Imagine a renewable energy source so dense, a cup full could vapourize all the oceans on Earth! While this idea sounds even too bold for Star Trek, it is one possible consequence of the zero-point radiation field (ZPF) [1]. The ZPF is a uniform photon flux which permeates the entire Universe, existing even in total vacuum. It is not casually detected because the ZPF exists everywhere uniformly; perceiving it would be like a fish perceiving the water it swims in. Although the existence of ZPF is widely known and accepted by most physicists, the implications of the field and its role in the universe remain a matter of speculation. Physicists have identified four technologies the ZPF may yield: tapping ZPF energy, manipulating inertia, altering gravitation, and generating forces (propulsion). All four technologies have theoretical merit, and with expanded research and scientific attention, all four will likely be achieved.
