Solar Roadways: 4 Reasons They Might Not Work

Over the last couple of weeks, ReWire's gotten a boatload of emails and social media forwards about the "Solar Freaking Roadways" Indiegogo campaign, in which inventors Julie and Scott Brusaw have raised well over $1.9 million to develop their modular solar-powered paving tiles. The Brusaws' goal is nothing less than replacing every bit of paved surface in the U.S. with the tiles, each of which will generate a maximum of 52 watts of electrical power when illuminated by the sun.

The Brusaws offer a vision of a nation that derives all its power from its roadways, which would include baked-in LEDs (to replace lane striping paint), heating elements to melt ice and snow, and integrated GPS. They claim that replacing our roadways with their panels will offer a source of solar energy enough to meet the United States' power needs three times over, with a roadway that's safer for pedestrians and animals.

As with any promise that sounds too good to be true, this one merits careful scrutiny -- especially since what the Brusaws are offering something a lot of us really want. Here are four reasons to take the Solar Roadways hype with a large amount of salt.
