electricity Meter Conclusion:

The proposed system for energy billing is automatic without human intervention and consumer can directly know the amount he has to pay .So it is both consumer and EB friendly.

In future, this system can be improved by some additional features meeting the consumer requirements like emergency signal from the EB station employees; bill payment acknowledgement alarm etc., by just replacing the transmitter in the consumer side with a transmitter and receiver antenna. The receiver micro controller can be made designated for some other applications also.

This Project Report On Analysis Of Low Dynamic Power Listening Schemes In Wireless Sensor Networks contains general methods for designing low-power wireless sensor network. Various sources of energy consumption in these networks are here and discuss techniques to alleviate the present consumption of energy. Wireless sensor networks are widely used in many important areas such as target detection and tracking, environmental monitoring, industrial process control and tactical purposes.

Wireless sensor networks have used in a variety of applications and has become an attractive location for researchers in recent years. Because of the limited energy storage capability of sensor nodes, energy consumption is one of the most difficult aspects of these networks, and different strategies and protocols to deal unattended with this area. As nodes in wireless sensor networks, usually with a limited power source, energy-efficient operation of the nodes is very important. Although energy savings are appropriate in the communication in different layers of the TCP / IP protocol will be carried out save energy at MAC layer is found, the most effective agent because of its ability, the radio can be controlled directly. Therefore, a permanent network of wireless communications to ensure the sensors, we are in need of a MAC protocol that is capable of energy efficiency is overheard by maximizing the amount of sleep, listen to minimize idling and improve and eliminate the hidden terminal problem or a collision of data packets. In this paper we examine the available energy-efficient MAC protocols for sensor networks emphasize their energy-saving methods.

Project Report On Analysis Of Low Dynamic Power Listening Schemes In Wireless Sensor Networks Conclusion:

It is mainly due to stringent resource constraint both in sensor nodes and in wireless media. Several energy-efficient medium access control protocols both contention-based and reservation-based for the wireless sensor network that have been proposed by the researchers are presented in this report. The design of an optimized MAC protocol for energy efficiency also depended on the actual application. However, no specific MAC protocol has been accepted as a standard. Another reason is the lack of standardization at lower layers (physical layer) and the sensor hardware.

This EEE Project Report On Advances In Renewable Energy Source  study of renewable energy sources is an important topic in the field of the combustion science. Aim of this report is to report some preliminary results concerning the solar, wind, bio-fuels, geothermal energy & their commercialization.

Power deregulation, which resulted in restructuring of the power industry, and shortage of transmission line capacities have led to increased interest in the use of distributed generation (DG) sources, mainly at the distribution level near load centers, for support of the utility grid. Moreover, technological advances in renewable (wind, solar) and other alternative energy DG (AEDG) sources, e.g. micro turbines and fuel cells, coupled with environmental concerns over the use of conventional steam power plants have developed especial interest in their use. However, because of the non-dispatch able nature of renewable energy and slow nature of some alternative energy power generation sources, e.g. fuel cells, multi-source operation of these sources and/or their parallel operation with a storage device is necessary to make their operation more reliable. This paper discusses the need for multi-source operation of AEDGs. It reviews four different AEDG sources – wind, solar photovoltaic (PV), micro turbine, and fuel cells – and discusses their multi- source operation for better power management and reliability.

EEE Project Report On Advances In Renewable Energy Source Conclusion:

Recent advances in renewable energy technologies indicate they may have a significant role as a future source of energy supply. However, there are several misconceptions surrounding current renewable energy technologies, in particular that fossil fuels are running out, that increased renewable energy use will reduce on imported energy and that renewable energy, by the simple fact of being renewable, is always more environmentally friendly. Deeper exploration of these issues reveals much uncertainty of future conditions. Faced with such uncertainty, broad based market mechanisms are likely to provide the best means to achieve desired environmental outcomes and to stimulate further development of clean technologies. There is a danger that prescriptive approaches could lock the economy into a high cost emissions reduction path.
