Road Hawk

摘要

Nap perin had been waiting on the side of the highway near his Alberta, Canada, home for more than hour when the tow truck finally pulled up. The driver looked at the stranded electronics technologist and his homebuilt electric trike and asked, "Ran out of juice, eh?" Pepin wasn't sure what the problem was, but he knew he still had plenty of charge. He had been tinkering with battery-powered three-wheelers since 2005, and by that point, late last year, he had spent hundreds of hours designing a battery pack to ensure that his vehicle, the Lithium Hawk, would never unexpectedly lose power.
