This document summarizes a study that tested the performance and emissions of a diesel engine fueled with blends of diesel, jatropha biodiesel, and ethanol. Ten different blends ranging from 90-80% diesel, 0-15% biodiesel, and 0-15% ethanol were tested. The engine's performance was evaluated by measuring brake specific fuel consumption and brake thermal efficiency. Emissions of carbon monoxide, nitrogen oxides, and unburned hydrocarbons were also measured. Testing showed that most biodiesel and ethanol blends increased fuel consumption but slightly improved efficiency compared to diesel. Emissions varied depending on the load and blend, with some blends performing better than diesel in reducing certain emissions

A 'gasoline-electric hybrid car' or 'Plug in hybrid electric vehicle' is a vehicle which relies not only on batteries but also on an internal combustion engine which drives a generator to provide the electricity and may also drive a wheel. It has great advantages over the previously used gasoline engine that drives the power from gasoline only. It also is a major source of air pollution. The objective is to design and fabricate a two wheeler hybrid electric vehicle powered by both battery and gasoline. The combination of both the power makes the vehicle dynamic in nature. It provides its owner with advantages in fuel economy and environmental impact over conventional automobiles. Hybrid electric vehicles combine an electric motor, battery and power system with an internal combustion engine to achieve better fuel economy and reduce toxic emissions.
In HEV, the battery alone provides power for low-speed driving conditions where internal combustion engines are least efficient. In accelerating, long highways, or hill climbing the electric motor provides additional power to assist the engine. This allows a smaller, more efficient engine to be used. Besides it also utilizes the concept of regenerative braking for optimized utilization of energy. Energy dissipated during braking in HEV is used in charging battery. Thus the vehicle is best suited for the growing urban areas with high traffic. Initially the designing of the vehicle in CAD, simulations of inverter and other models are done. Equipment and their cost analysis are done. It deals with the fabrication of the vehicle. This includes assembly of IC Engine and its components. The next phase consists of implementing the electric power drive and designing the controllers. The final stage would consist of increasing the efficiency of the vehicle in economic ways.

Biomass:an alternative energy source ppt
Biomass is a renewable energy source derived from living or recently living organisms. It includes materials like wood chips, agricultural waste, and human/animal waste. Biomass can be converted into energy through processes like combustion, anaerobic digestion, and fermentation to produce electricity, heat, or fuels like ethanol and biodiesel. While biomass has benefits as a renewable alternative to fossil fuels, it also faces challenges in terms of production costs and potential environmental impacts like air pollution and soil erosion if not managed properly.

"Does Foreign Direct Investment Negatively Affect Preservation of Culture in the Global South? Case Studies in Thailand and Cambodia."
Do elements of globalization, such as Foreign Direct Investment (FDI), negatively affect the ability of countries in the Global South to preserve their culture? This research aims to answer this question by employing a cross-sectional comparative case study analysis utilizing methods of difference. Thailand and Cambodia are compared as they are in the same region and have a similar culture. The metric of difference between Thailand and Cambodia is their ability to preserve their culture. This ability is operationalized by their respective attitudes towards FDI; Thailand imposes stringent regulations and limitations on FDI while Cambodia does not hesitate to accept most FDI and imposes fewer limitations. The evidence from this study suggests that FDI from globally influential countries with high gross domestic products (GDPs) (e.g. China, U.S.) challenges the ability of countries with lower GDPs (e.g. Cambodia) to protect their culture. Furthermore, the ability, or lack thereof, of the receiving countries to protect their culture is amplified by the existence and implementation of restrictive FDI policies imposed by their governments.
My study abroad in Bali, Indonesia, inspired this research topic as I noticed how globalization is changing the culture of its people. I learned their language and way of life which helped me understand the beauty and importance of cultural preservation. I believe we could all benefit from learning new perspectives as they could help us ideate solutions to contemporary issues and empathize with others.STREETONOMICS: Exploring the Uncharted Territories of Informal Markets throug...

Alternative Fuel
- 2. Ethanol Ethanol is made by distilling crops, such barley, in order to produce alcohol; this can then be mixed with gasoline in order to reduce the emissions. The government would need to supply the funds needed for the crops to distill, as well as for the labs where the ethanol and gasoline would be mixed. The infrastructure needed is fields designed for the growth of crops to be distilled will need to be created, as well the labs for the combination of the ethanol and gasoline.
- 3. Advantages/Disadvantages of Ethanol Advantages Ethanol is easily renewable. Ethanol will help clean up the emissions when mixed with gasoline. Disadvantages Using Ethanol as a fuel source could have a negative impact on the food market.
- 4. Electricity There are two ways to use electricity to supply energy: battery cells, and fuel cells. Battery cells store energy in batteries that are able to be recharged; fuel cells combine hydrogen and oxygen to produce the electrical energy needed to power the car. The government would need to supply the funds for the battery cells and/or the fuel cells, for the public charging stations, and for the factories where these cells would be manufactured. The infrastructure needed is the factories for manufacturing the cells, as well as the public charging stations for battery cell run cars.
- 5. Advantages/Disadvantages of Electricity Advantages Electricity has been proven very efficient. When using fuel cells, no chemical combustion is needed in order to produce electricity, which means no pollution emissions. Disadvantages In order to generate the electricity needed to power the cars, we still rely on natural gas and coal, which leave large carbon footprints. Electric cars can only travel a short distance before needing a recharge.
- 6. Biodiesel Biodiesel is oil from vegetables and animal fats; in its pure form, it can be burned by specifically designed engines. It can also be combined with petroleum to be used in currently existing engines. The government would need to supply the funds needed for manufacturing of the new designed engines, and/or for the labs needed to combine biodiesel with petroleum. The infrastructure needed is labs for the combination of biodiesel with petroleum, as well as factories for the manufacturing of the specifically designed engines needed to convert pure biodiesel into energy.
- 7. Advantages/Disadvantages of Biodiesel Advantages Biodiesel is safe to work with, unlike some other alternative fuel sources. Biodiesel is biodegradable, therefore reducing emissions. Disadvantages We currently lack the infrastructure required to work with biodiesel.
- 8. Hydrogen Hydrogen can be used in two ways: in electrical fuel cells, and in natural gas. In fuel cells, hydrogen is combined with oxygen, which created a chemical reaction that results in energy that can be used similarly to electricity. Hydrogen can also be mixed with natural gas, which can be processed by certain combustion engines. The government would need to supply the funds needed for the hydrogen, as well as for the labs to either combine the hydrogen with oxygen for fuel cells, or with natural gas. The infrastructure needed is labs for the utilization of the hydrogen into either fuel cells or into a natural gas mixture.
- 9. Advantages/Disadvantages of Hydrogen Advantages Hydrogen is an entirely clean source of energy, with zero emission. Earth has an unlimited supply of hydrogen. Disadvantages Hydrogen is expensive to obtain in large quantities. Hydrogen can be difficult to work with.
- 10. My Choice: Biodiesel If I had to choose an alternative fuel to use in vehicles in the next 10 years, I would choose biodiesel. Since it is created from vegetable oils and animal fats, it would not only help reduce carbon emissions, it would also help recycle our everyday waste. Biodiesel is also safe to use, unlike hydrogen, which means that it wouldn’t require special equipment to create it, making it less costly and more realistic. While there are many other alternative fuel sources, for example solar power, from the four listed in this power point, I believe that biodiesel is the most sustainable option.
