However, harnessing commercially-viable fusion power involves serious technological challenges, including protecting the wall of the reactor vessel at extremely high temperatures and controlling the fusion reaction areas that the CRP helped to address.
Had this star formed with only a slightly lower mass, the fusion reaction of hydrogen in its core could not be sustained, and the star would instead have transformed into a brown dwarf.
The easiest fusion reaction to replicate in the lab is between two hydrogen isotopes, deuterium, extracted from water, and tritium, produced during the fusion reaction in contact with lithium.
Attempts to develop a controlled fusion reaction revolve around forcing two hydrogen isotopes (deuterium and tritium) to collide in a similar way.
Tri Alpha's setup borrows some of the principles of high-energy particle accelerators, such as the Large Hadron Collider, to fire beams of plasma into a central vessel where the fusion reaction takes place.
