And this thing ..
…looks like a bit like a giant cocktail shaker from that angle ?
It also looks a bit small for the space?
But it seems they hope to add more after the ‘initial’ unit proves it produce turn out the right kind of stuff….
.. “ The vanadium electrolyte plant will initially be able to produce enough electrolyte per annum to fill VRFBs that can store up to 33MWh of energy.
For comparison, a single Tesla Powerwall stores 13.5 kWh of energy2, with the electrolyte plant
producing the equivalent energy storage capacity of 2,444 Powerwalls per year…”
….And I wonder who they will invite to the official opening?
The boss of Horizon?
A few ministers?
Lots and lots of journalists to enjoy some rainbow-coloured drinks and then write lavish media reports?
Thanks drsking for that diverting update 
cheers
