Norwegian Engineers Create “Damless” Hydropower System Using Air Pressure Instead of Dams 🌊⚙️ In a groundbreaking renewable energy experiment, engineers in Norway have developed a new “damless” hydropower system that generates electricity using air pressure — not massive concrete walls. Tested along a western fjord, the container-sized prototype channels flowing water into a sealed chamber, where the force of the current compresses air. That air pressure is then released to spin turbines, produ
