I like wind power and zip lines so why not combine the two? It seems silly to have structures that catch the wind but serve no other purpose. A few modifications could provide a network of zip lines between wind turbines akin to ski lift technology using pulleys. Small electric motors winch people up to a launch platform. They hook on to the line and their body mass moves the line which is coupled to small generators at each end. Depending on the lie of the land and height of the tower, lines could be upto two miles long. Great views and an exciting way to get to work/school for a relatively small amount of energy ? Frivolous or inspired ?
