Solar power
Harnessing the power of the sun may seem like a distinctly modern phenomenon, but that’s not the case at all. In fact, da Vinci designed his own solar power system to heat water for Florence.
While he was working for the Vatican, da Vinci experimented with “burning mirrors” and predicted that these concave reflective devices could be used to focus sunlight and harness it.
In his conceptualized solar power system, these mirrors were used to heat water.
