A couple sharpies have come up with a scheme for turning the nation's spaghetti bowl of roads and highways into a renewable-energy grid. It's a novel idea to "green up" a transportation network dominated by cars and trucks, a major source of climate-warming carbon dioxide.
The "Green Roadway" project, as it's dubbed, aims to string solar panels, wind turbines and geothermal devices along the endless ribbons of pavement, where they'll be linked to produce energy for businesses, homes and even roadside charging stations for electric-powered vehicles. Pictured above is a model of how a stretch of asphalt might look with a series of such gadgets; the blue rectangles are photovoltaic arrays, and the little umbrella-like objects depict turbines.
The two men behind the project, Gene Fein and Ed Merritt, say they've patented techniques and technology to generate commercial quantities of power this way. They hope to capitalize on a flood of government economic-stimulus money and tax breaks for clean energy projects by auctioning off rights to use their inventions in each of the 50 states. In Maryland, proponents say, just one 10-mile necklace of roadside solar or wind devices could power upwards of 2,000 homes.
"For me it's a billboard of hope," said Kelly Meyer, a prominent Southern California environmental activist who's spokesperson for the project. Head of the Natural Resources Defense Council's leadership council there, Meyer calls the project a "transition from old America to new America."
I leave it to sharper minds to say how practical or profitable this may be. The auction set for July 24 may be the test of that. To be sure, there are millions of miles of asphalt along which to build this alternative-energy grid. But I see potential bumps in the road for this plan to get over, if only from a scenic standpoint.
Some people object to the sight of wind turbines adorning their favorite vistas - atop mountain ridges and off ocean shores, for instance. State and local officials, ever wary of squeaky wheels, might be loath to grant widespread access to highway rights of way.
Meyer says these wind turbines won't be like the propellored behemoths that have stirred controversy in other settings. They'll be no more than 25 feet high, proponents say, and placed up to 500 feet back from the pavement.
But even if the roadside wind generators are less imposing, will motorists balk at having to peer between or over them to take in the scenery as they ride along? Would you find them just a high-tech form of windshield clutter? Or would you, like Meyer, see them as heartening signs that the country is finally coming to grips with its energy and environmental dilemma?
