Universal solar energy system $ 21 billion

Japan is preparing to develop a 2 trillion yen solar energy project (approximately 21 billion USD) to accumulate electrical energy from the universe in the form of microwaves or laser beams providing 300,000 Households in Japan within 3 decades.

The project is undertaken by a team of 16 companies including Mitsubishi Heavy Industries, the goal is to develop technology to accumulate electricity for the Earth in four years. They believe that when the fuel is depleted, solar projects on Earth's orbit will be the end, providing considerable energy in the future, Kensuke Kanekiyo from the Japan Energy Economics Institute said.

Energy stations are expected to produce around 1GW of electricity from 4km2 of solar panels, enough to meet the energy needs of 300,000 Japanese households with current energy consumption. This huge energy battery will be in orbit about 36,000 kilometers from the Earth's surface so it will not be affected by the weather and capable of producing electricity continuously.

The NASA Center of America has conducted research on the potential of the solar energy system over the past few decades and has spent about $ 80 billion on research. NASA and other governmental organizations estimate the cost of electricity provided by a solar-powered solar cell at about $ 1 billion / 1MW of electricity. This cost is considered too expensive.

Japan realized that the cost of building a solar power station on orbit would make it impossible for households to access this power source at the present time. And the promotion of this battery could not be carried out at current prices. Therefore, the Japan Federation of Unions must find a way to reduce the cost of this project.

Koji Umehara, director of the Japanese Space Development and Use Department, said that with the unilateral missile launch worth 10 billion yen, the cost of the space station would be about 2 trillion yen, making it Power supply charges are extraordinarily increased.

The first step in the journey to bring the project to success is to launch a satellite that matches the solar panel in 2015. The battery will generate electricity to the ground.

JAXA, the Japanese aerospace research agency estimates that the solar energy system will be operational by around 2030.
