Does anyone recognise this TEDx talk about a new (flow?) battery ?

I'd like to thank whoever posted this link on a new flow (?) battery made in the states.

I posted the link in this thread here: http://forum.solar-electric.com/showthread.php?19079-Alternative-to-Lead-Acid-Batteries

It's actually not a flow battery, but a sodium ion battery in aqueous solution with Carbon and Manganese Dioxide as electrodes. The company based in the Pittsburgh area, are set to begin manufacturing batteries later this year. Apparently, the batteries are as efficient as the lead acid battery, will be cost competitive, but have a much greater cycle life with no concern about leaving them in a partial state of charge for long periods of time, use no toxic materials, and operate with no risk of fire or explosion hazards.

Thanks again Northerner. I followed a bunch of links and found out a bit more about them. Still not in production, though there was one posting that they shipped one lot for testing to Oz... no follow up though.

you might like this one from Oz, http://redflow.com/ I think it was the 510 model I thought was suited to home use, I see that they have more new info I will have to read ...

Looks like the battery from Reflow will be costly. Each battery has built in control electronics and sensors. I see the military is interested in them. http://redflow.com/redflow-products/oem-zbm/

Batteries from Aquion should be cost competitive with current storage (ie lead acid). If what they claim is true, they will be a real bargain, as cycle life is much higher. Essentially a set of batteries could last a lifetime, with little or no maintenance, and no concern about leaving them at a partial state of charge for extended periods. Almost sounds too good to be true!

somewhere in their literature they reference cost competitive with various batteries technologies. That is what got me interested . It is on page 13 of this doc
