Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain nuclear fusion in stars and in energy research accurately, distinguishing experimental milestones from commercial reality and flagging unconfirmed claims.

A nuclear reaction in which light atomic nuclei combine to form a heavier nucleus, releasing energy; it powers the Sun and stars and is pursued for electricity through magnetic and inertial confinement research, while claims of cold fusion remain unconfirmed.

What it is for: Understanding stars and a potential future energy source.

It can be explain fusion reactions and conditions; describe research approaches; assess claims of breakthroughs against sources; compare with fission.

Distinguishing features

Light nuclei combine

Requires extreme temperature and pressure

Powers stars

Not yet commercial on Earth

What it looks like

Not visible directly; seen as starlight, plasma glow in devices and research facilities.

How it is recognised

Tokamaks, stellarators and laser facilities

Deuterium-tritium reactions

Fission splits heavy nuclei instead
