In Saudi Arabia, a team of researchers developed a water purification device. And that device not only keeps water free of contaminants but also produces free electricity. According to a report, over 780 million people across the world do not have access to clean water.

Water purification is the only way to make drinking water available to lot of people around the world. But the process of water purification is a lengthy one and consumes a lot of electricity. That is the reason many citizens of the developing countries do not have clean water to drink.

A team of researchers in Saudi Arabia made an invention. They invented a device that solves the two problems- water purification and electricity. And it uses solar power to produce electricity. The electricity in turn helps with purifying the water.

This process is a hit for the arid regions just like Saudi Arabia, where there is lot of sun and scarcity of drinking water. And the good news behind this invention is it is not just for industrial use. According to the researchers, you can set up this device in your home and generate power and have clean water at the same time. This makes one of the best house hard water filter along with solving the problems of electricity.

Pen Wang, the researcher and the co-author of the Cosmos Magazine said- “The generated clean water an be used for cleaning solar panels to remove dust particles, it can be used to irrigate plants and crops, making desert agriculture possible.”

In a paper published on Nature Communications, they explained the workings of this water purifier. The top of the device has a horizontal commercial silicon solar cell fitted on it. And then directly below the cell there are several tiers to filter the contaminated water.

The process of water passing through the tier produces clean water as well as heat. Earlier researchers just used saline water, but now the device purifies sea water even contaminated with copper, lead, sodium, potassium and calcium.
