Life might take a hammering on the sun's earthly anvil, the Sahara desert, but the two most abundant resources the desert has to offer – sunlight and sand – could help solar power to "breed" and thrive there.


The Sahara Solar Breeder Project is a joint initiative by universities in Japan and Algeria that aims to build enough solar power stations by 2050 to supply 50 per cent of the energy used by humanity.


The idea is to begin by building a small number of silicon manufacturing plants in the Sahara, each turning the desert sand into the high-quality silicon needed to build solar panels. Once those panels are operating, some of the energy they generate will be used to build more silicon plants, each churning out more solar panels and generating more energy that can be used to build even more plants, and so on.
