Sahara Solar Breeder Project Aims to Power Half the World by 2050

The Sahara Desert has two things in abundance: sun and sand. What if those could both be used symbiotically to eventually provide half the world's energy?  Talk about huge ideas. A team of scientists from the University of Tokyo are teaming up with Algerian universities on this "Sahara Solar Breeder Project."

 

Not to rain on the ambition. It's a pretty remarkable idea, and it's dumbfounding that nobody has yet attempted to use desert sand as a source of silicon for PV panels. Koinuma recognizes that the challenges ahead are massive, and is focused on that essential first step: turning desert silica into silicon of high enough purity to be used in photovoltaic panels.

But if this can be accomplished, and a single solar plant can be built in the Sahara, then the process can almost certainly be scaled up. Koinuma, for one, is optimistic.
