In typical hnews fashion people are ignoring the actual article and instead debating conspiracy theories about cold fusion and covid.
This is not cold fusion folks. They're bombarding with 2.5 MeV photons. If you had a material made up of particles with that average energy it'd be 29011312515 Kelvin.
- wilg 6y agoI'm just upset that they used the same name as the well-known software project GNU Fusion, which is liable to confuse most people.
- andrewflnr 6y agoYou almost got me.
- raverbashing 6y ago> the neutrons were created through photodissociation of deuterons via exposure to 2.9+MeV gamma (energetic X-ray) beam. Gamma rays, not neutrons
- jasonwatkinspdx 6y agoDoh, minor brainfart. Thanks, I corrected it.

- hliyan 6y agoI think they saw "deuterium atoms in a metal lattice" and associated that with one of the original hypotheses about cold fusion. But this fusion is anything but cold: A metal such as erbium is “deuterated” or loaded with deuterium atoms, “deuterons,” packing the fuel a billion times denser than in magnetic confinement (tokamak) fusion reactors. In the new method, a neutron source “heats” or accelerates deuterons sufficiently such that when colliding with a neighboring deuteron it causes D-D fusion reactions.
- mrhwick 6y agoHave you looked into chirped pulse amplification lasers?
- mikewarot 6y agoCosmic rays hit things at ground level at an average energy of 4 GeV, about 1/cm2/min according to this source: https://cosmic.lbl.gov/SKliewer/Cosmic_Rays/Muons.htm#:~:text=Muons%20arrive%20at%20sea%20level,of%20the%20primary%20particle's%20path https://cosmic.lbl.gov/SKliewer/Cosmic_Rays/Muons.htm#:~:tex.... This is also loading up deuterium in a metal lattice, getting fusion, and wondering how to commercialize it.
