To: Matmail: What are those beach ball-shaped things that are strung on high-voltage power lines, such as the lines that cross I-15 at Poway Road? They are so obvious and so seemingly without purpose that I imagine you must have received dozens of perplexed inquires about them already. Please humor me.... — Ed LaFrance, Poway
Strung-out balls rate a zero on the inquirymeter, Ed. Yours is a first. The key to the answer is right in your question — “so obvious.” Without the so-obvious orange/yellow/red plastic balls, the power lines would be nearly invisible against the bright blue sky. Consider the implications for low-flying aircraft.
