Hi, Given that it can't have come from deep space, it must have been created locally. Since nothing local is capable of generating such high energy fundamental particles, a small piece of plasma from the Sun, rather than a single particle, seems probable.
Cosmic rays are detected with multiple detectors all being triggered at the same time, and the assumption is made that the concurrent arrival of multiple lower energy particles is too unlikely. However the Sun emits bits of plasma frequently, so it's not inconceivable that a tiny plasma cloud arrives all at the same time. In short the high energy is due to multiple particles arriving concurrently, not due to a single high energy particle. Buy electric cars and recharge them from solar panels on your roof.
