With fusion devices having trouble to confine the plasma for long times, I wonder if a massively-parallel fusion plant woud be feasible. Let's assume that plasma destabilisation does not damage the device, and is a mundane event. Build 10 or even 20 fusion devices (economy of scale!) feeding the common heat buffer, e.g. a large reservoir of a molten salt or metal. Feed conventional turbines off the heat of the heat t…
The whole goal of fusion is to get the energy amplification, Q, to be > 1, which requires the triple product n T t to be above some threshold. n is density, T is temperature, t is confinement duration. This is Lawson's criteria, you should look it up to educate yourself.
Your proposal doesn't help n, T, or t, hence doesn't help Q.
Also, there are economic and physical gains from concentrating your efforts into making your fusion reactor larger, rather than trying to make it 1/10 the size and have 10x of them.
The economies of scale will happen once fusion ignition (Q>1) is achieved and we start mass producing dozens of fusion plants around the world. But at this point we're likely 10+ years away from achieving ignition.
