The technology charges the electronic device that could help you getting fresh water from salty seas.
The most used method is reverse osmosis that pushes water from a membrane that filters all the salt, but it is a costly and energy-intensive process. The battery method uses too much electricity to take salt ions out of the water, said by the researchers.
According to different application, The battery device can be small or large, While that reverse osmosis plants are very very large and cost-effective, as Smith said
the required pressure to pump the water through is much less, because it is too simple flowing the water over the electrodes instead of forcing it from a membrane.
It could recover 80 percent of desalinated water.
