New Aussie Fusion Technology February 25, 2020

The lateral-thinking Australian fusion start-up HB11 (from the University of New South Wales) patented a unique new fusion technology. Interestingly, this laser-driven technique uses no radioactive fuel(!), and much lower temperatures than “traditional” approaches employed by most fusion researchers involving heating deuterium and tritium fuel up to 15 million C.

I don’t need to tell you that method hasn’t worked yet, do I? Fifty-something years and no joy yet. I wonder why in an industry arguably filled with geniuses or at least Really Smart People that someone hasn’t said, “Hmmm…maybe we should try something new.”

UNSW Emeritus Professor of theoretical physics Heinrich Hora did. His research is being commercialized by HB11, which uses hydrogen-boron fusion wherein two lasers to push  atoms of hydrogen into boron. The lasers use “Chirped Pulse Amplification” technology, which won Gérard Mourou, Arthur Ashkin and Donna Strickland the 2018 Nobel Prize in Physics(!).

One laser creates the magnetic containment field for the plasma and the second laser triggers the ‘avalanche’ fusion chain reaction. The alpha particles produced by the reaction would create a positive electrical flow that can be channelled almost directly into the existing power grid with no need for a heat exchanger or steam turbine generator, and no chance of blowing the whole thing to atoms leaving a smoking crater.

The simplicity is pretty compelling…if it works. Time will tell.
