Let’s talk science and some hard reality 71% of the earths surface is covered with water only about three percent of Earth’s water is freshwater. Of that, only about 1.2 percent can be used as drinking water; the rest is locked up in glaciers, ice caps, and permafrost, or buried deep in the ground. Most of our drinking water comes from rivers and streams. According to global census the worlds population is 8 billion a number that is mind blowing.

The reality is that the wars of the 21^st and 22^nd centuries (if we last that long) will not be over oil or land they will be over Water and the way we keep burning fossil fuels and heating the planet the amount of fresh water is going to be less. Yes we are, on a global level, trying to convert our power consumption to zero carb emitting sources but that is not going to change population growth or the finite amount of water on the planet.

As much as we need renewable energy we need to develop new technologies to desalinate water. Saudi Arabia and the UEA are building desalination plants but they are currently dependent on fossil fuels for the energy to produce potable water which in a zero carbon future is unsustainable. The other problem I see is the ability to transport the water over large distances, we need to develop a reverse river that not only moves the water but also pull the NaCl (salt) out of the water.

Theoretically salt can be removed through filtration and ultimately via rainout, which is a process of boiling water and collecting the stream which is fresh water. Universities should have their best and brightest trying to solve this problem and do it with renewable energy.

This is my non-engineer potential solution to develop the technology in North America.

Build a pipeline that runs from Baja California threw the Sonoran Desert and creates a Lake Meade size lake in Southern Arizona. Yes, I am aware that the path goes through Mexico but I see that as a positive not a negative because of the cooperation between both countries and the jobs it would generate on both sides of the boarder. The initial portion of the energy needed to push the water east would be provided threw wave energy then via pumping stations using a combination of wind and solar, both of which the desert has plenty. The pipes themselves would have charcoal and sediment micro filters that would gradually remove the salt from the sea water and near the end of the line rainout would be employed using solar to finalize the process.

I realize this a grand plan but think of the amount of good that could be created with this process. The pipeline itself would be roughly 220km long and realistically would require a pumping station every 15-20km , if it is 20km that is 11 pumping stations. At those stations there could be understandable run off areas. In brackish water sustainable Bamboo and other plants that can be used for bio fuels can be grown as well as Hemp which has a variety of positive uses. Also fisheries could be developed to harvest tilapia and salmon as well as a number of other fish. The fish could feed thousands and Bamboo forests in the desert would create a carbon sink that would help to slow global heating.

If our best mind could develop this technology, we could export it all over the planet and in our own way terraform areas that are currently unsustainable.

In the Immortal words of John Lennon,

You may say I’m a dreamer
But I’m not the only one
I hope someday you’ll join us
And the world will be as one

Let’s get to work on this a build a better world for the next generation.
