Engineers at MIT and in China are aiming to turn seawater into drinking water with a completely passive device that is inspired by the ocean, and powered by the sun.

In a paper appearing today in the journal Joule, the team outlines the design for a new solar desalination system that takes in saltwater and heats it with natural sunlight.

The researchers estimate that if the system is scaled up to the size of a small suitcase, it could produce about 4 to 6 liters of drinking water per hour and last several years before requiring replacement parts. At this scale and performance, the system could produce drinking water at a rate and price that is cheaper than tap water.

    primarily? That’s an exaggeration.

    • potassium > simply a banana
    • calcium > cheese, yoghurt, milk or if you’re vegan almonds and plant based milk, &c
    • magnesium > chocolate (cacao), nuts, spinach

    the list goes on and on. Yes, you’re right, if you drink distilled water, you have to pay attention to deficiency but it’s not a big deal. Water, unless it’s enriched artificially, has traces of these minerals.
