Just turning some mirrors would require a lot less. C.f. SmartFlower, that powers its own motors to stay aligned with the sun. | |
| Jun 2, 2023 at 14:52 | comment | added | Matthieu M. | I agree with your analysis (minuscule and self-powered). I'm just not sure why the OP specified "powerless" -- if they have any odd reasons. | |
| Jun 2, 2023 at 14:39 | comment | added | MichaelK | @MatthieuM. I am applying the assumption that OP meant that the main source of the light was not something that needs power. That the infrastructure of the light source is powered and controlled, I would assume being quite acceptable, since that power requirement would be minuscule in comparison to trying to power the light itself. And in any case, it would be a sinch to make this into a self-powering/self-regulating system, using the incoming sunlight to power the movement of the mirror array, either through photovoltaics or sealed pneumatics (such systems exist today). | |
