The Spheromak 

MAGNETIC TOPOLOGY
The spheromak has either httle or no "hole" through it, but the dynamo drives the fields -and currents to a topology similar to the tokamak. Even with a hole, there is no material (magnets or conductors) through it. As with the RFP, the dynamo drives the configuration towards a stable, minimum-energy state.

ADVANTAGES

• Simple magnet set (circular coils).
• Internal magnetic fields and plasma current
  generated primarily by the dynamo.
• A compact, less expensive power plant.

An advanced spheromak will address reactor- relevant physics and technology. (Conceptual design from Lawrence Livermore National Laboratory).

A spheromak power plant- the simple geometry offers opportunities for innovative power production, such as a flowing liquid metal "blanket" for heat removal.
