A small start up company is attempting to build cheaper batteries to support micro-grids, the kind of small scale electric grid the can combine electricity from multiple sources.  To date, such micro-grids are used only for remote villages, and are limited by the cost and short life of the batteries.  This company thinks it can make batteries for about the same cost of conventional, but with a much longer life. 

More power (sic) to them!

And notice how this pioneering effort is private, and requires no public money, unlike dirty crony deals like Solyndra and their brethern.

I for one would consider organizing a micro-grid like this for my neighborhood, as long as it could provide even a bit cheaper power.  Given the size of my power bill lately, I think that it couldn't be to hard to beat the power company's price.

Below one of the owners demonstrates how the batteries can be stacked to build the exact size needed to store the electricity.
