"There is real potential here that the vanadium may become very valuable in the next few years if they can find a way to make it smaller. Imagine if they can find a chemically reactive agent that would allow them to shrink a vanadium battery to the size of batteries used in Hybrid cars etc."

In the interim, don't forget there is an alleged application prior to being able to miniaturize it, whereby it can be used industrially where size is not as critical, that being on the grid and other similar applications where large amounts of "hydro" needs to be stored, not just for electronics and auto potential. The issue is the "infinite" times it can be charged, the speed with which it can be charged and the low heat involved. Diminished space will come.
