Nvidia has revealed a surprising partnership with an agricultural robotics company whose flagship product deals out instant laser death to fields full of weeds. The awe-inspiring Carbon Robotics LaserWeeder G2 packs in 24 high power lasers and 24 Nvidia GPUs to facilitate its claimed “10,000 weeds per minute” zapping performance. That's equivalent to 600,000 weeds per hour, or 167 weeds per second.
