The scythe museum of Scharnstein is installed in the old building of the former forge Geyerhammer. The plant is in the condition as it was run until 1987. Water wheels were the source of energy for the hammers and other machines of the plant. In 2006 a small hydropower plant was put into operation. In the power house runs a simple controlled Kaplan turbine with a power of 103 kW. To generate this power the turbine it needs a water flow of 6 m³/s. The annual output is approximately 600000 kWh.
