U.S. Senator Mike Crapo (R-ID) talks about Solar Roadways

Years ago, when the phrase "Global Warming" began gaining popularity, we started batting around the idea of replacing asphalt and concrete surfaces with solar panels that could be driven upon. We thought of the "black box" on airplanes: We didn't know what material that black box was made of, but it seemed to be able to protect sensitive electronics from the worst of airline crashes.

Suppose we made a section of road out of this material and housed solar cells to collect energy, which could pay for the cost of the panel, thereby creating a road that would pay for itself over time. What if we added LEDs to "paint" the road lines from beneath, lighting up the road for safer night time driving? What if we added a heating element in the surface (like the defrosting wire in the rear window of our cars) to prevent snow/ice accumulation in northern climates? The ideas and possibilities just continued to roll in and the Solar Roadway project was born.

In 2009, we received a contract from the Federal Highway Administration to build the first ever Solar Road Panel prototype. During the course of its construction, we learned many lessons and discovered new and better ways to approach this project. These methods and discoveries are discussed throughout this website. Please enjoy and send us any questions that you may have.

After successful completion of the Phase I SBIR contract, we were awarded a follow-up 2-year Phase II $750,000 SBIR contract by the Federal Highway Administration beginning in 2011. With this award, a prototype parking lot will be built and then tested under all weather and sunlight conditions.

The heart of the Solar Roadway™ is the

Solar Road Panel™

The Solar Roadway is a series of structurally-engineered solar panels that are driven upon. The idea is to replace all current petroleum-based asphalt roads, parking lots, and driveways with Solar Road Panels that collect energy to be used by our homes and businesses. Our ultimate goal is to be able to store excess energy in or alongside the Solar Roadways. This renewable energy replaces the need for the current fossil fuels used for the generation of electricity. This, in turn, cuts greenhouse gases literally in half.

Solar Road Panel

Each individual panel consists of three basic layers:

Road Surface Layer - translucent and high-strength, it is rough enough to provide great traction, yet still passes sunlight through to the solar collector cells embedded within, along with LEDs and a heating element. It is capable of handling today's heaviest loads under the worst of conditions. Weatherproof, it protects the electronics layer beneath it.

Electronics Layer Contains a microprocessor board with support circuitry for sensing loads on the surface and controlling a heating element. No more snow/ice removal and no more school/business closings due to inclement weather. The on-board microprocessor controls lighting, communications, monitoring, etc. With a communications device every 12 feet, the Solar Roadway is an intelligent highway system.

Base Plate LayerLayer - While the electronics layer collects energy from the sun, it is the base plate layer that distributes power (collected from the electronics layer) and data signals (phone, TV, internet, etc.) "downline" to all homes and businesses connected to the Solar Roadway. Weatherproof, it protects the electronics layer above it.

Scott presented the Solar Roadways at a TEDx Talk in Sacramento on April 16th, 2010. He was given 18 minutes for "The talk of his life" and it went great!

Overview

When multiple Solar Road Panels are interconnected, the intelligent Solar Roadway is formed. These panels replace current driveways, parking lots, and all road systems, be they interstate highways, state routes, downtown streets, residential streets, or even plain dirt or gravel country roads. Panels can also be used in amusement parks, raceways, bike paths, parking garage rooftops, remote military locations, etc. Any home or business connected to the Solar Roadway (via a Solar Road Panel driveway or parking lot) receives the power and data signals that the Solar Roadway provides. The Solar Roadway becomes an intelligent, self-healing, decentralized (secure) power grid.

Imagine a world-wide system where the "lit" half of the world is always powering the "dark" half of the world!

Everyone has power. No more power shortages, no more roaming power outages, no more need to burn coal (50% of greenhouse gases). Less need for fossil fuels and less dependency upon foreign oil. Much less pollution. How about this for a long term advantage: an electric road allows all-electric vehicles to recharge anywhere: rest stops, parking lots, etc. They would then have the same range as a gasoline-powered vehicle. Internal combustion engines would become obsolete. Our dependency on oil would come to an abrupt end.

It's time to upgrade our infrastructure - roads and power grid - to the 21st century.
