The human-caused climate change made the ‘Day Zero’ drought in southwestern South Africa — named after the day when Cape Town’s municipal water supply would need to be shut off — five to six times more likely.
The scientists adapted a solar panel that not only generated power, but used some of the heat energy to distill and purify sea water. The idea could make a major difference in sunny climates with limited water supplies.
Changing people's perspectives to see waste as a resource will take some time, but trial initiatives are already underway in places like Costa Brava, Sweden, Romania and a variety of sites across Europe.
A newly developed sorbent-based technology has recently shown that it can harvest atmospheric moisture even when the relative humidity drops to around 10 percent.
Although Cape Town has pushed back day zero – the day that the city runs out of water – until June 4, the country re-assessed the magnitude of the drought and determined that it has reached disaster proportions.
The drought-stricken city announced that it will begin marking 200 collection points where its 3.7 million residents will be required to queue for a rationed supply of water on ‘Day Zero’ – currently forecast to be April 21, 2018.
SOURCE panels can be installed atop any building just like a standard photovoltaic, but harvests drinking water in addition to solar energy.

Silicon Valley rose as water use restrictions kicked in.
Without planning and cooperation, EU countries could be up against a water problem.
