I'm curious about the feasibility of modulating light onto a solar panel. I feel it would not be feasible, except possibly onto a single panel at a time over a long time period. Just a gut feeling based off radio stuff (GPS).
- DoctorOetker 2y agoGPS can provide the coherent reference, if you mean transmitting signal (say sound) while the panel is illuminated by the sun theres youtube videos of people doing that, with a laser pointer, but in sunlight and without information theoretic justified modulation scheme. Nothing prevents the satellite to transmit the commands at night, if that feels more convincing to you. Ask yourself what is the active area of a photodiode in your TV/... ? What is the active area of your light-bucket on a roof?
- outsomnia 2y agoThis is just FUD.
- DoctorOetker 2y agoI'm not at all claiming this is happening, I'm claiming this is very feasible to do. Consider the aperture (area) of a camera or telescope, how many times can you fit this area into a domestic solar panel installation? If we are discussing the solar panel that powers your outdoor garden light, I don't suggest to apply the precautionary principle, but we are talking about products that sum up to a significant fraction of grid power generation.
