Notes From Why STELLARATORS are the future of Fusion Energy
A Stellarator is a different design for a fusion reactor than the Tokamak.
Fusion is a different kind of nuclear power that produces no waste and does not cause nuclear explosions, but the machine can still explode in the conventional sense, if superconductivity in the magnets is lost.
In both charged particles spin in a roughly toroidal shape (donut shaped or torus shaped).
To help with confinement, the Stellarator twists the stream of particles as it spins it. It uses two helical magnetic field coils around the torus. (DNA is also shaped like a double helix)
Stellarator can be built for a billion dollars versus 63 billion dollars for the ITER — the most advanced fusion reactor under construction.
Like Tokomak’s, there are Stellarators in labs in the real world.
