We all know that the amount of solar power produced is directly proportional to the size of the panel used. This means we need more surface area that should be covered with solar panels, if we think we need to get anywhere close to the amount of energy we use and need. According to a research the amount of solar energy that falls on Earth for one hour can provide enough energy to power the world for a year. It’s obvious that we cannot cover the entire planet with solar panels! A better alternative is to think of some place with a large surface area that can be covered with photovoltaic cells.
If we go by the calculations of Scott Brusaw that are no doubt based on a set of assumptions, then we will get to know that covering a mile long road with 10% efficient solar panels can provide enough power to run 500 homes. This has made Brusaw think about covering 1.7% of the U.S.’ land surface with solar panels. His company named Solar Roadways is devising a plan to cover the entire interstate highway system that covers close to 1.7% of the nation’s land surface with glass panels that could collect and distribute solar energy. The energy generated could be used to light the road at night, heat it in the winter and power buildings.
The system will consist of three superimposed layers, which would contain a revised version of the nation’s electric grid and a network of fiber optic cables. In addition to this the company will also make use of a ‘Smart System’ to warn drivers of impending construction, accidents and adverse weather events.
Brusaw hopes that the cost of producing a single 12′ X 12′ Solar Roadway panel could reach about $5,000. This means that Brusaw’s plan needs a massive $4.84 billion for implementation. This amount may seem too much for a plan that seems promising on paper but much difficult to implement, but considering this could save the planet from disaster, it deserves a try.
