Distillation of water using solar energy is considered one of the most popular desalination methods today.

Power engineers at Ural Federal University (UrFU), together with colleagues from Iraq, have developed a new desalination technology, which is claimed to be much more effective than others, by incorporating a rotating cylinder. The method proposed by the UrFU power engineers will significantly reduce the cost of desalination and will increase production volumes by four times.

The experimental new solar distiller incorporates a rectangular basin, inside of which is a horizontally oriented black steel cylinder. The basin is filled with undrinkable water, and the cylinder is slowly rotated by a solar-powered DC motor.
