earth much before any human being was born. They ruled the earth for over 165 million years‚ till 65 million years ago. They were huge monsters‚ even bigger than elephants. The word "dinosaur" was taken from a Greek word which means terrible lizard. But they weren’t exactly lizards. Lizards are one type of reptile and dinosaurs are another type. Not all dinosaurs were giants. Some dinosaurs were no bigger than small dogs. The smallest kind was about the size of a chicken. No human being has seen a living

development of a mixed fuel called HYTEST. Today‚ automobile manufacturers and DOE continue to work on hydrogen-powered ICEs. | Hydrogen/natural gas fueling (HYTEST fuel) of Ford Ranger‚ FSEC H2 Lab (Photo: S. Spencer) | There are four basic issues regarding hydrogen-fueled engines and vehicles: engine backfire and susceptibility of hydrogen to surface ignition‚ somewhat reduced engine power‚ high nitric oxide (NOx) emissions‚ and the problem of on-board storage of the fuel and safety.

Earthquakes‚ volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices)‚ landslides‚ glacier calving’s meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami. The effects of a tsunami are devastating. They are one of the world’s worst natural disasters that can hit a country. Tsunami damage is first caused by the

Alternative fuels‚ also known as non- renewable sources‚ are substances that can be used as fuels‚ other than conventional fuels. Conventional fuels include: fossil fuels (petroleum (oil)‚ coal‚ propane‚ and natural gas)‚ and nuclear materials such as uranium. [ 1] The fuels we use now are finite‚ meaning they have a limited life expectancy. This along with the toxic waste they produce has made environmentalist and government officials alike take precautionary steps so that we do not

Pre-heating Fuel for Charge Homogeneity to Improve Combustion Abstract – The idea of the automobile engine that people have is of one that is bygone. The automobile engine today is the pinnacle of engineering expertise‚ implementing the best of technologies and undergoing the best of manufacturing processes to make the closest possible achievement to perfection‚ from design to combustion. The art of perfection though starts much before the process itself. In case of the automobile engine

Human are the ones putting a huge impact on the carbon cycle. Humans are tearing apart important animal territory. they are tearing down trees and moving plants‚ in order to add house‚ expand and make buisneses. Since they are expanding the area and then bringing in more humans in return we use more of our fossil fuels increasing the carbon dioxide into the air. For example just recently near my house the were adding on to the hospital. That involves clearing out acres and acres of land just

Biofuels Biofuels are Fuels made from Biomass Biofuels are made from plants‚animals‚ or their waste products. Here I have listed three examples of biofuels beneath. 1 Micro-organisms decompose waste materials to produce biogas. 2 Biogas is usually about 70% methane and somewhere between 20 and 30 % carbon dioxide 3 the way we use it to generate energy is to burn it to heat up water which will then turn a turbine to produce electricity. It is also heard of to heat the water to steam which

Results of primary use for gasoline‚ gasoline prices rising to all-time highs and environmental programs are the reason why consumers are complaining about driving their automobiles today. The primary use for gasoline is in automobiles and light trucks. Fuel produced all year round‚ and is delivered from oil refineries through pipelines to a massive distribution chain serving 167‚000 retail stations throughout the United States ("EIA Brochures"‚ 2004). Refineries produce millions of barrels of gas a day;

Bio-fuels Menno van Amen TV4E 13-06-2013 The production of bio-fuels has become a controversial topic as the 21st century progresses. Lately the production of biofuels has been discussed quiet frequently and many people have started focusing on the question if the production of biofuels actually is environmental friendly. Firstly‚ what is a biofuel? Biofuels refer to any solid‚ liquid or gas fuel that has been gotten from biomass. They produce biofuels by growing plants‚ growing sugar

Alternative fuels‚ or at least the concept of it‚ has been around since the early days of the automobile. Alternative fuels such as biodiesel‚ ethanol and methanol‚ have been produced and used on a small scale for decades. They are now being rediscovered due to the rising cost of oil and the instability of world politics. The discovery of these fuels changed the face of the planet‚ but since day one people have looked for other fuels that improved over the course of history. Alternative fuel vehicles
