Project Mind Map This trimester I had the chance to participate in a green engineering project, we name it Eco car, talks about trading gas cars to byfuel or natural gas combustible. it reduces in a great amount the emission of CO2. I was the Leader investigator of the project. Iwas interested in this subject because here in Venezuela the conversion is for free.

This is the mind map of our Project. Eco Car. you can find it at

domingo, 1 de noviembre de 2009 This is the name of our project. it's about moving green, using vehicles that are eviromental friendly, and the CO2 emissions are less than a regular vehicle. Bi-fuel vehicles are vehicles with multifuel engines capable of running on two fuels. On internal combustion engines one fuel is gasoline or diesel, and the other is an alternate fuel such as natural gas (CNG), LPG, or hydrogen. The two fuels are stored in separate tanks and the engine runs on one fuel at a time, unlike flexible-fuel vehicles ("dual-fuel"), that store the two different fuels mixed together in the same tank, and the resulting blend is burned in the combustion chamber. Bi-fuel vehicles have the capability to switch back and forth from gasoline or diesel to the other fuel, manually or automatically.
*Bi-fuel vehicles (subject, noun) are(verb) vehicles(noun) with(prep) multifuel(noun) engines(noun) capable(adjective) of(prep) running(noun) on(prep) two(noun) fuels(noun) PRESENT
*The(art def) two(noun) fuels(noun) are(verb) stored(noun) in(prep) separate(verb) tanks (noun) SIMPLE PRESENT

The most common technology and alternate fuel available in the market for bi-fuel gasoline cars is natural gas (CNG), and it is used mainly in Europe, where Italy currently has the largest number of CNG vehicles. They are also used in South America, where these vehicles are mainly used as taxicabs in main cities of Brazil and Argentina. Normally, standard gasoline vehicles are retrofitted in specialized shops, which involve installing the gas cylinder in the trunk and the CNG injection system and electronics. According to Natural Gas Vehicle Coalition data, dedicated natural gas vehicles can reduce exhaust emissions from diesel engines by up to the following percentages: Carbon monoxide (CO) 70% Non-methane organic gas (NMOG) 87% Oxides of nitrogen (NOx) 87% Carbon dioxide (CO2) (below gasoline emissions) 20%

Combustion n. A chemical change, especially oxidation, accompanied by the production of heat and light. Multifuel: n. sometimes spelled multi-fuel, is a term applied to any type of engine, boiler, or heater or other fuel-burning device which is designed to burn multiple types of fuels in its operation. Retrofitted v. Fit To fit into or onto equipment already in existence or service.

I am replying to your advertisement of this date offering a position as an Industrial engineer. I believe that my education, skills and work experience are appropriate for the position.

As my resume demonstrated, I have been working as a manager for the Grocery Department for a recognize Supermarket in the local area. where I am responsible for designing work schedules, improving the manufacturing process in various areas, I also worked on cost analysis, systems analysis and work & job design in order to provide best value for our customers and associates. I also have the knowledge of Planning space requirements, workflows, designs layout of equipment and workspace for maximum efficiency and safety. Planning and design staff concerning product design and tooling to ensure efficient production methods.
I worked with management, engineering and other staff regarding manufacturing capabilities, production schedules, and other considerations to facilitate production processes and ensure excellent service. Worked with vendors to provide manufacturing specifications and arrange for purchase of necessary equipment and materials. I can manage project work in an organized and timely manner. I have an excellent ability to identify problems, analyze options, and apply solutions. I can also provide strong communication, documentation, listening, and interpersonal skills. I think a have the ability to fill the position you are offering and do an excellent job.

How to Stop Climate Change? It takes more than one person to stop global warming and climate change. The nature can do A lot by herself, but we can help too. Find out what you can do. Hey It's your wold too!

Industrialised countries need to reduce their greenhouse gas emissions 25-40% by 2020 (compared to 1990 levels) and 80-95% by 2050 to have a 50:50 chance of limiting warming to 2° C and avoiding dangerous climate change, according to the UN Intergovernmental Panel on Climate Change (IPCC). This means taking action to reduce emissions now.
The greatest potential for tackling the greenhouse gas emissions generated by our energy consumption (whether for electricity, heating and cooling, or transport) is offered by energy saving and efficiency: using energy better. As well as being the safest and most effective way to deliver emissions reductions, this demand-side approach would reduce our unhealthy dependence on imported fossil fuels and save money for consumers and businesses.
*GREEN POWER There is enormous potential to generate environmentally-friendly energy from renewable sources such as wind, solar power, hydro, geothermal and biomass. Many of the technologies have already proven to be economically viable and, in an era of high oil prices, more will become so. Ensuring that Europe realises its renewables potential will: reduce our dependence on imported energy and deliver much -needed jobs and growth, as well as playing a central role in our response to climate change.
*STOP THE USE OF FOSSIL FUEL Our insatiable appetite for energy from fossil fuels is the main cause for the current climate change crisis. The rapid growth in the extraction and burning of fossil fuels (like coal, oil and natural gas) has led to a massive increase in the release of climate change-causing greenhouse gases, notably CO2. We need to rapidly scale back our use of this dirty energy. To avoid dangerous effects of climate change, we need to transform the global energy system away from one dependent on fossil fuels to one that is based on new renewables, energy efficiency and energy conservation. This means finishing with outdated and dirty energy sources like coal and oil by 2050.
*NUCLEAR NO SOLUTION Nuclear power is not a solution for climate change. The nuclear industry is in global decline and any attempts to reverse this decline would be both overly costly and would not be realised in time to contribute to the urgently-needed greenhouse gas reductions. This is not to mention the massive risks associated with nuclear power and the unresolved question of how to safely deal with dangerous radioactive waste. Globally about one third of the greenhouse gases are caused by the production of electricity. The world's 339 operating nuclear reactors provide only 16% of global electricity, 6% of commercial primary energy and 2.5% of the final energy in the world. Nuclear power worldwide generates less electricity than its decentralised no- and low-carbon competitors (renewables and fossil-fueled combined heat and power).
*MOVE GREEN The climate change impact of transport is continuing to grow, undermining progress being made across other sectors of the economy in reducing greenhouse gas emissions. Tackling this climate impact must be a top priority if we are to prevent dangerous climate change. This means changing our approach to how we get around. The transport sector is almost completely dependent on petroleum-based fuels (like petrol and diesel), which are a major cause of greenhouse gas emissions, as well as other pollution. Weaning ourselves off our dirty gas-guzzling habits is a real challenge, as increasing the share of renewable fuels in transport is not a viable option in the short-term. The real potentials for reducing the climate impact of the transport sector lie in shifting to soft mobility options and improving the efficiency of existing fuel-powered transport modes. Developing hybrid-electric engines offers a more realistic prospect of reducing our damaging dependence on oil imports and the emissions this generates.

I found this intersting wep page. I invite you to check it out and find out a climate change glossary, and a lot more info about this subject.
