The true intensity of the blade comes from energy refracting crystals near the top of the handle. Finally, the focusing core channels the energy into a coherent shaft of light that is bent back upon itself creating the blade. Next up in our little tech double header, repulsorlifts. No, these aren't something that really ugly people put in their shoes to look taller. Repulsorlifts are a common antigravity drive system.
Many vehicles are dependent on repulsorlifts for terrestrial operation.
Examples include Luke Skywalker's landspeeder, the Rebel Snowspeeder, the Imperial Speederbike, and the commercially produced Swoop. Likewise, 'Lifts cannot function in space. The 'Lifts use a fusion generator to create an antigravity field that allows the vehicle to resist planetary gravity, much like positive and negative magnetic fields repulse one another. The altitude of the repulse depends on the strength of the field. I hope this helps make up for my lack of an entry last time.
