We can take into account that no exhaust pipes or mufflers were found at Roswell. In fact, the propulsion system of the downed disk was a complete mystery.
Through other sources we can see that beamships (ufo's) operate with a variety of systems, most of which use energy abundant throughout the universe. Most agree that source is the tachyon.
Compare this to our funky cars with their need for gasoline. Internal combustion engines have been in use for well over 100 years. They're nasty, inefficient, and require...uh...
fuel.
But wait: WE require fuel, too, don't we? Yes, now that I think of it, we do. Yet the ascension indicates that we will change our mode of sustenance to LIGHT at some point of our transformation.
One might do well to consider the caterpillar, who bulks up before entering the cocoon, emerging a butterfly with a completely different structure, and gentler nutrition requirement.
