現在、私たちの豊かな生活は、石油、石炭、天然ガスなどの化石燃料によって支えられています。しかし、地球上に存在する化石燃料には限りがあり、石油は約40年、石炭は約160年、天然ガスは約70年で枯渇するといわれています。また、化石燃料は、地球温暖化や環境汚染などの深刻な問題の原因にもなっています。持続可能な社会の実現に向けて、化石燃料から再生可能な新エネルギーへの転換が求められています。

Today, our wealthy lives are supported by fossil fuels such as oil, coal and natural gas. However, fossil fuels on earth are limited, and it is said that petroleum will be depleted in about 40 years, coal will be depleted in about 160 years, and natural gas will be depleted in about 70 years. Fossil fuels are also causing serious problems such as global warming and environmental pollution. In order to realize a sustainable society, it is essential to switch from fossil fuels to renewable new energy.

Air and salt water (seawater) required for electric power generation are abundant on the earth. Magnesium is also the eighth most abundant element on Earth (Clark Number 8), accounting for about 2.5% of the earth’s crust. Approximately 0.13% is dissolved in seawater as an element, and about 1t of magnesium can be collected from 800t of seawater.

There is a prejudice that magnesium is flammable and dangerous, but magnesium used for water power generation is shaped into an ingot and there is no danger of ignition or explosion. In addition, since no toxic substances such as carbon monoxide are emitted during power generation, power can be safely generated even in closed rooms.
