Crawling Toward Warp Drive
16 September 2004: A traveling-wave engine to power deep space travel, LANL
“A University of California scientist working at Los Alamos National Laboratory and researchers from Northrop Grumman Space Technology have developed a novel method for generating electrical power for deep-space travel using sound waves. The traveling-wave thermoacoustic electric generator has the potential to power space probes to the furthest reaches of the Universe.”
