Can't create nothing from nothing--still need 30% humidity. But this would be a good start to reverse the expansion of the Sahara and the Gobi.
http://www.arabianbusiness.com/abu-dhabi-backed-scientists-create-fake-rainstorms-in-11m-project-371038.htmlScientists working for the Abu Dhabi government created more than 50 rainstorms in Al Ain in July and August of 2010, during the peak of the emirate’s summer months.
The rains are part of a secret $11m project, reportedly commissioned by HH Sheikh Khalifa bin Zayed Al Nahyan, President of the UAE, which used ionisers to generate storms, the UK’s Sunday Times said.
It is thought to be the first time the team had produced man-made rain from otherwise clear skies.
According to the report, scientists used large ionisers, which resemble lampshades, to generate fields of negatively charged particles. That in turn creates cloud formation, leading to rain.
Over 122 days through the summer months, the emitters were switched on 74 times when atmospheric humidity reached the required level of 30 percent or more.
During that time, Al AIn experienced rainfall on 52 occasions on days when the country’s own weather service had predicted no clouds and no rain.
The fake storms went so far as to produce hail, wind gales and even lightning, baffling residents.
