     country truly running on solar power; however,
     just how feasible is this plan?

     For one, it would be quite costly. Each panel
     costs about $7,000 to build, and the plan calls
     for billions of them to cover the roadways
     [source: Telegraph.co.uk]. Installation would
     take huge amounts of time and money, and so
     would training crews to maintain them properly.
     Most likely, it would take several years before
     the electricitygenerated by the panels would
     recoup their own cost. For this reason, the
     company suggests smaller-scale projects are
     the best place to start.
     Then there's the question of durability. Our
