Abstract: Two hundred years ago, the world experienced an energy revolution that launched the Industrial Age, The catalyst to this epochal shift was ordinary black coal, an energy-rich hydrocarbon that supplanted wood as the primary fuel. A century later, the industrialized world's thirst for energy had increased tremendously. Petroleum and natural gas were exploited as versatile and high quality energy products, and soon joined coal as principal fuels. Fifty years later, scientists tapped uranium to fuel nuclear reactors and provide atomic energy. Today, cheap energy is the lifeblood of our society. But there is a dangerous dark side to relying on non-renewable resources like coal, oil, natural gas, or uranium to supply our growing energy demands, these finite sources are concentrated in certain region of the world and would soon get exhausted. The supply of these fuels is physically limited, and their use threatens our health and environment. Fears of global warming aside, burning fossil fuel releases chemicals and particulates that can cause cancer, brain and nerve damage, birth defects, lung injury, and breathing problems. India is an agricultural country, and 60% of their total population lives in villages and 50% of them are using Kerosene and Biomass as source of energy for cooking food. These fuels generate harmful gases that are hazardous for human as well as for our environment also.Kerosene is a nonrenewable source of energy, and it is most popular domestic fuel in rural parts of India. Kerosene is meant to be used as a cooking, lighting or heating fuel this is heavily subsidized so that it can be purchased more easily by India's poor. So. we are in need to provide them a new source of energy which could be cheap, renewable as well as eco-friendly to. In India vegetable oils as well as non-edible oils is produced domestically which helps to reduce costly petroleum imports. Development of the bio-fuel industry would strengthen the domestic and particularly rural, agricultural economy. Non- edible oils like Karanja, Jatropha, cottonseed etc are biodegradable and can be made from agricultural crops and or other feed stocks that are considered as waste. Non- edible oils like Karanja, Jatropha have great calorific value and can be used as fuel. In country like India, there is a greater need to explore the use of Non- edible oils as fuel because of the possibility of large production capacity of these oils and producing it near the consumption points. Kerosene is a non-renewable source of energy, and it is most popular domestic fuel in rural parts of India, but with ever increasing cost of kerosene and huge subsidies by the government kerosene is fast diapering from rural households. In the present innovation a new type of horizontal pressurized is developed which consist of two tanks. In one of the tank kerosene is filled and in another tank Non-edible oil is filled. Initially the stove is started with kerosene,, after about two minutes when the preheating coil is heated up the valve is slowly closed and valve is slowly opened simultaneously, and finally valve 1 is completely closed and valve 2 is completely open. Now the stove runs completely on non-edible oil. The tests on this stove are conducted for thermal efficiency and it is identified that the stove while running on straight vegetable oils has comparable thermal efficiency with the stove run on kerosene.
