James wants to know about these.
Ken too.
VERY high capacity batteries.
___________

The interview at the end is worth looking at for it's "this is how 
science/engineering happens" lessons.
In this case the battery very nearly didn't.

Flow batteries are electrically like conventional batteries but store 
energy in liquid "plates" which is able to be pumped out into storage 
when charged. Very large batteries in the 100's of kW and several MWh 
range are being built.

Flow batteries are not new BUT the Vanadium Redox battery uses 
identical fluids in both halves and uses the multiple oxidation levels 
of vanadium to form both negative and positive "plates". Leakage 
between halves is equivalent to self discharge rather than 
contamination as in other flow cells.

Invented / patented by Sydney university in 1980s. A large trial unit 
is being used with a windpower system on King island in bass Strait.
