A wind-shielded acoustic sensor, having a microphone and a housing of the microphone. The housing has a streamlined, continuous profile about a latitudinal axis and a longitudinal axis thereof, such that wind-induced noise can be reduced. A plurality of uniformly spaced sound ports are formed along a plurality of circumferences centered about a longitudinal axis thereof. At least one region of the housing is sufficiently thin and pliable such that deformation will occur while subjected to wind. Thereby, both acoustic signals and wind-related random-like pressure fluctuations are transmitted into the cavity enclosed by the housing.

Wind-shielded acoustic sensor

A LMMHD power generation cell, having a fluid channel in which a conductive fluid is forced to flow in response to an external force. A pair of pressure conveying members such as bellow reservoirs can be used for conveying the external force to the conductive flow. A magnetic field is established across the fluid channel by a pair of magnets. A pair of electrodes is disposed with respect to the fluid channel to collect the electric current induced by the conductive fluid flowing through the magnetic field. The magnets are selected from either permanent magnets or electromagnets. Preferably, the conductive fluid is selected from low-density, low-viscosity, high-conductivity liquid metal such as NaK-78.
