Much media attention has been paid to the sea of energy that pervades all of space. It just happens to be the biggest sea of energy that is known to exist and we're floating inside it. Not only is it big but its energy is estimated to exceed nuclear energy densities, so even a small piece of it is worth its weight in gold. What is it? Many people are not sure what zero point energy (ZPE) is. Most agree that virtual particle fluctuation contributes to it and van der Waals forces don't explain everything. Does it offer a source of unlimited, free energy for homes, cars, and space travel? Depending on who we talk to, ZPE can do everything and ZPE can do nothing useful. How can the energy be converted to a usable form? What are the basic explanations of ZPE and the new discoveries, which have hit Physical Review Letters, Science, Scientific American, and the New York Times? Why is ZPE implicated in the latest confirmation of "cosmological antigravity"? Can the Casimir effect be a source of energy? This presentati
