Nearly 30,000 images showed gulls using France’s FLOATGEN turbine as a daytime rest stop and nighttime dormitory, while only two collisions appeared in nearly 2,000 analyzed flight sequences
1+ week, 4+ day ago (545+ words) Gulls are taking advantage of France’s offshore floating turbine during the day and night. Offshore wind energy has evolved from nearshore installations to deep-sea power generators. As more nations adopt the floating technology, understanding the potential wildlife impacts grows more…...
Sound Waves Power Tiny Robots That Can Fly, Float, and Move Without Motors
1+ week, 5+ day ago (372+ words) Tiny robots powered by sound waves are showing how robotics can move beyond traditional motors and batteries. Engineers at EPFL developed sound-powered robots that use hollow acoustic cavities to turn sound into directional thrust through Helmholtz resonance. These motorless robots…...

They spend the overwhelming majority of their lives airborne — hunting insects, navigating obstacles, roosting in high sheltered spots. Even their relationship with water happens from the air. They drink by skimming low over…...
Sonar mapped 27,000 barrels on the seafloor off Los Angeles, and the white halos ringing a third of them sit in sediment as caustic as household bleach rather than the pesticide anyone was looking for
1+ week, 6+ day ago (749+ words) Three thousand feet down there is no color left. The lights swing across flat grey mud, and a rusted drum comes up out of it. Around the drum the seabed has gone chalk white in a ring, hard edged against…...
An Ohio wind farm switched on ultrasonic “bat repellents” at 16 test turbines, and eastern red bat deaths roughly doubled instead of falling
2+ week, 1+ day ago (606+ words) Researchers found the best strategy to mitigate bat mortality based on an Ohio wind farm study. The United States’ clean energy needs have significantly changed since the rapid adoption of digital infrastructure. Higher electricity demands now require high-capacity generation, with…...
