I remember a short fiction piece in which a South American football team gave out large mirrored programs to all their fans in attendance at the game. When the eternally corrupt referee made a bad call, they all focused the reflection of the sun on the official and he went up in a puff of smoke.

Wouldn't it be funny if these 100 women with mirrors did the same thing! Sunlight is 1 kilowatt per square meter, if the sun is shining. Say 90 kilowatts concentrated in 1 square meter of Trump's backside?
