Embodiments of the invention provide systems and methods for water purification and desalination. The systems have a preheater, a degasser, multiple evaporation chambers with demisters, heat pipes, and a control system, wherein the control system permits continuous operation of the purification and desalination system without requiring user intervention or cleaning. The system is capable of recovering heat from each distillation stage, while removing, from a contaminated water sample, a plurality of contaminant types including: microbiological contaminants, radiological contaminants, metals, salts, volatile organics, and non-volatile organics.

1. A water purification and desalination system comprising a plurality of fluid-process components, heat-transfer components, and a control system, wherein: the fluid-process components define a fluid-process pathway of fluid flow from a water inlet for contaminated water to outlets for products and for waste, and wherein each component along the fluid-process pathway is in fluid communication with at least one adjacent fluid-process component, and wherein the fluid-process components comprise, in order of fluid flow: the water inlet, at least two modules, and said outlets;wherein each module comprises an evaporation chamber and a product condenser, and wherein heat of condensation in the condenser of one module is transferred to the evaporation chamber of an adjacent module by at least one heat pipe;the system further comprising a heating chamber proximate to a first evaporation chamber; wherein heat from the heating chamber creates steam in the first evaporation chamber which enters a first condenser; wherein the first condenser is proximate to a second evaporation chamber, such that subsequent modules convey heat recovered from condensation in one module via the at least one heat pipe to evaporate water in an adjacent module. 2. The system of claim 1, wherein the product condenser yields purified water with levels of all contaminants below the levels shown in the MCL Column of Table 1, when the contaminated water has levels of the contaminants that are up to 1000 times greater than the levels shown in the MCL Column of Table 1. 3. The system of claim 1, wherein the product condenser yields purified water with levels of all contaminants below the levels shown in the MCL Column of Table 1, when the contaminated water has levels of the contaminants that are at least 1000 times greater than the levels shown in the MCL Column of Table 1. 4. The system of claim 1, wherein the distillation energy is provided from a source selected from the group consisting of electricity, waste heat, and combustion, of oil, hydrocarbons, or natural gas. 5. The system of claim 1, wherein the control system permits continuous purification and desalination of inlet water without requiring user intervention, cleaning, or maintenance for at least one year. 6. The system of claim 1, wherein the fluid-process components remove, from a contaminated water sample, at least one contaminant selected from the group consisting of microbiological contaminants, radiological contaminants, metals, salts, and organics. 7. The system of claim 1, wherein the fluid-process components additionally comprise a preheater, which uses excess heat from the fluid-process components to preheat a contaminated water, thus reducing overall energy consumption. 8. The system of claim 1, wherein the fluid-process components additionally comprise a degasser, which removes organics, volatiles, and soluble gases from the water. 9. The system of claim 1, wherein the fluid-process components additionally comprise a demister between the evaporation chamber and the product condenser, which separates clean steam from waste steam and sends clean steam to the product condenser. 10. The system of claim 1, comprising both a degasser and a demister, wherein the evaporation chamber collects water from the degasser and sends steam to the demister. 11. The system of claim 1, wherein the volume of purified water produced is between 20% and 99% of a volume of input water. 12. The system of claim 1, wherein the system does not require cleaning through at least two months of use. 13. The system of claim 1, wherein the system does not require cleaning through at least one year of use. 14. The system of claim 1, further comprising an inlet switch to regulate flow of water through the inlet. 15. The system of claim 14, wherein the inlet switch comprises a mechanism selected from the group consisting of a solenoid, a valve, and an aperture. 16. The system of claim 14, wherein the inlet switch is controlled by the control system. 17. The system of claim 1, further comprising a shutdown control. 18. The system of claim 17, wherein the shutdown control is selected from the group consisting of a manual control, a flood control, a condenser capacity control, and an evaporation chamber capacity control. 19. The system of claim 18, wherein the control system controls the inlet based upon feedback from at least one of a temperature sensor in an evaporation chamber, a condenser float, and a flood detector. 20. The system of claim 16, wherein the control system controls the inlet switch based upon feedback from the water purification and desalination system. 21. The system of claim 20, wherein the feedback is based upon at least one characteristic selected from the group consisting of: amount of water in a product water container, flow of product water through the product outlet, time of water flow, time of no water flow, amount of water in the evaporation chamber, detection of a leak, evaporation chamber pressure, output water quality as determined by measuring total dissolved solids, pressure differential across the evaporation chamber, and movement of water across an evaporation chamber overflow weir float. 22. A method of water purification and desalination using the system of claim 1 comprising the steps of: providing a source of inlet contaminated water;passing the inlet contaminated water through the system andyielding purified water. 23. The method of claim 22, wherein the product condenser yields purified water with levels of all contaminants below the levels shown in the MCL Column of Table 1, when the contaminated water has levels of the contaminants that are up to 1000 times greater than the levels shown in the MCL Column of Table 1. 24. The method of claim 22, wherein the product condenser yields purified water with levels of all contaminants below the levels shown in the MCL Column of Table 1, when the contaminated water has levels of the contaminants that are at least 1000 times greater than the levels shown in the MCL Column of Table 1.
