By the way, this reminds me of Dr. Daniel Sheehan's work in challenging the second "law" of thermodynamics. Dr. Sheehan is a physics professor from the University of San Diego and developed a paint / coating that was able to absorb essentially ALL energy in its surroundings. It is able to consume any and all heat energy and convert it to electricity and thus cools the surroundings. An object traveling at extremely high velocities in water (imagine how a Tuna can travel so quickly that they can burn themselves from friction) would create incredible friction and heat (unless it is able to create a field around it to eliminate such friction), that the heat would need to be dissipated. Dr. Sheehan's technology could effectively take advantage of the heat/friction and simply produce MORE energy and thus propel such an object even more rapidly. Such a device would be an incredible source of usable energy.
Disc 8 from "Energy From The Vacuum" was fascinating in this regard (but apparently the site is now dead following Tom Bearden's sad passing this past winter):
