P Venkateshwar Reddy

Hello Ronald.

Interesting question, I follow your question, meanwhile while reading an article recently I got this answer.

A high-tech sieve that makes the ocean drinkable

Yes, you can already turn the ocean into drinkable water through existing, industrial-scale desalination plants. The whole world is facing problem of drinking water, so I think this invention can save the world.

Good Wishes

Roland Macana

Hi Reddy,

Thanks for you immediate answer. This is one way of making us updated about latest inventions all over the world.
