Talk:Reversed electrodialysis

RED as a process for producing of renewable energy

Hydrogen production from inexhaustible supplies of fresh and salt water using microbial reverse-electrodialysis electrolysis cells, Younggy Kim and Bruce E. Logan, PNAS 2011 : 1106335108v1-6. http://www.pnas.org/content/early/2011/09/12/1106335108.abstract This is a rather prestigious print publication to be approving such a bold claim, or so it seems to me. Anyhow, well covered in the popular press, popsci, discover, tv sites The abstract doesn't make it clear but Science Daily indicates that the RED potential feeds an electrolysis cell to produce H2. http://www.sciencedaily.com/releases/2011/09/110919151317.htm

Renewable energy by reverse electrodialysis, M. Turek, B. Bandura, Desalination, Volume 205, Issues 1-3, 5 February 2007, Pages 67-74 http://www.sciencedirect.com/science/article/pii/S0011916406013622 Full text seems avail at the mo at http://www.desline.com/articoli/8124.pdf This seems to report on investigation of feasibility of producing useful electricity, with review of prior developments.

So here's some language I suggest for a new subsection after Testing. RED as a process for producing renewable energy. Desalination researchers have also explored the possibility of energy-efficient use of RED to produce electricity and H2 gas for use as fuel. The interaction of brine and freshwater across certain membrane materials can produce useful amounts of electricity, though not necessarily efficiently --ref Turek and Bandura here--, and typically depending on costly precious metals for electrode materials. Some researchers have reported high efficiency with use of nonprecious electrode materials --ref Kim and Logan here-- when the RED reaction is enhanced by additional electrical potential that arises from degradation of bacteria called exoelectrogens, which also play roles in fuel-cell research. During 2011 researchers from Penn State issued the remarkable claim that such a RED process has the potential to supply "inexhaustible" renewable energy from common materials such as seawater, river water, and organic matter.

Hope nobody minds this Talk comment is formatted the way it is...I've been confused about previewing footnotes on Talk pages. munge (talk) 05:21, 23 September 2011 (UTC)[reply]

Its not 'Reversed'

It's 'Reverse electrodialysis', as evidenced by the spellings of most if not all of the scholarly articles on the web.
