Obtaining fresh drinking water is not easy for certain areas of the world. There has been constant research regarding various projects to convert non-drinkable water into something potable. Peng Wang of King Abdullah University and his team released their discoveries on the topic this week. The technology they use “recycles waste heat from photovoltaic (PV) solar panels using a multi-stage membrane distillation system to produce clean, drinkable water.” The idea is to be as useful as possible for those with limited access to fresh water such as in Africa and Asia. The benefits from the PV system alongside the yielding of water speak for themselves. However, looking at the bigger picture, it has potential to be used wherever there is a need for clean water- to irrigate plants, to clean, or even to colonize another planet.
