Underwater pendulums could calm waves and reduce coastal erosion
A tool to counteract the ability of waves might restrict erosion alongside coastlines Shutterstock / xander A system of upside-down pendulums tethered to the seafloor might considerably scale back the scale of waves, serving to restrict seaside erosion. Waves that wear down beaches are sometimes stopped with partitions of rocks constructed parallel to the shore, however these massive constructions are…
