NearStar Fusion is a company in Chantilly, Virginia, developing a pulsed approach it calls Magnetized Target Impact Fusion. Its central component is a plasma-armature railgun that the company says will launch 50-gram fuel capsules at 10 km/s once per second; it describes its approach as building on the method of imploding metal fuel liners used on Sandia's Z machine. It plans to use deuterium-deuterium fuel, avoiding tritium, and says pulsed operation avoids the difficulty of holding a plasma steady and that its modular plant could replace the heat source in existing coal plants. It also proposes the railgun technology for space propulsion. The company says its team's past fusion work was funded by the Department of Energy, ARPA-E, NASA and the National Science Foundation, and it raises money from the public through equity crowdfunding on StartEngine.

Terms
- Magnetized target
- A magnetised plasma target compressed mechanically or by an imploding liner. Sits between magnetic and inertial confinement in density and timescale. The main open problem is compressing the liner onto the plasma symmetrically and fast enough to reach fusion conditions before the plasma cools or the liner breaks up.
- Deuterium–tritium
- Lowest ignition threshold; 80% of energy in 14.1 MeV neutrons. The reference fuel for every near-term net-gain claim.
