The spark of commercial fusion
Inside the reactor arena
Fueling the future star
From lab to lightbulb
007skaty Extracting deuterium, a heavy hydrogen isotope with one proton and neutron making up 0.015% of oceans, provides cheap fuel for commercial fusion.
007skaty Heavy-water fission reactors produce the world's tiny supply of scarce tritium.
007skaty Steer mining rovers across the moon to discover how helium-3 powers clean fusion energy.
Ocean power: A single gallon of seawater contains enough deuterium fuel to produce the same energy as burning 300 gallons of gasoline.
A rare radioactive isotope of hydrogen with one proton and two neutrons in its nucleus. In 2026, South Korea's KSTAR reactor utilized tungsten walls to prevent retention of this scarce fuel.
007skaty Seawater extraction provides the primary heavy hydrogen fuel for nuclear fusion reactors.
What metal is used in reactor blankets to "breed" tritium when struck by fusion neutrons?
What is the radioactive half-life of tritium, the scarce hydrogen isotope used in fusion?
What is the main engineering benefit of fusing deuterium with helium-3 instead of tritium?
