Offshore Darrieus Turbine makes Clouds to turn deserts lush
An array of modified Darrieus (vertical
axis) Wind Turbines which each use their
captured mechanical power to pump
seawater through nozzles built into the
blades. Droplets give off water vapour,
leaving denser droplets to sink back to
the sea taking the salt with them. Humid
air forms clouds
which condense over
land, making rain. Rain falls, crops grow.
(optional globalisation extension: crops
are exported raising taxes to pay back
loan from IMF to buy turbines which are
Made In Scotland from Griders by
Struggling Scottish Shipbuilders)
This is not my idea but is a proposal
from my research supervisor, who is
doing a paper study of it. Thought you
guyz'n'gals would like it!

Is this your research supervisor? [jutta, Feb 19 2008]

Same source, but now - three years later - the salty droplets will increase the reflectivity of clouds. [jutta, Feb 19 2008]

||It's not at all clear to me that this would help green the deserts. As it is, the wind sweeping over the sea picks up both sea spray and water vapor. The Sahara is right next to the sea, and obviously doesn't benefit.
||Typical fuzzy logic from grant applications.
||P.S. Where can I get some of those griders?
||Shorter title please? Recent view is getting messed up...
||Don't we have enough clouds and rain in England?
||Send some to us, the poor farmers in Australia are buggered at the moment.
||If you could connect the cloud making turbines with 'The Tower of Power' (see link) you would really have something. Looks like Austraila is going to make a go of this skinflaps.
||I think I heard about this idea on BBC that the NPR station hear plays after midnight. Sounded crazy but I guess the best ideas usually do.
||Please explain the context for trying trying to turn unpopulated areas into farms, distant from where the product will be consumed. Like electricity the products of farms are invloved in a supply line that looses efficiency with distance.
|| Carbon fuel? Calories for starving people? (we seem to have a surplus) some sort of mass migration program? drought relief? It would work but I need a why.
