Patent ID: 8069676

Claim:
A water vapor distillation system comprising: a water vapor distillation apparatus comprising: a source fluid input; an evaporator condenser apparatus comprising: a substantially cylindrical housing; and a plurality of tubes in said housing, whereby said source fluid input is fluidly connected to said evaporator condenser and said evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid; a heat exchanger fluidly connected to said source fluid input and a product fluid output, said heat exchanger comprising: an outer tube; and at least one inner tube; and a regenerative blower fluidly connected to said evaporator condenser, whereby said regenerative blower compresses steam, and whereby the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid; and a Stirling engine electrically connected to said water vapor distillation apparatus, wherein said Stirling engine at least partially powers said water vapor distillation apparatus wherein said Stirling engine comprising: at least one rocking drive mechanism comprising: a rocking beam having a rocker pivot: at least one cylinder; at least one piston, the piston housed within a respective cylinder whereby the piston is capable of substantially linearly reciprocating within the respective cylinder; and at least one coupling assembly having a proximal end and a distal end, the proximal end being connected to the piston and the distal end being connected to the rocking beam by an end pivot, whereby linear motion of the piston is converted to rotary motion of the rocking beam; a crankcase housing the rocking beam and housing a first portion of the coupling assembly; a crankshaft coupled to the rocking beam by way of a connecting rod, whereby the rotary motion of the rocking beam is transferred to the crankshaft; a working space housing the at least one cylinder, the at least one piston and a second portion of the coupling assembly; and a seal for sealing the workspace from the crankcase.
