In our hypothesis, we stated that the distillation would be the more energy efficient way to produce deuterium depleted water. However, this was not the case as the electrolysis method was much more energy efficient. In our experiment, we performed two tests of distillation, and two tests of electrolysis, combined into one sample. The distillation method used 16468.96552 joules average for every milliliter of deuterium depleted water, while in comparison, the electrolysis method used only 19.9431812 joules per milliliters produced. This is an impressive contrast and we believe that this is because much of the energy was lost through the hot plate. Moreover, electrolysis removed 0.01% more deuterium from the water that distillation. Therefore, our hypothesis was proven completely wrong and electrolysis is in fact, the more efficient method of deuterium depletion for our experimental setup.
