The generation of electric power and its storage is a major cause of concern in the present era of development and innovation. The ideologies regarding various environment friendly and conservative methods for generation of electricity were put forward by various scientists and even students all over the world and the efforts put forward for the development of an efficient method are limit less. In the present scenario, there is a lot of wastage of energy from simple aspects such as energy wasted or expended during walking, running etc., to large quantities of energy wasted during the process of working of engine due to friction and heat generation. The concept of power generation from speed breakers solely emphasize the concept of electric power production by utilizing the energy of vehicles that otherwise would be wasted during its travel over a bump, due to reduction in speed. A crank and slotted lever mechanism, when operated from a reciprocating input due to the transverse movement of the bump when a vehicle passes over it, would produce electric power when linked with a generator which is capable of lighting a street lamp. This mechanism for power generation utilizes the weight of vehicle travelling on the bump for its downward motion and hence, the energy or electric power generated comes from an input which has an ever increasing trend, i.e., the number of vehicles on the roadways. Hence the project as a whole would be a much efficient method for power generation. The innovations that can be done to this mechanism for more power utilization and efficiency are limitless and hence, its applications and future scopes are those which are worth working for. The implementation of this project would put a brake to the increase in exhausting of electric power generation sources such a nuclear power plants, hydro-electric power plants and if implemented judiciously, would make the possibility of free electric power, a reality.

Government of India doesn’t want to compromise with environment pollution, so it makes the strict emission norms for IC engine. Diesel engine is well known for fuel economy and efficient operation but only problem is engine emission .to fulfill the future emission norms HCCI Bifuel engine is one of the best option, so it can operate diesel engine with CNG. The use of CNG in HCCI engine along with pilot diesel injection, the emissions has been decreased drastically. Homogeneous mixing of fuel and air leads to cleaner combustion and lower emissions. The premixed lean mixture reduces soot particles. By optimizing operating parameter like mixture strength and load we can obtain less emission and better fuel economy. In experimental work there is use of CNG injection at high pressure and fixed amount of diesel for initiate combustion only and then varying amount of CNG for optimization of low emission and higher performance for particular load.

In the current world scenario, the main emphasis is laid on the judicial use of energy, which is also the one word definition of energy conservation. This can be done by research on the energy consuming devices in various fields. In cryogenic engineering, one of the most important machine is a rectification column, and it consumes high amount of energy, hence its heat loss analysis must be done, in order to get exact amount of heat leakage at various stages. The air separation process requires a very tight integration of heat exchangers and separation columns to obtain a good efficiency and all the energy for refrigeration is to be utilized at its best to get maximum possible efficiency. When the main thermal losses in the system are known by the CFD analysis use to analyze the heat losses, and if the heat losses at various stages and points are known they can be minimized by using suitable insulations and the cost can also be minimized.

Pages: 246 - 251
Conveying of powder like substance in industries are used by conventional conveyors such as bucket elevators, screw conveyors. In case of volatile or expensive materials such as Titanium dioxide, which is used mainly in paint industries, usage of conventional conveyors is not economical. Titanium dioxide powder is used for the production of inks, plastics, textiles, ceramics etc. It is commonly produced by the chloride route process of Rutile grade pigment. Due to the fine powdering nature of the material this system has certain problems like frequent spillage and fine powder escaping. Though some amount of powder is regained with the help of filtrate recovery process, this process is time consuming and expensive. Thus this spillage and other associated troubles are found to be one of the serious problems faced by the industries. Here fully refined powder material is wasted whereby the industries suffer huge losses both directly and indirectly. Hence this study is to determine the reasons behind this problem and to suggest a suitable remedy. As a long term solution, replacement of the conventional conveying system with a Pneumatic conveying system was suggested.

Fertilizer is any material of natural or synthetic origin used to enhance the growth of plants. Fertilizers are commonly used for growing all corps, with application rates depending on the soil fertility, usually measured by a soil test and according to the particular crop. Fertilizer spreaders for large scale farming are tractor mounted. For small scale uses, it not possible to use costly tractor mounted spreaders. Conventional spreading of fertilizers for small scale farming are by hand. It has some problems like uneven spreading of fertilizer, more time consuming, high human effort. The farmer have to carry heavy bags throughout the spreading process. So it is necessary to develop a fertilizer spreader for small scale farming. The proposed fertilizer spreader uses a trolley type of mechanism. The main part is spreader disk, which helps for uniform spreading. The feed for the disk is from the wheels of the trolley using gear transmission. By using this spreader, a lot of time can be saved, human effort used for carrying heavy bags of fertilizer is reduced and wastage of fertilizer can also be avoided.

Pages: 255 - 257
The project aims at solving the alarming issue of water scarcity and sterilization by developing a system that would utilize solar energy which is a renewable source for the purification of unclean water from various water bodies to produce pure potable water. This system involves an evacuated tube containing water which is superheated using solar energy under elevated pressures to increase the boiling point. This high pressure superheated water is used for steam sterilization in an autoclave. The steam after sterilization can be condensed to generate pure water using a copper coil heat exchanger. This system can be effectively used in rural as well as coastal areas where energy sources other than solar are limited to generate potable water.In this process, water is pressurized to raise its boiling point. When this occurs, steam will be created at a temperature higher than 100°C. In fact, in order to fully eliminate all prions and bacteria associated with disease, saturated steam needs to be at least 121°C when in contact with the equipment being sterilized. A solar autoclave provides an alternative solution to this problem. Using only solar radiation, a solar autoclave can provide remote health clinics with an inexpensive, efficient way to sterilize medical equipment. The steam generated inside the autoclave is condensed to give pure water using a simple heat exchanger.

Pages: 283 - 286
The aim of this paper is to develop a zero turning vehicle. Instead of operating by gear system, we are using pneumatic system for operation of this vehicle. Replacing two wheel drive by four wheel drive makes more convenient for the vehicle to take the turn. Conventional steering involve either the Ackerman or Davis steering system which has major disadvantage that it can't take minimum radius turn. We try to solve the problem of turning radius by new concept of zero turning vehicle with mechanical linkages and pneumatic cylinders. The main purpose of this project is to reduce the turning radius and turning space by rotating at same place without leaving its centre of gravity. In this system, the wheels connected to the front axles are turned opposite to each other, and so are the wheels connected to the rear axle. The wheels on the on left half vehicle rotate in one direction and the ones on the right half of the vehicle. To overcome problem like vehicle maneuvering on narrow roads and during parking this system has been proposed.
