Abstract: An electric power generator for placement inline with a conduit comprises a substantially cylindrical housing defining a non-magnetic elongated chamber configured to be coupled to the conduit so that a fluid flowing in the conduit flows through the elongated chamber, an impeller defining a central channel disposed in the elongated chamber and an inner surface of the central channel having a plurality of blade members shaping fluid flow in the central channel, where the impeller further including a matrix of permanent magnets secured to an exterior surface wall. The generator further comprises a copper coil assembly coupled to the substantially cylindrical housing and comprising a plurality of copper coils arranged circumferentially about the cylindrical housing, and configured to interact with the matrix of permanent magnets to generate electricity when the impeller rotates due to fluid flowing in the central channel and acting on the blade members.
