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
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 ONRs physical sciences division explains, “With this class of semiconductors, when you have a
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
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
Like the signals it emits, the radio may soon disappear from sight.
University of Florida electrical engineers have installed a radio antenna less than one-tenth of an inch long on a computer chip and demonstrated that it can send and receive signals across a room. The achievement is another step in the teams continuing efforts to build an “ultrasmall radio chip” – a transceiver, processor and battery all placed on a chip not much larger than a pinhead – and one that could one
