    A news report about how Japanese scientists are hoping to turn the Sahara Desert into a giant solar power plant:

    This project will use the world’s biggest desert, the Sahara, as an energy source. Deserts have ample sunlight over a vast area, and their sand contains lots of silica – the raw material for silicon. So the idea is to build silicon manufacturing plants around the desert and solar power plants in the desert, and use the power generated to build more silicon and power plants in a “breeding” process. In the future, such plants could supply energy worldwide, through DC power lines using high-temperature superconductors.
