- 'Juiced-up' battery fueled by sugar could power small portable electronics
03-25-2007 · EurekAlert!
Juicing up your cell phone or iPod may take on a whole new meaning in the future. Researchers at Saint Louis University in Missouri have developed a fuel cell that runs on virtually any sugar source -- including soft drinks -- and has the potential to operate three to four times longer on a single charge than conventional batteries, they say. The research will be presented in March at the American Chemical Society national meeting in Chicago.

- New homes rise from rubbish
04-02-2007 · EurekAlert!
Imagine if you could turn old rubbish into new houses. That's exactly what civil engineer Dr. John Forth in the School of Engineering wants to achieve with the invention of a building block made almost entirely of recycled glass, metal slag, sewage sludge, incinerator ash and pulverised fuel ash from power stations.

- Two bacteria better than one in cellulose-fed fuel cell
07-27-2007 · EurekAlert!
No currently known bacteria that allow termites and cows to digest cellulose, can power a microbial fuel cell and those bacteria that can produce electrical current cannot eat cellulose. But careful pairing of bacteria can create a fuel cell that consumes cellulose and produces electricity, according to a team of Penn State researchers.

- Study: cow-powered fuel cells grow smaller, mightier
08-21-2007 · EurekAlert!
Cows could one day help to meet the rise in demand for alternative energy sources, say Ohio State University researchers that used microbe-rich fluid from a cow to generate electricity in a small fuel cell. This new microbial fuel cell is a redesign of a larger model that the researchers created a few years ago. The new cell is a quarter of the size of the original model, yet can produce about three times the power.

- Step on the gas -- New fuel cell design adds control, reduces complexity
01-16-2007 · EurekAlert!
When Princeton University engineers want to increase the power output of their new fuel cell, they just give it a little more gas -- hydrogen gas, to be exact. This simple control mechanism, which varies the flow of hydrogen fuel to control the power generated, was previously thought impossible and is a potentially major development in fuel cell technology.

- Fuel cells gearing up to power auto industry
10-30-2007 · EurekAlert!
The average price for all types of gasoline is holding steady around $2.95 per gallon nationwide, but the pain at the pump might be short-lived as research from the University of Houston may eliminate one of the biggest hurdles to the wide-scale production of fuel cell-powered vehicles.
