Fusion Power By 2020? Researchers Say Yes and Turn To Crowdfunding.

Luminary Crush (109477) writes "To date, the bulk of fusion research has been channelled towards a plasma containment and stabilization method. This is the approach used by ITER's tokamak reactor, the cost of which could exceed US$13.7 billion before it's online in the year 2027 (barring further delays). Researchers at LPP Fusion, in a project partially financed by NASA-JPL, are working in a different direction: focus fusion, which focuses the plasma in a very small area to produce fusion and an ion beam which could then be harnessed to produce electricity. It is small enough to fit in a shipping container, can double as a rocket engine, and would cost US$50 million to produce the working 5 MW prototype. To reach the next hurdle and demonstrate feasibility, LPP Fusion has started an Indiegogo campaign to raise $200K."

  1. This was tried 35 years ago by InterGuru · · Score: 5, Informative

    This was tried as the Trisops Project 35 years ago but lost funding because all of the fusion energy project's focus was on the Tokamak.

    Trisops was an experimental machine for the study of magnetic confinement of plasmas with the ultimate goal of producing fusion power. The configuration was a variation of a compact toroid, a toroidal (doughnut-shaped) structure of plasma and magnetic fields with no coils penetrating the center. It lost funding in its original form in 1978.
    The configuration was produced by combining two individual toroids produced by two conical pinch guns, located at either end of a length of Pyrex pipe with a constant magnetic guide field. The toroidal currents in the toroids were in opposite directions, so that they repelled each other. After coming to an equilibrium, they were adiabatically compressed by increasing the external field.
