The Casimir effect governs interactions of matter with the energy that is present in a vacuum. Success in harnessing this force could someday help researchers develop low-friction ballistics and even levitating objects that defy gravity. For now, the U.S. Defense Department's Defense Advanced Research Projects Agency (DARPA) has launched a two-year, $10-million project encouraging scientists to work on ways to manipulate this quirk of quantum electrodynamics. Vacuums generally are thought to be voids, but Hendrik Casimir believed these pockets of nothing do indeed contain fluctuations of electromagnetic waves. He suggested [that] as the boundaries of a region of vacuum move, the variation in vacuum energy (also called zero-point energy) leads to the Casimir effect. Recent research done at Harvard University, Vrije University Amsterdam and elsewhere has proved Casimir correct and given some experimental underpinning to DARPA's request for research proposals.
Note: Debunkers of the new energy movement have long claimed that zero point energy is a theoretical construct which cannot have practical applications. This article shows that attitudes are now shifting. For lots more reliable information on what's still hidden from the public on the new energy front, click here.
