climb grades in excess of 10 per cent! The pulsed magnets induce reversed electric currents in the aluminium plates that form the track. The induced currents create their own magnetic fields that oppose those of the train. With the aid of optical sensors, the fields pulse "on" just as the magnets pass the midpoint of the plates and, by repulsion, propel the train forward. The Maglev technology works with this pulsed electricity to propel the train, minimising the amount of power needed. Pulsed energy, therefore, seems to produce more force per overall energy used than does continuous energy. For this reason, pulse technology is also being developed for several aviation uses and to confirm certain theories. Nuclear pulse technology has also been recently considered for NASA's new Orion spacecraft program, where it may require long-distance flights to take a new generation of astronauts to local planets in the next two decades. climb grades in excess of 10 per cent!

"Free Energy and "Over-Unity" Technologies The Lorentz force is a well-known force created by the interaction of a magnetic field and an electric current. Consequently, pulse technology can be used with electromagnetic energy. Such electromagnetic energy is now being considered by many "new-energy scientists” who are experimenting to create "over-unity" technologies as the key not only to extraterrestrial travel but also to "free-energy" technologies. So-called “over-unity" and "free-energy" devices do not create energy but, rather, convert existing, potential or usable energy, the source of which is unknown in today's science. According to inventors Thomas Bearden (www.cheniere.org), Stephen Patrick et al., who filed for a US patent on a "Motionless Electromagnetic Generator" (MEG) (US Patent 6,362,718, granted March 26, 2002), this technology is the right step forward towards such over- unity or free-energy technologies (see www.byronwine.com/files/MEG.pdf). In their abstract, they Over-Unity Measurement Guidelines Although many inventors and researchers are working to achieve such over-unity conditions, our close associate Patrick Bailey, PhD, a graduate of MIT and formerly a project manager with the Electric Power Research Institute (EPRI), warns the non-scientific observer to be very cautious. Dr Bailey claims that it is not so difficult to show a simple demonstration using the wrong equipment to exhibit a device that creates "more energy out than energy in". Over the last 25 years, Dr Bailey has examined and recorded with one of the authors (Dr J. J.) over 150 technologies of energy systems that have been claimed to have "over unity" performance or new "clean energy" processes. Dr Bailey affirms, after extensive investigation, that one must use a high-frequency digital oscilloscope to determine the true voltage, current, power and energy measured in such devices.
