A Gallery of Small Fusion Startups

General Fusion
General Fusion is a small startup headquartered near Vancouver, BC. The compression of plasma to achieve fusion is accomplished by a coordinated spherical plasma compression, using pneumatics and advanced switching.

Helion
Helion Energy is located in Redmond, Washington. It is based on a principle of "colliding plasmas," and like all the rest of the small fusion approaches, it is a long shot.

Bussard IEC Fusion
Bussard inertial electrostatic confinement fusion (EMC2 Fusion) involves an electrostatic plasma confinement to achieve fusion. The history and development of the concept is explained in a video reached via the link above. The Bussard IEC (Polywell) has been financed almost entirely by the US Navy. EMC2 is based near Santa Fe, New Mexico.

Dense Plasma Focus Fusion
Lawrenceville Plasma Physics is based in New Jersey. The dense plasma focus approach uses a special pulsing "spark plug" to ionise a gas, and to form a plasmoid "pinch," with the emission of high energy photons, ions, and fusion neutrons.

HyperV
Hyper V Technologies utilises a spherical array of mini railguns to accelerate plasma beams into a central target of deuterium or deuterium-tritium, to achieve fusion (hopefully).

TriAlpha
TriAlpha is an Irvine, California venture, which has been fairly successful in the venture capital game. TriAlpha is a bit secretive with non-investors, but you can read their patent for yourselves. The concept seems to involve the highly sophisticated evolution of an earlier colliding beam fusion approach.

Fusion reactors can be prolific neutron generators, and could be utilised for the transmutation of nuclear wastes into harmless compounds. They could also generate a number of different highly energetic particles and high energy photons, and used for a number of purposes -- including as space propulsion. Another potential product of fusion reactions is valuable high temperatur process heat. But what is most desired from fusion reactors at this time is abundant, cheap, clean electrical power.

The energy yield from fusion is higher per unit fuel mass than the energy from fission, so that less fuel mass is required to generate equivalent energies. Fusion is generally safer, with less radioactive waste remaining to be disposed of.

Many billions of dollars have been spent by governments in a vain attempt to master the power of the stars on a more human scale. If one of the small startups manages to achieve with $millions what huge government budgets of $billions could not achieve, a revolution would have been ignited which would likely not stop with just cheap, clean, abundant energy.
