Dear friends: terra preta is fascinating in part because it involves so many disciplines. My viewpoint is that of a fuel scientist/chemical engineer.

My laboratory produces well-characterized charcoals for a wide variety of research endeavors, including carbon fuel cell studies, metallurgical charcoal applications, activated carbon production, and terra preta research (with my colleagues Dr. Goro Uehara, Dr. Jonathan Deenik, and Tai McClellan in the University of Hawaiibridge media | NIKE AIR HUARACHE
