Researchers say that if this technology is fully realized and deployed on a large scale, it will completely change the rules of the game in the energy industry p> < p > < p > Harry Atwater, Professor of Applied Physics and materials science at California Institute of technology and SSPP researcher, said: "solar energy is the most abundant energy in the world, but there is not much sunlight on the earth's surface. The ambitious SSPP project aims to provide a transformative approach to large-scale solar energy collection. " p> < p > Irvine chairman Bren said in a statement: "for many years, I have been studying how to use space solar energy. I am interested in supporting scientists at the California Institute of technology because I believe that using the natural power of the sun can benefit everyone. " p> < p > SSPP project team members stated that Bren did not enjoy financial benefits in SSPP or any technology it developed. SSPP has developed a technology demonstration prototype that converts sunlight into RF microwave energy and then wirelessly transmits it back to earth in the form of a steerable beam p> < p > the representative of Caltech said that the research team plans to conduct the first space test of SSPP technology in early 2023( (small)
