Reflect (Reflect Orbital) is building a fleet of low-cost, deployable reflective satellites in terminator orbits to illuminate commercial solar farms after sunset. They proved the concept with an 8x8 ft mylar mirror balloon demo, model composite ground spots made from ~100 satellites, and aim to mass-produce thousands of units while leveraging existing rockets to avoid prohibitive launch/program costs.
