Archimedes agrees

They already do this fyi. Solar plants tend to use mirrors that concentrate light to heat water and turn a turbine instead of actual solar panels. Amazingly, iirc converting light into heat, the heat into steam, and then the steam into kinetic energy, is still more efficient than a normal photovoltaic cells.

And if you wanna go big you use liquid salt instead of boring old water.

Mythbusters used a lot of mirrors, and could not get it to work.

Sadly I believe they found adding more mirrors did not appreciably raise the temperature of the focal point. Diminishing returns and all. So unfortunately more mirrors is not the answer, more Lasers is!
