COLLEGE STATION, Wednesday, February 26, 2003 -- Marlan Scully, the Texas A&M University professor who applied quantum physics to the automotive engine and came up with a design that emits laser beams instead of exhaust, has been tinkering under the hood again. This time, he's sized up the perfect engine -- and improved it.

Scully, known as the "Quantum Cowboy" for his innovations in quantum physics and his Franklin Society prize-winning research into beef cattle production, has invented a theoretical design more efficient than the Carnot engine, which had stood for nearly two centuries as the standard for efficiency -- an engine so ideal it exists only in theory.

In an article published this month in Science, Scully reveals a design that extends it. Scully's design employs lasers, mirrors and a concept known as "quantum coherence" to drive a piston with less wasted energy than in the Carnot model.

In Scully's engine, a quantum heat bath supplies the power: beams of hot atoms produce radiation whose pressure drives a piston. Scully likens the atoms to coal and the radiation to steam that drove early railroad engines.

Scully, a member of the National Academy of Sciences who holds joint appointments in physics and electrical engineering, is world-renowned for his work. But even though he and his collaborators have improved the engine that had been considered perfect, Scully makes clear that they have not rewritten the laws of physics -- the second law of thermodynamics is not violated, he says, and perpetual motion is still a dream.

The new engine model follows Scully's recent invention of the "quantum afterburner," designed to capture energy from a car's exhaust, thus improving the efficiency of a classical four-stroke engine. The quantum afterburner uses a process that drains heat from the heat-engine gases and converts it into laser light.
