Bacteria batteries for mobile phones
Two different articles today on alternative technology for batteries.
Bacteria batteries for mobile phones
Mobile telephones and other portable electronic devices could one day be powered with the help of bacteria, thanks to an advance in energy technology, reportsFuel Cell Works.
"A team at the John Innes Centre, Norwich, reports in the journal Nature that it has built the active part of a bacterial enzyme that works like a miniature hydrogen fuel cell."
A new power source
Developments are under way that could wipe batteries off the face of the Earth. Researchers at the Oregon Nanoscience and Microtechnologies Institute (ONAMI), say they have made significant breakthroughs in a power source that essentially turns 20 pounds of batteries into 8 ounces of fuel the size of a cigarette lighter, reports The Washington Times.
"The immediate aim is to use nanotechnology — science on the tiniest scale — to replace cumbersome military batteries and eventually power everything "from cell phones up to systems that run a tank," said Kevin Drost, ONAMI's co-director of research. "
