This is an
extraordinarily important development. I
have posted on the advent of the Eden
machine which uses sunlight to draw down humidity from the atmosphere to water
an immediately adjacent tree or two. The
draw back was that it needed to store energy and needed high humidity to
perform well. This could be solved by
operating on the edge of deserts and slowly moving into the desert as the
growing trees slowly brought along the humidity.
This system
will completely accelerate the process by inducing multiple local thunderstorms
that support the increasing humidity that can then support the restoration of
forests, which expands the whole process far quicker.
Thus a first
phase would cover a chosen area were the upwind boundary area gets enough
humidity with ion emitters. If we are
clever, the power can be produced by windmills and it can also be a power
plant. The ionizers will be turned on
only when conditions permit.
With a long
band of ionizers in place the thunderstorms will strike in a downwind band. This will need to be captured with plenty of
trees. Over time the build up of
vegetation will stabilize humidity and bring on general rainfall.
Again, the
big trick is to determine the far edge of the desert for doing all this because
the expanding green belt supported by the Eden
machine protocol will cause steady down wind expansion.
The ionizers
by themselves are a great start but thunderstorms are naturally inefficient and
spotty. It is the trees that stabilize
it all.
The entire
Sahara and the deserts of the Middle East can
be now carpeted with schools of wind turbines and ionizers. The resulting thunderstorm bombardment will
recharge ground water everywhere and soon bring on natural forest regeneration
all of which increases and supports increasing general humidity.
In time, and
much sooner than I had ever hoped, such an enterprise would completely reforest
the whole region. We can do it. In fact, once the infrastructure is put in
place, the forest recovery will be almost exponential and completed to full
coverage inside perhaps fifty years.
Have scientists discovered how to create
downpours in the desert?

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.
Dry as
dust: The sand dunes of the United
Arab Emirates , which sees no rain at all for
months. Now a secret project has brought storms to Abu Dhabi
Plan:
Scientists are attempting to make clouds in the desert to give man control over
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.'

This is very exciting news. I am a Saudi and I have always thought there must be a way to produce rain. I had this grand idea of using heavy lift helium ballons to lift a large trapulin with an anchored base to higher atmospheres so that highly humid air could rise with the wind and start to form cumulu nimbus clouds. The trapulin would need to cover a large stretch of desert to work. But this idea is possible and I hope some day the Saudi government will become interested.
