They're using a deuterium reaction? That's not bad (per se), but the neutron production can create difficulties: major regulatory hurdles (can be used for nuclear material refinement?), difficult to extract energy, and causes a lot of nearby material fatigue.

Another big contender (IMHO) is Tri Alpha's aneutronic approach: http://en.wikipedia.org/wiki/Tri_Alpha_Energy,_Inc.

Either way, cool stuff!

> Helion CEO David Kirtley says that his company can do it in three. Three... years? Decades? Days? Millennia?

We are hoping three years, three decades is just too late to matter. Part of what was not mentioned are the years that we have put into this already. Fusion is definitely a tough problem, but one that is worth it to solve.

Best of luck to you and your team, I really think that alternative paths to Fusion should have been explored since Farnsworth. Instead we have the crazy massive superconducting cathedral's that are literally trying to blow themselves apart when you turn them on. Your team and the teams investigating other approaches (General Fusion, Tri-alpha, the late Bussard's Polywell, Lerner's Focus Fusion) all should get several tens of millions to investigate and do hard science and try for the big payoff. Congrats on getting some more initial funding, I wish you the best of luck.

> Helion Energy [...] says it has a plan to build a fusion reactor [..], a challenge whose solution has been considered decades away for, well, decades. Helion CEO David Kirtley says that his company can do it in three. Three decades? Either this is a very long-term investment, or a very confusingly written article.

Yeah, that's a clumsy sentence. He means 3 years.

In this article, he estimates commercial viability by 2019:

Forgive me if this is forward, but are you guys hiring? I'm in no way a physicist, but I do know a few with strong experimental backgrounds (mostly in nuclear), and I try to keep my ear to the ground for intriguing job opportunities for my friends.

We are hiring for Redmond, WA, but only people that are excited and forward! Our Contact page http://www.helionenergy.com/ has the link.

What's the plasma configuration of the machine? I think there's a research group at U of Washington working on merging spheromaks which create a field reversed configuration. Is this a spinoff of that group?

edit: looks like it is - this is the group: https://www.aa.washington.edu/research/plasmaDynamics/phdx.h...

It's interesting that you can justify this investment in at least four separate ways, independently: 1) Even if there is a low chance of success, it would be wildly profitable if successful, and investing early gets you a good share if it's successful. 2) Fusion power would make the world a better place; investing in this way, when you already have huge returns and it's someone else's money, is actually rational even…

The risk of #3 is that they don't create fusion but they do develop a machine that can emit streams of hot plasma which is then turned into the Navy's weapon of choice for close weapons support on carrier battle groups. That said, I am looking forward to at least one of the fusion efforts bearing fruit. I'm something of an optimist here but I expect a durable solution to the 'energy problem' to emerge from our develo…

We've already weaponized nuclear fusion into the most destructive bomb ever created. It probably couldn't get a whole lot worse than that.

I think there are other paths to sustainable energy, but certainly viable fusion power is the holy grail.

Am I the only one who finds the names in this headline SO FRICKIN AMAZING?!

They are all so apt -- A steampunk-sounding mechanism for combining things[1], a mythical element/alloy of magical powers, and a naked Helium nucleus. It just tickles something very artistic for me.

Edit: [1] ok fine it's actually a math function, but I like my perception of the name better.
