Abstract: Heat from a rotating prime mover(s) driving a fluid shear pump, heat from the prime mover and any exhaust heat generated by the prime mover is collected. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. This fluid heating process is performed in the absence of an open flame.

Abstract: Exposed fixture means and associated mounting features constituting a broad range of structural, aesthetic, and/or functional enhancements to existing recessed fixtures. Embodiments are generally configured to couple at a structural surface at and/or surrounding a recessed fixture. A mounting ring provides secure attachment at the structural surface, a ring cover typically engages with the mounting ring in a twist-lock engagement. An exposed fixture means (EFM) may be coupled at a side of the ring cover opposite the mounting ring. A system of correspondingly configured latch members of each of the ring cover and mounting ring enables relatively universal coupling of different EFMs at an already installed mounting ring. EFMs include a wide variety of aesthetic, functional, and/or structural embodiments.
