Do you remember the last time you stepped out on some hot asphalt or concrete on a sweltering summer day? You likely felt a tinge of the intense energy of the sun compacted into the over 4 million miles of roads that stretch across the United States. The US transportation system is vast, and it could just be ready for an enormous green facelift utilizing solar technologies.
This doesn’t include the millions of square miles of parking lots that go wasted every day as well, when they could be used to harness the energy of the sun. Not only could our roadways and parking lots be utilized to create energy for powering streetlights, buildings, businesses, and homes, but properly harnessed solar energy could turn iced-over roads and bridges into a thing of the past.
Solar roadways have been in development for over 20 years and the latest versions show real promise for helping to utilize some of the wide open spaces in this country – namely highways and parking lots – for energy creation. Inventor Scott Brusaw of Idaho has been working on a project to make roadways multi-purpose by replacing asphalt with solar panels. By covering the roads with highly tempered, textured,exceptionally strong glass panels that can collect the energy of the sun while taking the consistent load that a well-traveled road would anticipate, and joining that with a circuit board, lying underneath the glass, and connected to a vast computer system, our roads could turn into ‘smart roads,’ changing their own temperatures to accommodate inclement weather, and also gathering energy form the sun which could even be used to power our cars, buses, trains, and monorails.
“Just a 15 percent efficiency increase and we (would) produce three times more electricity that this country uses on an annual basis,” says Brusaw.
This could also be a game changer for electric cars – making the need for vast battery packs, obsolete. Makers of electric cars are already aware that millions of cars plugging into the current electricity grid could cause some major hiccups.
Solar roads would also lessen the need for asphalt, which makes the air toxic, and can cause some health issues for many people, especially children.
“New studies paint an increasingly alarming picture – particularly for young children – about how these chemicals are being spread across big swaths of American cities and suburbs by what may seem an unlikely source – a type of asphalt sealer. These sealants are derived from an industrial waste, coal tar.”
“We’re building solar panels that you can drive on,” Brusaw says. “The fact that it’s generating power means it pays for itself over time, as opposed to asphalt.” Bursaw and his wife, the inventors of the solar roadways created a small parking lot at its headquarters, using 108 solar panels to demonstrate its efficiency and strength. Vehicles have been driven onto the space, without damaging the panels, he said, “We’ll start off small with driveways and walkways.”
While revamping 4 million miles of roads could be quite an undertaking, the company has already raised $2.8 million for their long-term goal, with $850,000 in seed money coming from the federal government.
