Electro gravitic technology?
Sounds like something out of a sci-fi film!
Google reliably tells me that electrofravitic is a sinonym for antigravity and involves the known effect that a capacitor will tend to move towards the positively charged plate.
Apparently if you charge your leading edge to a potential of +MV, and your trailing edge to -MV then you get a strong forward propulsive force.
After that it all gets a bit "Douglas Adams" with talk of synthesis of an element 115 imaginatively named "ununpentium" with "a gravity Alpha wave which extends outside the atom and can thus be amplified and directed to distort large portions of space time"
Beam me up Scotty!!!
