Renewable energy cycle with magnesium and solar-energy-pumped lasers

Abstract

We report the recent progress of our proposed renewable energy cycle based on magnesium and solar-energy-pumped laser. The solar energy is used to recycle the used magnesium, MgO, to recover new magnesium and magnesium is used as fuel-cell battery. The batteries for the cell phone, automobiles and others have already been developed and demonstrated. The magnesium of 24kg is proven to drive a car for 500km without charging.
