The search for fuels without contaminant components

To convert a gaseous fuel into a clean liquid one is the target of the research project being undertaken by the School of Industrial Engineering and Telecommunications Engineers of Bilbao in the Basque Country. It involves, in the final analysis, obtaining fuels which do not have contaminant components, i.e. sulphur, nitrogen or aromatic components.

Participating in this project, financed by the MARCO programme of the European Union, are nine groups from different European countries, under t

Conserving hydrocarbons would save $438 billion

Just as low-carbohydrate diets are trimming the American waistline, more judicious use of hydrocarbon-based fossil fuels would reduce U.S. energy consumption by 33 percent and save consumers $438 billion a year by 2014, according to an analysis by Cornell University ecologists.

David Pimentel, Cornell professor of ecology, and 11 student ecologists found the most fat for trimming — with the best potential for major energy savings — in the transportation, residential heating and cooling, i

From fryer to fuel tank, U-M students make a case for waste elimination and energy recovery

University of Michigan engineering students have discovered a redeeming quality in junk food: waste grease produced in campus cafeterias that can be used to make biodiesel fuel for U-M buses.

During a term project for a course in environmental sustainability, a four-student team led by Lisa Colosi and Andres Clarens concluded and demonstrated that it is economically and technically feasible to harvest the 10,700 gallons of waste grease produced in the 10 campus dining halls to make an effec

Converting waste heat into electricity

“Waste heat” might not be such a waste after all. The excess heat produced in everything from microelectronics to large ship engines is generally thought of as a problem for engineers to solve. But a new leap in semiconductor technology funded by the Office of Naval Research could put that troublesome heat to good use.

Dr. Mihal Gross of ONR’s physical sciences division explains, “With this class of semiconductors, when you have a

Mini-batteries for mobile phones

CIDETEC is working on a project the aim of which is to carry out a direct assessment of the technology of fuel cells for “mini” applications which have between 1 and 10 watt power requirements – such as for mobile phone or PDA chargers or for remote signalling, etc. to this end, a series of technologies are being developed in order to obtain a house technology mini fuel cells, including the design and enhancement of EMAs (electrode-membrane assemblies), of structural elements (current collectors, sh

Europe could ride the wave of Ocean Energy

Up to 20 million homes in Europe could be powered by clean renewable energy from the sea, according to ocean energy expert Teresa Pontes of Portugal, who was speaking at the EurOCEAN marine science and policy event in Galway today (12th May). She estimated that, by harnessing energy from waves and marine currents, Europe would produce around 200 TerraWatt (200 million megawatt) hours per year of electrical power.

“The oceans contain a huge energy resource with different origins,” said Ms. Te
