The cost of diesel is increasing tremendously, also the amount of fossil fuel from our earth gets decreases day by day. In this current situation, we need an alternative fuel instead of diesel fuel. Many of the researchers have successfully worked on generating energy from several alternative sources including solar and biological sources such as the conversion of some renewable agricultural products into fuel.

Complete blindness is the total absence of light, but partial blindness represents the lack of integration in the growth of the optic nerve or visual center of the eye. In some cases lens, occupied glasses will help to improve partial blindness. Low vision cannot be corrected by visual aids such as glasses and contacts. In those situations, it is too difficult to find or detect obstacles in front of them, which makes it dangerous. They need some aid to feel safe while navigating. Conventional Blind canes are widely used for assistance, but it has too many limitations. Thus the current scenario needs a technologically developed cane. Thus, Smart cane comes as a proposed solution for visually impaired people. In this experimental work, we implanted a simple, economical, and user-friendly smart blind guidance system. This system is designed to improve the mobility of both visually impaired and blind people, and to remove the curse of blindness, to make them selfdependent to do their daily routines. The proposed work includes the design of a lightweight adaptable cane with multiple sensors connected to an Arduino board, along with a handle head and sticks elongator. A conventional white cane forms the main base frame of the device, ultrasonic and infrared sensors are mounted at appropriate locations to detect obstacles and it can scan a predetermined area, both known and unknown locations around blind by emitting-reflecting waves with the help of that blind stick. The equipped sensors send signals to an Arduino programmed board, which communicates with the alarm unit that comprises a buzzer and vibrator and gives some recorded audio clips to navigate the blind people safely. An audio jack is also available in the blind cane whose presence is not found in other conventional canes. The system can also control the peripheral components that alert the user about the obstacle's shape, material, and direction. The device is lightweight and is been powered by a battery. Thus the system is easy to use and is an innovative reasonably priced solution to blind and visually impaired people. The power consumption is too low, and the stick is economic over the conventional one.

This work includes the use of crude coconut oil for the production of renewable biodiesel fuel as an alternative to conventional diesel fuel. The preliminary results of using a homogenous catalyst (KNO3) for crude coconut oil transesterification with methanol. It was found that, from the experimental investigation, the catalysts (homogenous) called KNO3 with methanol shows much higher activity than that of the heterogeneous catalysts and it shows more similar properties with diesel fuel. The results obtained from the chemical test and physicochemical properties clearly prove the above-mentioned statement. The chemical tests such as GCMS and FT-IR clearly shows the volatile components and functional groups present in the oil respectively. Finally, physicochemical properties include, Fire point, Flashpoint, density, and viscosity were analyzed. It was found to be, the transesterified crude virgin coconut oil biodiesel has properties similar to that of the diesel fuel, which was analytically determined through some basic properties of biofuel. Since the obtained transesterified biofuel can be used as an alternative fuel for diesel engines. The several reports and find outs depict the efficiency of the transesterified biofuel mainly depends upon the amount of catalyst adding and type of catalyst present, whether it is homogenous or heterogeneous with methanol. Finally, a comparison is made with the diesel fuel, to determine the optimum blend percentage of catalyst for better and efficient one.
