Solar-Powered NASCAR Track Mows Grass With Sheep

Infineon Raceway in Sonoma, California, has already hit the pages of TreeHugger for hosting insanely fast electric motorbikes. But while the idea of "green" motor racing may still seem somewhat of an oxymoron, Infineon is working hard to prove otherwise. Not only have they just unveiled a solar array big enough to supply 41% of the circuit's electricity demand, and launched an ultra-efficient LED billboard, they've also taken to mowing their extensive grass with sheep.
