Wires turn salt water into freshwater
Robots may receive urine-powered artificial 'hearts'
Researchers develop unique waste cleanup for rural areas
Washington State University researchers have developed a unique method to use microbes buried in pond sediment to power waste cleanup in rural areas.
Solar-induced hybrid fuel cell produces electricity directly from biomass
Although low temperature fuel cells powered by methanol or hydrogen have been well studied, existing low temperature fuel cell technologies cannot directly use biomass as a fuel because of the lack of an ...
Breakthrough in race to create 'bio-batteries'
(Phys.org) —Scientists at the University of East Anglia have made an important breakthrough in the quest to generate clean electricity from bacteria.
Hugging hemes help electrons hop
(Phys.org) —Researchers simulating how certain bacteria run electrical current through tiny molecular wires have discovered a secret Nature uses for electron travel. The results are key to understanding ...
Tiny power generator runs on spit
Saliva-powered micro-sized microbial fuel cells can produce minute amounts of energy sufficient to run on-chip applications, according to an international team of engineers.
Boldly illuminating biology's 'dark matter'
Is space really the final frontier, or are the greatest mysteries closer to home? In cosmology, dark matter is said to account for the majority of mass in the universe, however its presence is inferred by ...
Last universal common ancestor more complex than previously thought
Scientists call it LUCA, the Last Universal Common Ancestor, but they don't know much about this great-grandparent of all living things. Many believe LUCA was little more than a crude assemblage of molecular parts, a chemical ...
Unique salt allows energy production to move inland
Production of energy from the difference between salt water and fresh water is most convenient near the oceans, but now, using an ammonium bicarbonate salt solution, Penn State researchers can combine bacterial ...
Saltwater boosts microbial electrolysis cells to cleanly produce hydrogen
A grain of salt or two may be all that microbial electrolysis cells need to produce hydrogen from wastewater or organic byproducts, without adding carbon dioxide to the atmosphere or using grid electricity, ...
Using microbes to generate electricity
Using bacteria to generate energy is a signifiant step closer following a breakthrough discovery by scientists at the University of East Anglia.
Artificial heart to pump human waste into future robots
A new device capable of pumping human waste into the "engine room" of a self-sustaining robot has been created by a group of researchers from Bristol.
A shocking diet: Researchers describe microbe that 'eats' electricity
A team of Harvard researchers showed that the commonly found bacterium Rhodopseudomonas palustris can use natural conductivity to pull electrons from minerals located remotely in soil and sediment while remaining at the su ...
