So they are pumped into the system in suspension and then settle into two layers? I'm having visions of the battery liquid sloshing around while driving. This seems neat, though I think often academics solve one problem in a lab and then imagine a whole string of other problems will easily be solved to get their product to market. The guy said the biggest problem is "man power". I'm skeptical of this claim. They haven't built anything other than a table top demo -- I'd of liked to see them build a unit that could power something significant. Stick one in a golf cart at least. But neat and inspiring nonetheless.
