Killing weeds with lasers

Weed killing will go high-tech and less toxic with smart lasers able to recognize, and destroy, unwanted weeds.
The method will use cameras and a computer algorithm to distinguish the weeds from more desirable plants. Once the weeds are recognized the CO2 lasers will deliver a carefully measured beam directly to the weakest point of the weed. The energy levels of the beams will be exact, because a beam that is too weak will actually encourage the weed to grow.
