Turning sand into fuel silicon oil as an energy carrier ,silicon is more abundant than carbon. It oxidizes or combines with oxygen into silicon dioxide, which forms crystals present in rocks like quartz, basalt and granite. silicon dioxide is especially prevalent in sand which fills deserts and sea shores. We process silicon dioxide into glass and purify the silicon for use in electronics.
