Rjukan is known for its hydroelectric power station and solar mirrors.
Rjukan lies at the bottom of a valley that is oriented east to west, with Gaustatoppen (at 1883 metres over sea level) and the other surrounding mountains immediately south of the town rendering the city sun-free from September to March.
The founder of Rjukan Sam Eyde (wikipedia) launched the idea in 1913 of a “Solspeil”, or sun mirror, above Rjukan. He saw the importance of giving his workers the opportunities for sunlight in the winter.
High on the mountain opposite, 450 metres above the town, there are 3 mirros ,each 17 metres in area,
These three large, solar-powered, computer-controlled mirrors steadily track the movement of the sun across the sky, reflecting its rays down on to the square and bathing it in bright sunlight. Rjukan – or at least, a small but vital part of Rjukan – is no longer stuck where the sun don't shine.

Norsk Hydro Rjukan
Norsk Hydro Rjukan is an industrial facility operated by Norsk Hydro at Rjukan in Tinn, Norway, from 1911 to 1991.
The plant manufactured chemicals related to the production of fertilizer, initially potassium nitrate from arc-produced nitric acid and later ammonia, hydrogen, and heavy water. The location was chosen for its vicinity to hydroelectric power plants built in the Måna river.
30 million tonnes of products, equivalent of 1.5 million wagon loads, were produced in Rjukan. After the closing parts of the plants and the railway have been preserved. (Source: Wikipedia)
