It's such a fertile time in the green technology sector, solar power plants may soon begin reproducing. Using two resources that the Sahara has plenty of, sun and sand, the Sahara Solar Breeder Project hopes to build factories that will refine the sand's silica into silicon. That silicon will be used to build solar panels, which will power more silica-refining and solar panel factories, which will be able to build more solar panels, and on and on and on. The potential for exponential growth allows for some extreme optimism: The project's leaders say they could build enough power stations to meet half of the world's energy needs by 2050. Project leader Hideomi Koinuma believes the project is key to solving the world's energy crisis, saying:
"If we can use desert sand to make a substance that provides energy, this will be the key to solving the energy problem. This is probably doable. Moreover, the energy we continually receive from the Sun is 10,000 times the energy currently used by mankind. So if we can utilize 0.01% of it skillfully, we won't have a shortage of energy, but a surplus." [DigInfo TV]
