William Robinson writes "Scientists have found way to use X-Ray Lasers to create supercharged particles. The specific tuning of the laser's properties can cause atoms and molecules to resonate. The resonance excites the atoms and causes them to shake off electrons at a rate that otherwise would require higher energies. This could be used to create highly charged plasma."
... though his invention worked superbly -- his theory was a crock of sewage
from beginning to end.
