Power systems were a recurring subject this week in the technology world. Although many of them veered toward using solar energy, using delicious rays from the sun to juice up air conditioners, cell phones and watercraft, a couple went for the dark horses of wind power (on a bridge, no less) and even bottles of Coke. And for when your conventional power systems fail you, it's nice to know you can ride away on your electric motorcycle with a Stormtracker. The power… it feels… good.
