"At first, half of the people who present the idea we considered geniuses and half lunatic. The hardness of the glass (which will run cars Ed.) Is found between the steel and stainless steel. It will create a proper infrastructure for electric vehicles in the form of shelters that can recharge, "said Scott Brusaw. Solar Roadway already investigating the use of mutual inductance to charge EV batteries while running on solar cars for the road.
America has currently over 72,500 square kilometers of asphalt roads covered with sun exposure. The energy produced by these panels covered roads would exceed three times the current production of energy to the U.S. and would eliminate the need for power plants. In 2009 alone, Americans consumed 3,741 billion kilowatt hours (kWh ) of electricity.
Founders were estimated efficiency solar panels roadways to 15%, and the lighting time thereof effective to 4 hours per day. in this way, a panel will produce 7.6 kWh per day, and one kilometer four-lane highway, 8,300 kWh per day. The panels are guaranteed for seven years, and the efficiency can be doubled depending on the technology used for production. A similar project in function on the intersection of two highways in the United States covering 740 square meters and produces 112,000 kWh.
After calculations Solar roadways would be required five billion 3.6 x 3.6 meter panels to cover all U.S. roads. That would mean a production that would generate jobs. Actual impediment still remains huge cost of a panel which reaches 7,000 a piece.
" At first light the solar panels do not work anymore, which is why we thought we should put a heating element on the surface. The lines on the road will be replaced with an LED system, and if there is someone on the road, a deer or a bicyclist, the road is so smart that warns the driver to slow down, "says Scott Brusaw, an electrical engineer by profession.
America loses 165 billion dollars annually in productivity because people are stuck in traffic due to repair works. On roads solar side is very easy, just replacing damaged panels.
In 2009, Solar roadways won a contract from the Federal Highway Administration to build the first prototype solar panel streets in the world. He later received a $ 750,000 grant from the same institution, to develop a covered parking with solar panels of this type to be tested in all different climatic and solar conditions.
