The silica can be used to build vast solar arrays which will then provide the power and means to build more solar arrays in a classic breeder model. They would then use DC powerlines utilizing high temperature superconductors. The lead of the project points out that silica is the second most abundant resource in the Earth's crust. The project's lofty goals to harness the Sahara's energy has a few requirements — including 100 million yen annually — but also the worldwide cooperation of many nations and the training of the scientists and engineers to create and man these desert plants. The once deadly wasteland of the Sahara now looks like a land rich in an important resource: sunlight."
