Photovoltaic devices were laid on the road, and this is the idea of ​​Kurt Bursa. His company, Solar Roads, is embedding photovoltaic cells and light-emitting diode ( LED ) light sources into panels that can withstand traffic pressure. These LED light sources will make "smart" roads and parking lots feasible, and the markings can change, and the battery will generate enough energy to power the enterprise, the city, and ultimately the entire country.
Each 12 x 12 ft solar road panel will generate approximately 7600 watt-hours of electricity per day, calculated as an average of 4 hours of light per day. At this rate, a one-mile, four-lane road segment will power 500 or so homes. "If we replace all the roads in the United States, then we will be able to generate more electricity than our country needs," Bursa said. Bursa, an electronics engineer, completed his first prototype panel in February, funded by the US Department of Transportation.
Strong sunlight hits the road, wasting energy. Then take a look at Scott Bursa's plan to build a road using solar panels, the solar road of Cote Bursa.
Bursa's goal is to reduce the cost of each panel to less than $10,000. This is about three times the cost of asphalt. But he wants the life of the panel to be more than three times the life of the asphalt road. At present, asphalt roads in many places must be re-paved every 10 years. "If this is the case, the cost will be almost the same," he said. "But that's just break even, and we can generate electricity."
The key technology for its commercial viability is panel glass. The glass must have an embossed structure to create traction, a heating element embedded to melt the snow and ice, and can carry traffic for several years. “The trickiest problem will be,†Bursa said. “If there is a 40-ton truck driving in a fast lane on the road, it might be equipped with a non-slip tire chain. The panel must withstand that level.†At the same time, if you want Let the sunlight reach the photovoltaic cell, the glass must also have self-cleaning ability; Bursa pointed out that the hydrophilic glass in the experimental stage can use sunlight to decompose organic dirt and use rain water to rinse without leaving stains.
The next step for the solar road is to obtain the second phase of funding, a two-year, $750,000 agreement to develop a panel business plan. At the end of the second year, Bursa will be ready to test in the parking lot. He believes that the parking lot is an excellent test site for testing LED light sources and power generation systems. Directional arrows and parking lines can be reconfigured to handle peak hours, and the power generated can power nearby businesses. “I have talked to people in charge of power at Wal-Mart,†Bursa said. “The supermarket is about 200,000 square feet, and the parking area is about four times. I calculated the 800,000 square foot parking lot and told him how much power would be generated, even if it was completely full. That would be 10 times the amount of electricity they use."
However, Bursa wants to start a smaller restaurant on a smaller scale. McDonald's modified solar parking can make it largely or completely out of the grid, or become a charging station for electric vehicles (natural when the owner enters the meal). “Even the best electric car is only about three hours away,†he explained. "But if I have to find a McDonald's, I will drive from Idaho to the southern tip of Florida." Isn't it possible? Yes. But "providing billions of watts of electricity" will be a new and enticing slogan.
