RE: How scientists made a cheap new filter to purify water
This is great news. Perhaps it can be expanded to take the other hazardous wastes out of water. The heavy metals and harmful chemicals.
The we could all get safe, clean water. I'm sure the market would buy this in droves. And if it can eliminate hazardous wastes, then it would be easy to get water polluting factories to use it as well.
No one wants polluted water.
