Actually, you may be on to something. According to Wikipedia, Tritium is worth $30,000 per gram [1]. I can only assume that we can separate super-heavy water (T20) from regular water since we can separate heavy water (D20) from regular water. I don't know if $30K per gram is enough to cover the separation cost, but it seems like it might...
