Perpetual Motion Controversy
See also: Mass–energy equivalence and First law of thermodynamicsNewman claims that his device derives its power by converting a small fraction of the mass in the copper coils into energy, and that it is therefore not a perpetual motion machine. Many scientists don't think this theory is correct, and still classify it as "just another impossible perpetual motion machine". Skeptics argue that regardless of the exact mode of operation, if the output power is higher than the required input electrical power, the device should be capable of running "closed-loop", producing excess power without external batteries. Such operation has never been demonstrated.

Famous quotes containing the words perpetual, motion and/or controversy:
“Admiration is a very short-lived passion that immediately decays upon growing familiar with its object, unless it be still fed with fresh discoveries, and kept alive by a new perpetual succession of miracles rising up to its view.”
—Joseph Addison (1672–1719)
“The moments of the past do not remain still; they retain in our memory the motion which drew them towards the future, towards a future which has itself become the past, and draw us on in their train.”
—Marcel Proust (1871–1922)
“Ours was a highly activist administration, with a lot of controversy involved ... but I’m not sure that it would be inconsistent with my own political nature to do it differently if I had it to do all over again.”
—Jimmy Carter (James Earl Carter, Jr.)
