AR-15

Most of the AI facial recognition cameras in the USA are from Flock and use small solar panels to keep the system battery charged. I've noticed that when I run small computers off small batteries and small solar panels even a bit of bird poop on the panel eventually causes the computer to run out of power. Bird poop, or bird poop simulants (like milk powder, black pepper, corn starch, water, wey powder) are non-destructive to solar panels or anyone's property. Sure would be cool if the birds would start helping.
