Researchers from Penn State University claim that they have developed a prototype device that can use wastewater to create electricity, essentially transforming treatment stations into power plans. Lead researcher and engineering professor Bruce E. Logan and his colleagues have combined microbial fuel cells (which can use wastewater and naturally occurring bacteria to generate electricity) and reverse electrodialysis (which creates power from the differences in salt concentration between...

  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, according to Penn State engineers. "This system could produce hydrogen anyplace that there is wastewater near sea water," said Bruce E. Logan, Kappe Professor of Environmental Engineering. "It uses no grid electricity and is completely carbon neutral. It is an inexhaustible...

The first demonstration of a renewable method for hydrogen production from wastewater using a microbial electrolysis system is underway at the Napa Wine Company in Oakville. The refrigerator-sized hydrogen generator will take winery wastewater, and using bacteria and a small amount of electrical energy, convert the organic material into hydrogen, according to a Penn State environmental engineer. "This is a demonstration to prove we can continuously generate renewable hydrogen and to study the...

A tiny microbe can take electricity and directly convert carbon dioxide and water to methane, producing a portable energy source with a potentially neutral carbon footprint, according to a team of Penn State engineers. "We were studying making hydrogen in microbial electrolysis cells and we kept getting all this methane," said Bruce E. Logan, Kappe Professor of Environmental Engineering, Penn State. "We may now understand why." Methanogenic microorganisms do produce methane in marshes and...

Platinum is highly desired in jewelry and as a catalyst, but in both cases it is expensive. Now, Penn State researchers have found a way to replace the platinum catalyst in their hydrogen generating microbial electrolysis cells with stainless steel brushes without losing efficiency."Stainless steel brush cathodes can produce hydrogen at rates and efficiencies similar to those we have achieved with platinum-catalyzed carbon cloth," says Bruce E. Logan, Kappe professor of environmental...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
