The AutoBlog website reports that the idea put forward by theorists for laying solar-powered roads has been around for a while, and the process of perfecting the idea has been changing. The idea really makes sense. The roads that stretch millions of miles around the world usually absorb a lot of light, and most of the light is wasted. As long as humans find ways to solve their costs and endurance, the multi-million-mile pavement can do the job of double renewable energy. A German start-up called Solmove is doing this recently. Its approach is to install photovoltaic cells on the road. Yes, there have been other upstart implementation of this idea, such as the strange solar road system Solar Roadways. In the Netherlands and Canada, some agencies have succeeded in achieving solar energy within a smaller area. At the moment, the idea appears to be more viable on less-traffic roads, due to the undue impact of cars, trucks and other heavy machinery on conventional roads and highways. Solmove has now developed a glass road for non-motorized vehicles, which currently can only be used by bicycle or by foot and is not yet motor-driven. Solar highway conception map Solmove, headquartered in Germany, sees this as a rare opportunity. Compared with the United States, Solmove's products have more short-term potential in Germany. Earthly space means more to encourage the use of most of the unused surface area, and Germany is turning to renewable energy, whose energy demand is expected to rise. Donald Mueller Decaux, founder of Solmove, said: "There are many facilities in Germany that are small compared to the United States and there are many people here that maybe we can take advantage of the landscape and it is a smart way to take advantage of the facilities we are already using. Solmove will deploy its energy-using land-based project in the area near Haus der Zukunft in Berlin. The glass surface of the road reflects the sun's rays onto solar cells, with energy efficiency as high as 10% -15%. For reference, SolarCity's state-of-the-art rooftop solar panel system absorbs 22% of light energy and is said to be the most efficient in the world. As solar system costs fall and production increases, the use of solar energy will become more viable. In such a powerful country as Germany, energy and space needs will rise in the future, and it will be wise to adopt advanced technologies to find new ways to utilize resources such as space and energy.
