We’ve been sent this press release claiming a new kind of fusion reaction that works at small scales using an incredibly exotic fuel material: ultra-dense deuterium. We looked into it with an open mind, and if we’re being kind we’ll conclude that there’s a ten-year long research project being undertaken by [Leif Holmlid], a single scientist whose claims would win him one or two Nobel prizes if any of it were true.
If we drop the kindness and approach it rationally, this doesn’t smell right and can’t be believed until it has been reliably reproduced by someone not associated with the original research. Let’s delve into the claim of Deuterium powered reactions, and circle around on the cold-fusion hype we found so sadly entertaining back in the ’90s.

[Will Jack] built a heavy water fusion reactor and then won district and regional science fair projects with it. Someone give this man a job!
We looked in on his fusion reactor about a year ago. At the time he had managed to build a magnetic containment field but didn’t have the voltages or the deuterium necessary to achieve fusion. We’ll that’s all changed. Using a boron-10 lined sensor tube he’s managed to detect the rise in neutron counts that would indicate fusion. Remarkable. He’s now working on a refined gas system that will allow him to increase the deuterium purity by cutting down on the leak rate. He mentions a few other hardware improvements such as a new containment unit and an ion source upgrade. Both of these concepts go beyond our knowledge so do make sure to put on your Nuclear Engineering hat while reading through his project update.
Do you ever wonder what projects your neighbors have going on in their basements? [Will Jack’s] neighbors might be surprised to find he’s building a fusion reactor. The first step toward completing a Farsworth-Hirsch Fusor is up and running. The picture above shows heated plasma contained in a magnetic field. Next he just needs to up the voltage and inject some deuterium.
Yeah right! Deuterium, aka heavy water, is extremely rare and very difficult to refine. If you’re not familiar with the substance, you should get your hands on the NOVA episode: Hitler’s Sunken Secrets.
We’re glad to see that [Will Jack] is donning a lead vest for protections. [Will O’Brien] cautioned us about the stray X-rays these things produce when he covered fusors back in 2007.
