For concentrated solar polar, you need almost constant movement of the mirrors to keep tracking the sun well enough. So you need independent azimuth+elevation

For concentrated solar polar, you need almost constant movement of the mirrors to keep tracking the sun well enough.
So you need independent azimuth+elevation for each mirror.

There’s always a performance/cost target you’re trying to hit. Sometimes it’s not about performance at all costs and it’s ok to sacrifice some optimality to get a much cheaper solution. So while the mirrors are independently adjusted, the there’s a single motor robot on a rail that comes by and custom adjusts each mirror instead of having the mirrors self adjust locally at all times.
- fl7305 2y agoIt's an interesting idea, but I think you'll be surprised at how fast the sun moves. You can try it yourself. Put up a small mirror that reflects a sun spot on a surface. Clock how fast it moves a centimeter. Multiply that distance with how much further away a central tower would be.
