Steam as Trackside Weed Killer

Jump to Comments

Dave Polster has come up with a way to remove weeds from a railbed without using herbicides, the Esquimault News reports: steam! “Based on a UBC scientist’s study [that] determined that high-temperature steam was an effective method for killing weeds, Polster and others coddled together leftover items to create a prototype machine that put the theory to work,” says the paper. “Upgrades and improvements yielded a mobile, rail-based machine that created a veil of low-pressure, high-temperature (425 degree Celsius) steam that instantly cooked plant tissues.”
