  • Petroleum products are everywhere around us. They appear in visible forms, such as gasoline, diesel, kerosene, and aircraft fuels, and in less visible forms over the entire spectrum of industry, such as automobile lubricants, greases, carbon black for truck tires, bitumen for road building, the waterproofing in house roofs, feedstock for petrochemicals, synthetic fibers, and plastics. Petroleum feedstock is used in the manufacture of white mineral oils in eye ointment, hair oils, cosmetics, petroleum solvents, and pest control sprays....

  • Diesel engines, also known as CI engines, possess a wide field of applications as energy converters because of their higher efficiency. However, diesel engines are a major source of NOX and particulate matter (PM) emissions. Because of its importance, five chapters in this book have been devoted to the formulation and control of these pollutants. The world is currently experiencing an oil crisis. Gaseous fuels like natural gas, pure hydrogen gas, biomass-based and coke-based syngas can be considered as alternative fuels for diesel engines.

  • When will the oil run out? Various estimates put this anywhere from 20 years from now to more than a century in the future. The shortfall in energy might eventually be made up by developments in nuclear fusion, fuel cells, and solar technologies, but what can substitute for gasoline and diesel in all the internal combustion enginepowered vehicles that will continue to be built worldwide until then? And what will stand in for petrochemicals as sources of building blocks for the extensive range of “synthetics” that became indispensable during the twentieth century?...

  • The recent fuel cell (FC) development worldwide has always been accompanied by a number of studies and projects investigating the applications of FCs onboard ships. Almost all possible FC types and different fuels such as hydrogen, natural gas (liquefied or pressurized), liquefied pressurized gas (LPG), methanol, and maritime diesel have been considered. These applications of FCs are still mainly focused on onboard power generation (OPU) and propulsion.

  • No wonder it's so hard to lose weight -- our bodies are designed to keep weight on at all costs; it's a matter of survival. It's embedded in our DNA. Our diet has changed dramatically over the past ten thousand years, but our genetic blueprint has not -- our bodies are not designed to process the types of food we are fed today. It's like putting diesel fuel into a regular car -- it just won't work. And making matters worse is the fact that diets don't work either: less than 6 percent of weight-loss attempts succeed. The average person...

  • The planned biofuels increase will be a boon for the farm sector, which will see production of biofuel crops jump from today's 320,000 hectares to more than 1.2 million hectares by 2007. Three-quarters of current biofuel production is rapeseed-based "diester," a vegetable oil-sourced diesel fuel known as "bio-diesel" in other parts of Europe, while the remainder is comprised of ethanol sourced from a variety of crops, including beetroot, sugar cane, corn, potato, and wheat, according to government data.
