1. A climate controlled seat assembly, the climate controlled seat assembly comprising: a thermoelectric device comprising a main side and a waste side;a main heat exchanger coupled to the main side of the thermoelectric device for generating a conditioned fluid stream from a first fluid stream;a waste heat exchanger coupled to the waste side of the thermoelectric device for generating a waste fluid stream from a second fluid stream;a first fluid path in the seat assembly that directs the first fluid stream and the conditioned fluid stream to a seating surface configured to contact an occupant; anda second fluid path that directs the second fluid stream from a location proximate the seating surface to the waste heat exchanger via a conduit and the waste fluid stream away from the occupant, the conduit providing fluid communication between the location proximate the seating surface and the waste heat exchanger. 2. The climate controlled seat assembly of claim 1, further comprising a first pumping device fluidically coupled to at least one of the first fluid path and the second fluid path. 3. The climate controlled seat assembly of claim 2, further comprising a second pumping device, wherein the first pumping device is fluidically coupled to the first fluid path and the second pumping device is fluidically coupled to the second fluid path. 4. The climate controlled seat assembly of claim 3, wherein the first pumping device is positioned upstream of the main heat exchanger with respect to flow of the first fluid stream, and wherein the second pumping device is positioned downstream of the waste heat exchanger with respect to flow of the second fluid stream. 5. The climate controlled seat assembly of claim 2, wherein the first pumping device comprises: a rotor having a plurality of fins;a motor coupled to the rotor;a first inlet in fluid communication with a first outlet; anda second inlet in fluid communication with a second outlet,wherein the first inlet and the first outlet of the first pumping device are fluidically coupled to the first fluid path, and the second inlet and the second outlet are fluidically coupled to the second fluid path. 6. The climate controlled seat assembly of claim 5, wherein the main heat exchanger is positioned between the first inlet and the first outlet. 7. The climate controlled seat assembly of claim 1, wherein the conditioned fluid stream is directed to an occupant at or proximate a thigh area of a seat comprising the seating surface with the climate controlled seat assembly operating, wherein the seating surface is configured to contact the occupant. 8. The climate controlled seat assembly of claim 1, wherein a seat comprises the seating surface and a first fluid distribution system at or proximate a seat area of the seat. 9. The climate controlled seat assembly of claim 8, wherein the first fluid distribution system comprises channels extending laterally outwards towards sides of the seat. 10. The climate controlled seat assembly of claim 9, wherein the first fluid distribution system comprises an intermediate layer positioned between the channels and an overlying layer of the seat, the intermediate layer configured to maintain a gap between the channels and the overlying layer. 11. The climate controlled seat assembly of claim 10, wherein the overlying layer is a spacer fabric positioned between the intermediate layer and a cushion of the seat. 12. The climate controlled seat assembly of claim 8, wherein the seat comprises a second fluid distribution system at or proximate a thigh area of the seat. 13. The climate controlled seat assembly of claim 12, wherein the second fluid distribution system comprises channels extending laterally outwards towards sides of the seat. 14. The climate controlled seat assembly of claim 13, wherein the second fluid distribution system comprises an intermediate layer positioned between the channels and an overlying layer, the intermediate layer configured to maintain a gap between the channels and the overlying layer. 15. The climate controlled seat assembly of claim 1, wherein the second fluid stream is withdrawn at or proximate a lumbar region of a backrest comprising the seating surface with the climate controlled seat assembly operating. 16. The climate controlled seat assembly of claim 15, wherein the conditioned fluid stream is directed to the occupant at or proximate an upper back area of the backrest with the climate controlled seat assembly operating. 17. The climate controlled seat assembly of claim 1, wherein the first and second fluid paths are configured to direct the first and second fluid streams to cross-flow. 18. The climate controlled seat assembly of claim 1, wherein the second fluid path is configured to direct the second fluid stream through an exterior surface of the seating surface to the waste heat exchanger. 19. The climate controlled seat assembly of claim 1, wherein the location proximate the seating surface includes a side bolster of a seat comprising the seating surface, and wherein the second fluid path is configured to direct the second fluid stream from the side bolster, then laterally along the seat surface, and then to the waste heat exchanger. 20. A climate controlled seat assembly, the climate controlled seat assembly comprising: a thermoelectric device comprising a main side and a waste side;a main heat exchanger coupled to the main side of the thermoelectric device for generating a conditioned fluid stream from a first fluid stream; anda waste heat exchanger coupled to the waste side of the thermoelectric device for generating a waste fluid stream from a second fluid stream,wherein the conditioned fluid stream is directed to a location proximate a seating surface configured to contact an occupant with the climate controlled seat assembly operating,wherein the second fluid stream is withdrawn from a location proximate the seating surface configured to contact an occupant with the climate controlled seat assembly operating, andwherein the first fluid stream cross-flows with the second fluid stream with the climate controlled seat assembly operating. 21. The climate controlled seat assembly of claim 20, wherein the seat assembly comprises channels along top surfaces of the side bolsters from which the second fluid stream is withdrawn. 22. The climate controlled seat assembly of claim 20, wherein the conditioned fluid stream is directed to the occupant at or proximate a thigh area of a seat comprising the seating surface with the climate controlled seat assembly operating. 23. The climate controlled seat assembly of claim 20, wherein a seat comprises the seating surface and a first fluid distribution system at or proximate to a seat area of the seat, wherein the first fluid distribution system comprises channels extending laterally outwards towards sides of the seat. 24. A method of conditioning a seat assembly, the method comprising: producing a conditioned fluid stream from a first fluid stream;directing the conditioned fluid stream to a support surface configured to contact an occupant;withdrawing a second fluid stream from a location proximate the support surface; andcross-flowing the first fluid stream and the second fluid stream.
