Generation Unit

In this project, a mobile, renewable, and versatile generation unit is designed. It utilizes solar and wind energy resources which make it usable in any location. The power source can effectively support emergency situations, such as hurricane, wildfire, earthquake, as well as special events such as remote training. It can provide at least 3.7kW to run multiple tools used during search and rescue situations. Specifically, the unit has seven 5-VDC 2-A DC/USB outlets, two AC 120-V 15-A outlets, and four 6-W LED lights which serve diverse equipment and devices. Its battery system could potentially run on its own for 12 hours when supplying 1kW. The unit is housed in a normally-sized trailer with the total weight of around 10,000 lbs. It is very versatile as it can be towed by any popular truck to diverse locations. Simulation has shown that the unit works properly and all design expectations have been met. The use of this green power source will help save lives while keeping our air clean

This paper reviews the piezoelectric energy harvesting from mechanical vibration. The recent development in the microelectronic devices and wireless sensor networks (WSNs) requires continuous power source for better performance. Many researchers have been done to develop a permanent portable power source for microelectronic devices. Micro energy harvesting (MEH) consists of two basic elements; freely available energy and transducer. Energy is everywhere around us in different forms. The energy conversion ability of piezoelectric energy harvester is high among different MEH techniques. A cantilever type piezoelectric energy harvester under different shapes is mostly studied in the last few years. The output of piezoelectric harvester depends upon the deflection produced, more deflection led to more electrical output. The deflection in cantilever beam under different shapes is different. This review paper presents a comparison of different piezoelectric cantilever beam shapes and output generated analyzed in the last decade.
