KSTAR is one of the most advanced Tokamak-style reactors in the world. These devices use powerful magnetic fields to shape super-heated plasma into a torus (ring) shape. The longer plasma remains active in the reactor the more likely the atoms will undergo fusion and produce usable amounts of energy.
Is there a functioning fusion reactor?
The Wendelstein 7-X reactor, which uses a complex design called a stellerator, is performing just like it was predicted to. Last year, Germany completed and turned on the Wendelstein 7-X nuclear fusion reactor.
Where is ITER fusion reactor?

Does the US have a fusion reactor?
If the blanket contains lithium, the neutrons will split some of those nuclei to form more tritium. But tritium is a highly regulated radioactive substance that’s difficult to handle, and Lyman questions whether such a closed system can be developed by 2035.
Who is investing in fusion energy?
The fusion start-up Helion Energy announced a $500 million funding round on Friday. The round was lead by Silicon Valley investor Sam Altman, who put $375 million into Helion, his largest investment in a start-up ever.
What is zap energy?
Zap Energy’s technology stabilizes plasma using sheared flows rather than magnetic fields. Driving electric current through the flow creates the magnetic field, which confines and compresses the plasma. The higher the current, the greater the pressure and density in the plasma.
Is cold fusion theoretically possible?
There is currently no accepted theoretical model that would allow cold fusion to occur. By late 1989, most scientists considered cold fusion claims dead, and cold fusion subsequently gained a reputation as pathological science.
What is a Polywell fusion reactor?
The polywell is a proposed design for a fusion reactor using an electric field to heat ions to fusion conditions. The design is related to the fusor, the high beta fusion reactor, the magnetic mirror, and the biconic cusp. A set of electromagnets generates a magnetic field that traps electrons.
How does a high beta fusion reactor work?
The design is related to the fusor, the high beta fusion reactor, the magnetic mirror, and the biconic cusp. A set of electromagnets generates a magnetic field that traps electrons. This creates a negative voltage, which attracts positive ions.
What is the plasma regime of a polywell?
Most experiments on polywells involve low-beta plasma regimes (where β < 1), where the plasma pressure is weak compared to the magnetic pressure. Several models describe magnetic trapping in polywells.
What is the difference between a polywell and an ion beta?
The polywell concerns itself only for the electron beta, whereas the ion beta is of greater interest within Tokamak and other neutral-plasma machines. The two vary by a very large ratio, because of the enormous difference in mass between an electron and any ion.
