The two boys turned seawater into fresh water thanks to the waves

Their machine is fully powered by natural energy, an effective and extremely environmentally friendly method.

It turns seawater into fresh water thanks to ocean waves

Justin Sonnett and Chris Matthews, two students who just graduated from North Carolina University, said they have found a solution to solve the problem of global clean water, by turning seawater into fresh water.

Justin Sonnett, co-founder of SAROS.

They call their solution SAROS (reverse osmosis water system). Accordingly, the machine can remove salt from saltwater, using a high pressure pump. What comes especially from that energy will come from the waves where SAROS is installed. The final product will definitely drink.

Of course, the most interesting thing about this machine is from the energy it uses. The waves are easy to find in the sea, one of the most vulnerable areas of freshwater, and thus the marine environment will not be affected by fossil energy waste.

SAROS machines were pushed to the sea on a buoy, with a built-in pendulum. This pendulum is the part that receives energy from waves. Here's how it works and creates clean water.

Process of creating clean water of SAROS.

"It is a much more expensive method of dissipation than traditional desalination machines, not only that, but its performance is also higher , " Sonnett told reporters. "In addition, it is also very environmentally friendly, so you will not have to worry about energy shortage in coastal areas."

This system can produce 2,000 liters of water per day, 10-year lifespan and only production cost of about 23,000 USD. SAROS systems will aim at installation in areas that need sustainability and small ranges. In the short term, two guys are planning to use their system to provide drinking water in some areas for the state of California, USA.

The biggest problem with these two guys is the capital, there are currently no investors who believe in SAROS's profitability."It's hard to get the trust of investors," Sonnett said.

Anyway, SAROS has made the list of 30 potential projects at the recent Hello Tomorrow conference in Paris. And above all, this is a community-oriented project, anyone can imagine what SAROS will bring if it is replicated in many parts of the world.
