An apparatus for providing electrical power includes a foil having a leading inlet, at least rotor internal to the foil and downstream from the inlet and a trailing flow separator partially within a trailing chamber. The apparatus also includes leading and trailing edges configured such that fluid flowing through the foil experiences decreased pressure and increased velocity at the trailing edges relative to the leading edges. In a method utilizing the disclosed apparatus within a fluid flow, a first quantity of a high-pressure fluid is passed, at a low velocity, into the leading inlet of the bypass foil. One or more rotors are rotated by the flow and the rotational energy is translated into electrical power with a generator. After turning the rotors, quantity of fluid is ejected, at a high velocity, to the trailing edges of the bypass foil at an area of low fluid pressure.
