Hydrogen gas by combining electron- generating bacteria & small electrical charge...
Pennsylvania State University researchers last week announced that they have developed a method of producing hydrogen gas by combining electron-generating bacteria, acetic acid and less than .2 volt source in a microbial fuel cell.

I first heard about this last week on NPR's Talk of the Nation. Here is NPR link - http://www.npr.org/templates/story/story.php?storyId=16343702&sc=emaf
The researcher who led the project Bruce Logan, the director of the Hydrogen Energy Center there said last week on the show that this was actually a relatively simple process.
He claims 90 percent efficiency. Also claimed is that the process produces 288 per cent more energy in hydrogen than the electrical energy that is added to the process.
I would love to build one small scale and combine it with solar panels. Or maybe try to generate some hydrogen and try using it as a fuel supplement for my car using something like this - http://www.hydrogen-fuel.ca/ . Anyone willing to tackle this one?
