>In the patent for the HEEMFG, the technology is described as being able to create what is essentially a force field straight out of science fiction, one that could generate “an impenetrable defensive shield to sea and land as well as space-based military and civilian assets, protecting these assets from such threats as Anti-Ship Ballistic Missiles, Radar Evading Cruise Missiles, Top Attack for Main Battle Tanks (land and sea-based systems), as well as counteracting the effects of solar-induced Coronal Mass Ejections or defending critical military satellites in an ASAT [anti-satellite] role (space based system).”
