ABSTRACT:
A starting material including silica and carbon is heated to form an intermediate material. The intermediate material includes silica and silicon carbide. The intermediate material is reacted to form silicon. At least some of the emissions that are generated by heating the starting material and reacting the intermediate material are collected and used to generate electric power.
