... just make sure you don't light the grass or your neighbor's house on fire

What if my neighbors are ants?

(I've never actually used a magnifying glass on ants and I don't plan to start, it's just the trope)

I follow this person already for a while, very interesting things he come up with

Regarding solar electricity: does that mean to mirror the sunlight to a solar panel? If so: ignoring, that one would constantly need to adapt the mirror's position, I think I also read somewhere that solar panels decrease efficiency with heat. So my question is: could one increase solar panel output by bundling light or would heat related inefficiency cancel that out?

I think if the mirrors are used to boost the solar panel during times of the day/year when the sun angle is not optimal, it shouldn't be an issue.
