  • Magma energy power plant

    As the current renewable energy is unstable1, Magma energy should be utilized for generating a huge amount of electric power instead of consuming natural gas, coal, petroleum, nuclear, and other fuels2. Magma with the lifetime of 0.1 to 1 million years has never been used for generating electric power in the world. If we were to succeed the magma power plant, the existing fuel-consuming power plants can be replaced with it. The conventional geothermal power generators use the steam from the earth for generating electric power. In the magma power system, high temperature heats from magma around 1000 ℃ can be used to generate strong steam for driving the steam turbine in the power plant.

    We have been seeking for natural high-heat sources. We have discovered that Japan has unlimited heat energy sources: magma heat energy. Although geothermal power generation has been studied for many years, in the conventional geothermal power generation, steam or vapor from earth is used to drive the steam turbine for generating electric power. Why not, directly use the magma heat of 1000 ℃ temperature using the heat pipe in order to transfer the high temperature heat to the steam turbine. It is now possible to design and develop the magma power plant where the high temperature heat pipe up to 2000℃ exists in the current market. No one has challenged the high temperature heat pipe to transfer heat energy from magma to the power plant.

    Let’s take a look at the magma en...
