“Sustainable Society” is implemented as “Mag Soleil project”

<Modified as below>Prof. Kohama (Tohoku University) et al are now carrying out a "Mag Soliel project". A magnesium-contained material naturally occurring is smelted in the desert where solar energy density is extremely high. The resultant magnesium is transported to a target place. In the place the magnesium is converted into electrical energy and/or used as a light metal material as an industrial material. The magnesium oxide (MgO) produced after the magnesium is also smelted for its reuse.

Fossil fuel = 30 years, nuclear fuel = 50 years, and shale fuel = 200 years, the predicted longevities of the fuel resources. If future actual longevities of the fuel resources will deviate from those predictive longevities by 30% in the positive direction, the longevities of those resources are not so long.

After those energy resources are consumed up to exhaustion, how we should cope with the fuel or energy problem. The world population has exceeded 7 billion, and the population increase will yet continue. If we do not have the alternatives to the fuel resources, choices left us are to decrease energy consumption, to decrease the population, to bring energy resources from another celestial body, to stop energy consumption, to stop the sustaining of mankind, and so on. Those occurred to my mind.

A "sustainable society" has been presented to us, as a solution to the energy problem. We are seeking effective implementations of the concept of the sustainable society. A "Mag Soleil project" is one of the implementations. Prof. Kohama, Tohoku University, is carrying out the Mag Soleil project. The eco-friendliness is the preamble of the concept of the Mag Soleil project. The project based on the eco-friendliness has a mission to develop the technologies satisfying the eco-friendliness and to apply the development results to the society.

Solar energy and magnesium resources are almost limitless and eternally exist. The Mag Soleil project provides ready-for-use energy and materials by utilizing those resources. Used magnesium is smelted and used again, viz. it is recyclable. Substantially only the solar energy is used for the smelting process. Little load is imposed on the environment, with clean and low price energy.

Application of magnesium to new light materials is yet not large. Note that the magnesium has excellent properties when it is used as the practical metal#1. Efforts are being made to apply magnesium to vehicles #2. Prof. Kohama is progressively making application of magnesium to the high-speed transport system. Prof. Kohama also found the fact that the flame-retardant magnesium alloy is effective when it is applied to the battery, and is now developing a magnesium fuel cell, which will be described later in detail. The magnesium is little poisonous to the living body. Magnesium is really a future metal material.

Prof. Kohama says, "The MgFC powered by the magnesium smelted by solar energy can sufficiently supply the total energy consumed in Japan. The government should secure a desert including or near a bay area, for example, the Northern Australia."
Prof. Kohama advocates swiftly energy-shifting from the traditional energy such as nuclear energy and fossil energy to magnesium fuel energy. He made a rough estimate of the building cost of a 1,000,000 kW magnesium plant at about 1000 Oku-Yen. Its details consist of about 500 Oku-Yen (magnesium smelting plant) and about 500 Oku-Yen (MgFC plant). 1000 Oku-Yen is lower than the half of the nuclear power plant.
