Most of our energy requirements today are met by fossil fuels. These fuels were created in the interior of the Earth, when rotting ancient animal and plant remains got pressurized by the crust. As we use more and more of these fuels, it becomes harder and harder to mine/drill and transport and refine them for use. Some better way has to be found to meet our growing energy needs, and bio-fuel is one of them.

Fuel Cycle (Courtesy: PhysOrg)University of Wisconsin researchers have discovered a new way to make a diesel-like liquid fuel from carbohydrates commonly found in plants:). Published in the journal Science, Steenbock Professor James Dumesic and colleagues detail a four-phase catalytic reactor in which corn and other biomass-derived carbohydrates can be converted to sulfur-free liquid alkanes resulting in an ideal additive for diesel transportation fuel.
The process is very efficient, as the fuel contains 90% of the energy found in the carbohydrate and hydrogen feed. This process has twice the potential to create Ethanol (Ethyl Alcohol) than corn. Corn produces 1.1 units of energy for every unit of energy consumed. This process creates 2.2 units of energy for every unit of energy consumed in energy production:):).
The process works with a range of carbohydrates. As About 75% of the dry weight plants and trees is carbohydrates, a wider range of plants can be used to make bio-fuel.
