Believe it or not: liquid batteries make energy storage real and affordable

The headline from the Massachusetts Institute of Technology (MIT) says, "It's Official: Wind Energy Can Be Stored Cheaply"' but gosh--cheap just sounds  Energy storage is more than just a cool advancement in technology, it is the Holy Grail. Grid level storage will make alternative and renewable energy available to the mass market with regularity and at a truly affordable rate. It's energy storage that will make harnessing temperamental energy sources like wind and solar plausible as a solution to our world energy needs.  It's energy storage that is the missing link.  To include cheap in the sentence seems somewhat demeaning ( although it is a press release from MIT and if Good Will Hunting taught me anything it's that those MIT guys know their stuff!).

Turns out one MIT guy in particular knows his stuff about grid level electrical storage and how to make it cost effective. Professor Donald Sadoway has developed the liquid metal battery; a device as he says, invented to the price point of the electric market.  Professor Sadoway's TED talk about his liquid metal battery is entertaining (colored chalk!) and actually makes simple sense of something that should be much more complicated.  

Donald Sadoway: solving energy's biggest challenge, like a boss.
