NASA Detects Lattice Confinement Fusion

Compact fusion reactors will probably be the most exacting and powerful durable devices, pound for pound, that mankind has ever created.

Erbium instead of Palladium. Takes me back...

The only other use for Erbium I know of is to dope optical fibers to make in-line amplifiers powered by light.

Cold fusion lives on it seems.

Though 2.9MeV isn't "cold"; it's around ~3e10 Kelvin.

You can't really compare the energy of a particle beam to temperature - temperature is only really defined in equilibrium and macroscopically.

Also, from the article,

> "In the new method, conditions sufficient for fusion are created in the confines of the metal lattice that is held at ambient temperature."
