Yes, the British scientists, engineers finally completed the construction of "solar" w / e the bridge project, which was launched back in 2009. Somewhere Habré, I remember, there was an article about the start of construction, but could not find.
So, during the construction of the bridge Blackfriars, which is part of the Blackfriars Station in London, has been used 4,400 solar panels covering an area of 6,000 square meters.
The total capacity of the panels - 1, 1 MW of electricity. According to the authors of the project, the bridge provides about half the energy of a whole station. By itself, is worth bearing in mind that London - not the sunniest place on the planet.
Bridge equipment solar panels - is not the goal of the project, it is - part of a larger project, Thameslink Programme, which aims to -increase capacity of railways of the capital of Great Britain, as well as reducing harmful emissions from train / railway UK.
However, this bridge - one of the most interesting and "green" parts of the project. The authors expect that the solar panels will generate a bridge about 900 thousand kWh of electricity per year. The bridge itself was built in Victorian times, so that the engineers had to try to upgrade it.
