|Abstract: ||An apparatus for energy extraction from fluid flow including an assembly
including a plenum. The assembly further includes an aperture extending
from an exterior surface to the plenum to allow flow therethrough. The
apparatus further includes a channel including an inlet and an outlet in
fluid communication with the plenum. The apparatus yet further includes
an energy extraction device. The assembly is configured to create a
pressure differential between the plenum and the inlet of the channel.
The pressure differential causes fluid flow from the inlet of the channel
to the plenum. The energy extraction device is configured to extract
energy from the fluid flow. The apparatus additionally includes a control
system configured to modify the pressure differential to control the
fluid flow between the inlet of the channel and the plenum based on a
characteristic of an exterior environment.
