car runs on salt water

[arcosine]

This car claims to run on salt water. It is not sea water, I suspect is is a Bromide salt. The energy storage is a cross between a battery and a fuel cell, th electrolytes are stored in separate tanks and pumped across a membrane that separates the two. This is where the ion exchange happens. The electrolytes can be changed out, restoring a full charge in minutes, unlike a conventional lithium battery that takes hours to charge up. NASA developed the technology in the 1970s. The super car has ultra capacitors to store charges for peak acceleration demands.

A 4 seater, 912 hp supercar, that goes 0-60 in about 2.8 seconds, and runs on saltwater. Hmmm... It is a awesome design I'd love to see it produced but I can't bring myself to believe that everything stated about it is true.

Well, that diagram above shows two electrolyte tanks, one that starts out with a vanadium salt in the +2 oxidation state that gets oxidized to the +3 oxidation state as power is produced, and the other tank has a vanadium salt that starts in the +5 oxidation state and gets reduced to the +4 oxidation state. Actually, they don't have to be salts but it is most likely they are. So in the loosest sense, both tanks contain "salt water" because they contain water with a salt dissolved in it, but it isn't sea water and it isn't sodium chloride which is what everyone thinks of when you say salt water. I'm sure some chemist (don't you hate those guys, um, us :-)) said the tanks contained a salt solution and some advertising flak took that to mean sea water.

Think of this as a primary battery, non-rechargeable, like an alkaline cell. As power is produced the electrolytes are consumed, but instead of changing out the entire cell they just pump in fresh electrolyte. Since they will get cooling from the flow as well, they probably get a nice boost in current density before meltdown, too. However, to regenerate the electrolytes they have to take them out and go do some other processing, probably with different electrodes for better efficiency or maybe even adding a different reagent to do the oxidation and/or reduction that they can then remove and regenerate, so you can't just recharge in place.

Reminds me of this this:
Salt Water Fuel Cell Car - Robotikits Direct

It's a toy car that "runs on salt water" that teaches children about clean energy! Well, it runs on a battery that uses salt water. (And just ignore the magnesium sheets that keep getting used up as you play with it)

Sounds like something for the unicorn central.

Its green so long as you ignore the metal it consumes, where that metal came from and how much energy it took to make it.

Beautiful and artistic design! I would love to have a car like that. Who cares what it's powered by...?
