Weren't the Iranians looking at a Polywell with multiple Magrids.

This bit of fluff is underwhelming. Another source

https://www.nasa.gov/directorates/space ... ent_Fusion

perhaps clarifies that this is merely an engineering study to determine that if an IEC device can magically achieve its fusion goals, how could it be engineered to meet NASA's dream of a reactor that produces about 2 KW/ Kg energy densities that would be beneficial for spacecraft weight considerations. Some very big assumptions must be applied as a starting point. It has almost nothing to do with the physics necessary/ achievable in such a machine to be a power producer.

A side note is that George Miley has proposed an IEC device as a high efficiency thruster (perhaps competing with more classical ion engines). Optimizing the engineering for best thrust to weight performance may be useful in this situation. But this has nothing to do with power generation. The power would have to come from solar panels or other source.

Looks more like a Farnsworth device.

Agreed, I just posted it because this is the first polywell related news I have seen in many weeks. Still waiting for the breakthrough funding announcement.
