Scientists create a steel sphere device that could protect buildings from earthquakes without electricity

Innovative researchers have created an innovative seismic damper that utilizes steel balls and friction to mitigate the vibrations caused by earthquakes. Not requiring electricity or sophisticated electronics, early trials indicate a remarkable damping ratio of around fourteen percent. With its straightforward design, the device presents a cost-effective solution for earthquake safety. Additionally, this groundbreaking technology can aid in retrofitting older structures, enhancing their resilience against seismic activity.
