ABSTRACT
This chapter suggests that the demand for magnesium as fuel source will rise rapidly in the market if its price falls to the range 100–150 yen/kg, and it will be competitive enough with gasoline. It shows that research on turning magnesium into fuel has been rarely heard of, and introduces a technology to use magnesium as fuel. The chapter summarizes the trends for the development of the next-generation car. As oil prices soar, natural gas and liquefaction coal will be secondarily used as alternative fuels. However, many of the developed countries have greenhouse gas control policies. The infrastructure for battery charging must be expanded in order to realize the convenience that the gasoline engine car has. Even if the entire country were saturated with infrastructure for battery charging, charging an electric car would take a lot more time compared with refueling a gasoline car.
