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.

Alternatives to Gasoline in Vehicles One of the most pressing issues in today’s society both climatically and economically is the use of gasoline and fossil fuels in our vehicles. Ever since the creation of the automobile in the early 1900s gasoline has become a commodity that helps the global economy tremendously. However‚ after over one hundred years of the use the resource has come to be scarcer‚ and all of the greenhouse gases and pollution that were released have helped set in motion the

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

Great Impact of Rising Fuel Price Fuel is another transportation system component. Rising of fuel price is one of the major issues facing the transportation industry in Malaysia. Fuel may be gasoline‚ natural gas‚ diesel fuel‚ ethanol‚ methanol‚ coal‚ etc. The costs and efficiency of transportation fuels are considerable interest. (Joseph Sussman; Introduction to Transportation Systems; Transportation System Components; 2000). Fuel price volatility along with overall price increases has been an

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 dinosaur but‚ scientists have many ways of learning about them. One important way is by studying fossils. Fossils give scientists a vast amount of information about ancient animal and plant life which have become extinct. They also helped them in finding out how long ago the animal or plant lived. As animals and plants die over the years they get covered

least 6 million years. A. From Ape To Man Fossils from several different early australopith species that lived between 4 million and 2 million years ago clearly show a variety of adaptations that mark the transition from ape to human. The very early period of this transition‚ prior to 4 million years ago‚ remains poorly documented in the fossil record‚ but those fossils that do exist show the most primitive combinations of ape and human features. Fossils reveal much about the physical build and activities

Fossils are found on Mount Everest because the mountains were once the sea bed before rising. The types of fossils in Mount Everest are marine fossils. Marine fossils are sea animals‚ plants‚ or sea shells basically anything in the water that are now fossils. The types of fossils indicate the environment that these fossils were found on the ocean floor‚ meaning at one point in time‚ the seas cover the land(Geology of the Mount Everest). The marine fossils end up on Mount Everest by continental drift

There has also been a significant increase in the use of fossil fuels. This year alone‚ gas increased to a whopping $3.21 average in the state of Alabama alone (www.gasbuddy.com). California had the biggest increase going above the $5.00 mark (www.gasbuddy.com). As long as our fossil fuel supplies continue to vanish‚ the price

This increased content of carbon dioxide increases the warmth of our planet and is the main cause of the so called “Global Warming Effect.” One answer to global warming is to replace current technologies with alternatives that have comparable or better performance‚ but do not emit

Hydrogen Fuel Cells There are many reasons to look for new cleaner forms of energy. Fossil fuels‚ being non-renewable‚ will eventually run out. Pollution from burning fossil fuels destroys our environment. Hydrogen fuel cells could be used many places where fossil fuels are currently being used. Using hydrogen as a form of energy can not only reduce our dependence on imported oil‚ but also benefit the environment by reducing emissions of greenhouse gases and pollutants that affect our air quality
