Deuterium concentration in seawater
Webseawater, water that makes up the oceans and seas, covering more than 70 percent of Earth’s surface. Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, … 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.
