"The primary attraction [of writing sf] is the sheer pleasure of creating something from whole cloth."

| Beam-Powered Propulsion | ||
| Using a powerful energy source as motive power for a projectile. |
| Then Bill, with his eye at a telescope, saw a little spark of purple light appear beside the blue globe. A tiny, bright point of violet-red fire, with a white line running from it, back to the center of the sphere. The purple spark grew, the white line lengthened. Abruptly, the newspaperman realized that the purple was an object hurtling toward him with incredible speed.
Even as the realization burst upon him, the spark became visible as a little red-blue sphere, brightly luminous. A white beam shone behind it, seemed to push it with ever-increasing velocity. The purple globe shot past, vanished. The white ray snapped out... "A solid projectile !" Brand cried. "And driven on the positive ray! Our experts have tried it, but the ray always exploded the shell..." |
