Ahh, the old devil's pogo stick... The thermonuclear Orion could, on paper, achieve up to 10% the speed of light on an interstellar trajectory at least for a small payload. It's possible that it could send a probe to the Centauri system that would arrive in 40-50 years, short enough to be feasible on human time scales.
