More recently, universities in Japan and Algeria have launched a joint initiative called the Sahara Solar Breeder Project, with the incredibly ambitious goal to "build enough solar power stations by 2050 to supply 50 per cent of the energy used by humanity". The plan is to build a solar breeder in the Sahara desert, and convert sand there to silicon wafers used in solar panels:

The project was first proposed by Hideomi Koinuma from the Science Council of Japan, at the 2009 G8+5 Academies' Meeting in Rome:

Despite many news reports on this project, details are hard to find, so it is difficult to tell how seriously to take it.
