This video shares combination of innovative drilling and well completion techniques which have revolutionized the gas industry, opening up massive new sources of shale gas production in North America.

Watch this video to discover how or what is horizontal drilling combined with hydraulic fracturing. 

Donald Sadoway is working on a battery miracle -- an inexpensive, incredibly efficient, three-layered battery using “liquid metal." This technological leap will dramatically change the electricity industry. The biggest assumption of non storable will be outdated.

Donald presented his project on TED which also can be seen here.
