Abstract: A generator system fluidly connected between a first preexisting pipe and a second preexisting pipe comprising a generator with a first preexisting pipe flange and a second preexisting pipe flange, without forming any holes in the first and second preexisting pipes. A first and second generator flange for engaging a non-magnetic section of pipe and the preexisting pipes and a plurality of coils secured to the non-magnetic section of pipe. A plurality of rare earth magnets secured to an outer surface of a rotating drum or a propeller and configured to energize the plurality of coils. At least one radial bearing, a thrust bearing and a junction box electrically connected to the plurality of coils for receiving energy produced by the plurality of coils and for transmitting a current.
