The main fuels used in nuclear fusion devises are deuterium and tritium, both heavy isotopes of hydrogen. The Deuterium (D) – Tritium (T) reaction has the largest cross section (in other words, the ...

We’ve been sent this press release claiming a new kind of fusion reaction that works at small scales using an incredibly exotic fuel material: ultra-dense deuterium. We looked into it with an ...

Deuterium and tritium are the best candidates for fusion energy, as they have the highest fusion cross-section and the lowest ignition temperature. Deuterium is abundant in seawater, while tritium ...

Plans call for first-generation fusion reactors to use a mixture of deuterium and tritium — heavy types of hydrogen. In theory, with just a few grams of these reactants, it is possible to produce a ...
