Polywell
Represents an alternative fusion pathway (IEC) funded by the Navy rather than DOE, targeting aneutronic p-B11 fusion for naval and space applications.
01 Definition
02 Detailed_Analysis
The Polywell is an Inertial Electrostatic Confinement (IEC) fusion reactor concept invented by Robert Bussard. The program was run through EMC2 Fusion Development Corporation with U.S. Navy funding. The key experiments were WB-6 (2005), WB-7 (2007-2008), and WB-8 (2011-2012). Navy funding ended in 2012.

Polywell / EMC2 — Navy-Funded IEC Fusion
Program Overview The Polywell is an Inertial Electrostatic Confinement (IEC) fusion reactor concept invented by Robert Bussard. The program was run through EMC2 Fusion Development Corporation with funding from the U.S. Navy. The key experiments were WB-6 (2005), WB-7 (2007-2008), and WB-8 (2011-2012). The Navy ended funding in 2012.
Strategic Relevance The Polywell is significant for the three-track architecture because it represents an alternative fusion pathway (IEC, not magnetic confinement) that was funded by the Navy rather than DOE. The use of p-B11 (proton-Boron) fuel would produce aneutronic fusion — no neutron radiation, meaning no need for heavy shielding. This is critical for naval and space applications where weight matters.
Key Details
- Founded by Robert Bussard (1928-2007), former Manhattan Project era physicist
- EMC2 Fusion Development Corporation
- Navy-funded via NAVAIR and ONR
- WB-6 demonstrated promising results in 2005 (Bussard's 'Wiffleball' effect)
- WB-7 and WB-8 were follow-on experiments
- Navy funding ended 2012; program status after that is unclear
- Bussard claimed p-B11 aneutronic fusion was achievable
- The program was relatively low-budget compared to tokamak programs
Connection to the Three-Track Architecture The Polywell represents the White Track's alternative fusion pathway. The Navy funding (rather than DOE) is significant — it suggests the Navy was interested in compact fusion for naval vessels, parallel to the Air Force's interest in compact fusion for directed energy (AFRL/MARAUDER/FRCHX). The end of Navy funding in 2012 coincides with the end of AAWSAP/AATIP funding, suggesting a broader pattern of program terminations in that period.
