Abstract: An evaporation sleeve is placed within a solar distillation loop apparatus to increase the amount of water evaporated by the apparatus. The evaporation sleeve is rotationally attached within the above ground portion of the solar distillation loop so the sleeve lifts impure water into the air flow within the system. The evaporation sleeve significantly increases the water surface area available to the air flow within a solar distillation loop.
