Abstract: A fluidkinetic energy converter includes a passageway-filled enclosure. Turbines are mounted in the passageways and fluid flow may be concentrated on subparts of the turbines by inner fluid flow deflectors or dividers. The energy converter enclosure can include dividers at both inlets and outlets in order to be adaptable for either river or tidal environments. Notably, apart from the turbines and energy generating components, the enclosure may be implemented such as to have no moving parts, thereby reducing complexity, cost, and weight.
