"First, the main problem is one of energy. In the same way that a car needs gasoline, a time machine needs to have fabulous amounts of energy. One either has to harness the power of a star, or to find something called “exotic” matter (which falls up, rather than down) or find a source of negative energy. (Physicists once thought that negative energy was impossible. But tiny amounts of negative energy have been experimentally verified for something called the Casimir effect, i.e. the energy created by two parallel plates). All of these are exceedingly difficult to obtain in large quantities, at least for several more centuries!"

"According to Bob Lazar, the reactor provides energy to the ship and to the gravity amplifiers by a matter anti-matter reaction. The square shaped housing below was a type of particle cyclotron accelerator that provides the protons for reacting with Element 115. A detailed physical description of the Matter Anti-Matter Reactor operation is provided in Jon Farhat’s BobLazar.com Website (this Website is a pay site). The protons are directed into the fuel housing through the guide tube shown on the left side of the reactor housing seen in the Figure 4 photo. When Element 115 is bombarded with protons, it becomes Element 116. Element 116 is unstable and gives up anti-protons. The anti-protons are directed downward from the wedge and annihilate when they come in contact with protons and produce energy. Each proton/anti-proton annhiliation reaction generates 1,862 Million Electron Volts (MeV) of energy. One Uraninum-235 fissioning (splitting) in a Nuclear Reactor generates about 200 MeV of energy for comparison purposes. That energy is directly converted into electrical energy through thermo-electric generators that are also located below the reactor in the square housing. There is no measurable gamma, neutron, alpha, or beta radiation emitted from this reactor. It poses no danger to the occupants of the craft."

"Element 115 serves not only as a generator of the Gravity A wave but also as the fuel for the matter/antimatter reactor that powers the rest of the flying saucer."

“The propulsion system is a gravity propulsion system and the power source is an antimatter reactor,” Lazar told Knapp during the original interview. “This technology doesn’t exist at all.”
