Located in the Mur Valley of Styria, the Pernegg Demonstration Turbine is part of the Pernegg run-of-river hydropower plant complex operated by Verbund. The site serves as a public-facing educational centre, built around a full-scale turbine model housed in a custom-designed exhibition building adjacent to the operational plant. Installed as a teaching tool, the demonstration turbine replicates the structure and function of a real Francis turbine, including shaft, guide vanes, and generator components. Visitors can explore a cutaway model, engage with hands-on interactive displays, and observe real-time energy data. The facility aims to make hydropower technology visible and understandable to school groups, families, and curious members of the public. Engineering features include simplified control panels, water flow simulations, and sound/light installations that represent turbine action and grid transmission. While the demonstration turbine itself does not generate electricity, it mirrors the setup of the neighbouring working units, offering a safe and instructive experience.
Visits are available year-round by prior appointment and are best suited for school groups, technical colleges, and educational institutions. Guided tours typically last around 60 minutes and can be adapted for various age levels. The program includes a walkthrough of the demonstration hall, interactive media exhibits, and optional access to exterior viewing points of the operational Pernegg plant. Tours are conducted in German, but English-language materials and staff may be arranged on request. There is no entry fee for school or educational groups; private group visits may incur a small charge. The building is wheelchair accessible and equipped with restrooms. Group sizes are usually limited to ensure a high-quality experience, and all visits must be arranged through Verbund’s group booking system. Visitors are advised to dress for variable temperatures and bring curiosity—this site is designed for hands-on exploration rather than passive display.

Battersea Power Station, once the world’s largest brick building, supplied mid‑20th‑century London with electricity. Its Art Deco interiors and four chimneys remain central to the 2022 redevelopment into a mixed‑use complex. Guided tours explore restored Control Rooms and turbine halls, offering a striking example of industrial heritage conservation.
