To quote in part:
To Terry Kammash, going to the stars is not sci-fi stuff. In the new millennium, the nuclear engineer envisions missions to Alpha Centauri, closest star to our solar system. In just the next 20 to 25 years, he predicts spacecraft will reach one milepost on the route, the Oort Cloud, a debris-filled comet belt 932 billion miles away. And he’s betting the missions will use fusion, the basic energy source of stars themselves.
