This is the big USEF japan consortium of companies along with JAXA developing SPS tech, with a nominal target goal of 2030, but utterly not addressing the spacelift cost issue

Interesting arguement that a SPS demonstrator can be built now with COTS/near COTS hardware, taking advantage of mass production of terrestrial products to reduce costs. The primary tricks being accepting losses in efficiency and overcoming it by reducing system mass, so the actual W/Kg is still higher. Thin film solar, carbon fiber booms, thin film inflatable reflectors and optics, power equipment mass reductions, and lower cost space access (SpaceX) are the COTS components that make at least the demonstrator possible. There is the interesting talk of making sure most technology/products are dual use, such as wireless power transmission to HALE LTA UAV sensor blimps to offload payload power requirements.
