The environmental impact of ICE automobiles in the late twentieth and early twenty-first centuries prompted the development of electric vehicles. Electric vehicles have numerous advantages over traditional internal combustion engines (ICE) vehicles, including the fact that they emit no carbon dioxide into the atmosphere. With many advantages of electric vehicles over traditional ICE vehicles, the world is moving toward EVs as a new improved means of transportation. Electric vehicles' tank to wheel efficiency is three times larger than ICE vehicles', and electric vehicles have very low running and maintenance costs. Even though electric vehicles are the best alternative, they do have significant disadvantages that are listed in the problem statement. Our proposal aims to bridge the gap between pure electric and traditional ICE automobiles by combining the primary benefits and advantages of both technologies. The project's main goal is to convert any existing ICE car into the most efficient vehicle possible. Our car can basically run on two distinct independent sources of energy, or even a combination of both. It can function as a pure electric vehicle, a pure ICE vehicle, or a hybrid AWD vehicle (where high amount of power is required). It has been shown that the average city dweller does not drive his or her car for more than 25 kilometers per day, and that the vehicle is parked the majority of the time. As a result, that individual can traverse that distance in pure electric mode, and our vehicle's solar charging mechanism will recover/recharge the energy expended while on the road. As a result, the person will be able to use our vehicle for free to generate sustainable energy. The use of ICE vehicles is rapidly increasing pollution in the environment; even pure EVs are an indirect source of pollution because the bulk of power is still generated by burning coal, thus our vehicle's use will undoubtedly make a significant difference.

Misalignment and unbalance are the most probably common cause of machine vibration. Vibration monitoring is a useful technique for application to rotating machinery and provides valuable information regarding symptoms of machinery failure which may avoid costly breakdown. Understanding and practicing the fundamentals of rotating shaft parameter is the firststep in reducing unwanted vibration. Experimental studies were performed on two rotor dynamic test apparatus to predict the vibration spectrum for different faults. The experimental test rig was designed and tested for misalignment and unbalance condition. The rotor shaft accelerations were measured at 1000 rpm speed using four channel vibration FFT (Fast Fourier Transform) analyzer. The experimental frequency spectra were obtained for misalignment and unbalanced condition leading to reliable diagnostic information.
