An electrical power generator employing a helically-vaned in-line rotor in a flow line as a prime mover means and as an integral part of the generator by effecting a cyclic variation in the density of permanent magnet generated flux fields which pass through fixed coil windings. Output voltage magnitude varies with rotor rotation rate which, in turn, varies as the flow rate of gas and/or fluid in the line.
