 |  |  |  | Quote: Have scientists discovered how to create downpours in the desert? By DAILY MAIL REPORTER Last updated at 10:22 AM on 3rd January 2011
Technology created 50 rainstorms in Abu Dhabi's Al Ain region last year For centuries people living in the Middle East have dreamed of turning the sandy desert into land fit for growing crops with fresh water on tap. Now that holy grail is a step closer after scientists employed by the ruler of Abu Dhabi claim to have generated a series of downpours. Fifty rainstorms were created last year in the state's eastern Al Ain region using technology designed to control the weather.
Most of the storms were at the height of the summer in July and August when there is no rain at all. People living in Abu Dhabi were baffled by the rainfall which sometimes turned into hail and included gales and lightening.
HOW TECHNOLOGY IS KICKING UP A STORM The Metro System scientists used ionisers to produce negatively charged particles called electrons. They have a natural tendency to attach to tiny specks of dust which are ever-present in the atmosphere in the desert-regions. These are then carried up from the emitters by convection - upward currents of air generated by the heat release from sunlight as it hits the ground. Once the dust particles reach the right height for cloud formation, the charges will attract water molecules floating in the air which then start to condense around them. If there is sufficient moisture in the air, it induces billions of droplets to form which finally means cloud and rain. The scientists have been working secretly for United Arab Emirates president Sheikh Khalifa bin Zayed Al Nahyan. They have been using giant ionisers, shaped like stripped down lampshades on steel poles, to generate fields of negatively charged particles. These promote cloud formation and researchers hoped they could then produce rain.
In a confidential company video, the founder of the Swiss company in charge of the project, Metro Systems International, boasted of success. Helmut Fluhrer said: 'We have achieved a number of rainfalls.' It is believed to be the first time the system has produced rain from clear skies, according to the Sunday Times. In the past, China and other countries have used chemicals for cloud-seeding to both induce and prevent rain falling. Last June Metro Systems built five ionising sites each with 20 emitters which can send trillions of cloud-forming ions into the atmosphere. Over four summer months the emitters were switched on when the required atmospheric level of humidity reached 30 per cent or more. While the country's weather experts predicted no clouds or rain in the Al Ain region, rain fell on FIFTY-TWO occasions. The project was monitored by the Max Planck Institute for Meteorology, one of the world's major centres for atmospheric physics. Professor Hartmut Grassl, a former institute director, said: There are many applications. One is getting water into a dry area. 'Maybe this is a most important point for mankind.'
The savings using the Weathertec technology are huge with the system costing £6 million a year while desalination is £45 million. Building an ionising system is about £7 million while a desalination plant would be £850 million and costs a lot more to run. Some scientists are treating the results in Al Ain with caution because Abu Dhabi is a coastal state and can experience natural summer rainfall triggered by air picking up moisture from the warm ocean before dropping it on land. But the number of times it rained in the region so soon after the ionisers were switched on has encouraged researchers. Professor Peter Wilderer witnessed the experiments first hand and is backing the breakthrough. The director of advanced studies on sustainability at the Technical University of Munich, said: 'We came a big step closer to the point where we can increase the availability of fresh water to all in times of dramatic global changes.'

Oh well, the races at Yas Marina might get more interesting

This sounds ace. Think of all the land mass that's currently uninhabitable due to lack of water. This could go a long way to help making those places a viable place to live. Humans don't seem to be slowing down in their breeding, so we desperately need alternatives for habitable spaces, and this fits the bill. Perhaps it'll trigger worldwide tornados and an extinction level storm system. Who knows at this point? *shrug*

The problem is that they're not generating water. What falls on the desert clearly cannot fall where it normally would. So you're robbing Peter to pay Paul, as it were, except Peter is another nation who perhaps relies on the rain fall to prop up their meagre agricultural income. Dangerous technology, if indeed it's legit.

So Peter gets the same system. *shrug*

Paddy's nation is bankrupt, so he can STFU as that country can't afford anything. Mark

'Begorrah' etc... The one thing the earth as a planet is NOT short of is water. Just lots of it is in the wrong place, as least as far as humans are concerned. Given the climate scientists insistent that rising sea levels are imminent, technology which basically improves the hydrocycle for certain places may actually be a benefit in the long term. Fundamentally, what we need is a 'chain' system of some sort that uses the extra evaporation from the oceans and controls rainflow such that it falls in places which are currently arid. If we can do that in a controlled way it will be a good system. If we do it in an uncontrolled way, we could be in big trouble...

I'm not a meteorologist, but it states this system only works if there is 30% or higher humidity. Once that air has dropped it's load on Paul, it'll be arid by the time it reaches Paul.

I'm sure I read about this a few years ago. In that book. By that author. The one who did the dinosaur-thingy.
Goddammit.
Anyways, humans have a habit of f**king about with the ecosystem. This will not end well. What happens when others die because of a lack of crops/water/etc because someone wants a little lake in the desert (I forget what it's called)?

Sounds like someones had (still doing) a long shift?

I'm with the Egg man, better to "terraform" parts of the Earth than to look to Mars. I fear however said nation aren't the most environmentally sound of candidates to do, no matter how deep their purses.

Michael Crichton (if I've spelt that right)?

Completely forgot about this but yup it's Crichton (whose death I was completely oblivious to until I wikied him!).
Anyway in State of Fear, they try to use whether machines to wreak havoc and "show" people the dangers of global warming.
