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.
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 ...
Researcher manipulates micro-scale phenomena to optimize energy conversion devices
You can quickly run out of fingers and toes counting the many ways we waste energy. Take our sewage systems, for example: The energetic content of wastewater is about 10 times the amount of energy it takes to process it. ...
Microbial hair -- it's electric: Specialized bacterial filaments shown to conduct electricity
(PhysOrg.com) -- Some bacteria grow electrical hair that lets them link up in big biological circuits, according to a University of Southern California biophysicist and his collaborators.
Bacteria use hydrogen, carbon dioxide to produce electricity
Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon. Researchers at the University of Massachusetts, ...
