SBSP: The Global Space Based Solar Power Race

China, though, is set to complete solar power generation and transmission tests at different orbital altitudes before building a station. The country plans to conduct a ''space high voltage transfer and wireless power transmission experiment''. This will occur in low Earth orbit in 2028, according to the China Academy of Space Technology (CAST).

A Sun that Never Sets

This concept has a few key advantages against "traditional" orbital solar designs: Power satellites will necessarily degrade over time. And contrary to solar panels on Earth, there is for now no realistic path to recycling, meaning that expensive and complex machinery are fully wasted at the end of their useful life.
