Here’s an overview of several fusion power projects: The Nuclear Fusion Arms Race Is Underway –  Motherboard.

And here is info on a couple of alternative fusion approaches.

General Fusion, a Canadian based company that has raised $33M so far from Jeff Bezos and other private sources, is aiming for a reactor by the end of this decade. They have recently revamped their website and offers more info:

• Burnaby’s General Fusion aims to tap clean fusion power: Fusion power at a fraction of the cost – Canadian Business
• General Fusion targeting commercializing nuclear fusion in about 2020 – nextbigfuture.com

Their innovative acoustic driven compression technique is illustrated in this animation:

Prof. John Slough of the Plasma Dynamics Lab at the University of Washington is involved with a couple of spinoff companies using tech derived from his group’s work on compression of  FRC (Field Reverse Configuration) bubbles of plasma.

The company Helion Energy aims to develop a fusion power system:

• The 4th in Helion’s series of groundbreaking prototypes is now operationa – HE – Oct.11.13“Previous prototypes demonstrated the breakthroughs that made possible a new path toward commercial fusion and yielded significant fusion yields with Helion’s design.  This prototype will take Helion one step closer to commercial scale fusion.”
• Helion Energy wins the PNW Cleantech Open  HE- Oct.18,13

The fusion propulsion project is based at the company MSNW LLC, which I recently posted about here: FISO: MSNW LLC and “the first realistic approach to fusion-based propulsion” – Space-for-All.

An updated overview was presented at the recent International Electric Propulsion Conference (IEPC2013) in Washington, D.C. : J. Slough, Electromagnetically Driven Fusion Propulsion, IEPC-2013-372
