What is Solar Roadways
Solar Roadways is a revolutionary concept that aims to replace traditional road surfaces with a product that can generate electricity, melt snow, and provide lighting. The idea was first imagined by Scott Brusaw as a little boy, and he and his wife Julie have been working tirelessly to bring it to life.
The Solar Roadways product is modular and incorporates photovoltaics to generate electricity. This means that roads can potentially become power-generating surfaces.

Scott and Julie Brusaw founded Solar Roadways in 2006 and began sharing their vision with the world. They started by discussing the benefits of using roadways for something besides a driving surface.
Their product features LEDs for lighting and messaging, and a textured tempered glass slip-resistant surface. This combination makes it a safe and functional alternative to traditional roads.
The Brusaws are starting with smaller installations like sidewalks, driveways, and parking lots to refine the product and its performance before moving on to streets and highways.
The Promise
Solar Roadways has been around since 2006, and the company has been making waves with its innovative product. Idaho-based Solar Roadways has been pushing the benefits of its solar roads for over a decade.
The company gained international attention with its viral 2014 video, Solar FREAKIN' Roadways. This video showcased the endless possibilities of solar roads.
Solar roads can change how people design, manage, and use roadways. By combining solar energy with cutting-edge technologies, these roads have the potential to make highways safer and environmentally sustainable.
Infrastructure and Roadways
Solar Roadways are an innovative way to generate clean energy, reduce road maintenance costs, and protect the environment. They can last up to 21 years before replacement, saving communities money.
The Brusaws, founders of Solar Roadways, started with smaller installations like sidewalks, driveways, and parking lots to refine their product and performance before moving on to streets and highways. They received a $100,000 SBIR grant from the Federal Highway Administration in 2009 to build their first Solar Road Panel prototype.
The Solar Roadways product is modular and incorporates photovoltaics to generate electricity, LEDs for lighting and messaging, and a textured tempered glass slip-resistant surface.
History
Infrastructure development in the United States began with the construction of the Erie Canal in 1817, which connected the Great Lakes to the Hudson River and revolutionized trade and commerce.
The first interstate highway, the Pennsylvania Turnpike, was completed in 1940 and was a major milestone in the development of the US highway system.
The Interstate Highway Act of 1956 was a significant piece of legislation that established the modern US highway system, with the goal of creating a network of high-speed roads that would facilitate the movement of goods and people across the country.
The construction of the Interstate Highway System required the relocation of over 1 million people, with many communities and businesses being displaced by the construction of highways.
The Interstate Highway System was designed to be a network of roads that would allow for the efficient movement of goods and people across the country, with an emphasis on high-speed travel and efficient traffic flow.

How It Works
Solar roads are a game-changer in the world of infrastructure and roadways. They work by producing solar energy while cars and trucks drive on them, serving a dual purpose.
The technology behind solar roads is quite impressive. There are three individual solar panel layers on solar roads: a base plate, a cluster of solar photovoltaic cells, and a top layer of high-strength, hexagonal tempered, and textured glass with traction for vehicles.
Solar roads will generate the most energy in the mornings and late afternoons when sunlight is the highest and traffic the heaviest. This is because the solar panels are designed to collect energy during these peak hours.
The design of solar roads allows them to be both functional and sustainable. They can feature additional equipment, such as heated panels and LED lighting, to melt ice and snow, power street and lane lights, and make driving safer and greener.
Here's a breakdown of the three individual solar panel layers found on solar roads:
- A base plate that distributes collected power
- A cluster of solar photovoltaic cells that gathers energy
- A top layer of high-strength, hexagonal tempered, and textured glass with traction for vehicles.
Improving Emergency Services
Solar roads can significantly improve emergency services by providing real-time information about road conditions, accidents, and breakdowns to relevant authorities through embedded technologies like LED lights and sensors.
Sensors can detect road incidents or hazardous road conditions and transmit that information instantly, leading to quicker emergency response times.
LED lights in solar roads are cost-effective and environmentally friendly, providing dynamic road markings that make driving more intuitive.
These lights can also power other safety features, such as pedestrian crossings, warning signs, and street lights, leading to improved levels of safety in communities.
Paired smartphones and advanced driver assistance systems like forward collision warnings can provide data for authorities to address or prevent accidents.

Roadways
Solar Roadways are a game-changer for the future of road infrastructure. The idea of using roadways to generate electricity, melt snow, and provide lighting is no longer just a pipe dream, thanks to the innovative work of Scott and Julie Brusaw.
Scott Brusaw first imagined "electric roads" as a little boy, and the idea stuck with him. He and his wife Julie have spent countless hours discussing the benefits of using roadways for something besides a driving surface.
The Solar Roadways product is modular and incorporates photovoltaics to generate electricity, LEDs for lighting and messaging, and a textured tempered glass slip-resistant surface. This makes it perfect for smaller installations like sidewalks, driveways, and parking lots.
In 2009, the Brusaws received a $100,000 Small Business Innovation Research (SBIR) grant from the Federal Highway Administration to build the first Solar Road Panel prototype. This was a huge milestone for their project.
Solar Roadways can last for 21 years before replacement, saving communities money that would normally go towards frequent traditional road repairs. According to the University of Minnesota Institute on the Environment, this makes them a cost-effective option in the long run.
The Brusaws' crowdfunding campaign in 2014 was a huge success, raising over $2.2 million in just two months. This shows that people are eager to invest in innovative and sustainable infrastructure solutions.

Challenges and Criticism
Solar Roadways have been met with criticism and challenges that question their feasibility. Jonathan Levine, a professor of urban planning, expressed doubt about the project's political feasibility on a national scale, suggesting a single town might be able to deploy it in a limited test case.
The cost of replacing all roads in the United States with Solar Roadways panels is estimated to be approximately $56 trillion, based on Scott Brusaw's cost estimate of $10,000 for a 12-by-12-foot section. This is a staggering amount that raises concerns about the project's financial viability.
Solar Roadways' choice of using glass for the surface of the panels has been criticized for being impractical. Journalist David Biello noted that the glass must be tempered, self-cleaning, and capable of transmitting light to the PV below under trying conditions, which is a type of glass that does not yet exist.
Engineers have struggled to make a solar road panel that can withstand heavy traffic loads while remaining transparent enough to let sunlight in. The WattWay project in France, for instance, had to reduce the speed limit to 43 miles per hour due to excessive noise from vehicles driving over the road surface.
Solar Roadways' low solar power production is another major concern. According to expert engineering analysis, they produce just one-third the power of solar panels of equivalent capacity in a solar power plant. This is due to several reasons, including the thickness of the glass surface and the design of the panels.
Here are some of the biggest challenges facing Solar Roadways:
- High cost: Estimated to be 3-4 times the price of a standard asphalt road.
- Can't handle traffic loads: Unable to withstand heavy vehicles while remaining transparent.
- Low solar power production: Produces just one-third the power of solar panels in a solar power plant.
- Safety and noise concerns: Glass surface may not provide sufficient traction for fast-moving vehicular traffic.
Despite these challenges, companies like Solar Roadways and Colas still hope to make solar roadways a workable option. However, it seems unlikely to happen soon – if ever.

Reality and Impact
Solar Roadways has been generating hype for years, but what have they actually achieved?
After successfully generating hype, Solar Roadways has yet to make a significant impact on the market. They have been unable to deliver on their initial promises.
The company has been working on their product for over a decade, but it seems they still have a long way to go.
The Reality

Solar Roadways has achieved very little in terms of actual implementation, despite generating hype for years. The company's website still lists the same goals and promises made in 2014, with no concrete updates on their progress.
They did manage to secure a $4.3 million grant from the US Department of Transportation in 2014 to develop their solar panel technology.
Their innovative technology was supposed to be integrated into roads, providing a sustainable source of energy and even warning signs for drivers. However, it seems that's still in the development phase.
The company's social media presence has been relatively quiet in recent years, with few updates on their projects or timelines.
Despite the lack of progress, Solar Roadways is not the only company working on similar projects.

Have Made No
Solar Roadways have made no solar roadways. The only place their product has been used is in their pilot project: a small 150-square-foot installation of walkway in their hometown of Sandpoint, Idaho, installed in 2016.
A project on Route 66 in Missouri was supposed to be a solar sidewalk alongside the highway, but it fell through before a single road panel was laid.
Their initial rollout suffered a fire in its electrical system and then failed to melt snow that fell upon it.
