A spectrogram of Bloop. Bloop is the name given to an ultra-low-frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in 1997. The sound is consistent with the noises generated by icequakes in large icebergs, or large icebergs scraping the ocean floor. [3]
This mechanism could explain the Bloop's wide detection range and distinct acoustic signature. [7] As oceanographer Yunbo Xie explains, the alteration of waveforms from a detected sound "can also be caused by so-called angular frequency dependent radiation patterns associated with antisymmetric mode motion of the ice cover."

The free-piston linear generator (FPLG) uses chemical energy from fuel to drive magnets through a stator and converts this linear motion into electric energy. Because of its versatility, low weight and high efficiency, it can be used in a wide range of applications, although it is of special interest to the mobility industry as range extenders for electric vehicles.
Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
A range extender is a fuel-based auxiliary power unit (APU) that extends the range of a battery electric vehicle by driving an electric generator that charges the vehicle's battery. This arrangement is known as a series hybrid drivetrain. The most commonly used range extenders are internal combustion engines, but fuel-cells or other engine ...
Uber driver Derek Gooderham was zipping along on Interstate 83 when a wave of wood planks tumbled from the lumber truck, sliding down a hill and sweeping his car off the road.
“Wait for the man who randomly tears up because he’s so in love," Madison Perrott wrote alongside the sweet clip of her boyfriend of over a year
In broadcast engineering, a frequency extender is an electronic device that expands the usable frequency range of POTS telephone lines. [1] It also allows high-fidelity analog audio to be sent over regular telephone lines, without the loss of lower audio frequencies . It is an extended concept of a telephone hybrid.
