BBC News: Molten metal batteries for the grid

[Frank Gentges]

I was unaware of this system in Bath county right here in Virginia. 
There is a nice video at:

I was impressed by the transport of the part along the mountain roads 
all the way to York, PA for refurbishment.  That is quite a trailer.

I also wonder what the liquid metal battery would look like that could 
replace this setup.  All that hot metal could be a problem.
