Dear MEL Topic Readers,
The floating desalination machines powered by the waves
As the world’s population grows at an unprecedented speed, having added
two billion since the millennium, the world needs more water. However, global
warming and extreme weather conditions make it harder to provide stable water
supply to many regions. The good news is that we have plenty of water in the
oceans and seas. If we could desalinate the seawater in sustainable ways, we
would be able to provide clean, fresh water for many people. In fact, over 300
million people today use desalinated water in the world, and the demand for
desalination plants is increasing. However, most of the conventional thermal
desalination plants are highly energy-intensive and use fossil fuels to heat
seawater. Another desalination method is the membrane system, which pushes seawater
through a semi-permeable membrane to remove the salt. This technology uses less
energy than the thermal system but it still requires quite a lot of energy. So,
a Canadian start-up came up with a new floating desalination technology that
uses a membrane system powered only by the movement of the waves. Of course,
water conservation should be the first priority and step to securing clean
water for people, plants, and animals, new technologies are on their way for
sustainable development.
Enjoy reading the article and learning about new, sustainable ways to
produce fresh water.
