From the NextBigFuture site: Jaeyoung Park confirms publication of patent filing for Polywell Fusion and promises more technical disclosure in interview with Nextbigfuture
Nextbigfuture interviewed Jaeyoung Park who leads the EMC2 commercial fusion effort. EMC2 is developing the work of late Dr. Robert Bussard for magneto-electrostatic fusion, also known as “Polywell fusion”. Dr. Park confirmed the recent publication of an EMC2 patent filing. Dr Park also discussed the reasons behind EMC2's silence, which had been driven by the Navy’s concern about technology disclosure of Polywell technology.
The patent filing (can be found here using the application number 14645306, http://portal.uspto.gov/pair/PublicPair) is based on a breakthrough of high-pressure plasma confinement that was described in a 2015 Physical Review X paper,
a leading physics journal. Park told Nextbigfuture that 14 versions of
the magnetically insulated grid device were made between 1994 and 2012.
The last one in the series, the WB-8, achieved ~30 times better
confinement than the previous one, WB-7. However, the neutron yields
were much less than WB-7, indicating necessary plasma heating was
missing in WB-8. This prompted re-examination of the magnetically
insulated grid approach.
