Instead of needing constant power, new system adjusts to use whatever is available. //

“Unlike reverse osmosis, electrodialysis is an electrically driven process,” Bessette says. The membranes are arranged in such a way that the water is not pushed through them but flows along them. On both sides of those membranes are positive and negative electrodes that create an electric field, which draws salt ions through the membranes and out of the water. //

The two most important parameters in electrodialysis desalination are the flow rate of the water and the power you apply to the electrodes. To make the process efficient, you need to match those two. The advantage of electrodialysis is that it can operate at different power levels. When you have more available power, you can just pump more water through the system. When you have less power, you can slow the system down by reducing the water flow rate. You’ll produce less freshwater, but you won’t break anything this way. //

On average, it desalinated around 5,000 liters of water per day—enough for a community of roughly 2,000 people.
Is 2.5L per day really enough per person when that is below the adequate intake levels according to the Institute of Medicine? Let alone for other purposes such as cooking and hygiene.

The Institute of Medicine has recommended adequate intake (AI) values for total water at levels to prevent dehydration. The AI for men aged 19+ is 3.7 liters each day, and 3 liters (13 cups) of which should be consumed as beverages. The AI for women aged 19+ is 2.7 liters about 2.2 liters (9 cups) of which should be consumed as beverages each day.

Like most other things in medicine and science there are different viewpoints on what total water intake needs to be. This study says an average minimum of 1.8 L. I've seen several textbooks that list anything from 1.5 to 2.5 L. I've also see other estimates going as high as 3.5-4 L. Age, sex, renal function, diet, and metabolic disease all have impacts on these numbers.
