General Fusion builds credibility on its ambitious path to demonstrate affordable fusion power for the masses

12-May-general-fusion-reactor-360Corporate website design on its own doesn’t reveal much about a company except how much it’s willing to spend on marketing. However, the timing of website designs and redesigns can tell you quite a bit. For example, if a new company goes live from Day 1 on the Internet with a flashy, slick, clearly expensive corporate site, it’s more than likely smoke and mirrors hiding a lot of nothing. However, when a company has been around for a few years and then suddenly decides to invest in a kick-ass website, it’s often — not always — a sign it has entered a new stage and finally has something concrete to brag about. Serious companies, in my experience, try to keep a low profile until they’ve got something real to say.

A superficial observation, yes, but I’m making this point to explain why I decided to contact nuclear fusion startup General Fusion of Vancouver for an update. As many of you will remember, I wrote a chapter about this Vancouver-based company in Mad Like Tesla — it’s one of my favourite chapters in the book. This week, the company, which counts Amazon.com founder Jeff Bezos as a financial backer, announced that two top-notch directors were joining its board: Jacques Besnainou and Frederick Buckman. Besnainou was former president and CEO of AREVA Group North America, while Buckman, who has a PhD in nuclear engineering from MIT, has pretty deep experience working as an executive with a number of electricity-sector companies, including Shaw Power Group, Brookfield Asset Management, and PowerLink Transmission Co., where he is currently CEO. After seeing this announcement, I decided to check out General Fusion’s website when I noticed the redesign, which is more professionally put together, visually attractive, and through excellent photos has a compelling narrative and offers a peak inside a company doing some very cool work. For this reason, and because it has been more than three years since I last spoke with the company, I decided to give CEO Doug Richardson a call for an update. Below is an edited excerpt of that conversation, though first you may want to read a couple of previous posts for a bit of background on General Fusion.

Clean Break: In Mad Like Tesla, I mentioned that General Fusion’s goal was to demonstrate net gain by 2014 with an eye to generating fusion power for the grid by 2020. When we last spoke, you said the trick relates to how you confine the plasma so you can achieve the right densities and temperature required to achieve net gain. I recall your comparison to a water balloon, and the difficulty of trying to compress it with your hands without letting the balloon squeeze through your fingers. How has your progress been on that front?

Richardson: We’ve struggled with getting the confinement and we’re probably at half of what we need. So we’re working on that…. The questions are, do we have the right water balloon, and can we improve our fingers so we don’t let any of the water balloon come through? On both those fronts we’ve made great improvements. Have we gotten to net-gain fusion conditions yet? No. Do I still believe we can get there? Yes. Has it taken longer than expected? Yes. Fusion is hard.
Clean Break: Over the past three years, do you feel you’ve gained acceptance in the broader scientific community, specifically in the area of nuclear physics?

Richardson: In the scientific community, we’re much more credible. People realize who we are. There was a guy recently doing an article on fusion in the United States. He phoned up a guy who runs a fusion conference for comment. The guy told him there are three areas he needs to look at : the laser guys, magnetic confinement fusion like ITER, and you have to talk to General Fusion. That’s an endorsement that the science we’re doing is getting noticed in the scientific community.

Clean Break: Have you been getting more attention and support from the Canadian government?

Richardson: I would say Canadian government at high levels, no. I would say associations within Canada, yes. For example, the Canadian Nuclear Society now has a fusion section in their annual meeting, and there have been a few other fusion meetings in Canada. The Canadian government really killed fusion dead. For that to change is a big challenge. It’s not happening.

Clean Break: While traditional nuclear fission approaches to power generation seem to be struggling, we are hearing quite a bit about the potential of fuel recycling, thorium reactors, small modular reactors, and other approaches. Do see yourself in a race against these alternative approaches to nuclear power generation?

Richardson: If we get it right, it completely blows everybody else out of the water. Some of those technologies may be better than heavy-water and light-water reactors, but they have a huge development path ahead. The thing that holds them back is the commercial viability. The real nuclear advances will come from Asia, even in fission. My understanding is that the Chinese have taken a CANDU reactor and loaded it up with thorium. Likewise, other types of fission like reburning spent fuel are being explored. This is going to sound a bit harsh, but it’s a bit like North America has decided to get out of nuclear. To be clear, the Tokamak (ITER) approach for fusion from a scientific point of view is further proven than the magnetized target fusion we’re doing. Tokamaks have gotten near net gain. We haven’t gotten anywhere near net gain. We can prove out the science on a way faster timescale than they did, and with a way smaller budget, but they are well ahead on the science. So until we demonstrate the science is valid, there’s is the way to go. If we demonstrate the science, Vancouver will be the global centre for fusion. If we prove out the science that fusion can work at inexpensive scale, it will enable fusion around the world and in all sorts of surprising ways that weren’t anticipated.

Clean Break: If you demonstrate the validity of the science behind General Fusion’s approach, do you really think a project like ITER will be discontinued with the billions of dollars already put into it?

Richardson: I actually believe that people are looking for a reason to scrap ITER, but they haven’t found a way to do so. I think the Chinese will have a version beyond ITER, perhaps built before ITER is built.

Clean Break: Jeff Bezos, through Bezos Expeditions, has put some money behind General Fusion. Has Bezos toured your facility?

Richardson: (pause)… I had a very fun lunch with Bezos.

Clean Break: And what was your impression?

Richardson: He’s an exceptionally smart, curious, practical, interesting guy with a zest for life.

Fusion power on the cheap? Not so outlandish…

My feature in the Toronto Star today is about General Fusion, a Vancouver-area startup that believes it can build a prototype of a nuclear fusion reactor for $50 million within four years. While the multibillion-dollar ITER and U.S. fusion programs are using costly lasers and electromagnets to achieve “net gain” — that is, creating a fusion reaction that releases more energy than put it — the folks at General Fusion are cleverly pursuing a mechanical approach that uses concentrated sound waves to compress a deuterium-tritium plasma and trigger a fusion reaction. The key, as you’ll see, is the use of precision digital controls that simply didn’t exist back in the 1970s when the idea of magnetized target fusion was first explored.

You can read the article for more details and a deeper explanation of how it works. General Fusion recently secured $13.9 million from Sustainable Development Technology Canada so it can pursue its prototype development, contingent on the company raising another $30 million or so from private investors. SDTC‘s average deal size is around $3 million so the fact it’s giving General Fusion nearly five times that amount speaks to the credibility of what it’s doing.
