He had since turned his attention to the problem of fusion in high-pressure environments, believing it could explain the fact that the interior temperature of the Earth was hotter than could be explained without nuclear reactions, and by unusually high concentrations of helium-3 around volcanoes that implied some sort of nuclear reaction within.
Muon-catalyzed fusion is a well established and reproducible fusion process that occurs at ordinary temperatures.
Pyroelectric fusion was reported in April 2005 by a team at UCLA.

Nuclear fusion of heavy elements occurs in the extreme conditions of supernova explosions.
The reaction cross section σ is a measure of the probability of a fusion reaction as a function of the relative velocity of the two reactant nuclei.
The net result is the fusion of four protons into one alpha particle, with the release of two positrons, two neutrinos, and energy, but several individual reactions are involved, depending on the mass of the star.

The activation energy for fusion is so high because the protons in each nucleus will tend to strongly repel one another, as they each have the same positive charge.
The box is a simplification of the general magnetic confinement fusion scheme in which a high energy ionized gas (a plasma) is confined in a magnetic field.
The stated goals for a commercial fusion power station design are that the amount of radioactive waste produced will be hundreds of times less than that of a fission reactor, that it will produce no long-lived radioactive waste, and that it will be impossible for any fusion reactor to undergo a large-scale runaway chain reaction.

 Cold fusion - Wikipedia, the free encyclopedia
Such cold fusion was initially reported by Martin Fleischmann and Stanley Pons at the University of Utah in March of 1989.
Another form of cold fusion is muon-catalyzed fusion; unfortunately, the muons it uses require too much energy to create and have too short of a half-life to make the process practical for energy generation.
Cold fusion researchers say that it could have a substantial economic impact, with advantages over plasma fusion (which has also not yet been developed for practical application) because it produces little ionizing radiation and can be scaled to small devices.

The term "cold fusion" was coined by Dr Paul Palmer of Brigham Young University in 1986 in an investigation of "geo-fusion", or the possible existence of fusion in a planetary core.
He had since turned his attention to the problem of fusion in high-pressure environments, believing that fusion in the metallic hydrogen core of Jupiter might be responsible for the higher than normal temperatures of that planet.
The scientists used a pyroelectric crystal heated from −30 to 45 degrees Fahrenheit (from −34 to 7 °C) combined with a tungsten needle to produce an electric field of about 25 gigavolts per meter to ionize and accelerate deuterium nuclei into an erbium deuteride target.

 Mineralogy Notes
Further, gravitational instabilities within each galaxy caused further collapse of the gas into primitive stars where the very high temperatures caused by gravitational collapse ignited the fires of thermonuclear fusion in which the nuclei of the primitive light elements combined to form heavier elements.
Before temperatures cooled sufficiently in the inner solar system so that the most volatile elements (H, C, N, and the noble gases) could condense, H fusion in the sun ignited and blew these elements to the outer solar system where they are enriched in the outer planets, Jupiter, Saturn, Uranus, and Neptune.
The Earth accreted from these early solid particles called chondrules, and these refractory elements are enriched in the Earth relative to their abundance in the Sun.
