They must have stolen the batteries from this.

Anyone know how it actually works?

Of course it's all on Wikipedia. http://en.wikipedia.org/wiki/Flow_battery

I would think that the idea is that the two fluids are pumped past a couple of electrodes with an electric motor between then and the charge flows from one electrode to the other through the motor, thus powering the car and nuetralising the charged fluids. To charge it up the fluids are recharged and, when power is needed, pumped back to their original storage.

I saw a Tesla electric car at Ecobuild. Enormous thing it was and built from steel so must weigh a tonne or two. I think that it comes within the category of EcoBling although some might like to put it in Ecobilge.

The concept of a flow battery is interesting but this car is vapourware.

No-one has seen it move and the technical specs have the few chemists I have seen comment on line spitting coffee.

The devil is in the detail and there is ZERO information about

1. The chemistry involved
2. The membrane (or otherwise) in the fuel cell.

The quoted energy density of the chemicals does not match any published research
The power output implied by the acceleration figure is several times the nominal output of the fuel cell
Most of the car would be one giant , heavy, fuel tank for the electrolytes.

No-one has demonstrated a fuel cell that is this powerful and reliable and small and light and cheap enough to fit into a car, even a supercar.
