German scientist Helmut F. Schulze worked seven years on this so called "Waterproof Sand". The large rolls sandwich the sand between layers of polyethylene and can be produced in lengths of up to 50 meters. "The coating is done in 30 or 45 sec," said Hareb. "We have the capacity of manufacturing 3,000 tonnes per day."
The plant is already in talks with potential customers such as the Dubai Municipality which has inquired about the product as it will work towards greening the Emirate. By simply laying down a 10-centimeter blanket of DIME Hydrophobic Materials sand beneach typical desert topsoil, the new ueber sand stops water below the roots level of the plants and maintains a water table, giving greenery a constant water supply.

Based on Kitegen’s current evaluations, their wind generators would have a much lower electric energy production cost than any of the current wind farms and would be able to generate up to 250 MW/km2, (vs. the current 3 MW/km2).
Its amazing to think that kiteboarding kites could revolution the windpower future – but actually just a few years back when I was just learning how to kite, ant the kite went into the death spin – it was pretty clear to me how much power this kite technology is capable of. View the prototype test video.
