Zero-point energy, ZPE, refers to energy that exists even at absolute zero. One form of this rises from quantum field theory, which cites a universe composed of continuous fluctuating fields formed from a huge amount of energy that we cannot see. Some argue this is an artifact of mathematics, not a real thing. Others say that, if it is real, it is in equilibrium & entropy principles will not permit us to tap it. Recently, ZPE has become fodder for SciFi novel & screenplay writers as a source of limitless “free” energy. What is SciFi & what is real? What’s the true potential of ZPE & how close might we be to realizing it? With a focus on the science & engineering technology, lecture attempts to separate fact from fiction. Presented by Capt. Mark McDonagh, USN/ret., a physicist with 12 years’ experience at the Naval War College, on the National Security Decision Making Game staff.
