OK, then! I'm building my own nuclear reactor!!! First! you need deuterium!!!! Now, with this process, I'm already having a powerful motherfucker radioactive substance, to split around !!! So, how ? " You get say 10 gallons of water, you make electrolysis until you have say 1 liter left, because deuterium is heavier (my speculation) you end up with all the heavy water in the 1 liter, you do it again, again you have all the heavy water, again, again, again, again, and at one point you will start to actually hydrolize the heavy water rather than the regular water, when you do this you will get pure deuterium. Note that you will get very little deuterium from this water, you will need thousands of liters of water to make decent amounts of deuterium. "
