More flexible method floated to produce biofuels, electricity--Purdue News (10/14/08)

WEST LAFAYETTE, Ind. - Researchers are proposing a new "flexible" approach to producing alternative fuels, hydrogen and electricity from municipal solid wastes, agricultural wastes, forest residues and sewage sludge that could supply up to 20 percent of transportation fuels in the United States annually.
The method offers a potential solution to problems that might be created by increasing production of ethanol with conventional methods, which use corn grain as a feedstock. Boosting ethanol production with conventional methods would require additional crops and heavy fertilizer use, increasing runoff into waterways and threatening ecosystems.
The new concept, however, which Purdue researchers call a flexible carbon-to-liquid fuel process, would require no additional crops and use primarily wastes as the feedstock, said Fu Zhao, a Purdue assistant professor of mechanical engineering.

Groups of high schoolers eagerly lined up Tuesday morning at Purdue University to test how well their handcrafted wind turbines would perform when stacked against the power of four fans. The kids were competing to create a turbine that would generate the most energy as a part of a challenge for the Duke Energy Academy at Purdue. The annual academy, now in its fifth year, brings in U.S. high school students to learn about renewable energy with hopes they'll be inspired to pursue careers in science, technology, engineering and mathematics fields and solve energy challenges. "We want these students to be the leaders of tomorrow," said Pankaj Sharma, managing director of the Purdue Energy Center and Global Sustainability Institute. The academy lasts throughout the week and is hosting 52 students and 27 teachers from mainly Indiana schools, though about 20 percent come from outside states, said Tolu Omotoso, a civil engineering graduate student and coordinator for the academy.Read Full Story
