China's Big Plan: A Giant Solar Station in Space

ChinaThu Jan 16 2025
Harnessing solar power without the Earth's atmosphere getting in the way. That's what China is planning with its ambitious project to build a massive power station in space. This isn't just any power station; it's like moving the Three Gorges Dam into orbit, about 36, 000 km above the Earth's surface. The idea isn't new, but China is taking a big step forward with its Long March-9 rocket. This rocket can carry heavy loads into space, making it perfect for building the solar power station. It's also the same rocket that China plans to use for its moon missions. One of the biggest challenges is getting all the parts into space. China's rocket will help with that. Once up there, the solar panels will collect more energy than they would on Earth, and they'll be able to move around, always facing the sun. The energy collected will be sent back to Earth wirelessly, using high-energy radio waves. This might sound like science fiction, but it's a real possibility. In fact, engineers at Caltech have already done it on a small scale. The goal is to produce a lot of power. How much? Enough to match what we get from oil in a year. That's a lot of energy! But China isn't the only one with this idea. Iceland and a UK company, Space Solar, are also working on a space solar array. They plan to power up to 3, 000 homes by 2030. The big question is how well the energy transfer will work. It's been done before, but not on this scale. China will need to make sure the power gets to Earth efficiently. This project is still in the early stages. We don't know when it will be finished. But it's an exciting idea that could change how we think about renewable energy.

questions

    Will astronauts be able to use the space station's power to run their coffee makers?
    If China builds a giant power station in space, will they get a frequent flyer discount on trips to the moon?
    Could the space station be used for military purposes, rather than just providing energy?
