Battery Tips

7. Horizontal drilling technology

11,000 feet underground of the United States (about 3352 meters) shale, a few trillion cubic feet of natural gas are hidden there. The gas flow slow as to the unusually dense rock, most of the natural gas could not drill with ordinary drill. The solution is: first, vertical down drilling rock and then gradually to 90 ° horizontal bends, through the shale gas reservoirs. This is not a new idea, but at a higher energy prices and more advanced technology to promote, the energy companies suddenly began to focus on the technology. In 2008, the United States, Chesapeake Energy’s shale gas field in southern Hailavegas deployment of 14 horizontal drilling. According to their estimates the number of horizontal drilling is expected to end in 2010 to 40.

8. Kinetic hydropower

Conventional hydroelectric dam to be built, but construction of dams is often a large-scale engineering projects, will change the local landscape and ecosystems. Kinetic energy of the environmental impact of hydropower is a smaller solution, using the natural flow of rivers and tides drive underwater turbines. Since 2006, the United States has been the company Verdant Power East River in New York (Roosevelt Island, located in the east) test six underwater turbines in order to prove that this technology has potential for development. The company hopes to receive approval in 2010, in the East River deployment of 30 large underwater turbines, for the United States 1 trillion watts of electricity transmission grid. Other similar projects worldwide will soon complete testing and begin fully operational, including the largest in the world, Canada Bay of Fundy tidal range of 3 to install underwater turbines.
