Imagine a "rocket" that only uses electricity.

Have a ragtag group of physicists and engineers exploited a little-known feature of Einstein's equations to built a true propellant-less space drive that doesn't require reaction mass ... just electricity?

James Woodward, physics professor emeritus at Fullerton, thinks so. NASA has funded new research into it, and the result if successful would be the ultimate EV ... an electric vehicle that not only can propel a space ship to the planets and the stars, but also lift off out of gravity wells like Earth's.
