Post Summary:
This post explores a VC pitch. Demonstrating profitability after 7 years may be difficult. A case is made for urgency by the US military and government to build. If a machine was built, try running it with lots of low energy, tightly held electrons, few ions and ample space. The 2011 Iranian PIC simulation paper is explained, analyzed, and criticized. The work is poor. The design has too much metal. The paper does not address fusion, thermalization, the virtual anode or magnetic mirror theory. The Navy and Sydney groups are also briefly mentioned.

The 1989 patent expired and was re-filed in 2006. Since July 2011 this has been part of the prior art. Riders counter arguments are summarized. Next a six member team is suggested: a nuclear industry expert, a physicist, a marketer, a manager, a manufacturing specialist and a sales person. A prototype would need a vacuum chamber, vacuum pumps, puffer, fuel, electron guns, a neutron counter, a power supply, a coolant layer and the ring structure. Extras include: x-ray detector, a neutron recoil detector and a Thompson scattering laser detector. Device sizes are reviewed: Mark Suppes, (~6”) Joe Khachan, (~6”) WB-3, (~6”) WB-6 (~12”) and WB-7 (~12”). Planned devices: Joel Rogers, (~24”) AEO Iran, (~24”) and the Navy’s WB-8 are mentioned. An argument for a larger prototype is made. A design based on the six sigma practices of eliminating variation using interchangeable parts is sketched. Rings are designed so spacing can be adjusted on the fly (moot point – rings should be spaced so the axis and joint fields equal). Seven suggestions are made for operating success: finding a resonance condition, using head on collisions, x-ray reflection, running electron rich, exploiting the ion charge, exploiting ion injection, (now a moot point) and using direct conversion.

The advantages of grouping terms into dimensionless ratios for experimentation are discussed. Two groups: the ion-to-electron ratio and the beta ratio are mentioned. Rayleigh’s method and the Buckingham- Pi theorem are applied. Four ratios result and the Whiffleball number is considered as a possibility. A ratio of ion beam and electron cloud voltage is posited (now a moot point). A suggestion for mass and energy balances and the Lawson criteria is made. In Lawsons’ 1956 paper: the rate of energy loss is compared to the fusion rate and a critical temperature where they intersect is argued. The fusor (1964) breaks this convention by fusing at a low temperature and pressure. If the loss rate is reduced, it may cross the fusion rate at a lower temperature – lowering the critical temperature needed for net power. The practical advantages of this are discussed. Diagnostics and plasma instabilities are listed as yet-to-be examined topics. An appendix, examines the size of an electron.
