Road power plant generate electricity

In U.S. and Europe, engineers working to equip streets with solar cells, over which even trucks can roll. That could produce enough power for electric cars, replacing a part of conventional power plants. In the United States, just a start-up has equipped with walk-in solar panels ranks first.

Start up solar roadways begins quite modestly with one thing that could become quite large. American company now moved the first solar modules on a road in the small town of Sandpoint, Idaho, United States.

They are so resilient that even truck it away can roll without destroying it, the developers promise. The first panels are however not a street, but in a public place, so that they are not too heavily strained.

Topped with light-emitting diodes

So are the modules, has solar roadways garnished them with light-emitting diodes, which only a little bit consume the electricity generated. The rest powered the pump of a fountain and the illumination of a public toilet.

In the winter, when the Sun is less intense and less power is produced, still less for the practical application remains. Because part of the generated flow are for integrated heating elements, which keep the modules free of snow in Idaho, the winters are harsh and snowy. A positive side effect: power-generating streets would never again ice adversely affected.

Power on the bike path

In the Netherlands, there is already a little further. Near Amsterdam, a cycle track in operation, which is paved for a distance of 70 m with solar cells is two years. It produces up to 10,000 kWh per year. This is sufficient for the year by almost three German average households. Would be 42,000 of 140,000 km of roads in the Netherlands so made up, there enough power to completely switching to electric cars, work out the builders.

1000 kilometers solar highway in France

France presses for still more vigorously. Colar, a subsidiary of French construction giant of Bouygues, specializing in transport infrastructure will cover a 1000 kilometer-long road with solar panels by 2020. referred 20 m2 of the Wattways system kWh of electricity would produce about 4000 a year.

The first 15 m are already installed in the vicinity of Marseille. The entire road would generate electricity for five million people, as Colas. But should he be cached somewhere. To the public power grid could be used if it were flexible enough that other power plants power gaps could stuff around in the night. Expensive batteries would otherwise be necessary.

How German engineers exorcise the risk of slipping

In Germany the RWTH Aachen engineers on the development of traffic. The modules should 5 mm be strong and on the surface with little nubs are equipped, to give the necessary grip the tires. Together with Solmove in Inning am Ammersee and the Fraunhofer Institute for solar energy systems, the Aachener develop such traffic. Power from the road can “perspective all nuclear power plants to replace”, it says on the Solmove homepage.
