Long a favorite of Hollywood screen writers and movie makers is the energy weapon. These devices, referred to in the trade as EMPs or Electromagnetic Pulse weapons, are much closer to production than you think. All of the major economies are actively developing the technology; for example, Boeing’s EMP drone,CHAMP, is capable of flying over an AO and disrupt communications and systems (routers, servers, gateways, etc.). The Israelis have also developed an EMP, Netline’s Portable Jammer Packs. Its about 3 times the size of the M67 fragmentation grenade, which when planted and activated will disrupt all forms of communications.
What makes EMPs such a desirable tool is that they can be used “without incurring the loss of human life.” I place that in quotes because eukaryotes, which is the cellular organization that makes up human life, relies on a difference in electrical potential between the cellular milieu and the cell membrane. It is conceivable that a more highly developed EMP will shut down cellular activity. So, you’ll be happy to know that we may not have to scrape your intestines off a wall; instead we’ll simply find you with the ON/OFF switch in the OFF position.
If EMPs enter the scene in significant numbers you will see an acceleration in light based technologies. Light is impervious to electromagnetic artifacts. Imagine a computer’s processor operating with a photon rather than an electron, or an I/O buss running on fiber optics. We live in exciting times.
