Did a story that had a rebar dart thrower. A generator driving a large electric motor that drives two truck wheels just barely touching. The rebar dart is edged into the tires from an angle iron. The dart shoots out at high speed. Mounted on a trailer or in the back of a pickup, with a elevation and traverse mechanism a spray of darts can be launched in just a few seconds.
