Reflect Orbital is building prototypes satellite mirrors to reflect Sunlight to earth at night. Their primary target seems to be Solar panel parks, which could continue energy production during dark hours. However, you can also reserve a spot of sunshine anywhere in the world. Delivery promised Q4 2025.
Some technical debunking of this idea:
One calculation which clearly is missing from the startup proposal, is the immense spread of energy, leaving way less than a watt per square meter on ground from their 10x10m satellite mirror, which is already a challenge to put up to the space. So not really feasible.
Another, more interesting, but also less convincing, is that such satellites would burn our eyes. Not so sure if that is correct.. especially given that super low energy reach on the ground.
If you prefer more “infotainment” style of debunking, there is also a video by David L. Jones: https://www.youtube.com/watch?v=lkjyeI0ykGM
