Why do bats fly into walls?

Bats excel in acoustic perception and detect objects as tiny as mosquitoes using sound waves. Echolocation permits them to calculate the three-dimensional location of both small and large objects, perceiving their shape, size and texture. To this end, a bat’s brain processes various acoustic dimensions from the echoes returning from the object such as frequency, […]

Buildings – Cool smart walls

Oak Ridge National Laboratory researchers used additive manufacturing to build a first-of-its kind smart wall called EMPOWER. The wall, designed for a building’s interior, also functions as a cooling system to optimize energy use and lower overall cost. The prototype wall was manufactured with a cable-driven, field deployable concrete additive manufacturing system and embedded with a thermal […]
