Focus fusion (or Plasma Focus Fusion) is an electricity generation approach with a device known as a dense plasma focus (DPF), used as a nuclear fusion generator with hydrogen-boron fuel (pB11).

The single biggest difference between a generic Mather style DPF and the Focus fusion approach is the patented theory of operation (US Patent #7,482,607) which predicted, and which preliminary experiments seem to confirm, that adding an Angular Momentum Coil increases performance (neutron yield when operated in Deuterium) by controlling the plasma’s spin during the axial phase and well into the radial phases, including magnetic compression.

The Focus fusion test program is scheduled to achieve its goals in calendar 2010.

The pB11 fusion reaction is:

p + B11 -> 3 He4 + 8.7 MeV

The Focus Fusion approach utilizes an aneutronic fusion reaction.

Proposed economic benefits

The potential of this approach towards achieving net gain of fusion energy in an economical way consists of the following :

  • the energy from fusion reactions is released mainly in the form of a high energy pulsed beam of helium nuclei, being already electric current
  • no expensive thermal conversion is needed , no expensive turbine , pressurized equipment
  • the reactor utilized is small and cheap in comparison to ( nuclear reactors , coal power stations , fusion tokamak reactors) "Conventional Fusion vs. Focus Fusion". Focus Fusion Society Site. 2010-04-23. Retrieved 2010-04-23. {{cite web}}: Check date values in: |date= (help)</ref>
  • cheap , extremely condensed and abundant fuel is used
  • no radioactive waste issues, since no neutrons are produced as by-product [1]
  • no fossil fuel related issues and hidden society costs
