A liquid desalination, distillation, disinfection, purification, or concentration system by repeatedly re-using thermal energy is provided. Thermal heat source can be solar, fossil fuel, or low grade heat discharged from industrial systems. Multiple thermally insulated and isolated stages of vaporization-condensation chambers can be connected to enhance production yield. Vapor is generated by direct heating of liquid and flash evaporation. Vapor generated is condensed in condenser cooled by intake liquid. Counter circulating intake liquid will be heated by released latent heat from vapor. Externally provided thermal energy will accumulate and be re-used in the system. Vaporization and condensation process will be continuously re-cycled to enhance production yield. The system can be configured to support flexible deployment in various configurations and in different locations, including direct floating installation on water surface.
