offlineimap: "OfflineIMAP is a tool to simplify your e-mail reading. With OfflineIMAP, you can read the same mailbox from mul- tiple computers. You get a current copy of your messages on each computer, and changes you make one place will be visible on all other systems."  I have read that it is a good tool for synchronizing with IMAP server-to-server, or as a platform for agents.  6:57:29 PM  permalink  

New Catalyst For Renewable Hydrogen: Significant improvement in biomass conversion using cheaper materials at lower temperatures in simpler liquid process:  "Scientists have developed a hydrogen-making catalyst that uses cheaper materials and yields fewer contaminants than do current processes, while extracting the element from common renewable plant sources. Further, the new catalyst lies at the heart of a chemical process the authors say is a significant advance in producing alternate fuels from domestic sources.

In the June 27 issue of the journal Science, James Dumesic, John Shabaker and George Huber, of the University of Wisconsin at Madison, report developing the catalyst from nickel, tin and aluminum and using it in a process called aqueous-phase reforming (APR), which converts plant byproducts to hydrogen. The process performs as well as current methods that use precious metals such as platinum, yet runs at lower temperatures and is much cleaner."  Photos at NSF site. They say it can be productive at small scale.  Virent Energy Systems has been formed to commercialize the technology.  This Conference Paper has some technical details and contact info. PDF papers provide more technical details.
