My favorite word of the month is futile!
According to Wikipedia (http://en.m.wikipedia.org/wiki/Futile_cycle)
“A futile cycle, also known as a substrate cycle, occurs when two metabolic pathways run simultaneously in opposite directions and have no overall effect other than to dissipate energy in the form of heat.”
Thus the word futile. Two opposing forces cancel each other and the result is heat or futile. Heat in a non biochemical concept would be translated into frustration, in other words wasted energy, obviously without any result.
