Fuels are any materials that store potential energy in forms that can be practicably released and used as heat energy. The concept originally applied solely to those materials storing energy in the form of chemical energy that could be released through combustion, but the concept has since been also applied to other sources of heat energy such as nuclear energy (via nuclear fission or nuclear fusion), as well as releases of chemical energy released through non-combustion oxidation (such as in cellular biology or in fuel cells).
I was writing a while ago that major biofuel production is not really that far away and the good news is things seem to be moving in that direction. The importance of biofuels has been underlined as a possible solution to fight the crisis, but the big problem was that creating such alternative fuels required [...]
This month, two independent teams have announced that they have succesfully converted sugar-potentially derived waste from agriculture and non-food plants into gasoline, diesel, jet fuel and other chemical substances of high importance. Randy Cortright, a chemical engineer at Virent Energy Systems of Madison, Wisc. announced that carbohydrates and sugars can be processed into a number [...]
