Solar Panel Roads
As you can see, solar panels already have applications on our roads. But some are taking that idea even further and proposing that we build the roads themselves out of solar panels. Solar Roadways, a U.S. company, has a plan to create structurally engineered rows of solar panels that cars and trucks can actually drive on.
And while we're driving on them, they'll collect solar power that can supply power to our homes and businesses.
The "solar highways" consist of individual panels with three layers -- a top layer of high-strength, textured glass that provides traction for vehicles, an array of solar cells beneath that for gathering energy, and a base plate that distributes the collected power
They're more than just solar energy collectors, too.
The panels contain LED lights, powered by the sun, that can act as road and warning signs built into the road itself. In addition, they can use gathered heat to melt snow and ice on the roads.
The company also says that having a source of electricity beneath cars at all times would make it easy for electric vehicles to stay charged up at roadside stations -- clearing the major hurdle that EVs face, which is finding places to charge when they spend their batteries
With each 12-foot by 12-foot (3.7-meter by 3.7-meter) panel capable of producing 7.6-kilowatt hours of power each day, each mile of solar roadways could produce power to run as many as 500 homes.
