China is not the only country looking into the technology. Researchers at the California Institute of Technology launched a space solar program after a $US100 million grant in 2013. Researchers in India, Russia, the UK and France are also exploring possibilities and Japan is particularly advanced in the field, according to Xidian.
Individual components of solar-from-space technology have been tested before. But the Chinese researchers are the first to successfully test a full-system model, Xidian said.
