Edison had a better solution than Westinghouse?

In the July 26, 2007 edition of The Economist is an article about alternatively fueled power plants. Wind power apparently is better suited to a DC power grid, rather than the current AC grid. In the late 19th century, the battle between Edison's direct current power lines and Westinghouse's alternating current lines. 

DC lines send electrons flying from the negative terminal to the positive terminal (thank Benjamin Franklin for this somewhat backwards intuition).  AC essentially flips the terminals back and forth, so electrons flow back and forth--this is where the 120Hz comes into play.  Westinghouse's AC lines won over Edison, because it was considered easier to transfer power over longer distances via AC.  However, the article in The Economist mentions that DC lines actually outperform AC lines in terms of how far power may be transfer.  In addition, the lines may be placed closer to the ground without power degradation.  It would interesting to see if DC lines actually replace the well-established AC lines in the coming years.
