Is powdered water a cure for drought ?

A special new absorbent material could soon be making its way to arid regions to help farmers grow crops.

Known as "Solid Rain", the remarkable material is capable of absorbing large amounts of water and then releasing it slowly over a long period of time. Based on materials normally found in ultra-absorbent diapers, just 10 grams of the product can absorb as much as a litre of water. Developed by Sergio Jesus Rico Velasco, the material could make it possible to grow bumper crops in otherwise nonviable arid regions.

"It works by encapsulating the water, and our product lasts 8 to 10 years in the ground, depending on the water quality - if you use pure water, it lasts longer," said the company's vice president Edwin Gonzalez.

"There has been a great deal of excitement and some dramatic headlines in recent weeks about a product that is said to have the potential to overcome the global challenge of growing crops in arid conditions."

However, the tech already exists to CHEAPLY produce water from fresh air "At the edge of the Atacama Desert, one of the driest places on earth, Lima, Peru, receives almost no rainfall. About 700,000 people have no access to clean water for drinking or bathing. Another 600,000 of the city's 7.5 million residents rely on cisterns for their water, which must be filled by pumps or by hand and cleaned regularly. But Lima's Pacific Coast location experiences humidity of more than 90 percent on summer days, from December to February. So engineers from Peru's University of Engineering and Technology (... [More]

http://www.bbc.co.uk...onment-23715031 No. It can't replace water. It is polyacrylamide. I've used and tested it for use in windbreaks. Results were disappointing to say the least. What it can do is even out the availability of water. When water is available, it absorbs and holds it. If there are frequent rainstorms or frequent irrigation, it evens out the flow. But if a drought occurs, the polyacrylamide release its water to the soil, rather than the plant. In the tests I ran, it made no discernible difference to tree survival or growth. But it does offer some excellent practical joking oppor... [More]

Those scientists should look into converting used nappies into a fertilizer/water thingy for the arid area crops. Thereby taking care of the whole overload of used nappies in our landfills.

So it ends up in your body ? Is that safe ? " After it disintegrates, the powder-like substance becomes part of the plant - it is not toxic,
