Researchers decode genetics of rare photosynthetic bacterium

pkrecker — Thu, 14 Feb 2008 14:02:11 -0700

Researchers have cracked the genetic code of a bacterium that harvests far-red light by making a rare form of chlorophyll (chlorophyll d). The bacterium, Acaryochloris marina, uses light from a part of the spectrum that few other organisms can use. Understanding how it works could help drive advances in agriculture and bioenergy. --by Skip Derra

Bacteria and sunlight make clean, green hydrogen

Microbial fuel cell technology uses the tiniest organisms on the planet--bacteria--as a viable option to make electricity. By linking bacterial metabolism directly with electricity production, the MFC eliminates the extra steps necessary in other fuel cell technologies. --by Joe Caspermeyer

Easy energy with power-generating backpack

pkrecker — Mon, 31 Dec 2007 08:00:00 -0700

An ASU researcher has designed a special backpack that can produce an electrical charge through the force of the motion of its wearer. This "energy harvesting" can generate the power to charge batteries or run small electronic devices such as cell phones, iPods or flashlights. --by Joe Kullman

Fuels of Green
