Fusion-fuel isotopes, deuterium and tritium
Also the required fusion-fuel isotopes, deuterium and tritium, are hard to produce. Deuterium exists in seawater in a highly diluted ratio so that it takes the processing of 600,000 tons of sea water to extract enough deuterium for one ton of fusion fuel that would, if the process was workable, power a one-gigawatt reactor for a year. In order to replicate the current electricity production by this process, 2,500 times as much water would have to be processed for the needed fuel each year. This would be a gigantic requirement, if not a prohibitive one.
