The new machine uses a hollow rotating cylinder to speed up the evaporation process.
The technology takes advantage of solar energy for the distillation of water, potentially allowing dirty water to be made clean for large parts of the world suffering from water shortages — the UN, for example, states that The team says that their method could significantly reduce the cost of desalination and multiply production volumes by four, they explained in a paper inTheir method utilizes a cylinder that is slowly rotated by a solar-powered DC motor.
"The performance improvement factor of the created solar distiller, compared to traditional devices, was at least 280% in the relatively hot months and at least 300% and 400% in the cooler months , at the same time, the cumulative water distillation capacity reached 12.5 l/m2 per day in summer and 3.
