Explaining the mechanism of the combined-cycle power stations, Arai said that "Thermal energy released as a result of the combustion process powers the turbine that generates heat, which, in turn, is also used to power the turbine's rotation."

According to Arai, the new technology cuts the release of toxic waste materials by 40-50 percent.

"We could use the old thermal power stations while simultaneously creating power plants that would run on liquefied natural gas. In this sense, we really hope for the supply of gas from Russia," Arai added.

Arai was born in the Fukushima prefecture, which was hit by a 9.0-magnitude earthquake and a subsequent tsunami in March 2011 that caused a partial meltdown of three of the nuclear reactors at the Fukushima Daiichi nuclear power plant.

The incident, which was the world's worst nuclear disaster since the Chernobyl catastrophe of 1986, is final proof of the fact that nuclear power plants are not safe, Arai believes.

"I stand for a "subnuclear society." It will change the structure of energy consumption and production and it will not need nuclear power plants. A society that will surpass the need for nuclear energy. It will not make the poor live in a dangerous environment for the sake of the wellbeing of large cities," Arai said, noting that people in Japan"s poorer regions agree to the construction of nuclear power plants out of necessity.

Japanese families could also produce their own energy at energy farms, or ene-farms, which are a combined system of extracting energy using heat and gas, existing only in Japan, Arai explained.
