mdlbearAnyone who believes that the US patent system is not completely broken needs to take a look at United States Patent 6,960,975: Space vehicle propelled by the pressure of inflationary vacuum state.
A space vehicle propelled by the pressure of inflationary vacuum state is provided comprising a hollow superconductive shield, an inner shield, a power source, a support structure, upper and lower means for generating an electromagnetic field, and a flux modulation controller. A cooled hollow superconductive shield is energized by an electromagnetic field resulting in the quantized vortices of lattice ions projecting a gravitomagnetic field that forms a spacetime curvature anomaly outside the space vehicle. The spacetime curvature imbalance, the spacetime curvature being the same as gravity, provides for the space vehicle's propulsion. The space vehicle, surrounded by the spacetime anomaly, may move at a speed approaching the light-speed characteristic for the modified locale.
I would like to point out that this is an issued patent, not merely a published application, and that the application was filed March 14, 2005 -- which is amazingly fast work for the US patent office.
