Ireland has so many streams and rivers that could be harnessed. The Archimedas Screw is used very effectively to both harness the power from falling water and still allow the fish to travel upstream and downstream.

I wanted to know how it would be possible to resurrect thousands of old water power places which once were active in the beginning of the 20th century (about 60.000 - 80.000) in order to get more alternative power. Today there are only about 1000 - 2000 active. One big argument against is always that this constructions would harm fishs. But there are already a lot examples that these constuctions can even enhance the situation of the fishes. In the past there were no possibilities for fishes (i believe that, i don't know it) to get around watermills. Today there are so called fish staircases. The water volume before the watermill (usually tens of cubicmeters) is a safe place for fishes in summer, when water is scarce. The engineer told me that for a 5kW you have to calculate about 50.000 Euros for the turbine, the generator, the control system etc. Another 50.000 Euros you need to built the sluice valve, the rake, walls etc. Here is the link for the company (specialised on small turbines): http://www.hydrowatt.de/sites/english/home.html Some pictures of waterwheels: http://www.hydrowatt.de/sites/english/gallery/gallery.html A few months ago i called an engineer of the german company Hydrowatt in Karlsruhe (southwestern Germany, near Strasburg).

It seems low-tech & pretty simple to install. Thanks for this article – very interesting. It seems low-tech & pretty simple to install.
