Recycling of CO(2) into methanol, dimethyl ether (DME), and derived fuels and materials is a feasible approach to address our carbon conundrum. It would free humankind from its dependence on fossil fuel while at the same time help mitigate the problems associated with excessive CO(2) emission. The energy needed for this carbon cycle can come from renewable sources (hydro, solar, wind) as well as atomic energy.
