Study Claims Quark Fusion May Be the Energy Source of the Future
In a new paper, scientists have envisioned a new power source straight out of Star Trek. While nuclear fusion reactors, which produce energy in the same way as the sun, are still not a viable reality, researchers from Tel Aviv University and the University of Chicago are proposing quark fusion.
Quarks are super-tiny elementary particles that combine to form protons and neutrons. There are six kinds of quarks,including up and down quarks, which are found in protons and neutrons, and heavier charm quarks.
The way we can produce quarks is through particle accelerators like the Large Hadron Collider in Switzerland, which can smash protons and neutrons to break them up into quarks.
What the researchers Marek Karliner and Jonathan Rosner, who wrote the paper,are saying in their analysis is that if these quarks were then recombined, they would release large amounts of energy. Specifically, the researchers calculate that quark fusion could produce as much as eight times the energy of nuclear fusion (which uses hydrogen atoms).

The only challenge to this amazing source of cheap energy – figuring out how to do it. Among the challenges is understanding how to produce the heavier quarks which are to be combined with lighter quarks from the proton and neutron collisions. The researchers are planning to test the theory first using the Large Hadron Collider.
Of note is that the researchers didn’t initially want to publish their theoretical findings, afraid of proposing this kind of massive energy release especially since hydrogen fusion is central to hydrogen bombs. They have subsequently calculated that a chain reaction necessary for such an explosion would be impossible using quarks as they exist for too short an amount of time.
