Here's an excerpt from an upcoming chapter of my hard science fiction novel Flashover. I was wondering if this is plausible. I'm sure I must have made a mistake somewhere, and I was hoping that someone would kindly point it out. Remember the song Lasso the Moon? The capsule would actually lasso the moon, and pull. An antimatter production complex was nestled deep within, where billions of nanometric particle accelerators worked in tandem to produce the dangerous particles from hydrogen. The antimatter was then guided down the neck of a magnetic bottle and into the reaction chamber. Encased in a superalloy shell, the reaction chamber received normal hydrogen and antimatter, and they annihilated on contact into torrents of gamma rays and pions. The superalloy shell absorbed the intense radiation and quickly heated up, exchanging the thermal energy with a reservoir of cool hydrogen gas constantly pumped around it, and gradually cooling down while the heat exchange quickly turned the hydrogen into plasma. Once the outer chamber was full of sustained plasma, antimatter production would slow down, and the process would come to a halt. When needed, the plasma would be pumped out and fed into another set of nanometric particle accelerators, where it was accelerated to relativistic speeds and collided with more plasma. The resulting annihilation of plasmons released free gravitons that were instantly captured by artificial atoms. The ‘charged’ artificial atoms were then transported through magnetic channels to storage chambers for later use. To generate momentum, the capsule would transfer the artificial atoms to its surface using magnetic channels, where a directional microwave laser would release and guide the gravitons along the desired vector. The gravitons instantly latched to the closest gravity well in that direction, no matter how far, and pulled. The artificial atoms gravitated towards the target, but the containment field kept them in place, creating drag against the substructure. This would cause the entire capsule to move in that direction a fraction of a micron. The cumulative effect of performing the process using trillions of charged artificial atoms at once would produce massive lift in atmosphere, and would do much more in space. It wasn’t exactly a classical science fiction tractor-beam, but it was close enough.
