Flooding the Sahara depressions !
How to save the climate ?
An urgent idea good for many !
Flooding the Sahara depressions, sea level will drop and evaporation increase, cooling the climate.
Investments good for the whole world, seas connected, easy with actual technology, projects leading to a peace spirit for everyones, improving life conditions of millions of people.
More than 12 depressions below sea levels could be filled by water, thanks to canals, tunnels, siphons or rains.
Other depressions above sea level will become lakes, new rivers will be created thanks to rains, snow will stay on Atlas and other mountains, evaporation will cool the climate and give a lot of food....
Less wars and migrations...
An idea supported by Tunisia, among others !

Even the CIA has explored the consequences of flooding the Qattara Depression in Libya. One advantage that intrigues modern engineers is the possibility of generating massive quantities of hydroelectric power. It would require a canal (or a pair of tunnels ,according to one proposal) only 40 miles long to connect the depression with the sea. The drop of 440 feet would be more than sufficient for the generation of power.

The idea of Huzel goes back to the second half of the nineteenth century. The aim was to divert waters of the Mediterranean Sea into the Sahara depressions in Tunisia and Algeria via a canal. The hope was that filling these depressions would alter the climate of the area. The history of the scheme is described in a comprehensive publication by Letolle and Bendjoudi (1997). They describe the geography, geology, hydrology and the socio-economic conditions of the project area. The following brief description is based on their work.
There is a vast depression in the Sahara running from the west of Gabès on the Mediterranean coast of Tunisia to the south-east of Biskra, with a general downward slope of east to west (Figure E.1). Chott Melrhir and Chott Rharsa in the western part of this depression, with an area of about 8000 km2, were proposed for flooding. It was believed that this depression was once part of the ancient Bay of Triton. Herodotus (485–425 bc) and other historians of antiquity described its shores as being highly rich and fertile.
Martins (1864) described that the last of the Chotts in the east is only 16 km away from the sea. By breaking through the Gabès ridge, the basin of the Chotts could become an inland sea. Lavigne (1869) described his observations of the area as a journalist, and raised the possibility of creating an inland sea.

Siphons from the sea to the Sahara
This is the maximum height that a siphon will work. Substituting values will give approximately 10 metres for water and, by definition of standard pressure, 0.76 metres (760 mm or 30 in) for mercury. The ratio of heights (about 13.6) equals the ratio of densities of water and mercury (at a given temperature). Note that as long as this condition is satisfied (pressure greater than zero), the flow at the output of the siphon is still only governed by the height difference between the source surface and the outlet. Volume of fluid in the apparatus is not relevant as long as the pressure head remains above zero in every section. Because pressure drops when velocity is increased, a static siphon (or manometer) can have a slightly higher height than a flowing siphon.
and solar ponds
Solar pond[edit]
At the Eddy Potash Mine in New Mexico, a technology called "salinity gradient solar pond" (SGSP) is being utilized to provide the energy needed by the mine. This method does not harness osmotic power, only solar power (see: solar pond). Sunlight reaching the bottom of the saltwater pond is absorbed as heat. The effect of natural convection, wherein "heat rises", is blocked using density differences between the three layers that make up the pond, in order to trap heat. The upper convection zone is the uppermost zone, followed by the stable gradient zone, then the bottom thermal zone. The stable gradient zone is the most important. The saltwater in this layer can not rise to the higher zone because the saltwater above has lower salinity and is therefore less-dense and more buoyant; and it can not sink to the lower level because that saltwater is denser. This middle zone, the stable gradient zone, effectively becomes an "insulator" for the bottom layer (although the main purpose is to block natural convection, since water is a poor insulator). This water from the lower layer, the storage zone, is pumped out and the heat is used to produce energy, usually by turbine in an organic Rankine cycle.[18]
In theory a solar pond could be used to generate osmotic power if evaporation from solar heat is used to create a salinity gradient, and the potential energy in this salinity gradient is harnessed directly using one of the first three methods above, such as the capacitive method.
Boron nitride nanotubes[edit]
A research team built an experimental system using boron nitride that produced much greater power than the Statoil prototype. It used an impermeable and electrically insulating membrane that was pierced by a single boron nitride nanotube with an external diameter of a few dozen nanometers. With this membrane separating a salt water reservoir and a fresh water reservoir, the team measured the electric current passing through the membrane using two electrodes immersed in the fluid either side of the nanotube.
The results showed the device was able to generate an electric current on the order of a nanoampere. The researchers claim this is 1,000 times the yield of other known techniques for harvesting osmotic energy and makes boron nitride nanotubes an extremely efficient solution for harvesting the energy of salinity gradients for usable electrical power.
The team claimed that a 1 square metre (11 sq ft) membrane could generate around 4 kW and be capable of generating up to 30 MWh per year.[19]
The Sahara is the largest hot desert in the world. Located in North Africa, its area is a whopping 3.5 million square miles, which is almost the size of the whole United States! It's a scorching hot place where very few lifeforms can survive. What few people know, however, is that it hasn’t always been like that. Every 41,000 years, the Sahara turns into a savannah grassland thanks to the movement of the Earth’s axis. Its next change of landscape is going to happen 15,000 years from now. But there is an idea that can make this process not just faster but different altogether. It’s called the Sahara Sea project…

SUMMARY:
- The first concept appeared in 1877 when Scottish entrepreneur Donald Mackenzie proposed to turn the El Djouf basin of the Sahara Desert into an inland sea.
- The following year, two French activists, Francois Elie Roudaire and Ferdinand de Lesseps, suggested a similar idea for the Chott el Fejej, another basin in the desert.
- It’s interesting that even Jules Verne was fascinated by the idea of creating a sea inside the world’s greatest desert. He wrote two adventure novels in 1877 and 1905 that dwelled on the matter and referred directly to Roudaire and de Lesseps’s plans.
- The first of the attempts to return to this issue was made in 1910 by French professor Edmund Etchegoyen. He was sure that an inland sea inside the Sahara would improve the climate in Europe.
- The Sahara Sea project’s second comeback was called on by members of Operation Plowshare. They proposed to blow up several explosives in the middle of the desert to create a basin that would then fill with water.
- There have been several initiatives in the 21st century, but the most promising one is called “The Sea in the Desert”. Its idea is to flood Chott El Jerid, one of the shallow salt lakes in southern Tunisia.
- Tunisia has a really high unemployment rate, and such a gigantic project would make the country’s economy skyrocket by providing jobs for approximately 60,000 people.
- The humid climate around the artificial sea would allow locals to farm the lands all year long, making a huge impact on the economy of the country.
- The Sea in the Desert project suggests there will be alternative energy generators installed after the main job is done.
