Caption

A modern water wheel - only a few meters from where I live, built in 2000 to gain electricity by a company named HydroWatt.

This small power station produces 26 kW of electrical power, a year estimate of about 150.000 kWh, which saves 96 tons of CO2 a year and thus helps to preserve our precious climate - together with lots of other small but renewable sources of energy like solar power stations, windmills etc.

The wheel is 2.9 m in diameter and 4 m wide. It uses the water of a channel running through all of Freiburg coming from the river Dreisam. The main purpose of this 'Gewerbebach' was to support local small industry with water and energy.

I would very much like to see those small water power stations more often...

Behind the scene : how this panorama was made

I didn't use too much energy this time to find some spectacular subject and simply shot the water wheel I can see all day on the way to our local supermarket.

But it was a challenge anyway. Not so much because there were rats running acros my feet or because I wanted to stand in the water. It was the dynamic range. More than 12 f-stops between the darkest shadows and the sunlit buildings outside.

I had to choose a relatively long exposure time in order too look into the shadows, hence the wheel and the water is pretty 'dynamic'. And it was my second attempt: I tried to shoot it for the 'Water' event too, but failed. You can see the previous result (after very much photoshop work) at http://pano.erik-krause.de/water/ (bottom pano).
