T.A.P. water for the Sahara

oops · January 6, 2021

A great idea to stop the advancement of the Sahara, provide water for drought ravaged countries, and help lessen greenhouse gases, but will itt ever happen?

TAP has designed a continental fresh-water pipeline to cross the Sahel area of Africa, beginning in the west in Mauritania, and culminating in the east at the Red Sea. TAP's pipeline is the first and only permanent solution to perennial drought throughout the Sahel and will mitigate the encroachment of the desert. Currently, thousands of hectares of land are lost to desertification every year across the Sahel countries of Africa.

Conceived and launched in Toronto, Canada, the Trans Africa Pipeline Inc. is a not-for-profit organization working in collaboration with the 11-country Pan African Great Green Wall (PAGGW) agency. TAP is also working with individual Sahel countries and with our U.S. charitable organization, the TAP Foundation U.S.

The Trans Africa Pipeline (TAP) project involves constructing an 8,000 km. fresh water pipeline (1.2 m to 1.5 m diameter) crossing 11 countries in the Sahel region of Africa. TAP's mission is to provide a sustainable supply of clean water for people and agriculture and support the goal of the Pan African Great Green Wall agency that involves the planting of millions of trees across a land corridor established by the 11 member countries.

Here’s another idea that was much talked about a few years ago:

The key to the water harvester is a new class of materials called metal-organic frameworks (MOFs). These MOFs are solid but porous materials with enormous surface areas—an MOF the size of sugar cube can have the internal surface area as big as many football fields. This means they can absorb gases and liquids, and then release them quickly when heat is added.

“Certain MOFs as we showed here have an extraordinary ability to suck in water vapor from the atmosphere, but then at the same time do not hold on to the water molecules inside their pores too tightly so that it is easy to get the water out,” says Omar Yaghi, a professor of chemistry at Berkeley, who led the research.
