China is planning to set massive solar power station in the sky by 2050. The scientists behind the vision mentioned that the solar power station would be bigger than the International Space Station (ISS) and would be built 36,000 kilometers above the ground.

The advocate for the station will be a 93-year-old academician of the Chinese Academy of Sciences named Wang Xiji. He is also an International Academy of Astronautics member and has devoted over 50 years to space technology research.

According to Wang, the huge solar power station is meant to solve entire energy crisis and will also save the planet from greenhouse gases and pollution.

However, the project is too huge and is surpassing the known mega-projects like the US Apollo project or the US-Russian joint project, the ISS.

The solar power station will be so huge that it may look like a super spacecraft on a geosynchronous orbit with its solar panels extending more than 6 kilometers in length each.

Scientists explained that the energy stored by the solar panels will be converted to microwaves or lasers and transmitted to a collector on Earth.

The other factor is weight of the space power station, which would be in the range of 10,000 tons. With such weight, an asteroid would be required to carry it into space.

Wang said, "We need a cheap heavy-lift launch vehicle. We also need to make very thin and light solar panels. The weight of the panel must be less than 200 grams per square meter".

He added that when space solar energy would become the main energy, people will no longer worry about smog or the greenhouse effect.
