Scalar EM is the brainchild of Lt. Col. (retired) Thomas E. Bearden, a systems analyst and wargames specialist who has been advocating a view of electromagnetics which is based on the notion of a vast, unseen background of scalar energies (as opposed to vector energies) which underly all physical reality.
What electrical engineers work with today, claims Bearden, is a subset of a higher-topology EM. Bearden claims that the four "Maxwell's Equations" taught today in electrical engineering are actually an over-simplified subset of Maxwell's original work. The pruning was done by Oliver Heaviside in the late 19th century; Heaviside took Maxwell's original equations, written in Hamilton's quaternions (related to what we nowadays call spinors), and "simplified" them by lopping off the scalar part of the complex numbers, leaving the easy-to-work-with vector part intact-- which radio engineers loved. After all, the entire electronics industry as we know it grew out of the telephone/radio technologies of the early 1900's. Who can argue that the "vector" approach is inadequate?
Well, Bearden says that when Heaviside threw out the scalar part of the quaternionic EM equation, he unknowingly threw out the possibility of unifying gravitation with electromagnetism-- which has been a holy grail for scientists since Einstein himself wrestled with the problem. That's because the scalar part of the quaternion, according to Bearden, was the part that captured or modeled the "stress on the aether"-- which leads to curving/warping spacetime a la Einstein. Tom Bearden says we CAN unify gravity with EM, and convert back and forth between them, if we understand how vectors and scalars relate to one another and what the ramifications are.
Vector fields can evidently be assembled by properly interfering scalar potentials (predicted in 1903-4 by mathematician E.T. Whittaker and probably engineered by the Soviets).
Conversely, scalar fields can be created by destructively interfering vector fields, in a nonlinear medium. Varying the vector components rhythmically produces what Bearden calls "scalar waves". These ripples in spacetime are believed to induce a wavelike stress in the "aether"; this in turn leads to engineering the structure of pure space and/or mass in a localized area-- in other words, implementing General Relativity (spacetime curvature) on the lab bench!
Tom Bearden has gone on record, in several of his books published in the 1980's, to proclaim that the former Soviet Union had created a fantastic arsenal of mind-bending weaponry based on this scalar technology, which they called "energetics" and which Bearden claims was developed from certain discarded ideas originated by Nikola Tesla. Now that the Cold War is apparently over, we're not sure how Bearden views his previous assertions, but we note that he has turned his attention away from Soviet scalar weapons and toward the production of "free energy" from the vacuum of space, using the principles of optical phase conjugation, but in a more generalized mode.

Here is the point:
If Bearden is correct in his Scalar EM theory, then we can build devices which would enable us to alter gravity, time, inertia, and the apparent mass of an object. This of course has ENORMOUS implications for military applications, space-vehicle drives, time-travel, teleportation, paranormal phenomena, and just about every other area one can think of.
The Big Question is, Will the 21st century see the acceptance, development, and implementation of Bearden's ideas (in plain public view, mind you), or will Scalar EM be found to have been just another dead end?.... Do certain world governments have these devices NOW?... Bearden says at least "three other nations, not hostile to the U.S.," now possess Scalar technology.
