...efficiencies of 70% are possible nowadays, along with a heat recovery possibility. SOFCs appear to be an important technology for the future as they operate at high efficiencies and can run on a variety of fuels, from solar hydrogen to methanol, from biomass to gasified coal and Hydrogel, Natural gas and Synthetic gas . As the technology develops, and if the cost of fossil fuels continues to rise, this clean, efficient alternative will stimulate the thermo mechanical engineers Why Lower Temperature SOFCs (≤ 600 ºC)
Metallic: Lower cost and greater reliability
Easier Sealing: Lower cost and greater reliability
Smaller Thermal Mismatch: Greater reliability
Less Insulation: Lower cost
Rapid Startup with Less Energy Consumption:
Lower cost and better performance
Portable/Transport applications
Transient Operation
Need higher conductivity electrolytes

    Microbial Fuel Cells use bacteria to convert waste into electrical energy. These bacteria break down almost any biodegradable organic waste including sewage and water waste and use it as fuel to generate power. Places like Penn State University and The Biodesign Institute in Arizona State University are already testing and improving this new alternative energy. According to Penn State University they have achieved in producing 1.5 watts per meter squared of amount of waste water taken in and believe that a large industrial plant will be able to produce near 0.8 watts per meter squared and will be able to support about 500 homes (9). This is a new technology that is being avidly researched, however it is not currently used in large industrial plants or treatment centers. However this new technology has already been funded by organizations like NASA, OpenCEL and NZ Legacy (7). Even a small prototype has been built by Australian Beer Company Fosters in May 2007; it has 12 modules and already produces carbon dioxide, electricity and clean water. (12). The usage of this energy is slowly increasing as more research has been invested into it and its advancements.

  • Water: Fuel to Think About

    1033 Words  | 3 Pages

    The chemical make up of water is perfect for creating fuel. When it is separated into it’s individual atoms, then oxidized as fuel to burn, it is 2.5 times more powerful than the gasoline we use today. Stanley Meyer and his brother developed a way to use a modulating current to efficiently break the water molecule up into its individual atoms using what he called a “water fuel cell assembly.” According to his patent the term “fuel cell” refers to the single unit in the invention that produces the combustible gases in accordance with the method stated in the patent (Meyer, 1989).

    ...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.

    Fuel is drawn from the tank by an in-tank or chassis-mounted fuel pump. The fuel pump is the device that draws the fuel from the fuel tank through the fuel lines, to the fuel filter and then to the engine’s carburetor or injectors. There are two types of fuel pumps: mechanical and electrical. The mechanical fuel pump is bolted on the side of the engine block or on the side of the cover of the timing gear.

    Biomass gasification is a process by which biofuel is produced. It has been used for over 180 years but in the last decades it has been reconsidered as an interesting technique due to the fact that oil supplies are decreasing. As mentioned before, gasification is a thermal process. Heat is added up in order to convert the organic mass to biofuel. The biomass usually undergoes drying, pyrolysis, partial oxidation and reduction. Nowadays the configurations used for gasification are three: fixed bed gasifier, fluidized bed gasifier and entrained bed gasifiers. The simplest configuration is the

    Now, what are electric vehicles really? Simply put, electric vehicles are vehicles that are powered by an electric motor instead of an internal combustion engine. Electric vehicles use electricity as the “fuel” instead of gasoline or some other combustible fuel. The electric motor in an electric vehicle converts electricity, usually from a battery pack, into mechanical power to turn the wheels. Major auto manufacturers are producing high-performance electric vehicles not only in the form of cars but also in a wide range of styles and sizes, including, mini-vans, sport utility vehicles and pickup trucks.

Therefore, because of the lack of readily available hydrogen fuel and the inefficient methods of producing hydrogen in a clean way, the use of fuel cell cars is highly improbable for now. However, if we are able to create apt methods of producing hydrogen without the aid of fossil fuels, we could enter an age of hydrogen within decades.

    For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
