The electric highway – sounds almost romantic, doesn’t it? But in Sweden, things are getting real. They have built a highway that uses overhead cables to provide power to trucks, making them more efficient. How much more efficient? A typical 60 ton truck can save $83,000 over a 125,000 mile span. All that, with practically zero emissions while traveling at up to 56 mph. Which begs the question, do androids dream of electric highways?
