Americans have found a way to never run out of drinking water again

news hardware Americans have found a way to never run out of drinking water again

Scientists at Massachusetts Institute of Technology (MIT) are actively working on a portable desalination device capable of efficiently producing drinking water from seawater, hoping to address the world’s shortage.

The climate crisis, which is slowly but surely spreading across the world, is already beginning to have very damaging consequences for human life. In particular, droughts are contributing to increasing scarcity of drinking water in various parts of the world, leading many scientists to look for ways to bring drinking water to where it is badly needed.

A case for desalinating water

In this context it is thisA team of MIT researchers led by Junghyo Yoon has developed a relatively compact device capable of desalinating seawater. Named ICPWaterTechthe machine, which is currently in prototype, does not filter salt water but uses a technique called “Polarization of Ion Concentration” (ICP). It means thatit applies an electric field to the water, which repels both positively and negatively charged particles. These include salt molecules, but also bacteria and viruses.

Since this process is not sufficient to completely remove all salt particles, the researchers complemented it with an electrodialysis step. The water that comes out of the machine after these two treatments is not only desalinated but also desalinated It is also purified to make it perfectly suitable for consumption.

A promising process that needs to be perfected

The MIT prototype is currently capable of this produce up to 0.3 liters of drinking water per hour : It’s not much, but it’s just the beginning. In addition, the other advantage of the device is thatit uses only 20 watt-hours per liter of desalinated water, allowing operation with a simple portable solar panel. The following video shows the device in operation.

This system, which was presented for the first time in 2021, received last year an award given by the J-WAFS (Abdul Latif Jameel Water & Food Systems Lab) as part of World Water Day. Various prizes are awarded every year to scientific projects related to the most important resource on our planet.

MIT scientists and engineers are now planning to do soimprove the performance of their machine and work on a marketable version, which could see the light of day in the coming years. What is certain is that such a device could be of great help in many parts of the world in the coming decades.
