IMAGINE THAT A PLANET CAN HAPPEN WHERE “WIRED” AND “GRIDS” COULD GIVE ACCESS TO “NONE-TOXIC ENVIRONMENTAL HARMING ENERGIES”??//!!! “ITS CALLED INFRASTRUCTURE(S)” AND PRESIDENT BIDEN AND TEAM MATES AND VICE PRESIDENT HARRIS ARE “TOTALLY TRUE/TRUTH” ON THE RIGHT PATHS!@! “BIDEN-HARRIS” ADMINISTRATION!!
SOME PEOPLE, WHO DENY “GLOBAL WARMING” AND “ENVIRONMENTAL CLIMATE CHANGE”, ALSO DENY WHAT CONSTITUTES “INFRASTRUCTURE”!!!
IMAGINE BEING “BETTER” AND “BUILDING BACK BETTER” AND NOT GOING BACKWARDS TO THE “MAGA-TYPE” CRAZINESS OF THE HORSE AND BUGGY AND SLAVE TRADE DAYS; BUT, HEADING INTO THE HERE AND NOW/FUTURISTIC FUTURE, HAVING LEARNED OUR LESSONS AND RETAINING KNOWLEDGE OF A FEW THINGS TO BE BETTER THAN EVER!!!??/// “YES. WE CAN”!!!!
ITS ALMOST, “NOW” BECOMING A “ZERO-SUMS-GAME” OF THE FUTURE OF THE EARTH. UNLESS, YOU BELIEVE THAT WE SHOULD ALLOW THE EARTH TO “BURN UP” WHICH COULD BE SOME PEOPLE’S RELIGIOUS BELIEFS THAT WHEN GODS BIBLES SAY HE WILL DESTROY THE EARTH BY “FIRE”; CRAZIES WANT TO MAKE IT HAPPEN SOONER AND SOONER!…???//!!! “FIRE DOES CLEANSE”! BUT, SUFFERING OF THE EARTHLY CREATURES, INCLUDING HUMANS WILL BE MASSIVE, FOR THOUSANDS OF YEARS, BEFORE THE EVENTUAL ENDING AND “SPONTANEOUS IGNITION HAPPENS”!!!
Concept Phase:
The Solar Roadways® journey began on an ordinary day as most life changing adventures do. Scott and Julie had known each other since they were small children, in southern California in the 1960’s when roads and highways looked, well – just like they do today!Read More
SR1:
The next big event was the USDOT’s SBIR solicitation, looking for a new pavement system that could help pay for itself with the generation of renewable energy. We applied for the Phase I SBIR (Small Business Innovation Research) contract and received the $100,000 six-month award. Read More
SR2:
We were awarded a 2-year $750,000 Phase II SBIR contract by the USDOT in July of 2011. This funding allowed us to conduct more research and build the world’s first prototype solar parking lot Read More

Phase I Research
August, 2009 Solar Roadways Incorporated is awarded a Phase I SBIR (Small Business Innovative Research) contract by the U.S. Department of Transportation. The 6-month $100,000 Phase I contract is for “a detailed concept that demonstrates the viability of creating a prototype that satisfies the attributes described below:
- It generates its own power; either through the energy of the sun or perhaps the energy of the moving vehicle mass traveling over the pavement.
- It is intelligent enough to transfer the power generated to where it is most needed or to a temporary storage apparatus.
- It is made of recycled or other sustainable materials.
- It can be modular for ease of replacing worn or damaged sections.
- It is durable enough to withstand repeated loading from heavy traffic at or above the level of current pavement systems
- It meets or exceeds safety characteristics of existing pavement systems.
- It mitigates water runoff through either permeability or designed retention and filtration.
- It is at a cost that allows it to be financially self-sustaining; meaning that the benefits of power generation and water runoff mitigation over the design life outweigh its initial cost.
Glass
To make a solar panel that could withstand the abuse of fully-loaded semi-trucks, a protective case had to be created to protect the sensitive solar cells and electronics inside. In addition, the surface of this case had to be transparent to allow the sunlight to reach the solar cells inside.
Deciding what to make this protective case out of was a materials engineering problem. Scott Brusaw is an electrical engineer (BEE, MSEE), so he looked up the top materials research labs in the nation. Penn State’s Materials Research Institute and the University of Dayton’s Research Institute were at the top of the list. Scott traveled to both universities and met with their materials research professors. Both research labs, without hesitation, suggested the use of glass for the surface. Unlike plastic, the optical properties of glass are stable against solarization (long-term darkening) and other UV induced mechanisms of material degradation. Float glass was recommended due to its widespread commercial availability and relatively low cost.
Testing the transmittance of float glassFloat glass comes in different forms. The greenish glass shown above is called soda lime glass and is the most common type. Windows and bottles are typically made of soda lime glass. The green tint is caused by the iron content of the glass. This same iron content negatively affects the transmittance (ability to pass sunlight) of the glass, so a low-iron glass was selected.
Due to the very limited budget of the Phase I prototype, glass was only studied, but not yet used during this round of funding. The findings were applied in Phase II.
Stormwater
Stormwater is just rain or melting snow that makes its way from our roads to our waterways. Imagine a heavy downpour: the stormwater flows across lawns/fields and picks up fertilizer, pesticides, etc. It then flows into the street, where it picks up vehicle droppings such as oil, antifreeze, etc. Currently, this toxic cocktail finds its way into our streams, rivers, lakes, and oceans. Some studies show that over 50-percent of water pollution is caused by stormwater.
Capturing and filtering the stormwater before it reaches the waterways could solve the problem. A physicist/hydrologist who visited us once shared that, if we could move water just 200 miles in this country, we could eliminate drought conditions.
By lining the sides of our roadways with stormwater retention systems, we could do the initial filtering. By including pumps, the stormwater could then be moved to areas for additional filtering and then to aquafers or agricultural centers. In colder climates, the stormwater could be stored below the frost line to prevent freezing.

The SR1 was designed around a 32×32 array of LED cells. Each cell contains 3 white and 3 yellow LEDs to simulate any road line paint configuration. This required 64 circuit boards to create the 12-foot by 12-foot SR1. 12-feet is the largest standard U.S. lane width. Another circuit board was needed for the microprocessor control unit.
LED circuit board – 64 boards per panel
Microprocessor board Scott Brusaw designed the two circuit boards required. 68 of the LED circuit boards were assembled and tested: 64 for the SR1 and another four for a prototype crosswalk panel. Three microprocessor boards were assembled and tested. These were the control/communications boards for the stormwater control system, the Solar Road Panel, and the Sidewalk Panel. An XBee RF module was added to the microprocessor board to incorporate wireless communication.
Scott then wrote the firmware for the microprocessor boards. A software program was needed for testing and control, including:
Configure which LEDs would turn on/off
Control the stormwater pumps
Read/control the crosswalk panel
Scott concurrently wrote the firmware and software programs for the desired interactions.

Assembly
Once all of the testing was done, it was time to assemble the panels. Our budget only allowed for a crude proof-of-concept prototype. Plastic was used for its ease of machining.
Assembling the prototypes
We assembled the panels, tested them, and filmed a demonstration of the system. Helpers were on hand and Mark Dixon of YERT was visiting from Pennsylvania to do the filming.
Once everything was repaired and running properly, filming began and pictures were taken.
