Only 10% of people on Earth have access to safe water, says the Water Organization, a nonprofit headquartered in Chennai, India.
That means 90% may have to drink foul water, at a vast cost to their health. One obstacle to resolving the problem is that two key technologies, wastewater treatment and desalination, are very expensive, and very heavy on energy use.
Now an Israeli company [Aquanos] says it has a low-cost, energy-positive solution, notably appropriate for the capital-poor developing world – merely by adding aquatic weeds to the equation.
