In Fusion reactions: 1 liter of deuterium = 16 kT TNT. (16,000 X 4.183 = 66,928 GJ) In an Anti-Matter Reactor: 1 liter deuterium + 1 liter anti-deuteride = 8,000 kT TNT. (4,000 kT TNT if the other 50% of the energy is used to reproduce 1 liter of anti-deuteride). The Colony had a total of 80,000 liters of Deuterium, of which 2,000 liters were eventually given to Enterprise. Enterprise now has an additional 16,000 MT TNT (67 Billion GJ) worth of power at the end of this episode!

The Klingon tanker vessel seen in this episode, appears again later in the show as the D5 battle cruiser.
