Lattice confinement fusion

Lattice confinement fusion (LCF) is a type of nuclear fusion in which deuteron-saturated metals are exposed to high energy photons or ion beams avoiding the confined high-temperature plasmas used in other methods of fusion. == History == In 2020, a team of NASA researchers seeking a new energy source for deep-space exploration missions published the first paper describing a method for triggering nuclear fusion in the space between the atoms of a metal solid, an example of screened fusion.
