Claim 0:
1. A system, comprising:
a recirculation conduit that recirculates a working fluid, wherein the working fluid is a fuel being communicated to a combustor of a gas turbine engine; and
a permanent magnet generator in communication with the recirculation conduit such that the working fluid from the recirculation conduit drives the permanent magnet generator, wherein the permanent magnet generator comprises a turbine and a housing that contains the turbine and receives a portion of the working fluid from the recirculation conduit such that the working fluid drives the turbine, the working fluid thermally coupled to the permanent magnet generator through a cooling path formed within the housing, the working fluid configured to circulate through the cooling path providing thermal management of the permanent magnet generator.
