Deuterium concentration in seawater
WebFortunately, deuterium is common. About 1 out of every 5,000 hydrogen atoms in seawater is in the form of deuterium. This means our oceans contain many tons of deuterium. If fusion power becomes a reality, just one gallon of seawater could produce as much energy as 300 gallons of gasoline. WebAbstract. THE deuterium content of natural waters has hitherto been determined either by accurate density measurements or by a mass spectrometer, absolute values being …
