"This year, Copenhagen&amp;#039;s annual Christmas tree will light up with the help of Danish citizens&amp;#039; aerobic efforts. The energy produced by the riders of 15 bicycles in Copenhagen&amp;#039;s City Hall Square will light up the 700 LED bulbs that adorn the 17-meter-tall evergreen."^^<http://www.w3.org/2001/XMLSchema#string>
