Selling Fusion In Washington DC

This past weekend I traveled to Washington DC to talk with fusion folks. The place always feels like Vegas to me.  It seems like 98% of the jobs in Washington involve constantly speculating on what action our government will take next.  Predictions abound. To get something done, it takes alignment from a couple hundred decision-makers spread across the federal bureaucracy. Selling a fusion program into this hot mess has got to be challenging. Except for the few people involved; it is hard for most to appreciate. On that scale, supporters must have a simple message. A message, that answers something that policy-makers already want to hear. Sometimes, fusion is presented as the solution to climate change - and we just need to get ignition to make it work. Sometimes, fusion is sold as a path to energy independence; or military might. I heard a real example of a committee reversing direction, in the middle of a review. First, they were asked: what they could do with more - and then halfway through - were asked for what they could do with less. Broadly, it feels like our government is in a holding pattern. For about 25+ years, fusion has been viewed as a science project. But - there are signs that this might be changing.  

For years fusion has been stuck on the above treadmill in DC, now there are signs this might be changing.urcer

Science or Power?

Congress will support science projects. Sure, they funded an international space station. Yes, they funded a particle accelerator. They view fusion as the same kind of project. But if fusion stays as a science project - then it will always be tied down. This may not be obvious right away. But dig deeper and you realize something important. Science projects do not lead to commercial power plants. So, Congress will fund burning plasma research - but not work to lower the plants’ cost. DC will support a new plasma model – but not look at ways to make the machine more practical. This mentality has made lasting damage in the program; it has strangled off the engineering side of fusion. Sadly, it is not only politicians who take this view. Other bodies like the National Academy of Sciences and the Fusion Energy Science Committee repeat the same message.  They kind of have to. Any other message would be too difficult to sell. The Academy recently called for 200 million more to do a domestic tokamak program. Astoundingly, they might actually get their money. One policy person told me: "they have a lot of pull - members of Congress will sometimes just do with whatever the National Academy recommends."

The Dynomak, one promising fusion approach developed by start-up CT Fusion in Seattle. The company is a spin out from 30 years of work at the University of Washington and is having problems raising capital.

The Princeton Rotamak, has set a world-record for the longest stable FRC ever created. The project has had an annual budget of a few hundred thousand, and a small staff for 10+ years. In April 2018, the Chinese energy company ENN took an interest. They have since invested several millions and hired a staff of 15, in an effort to duplicate this work, in China. Meanwhile the US keeps ignoring innovations like this.


Today, there seems to be an undercurrent in Washington. Policy-makers are touring both ITER and TAE Technologies. They come back confused. There is a stark difference in the staffing, culture, time-lines and attitudes. ITER is not supposed to be turned on until 2025 - or later. The plan seems to be fund ITER and wait forever. Meanwhile, TAE already put fusion on the commercial marketplace two years ago. The company continues to set records in runtime and temperatures.  This is confusing for policy-makers. The wheels of government seem to be mulling this over.  It is slowly dawning on folks: fusion is not a science project but an energy project. If fusion becomes an energy project then the government must treat it radically different. So far, this is still an undercurrent - on the surface nothing has changed. In many ways, nothing will really change until the fusion community does something big (but please guys: no more hoaxes). 

One approach pushed by the startup Compact Fusion Systems in Santa Fe. This is a liquid metal crunching on a plasma structure; very similar to General Fusion's technology. CFS has a solid technical team of former researchers from Kirkland Air Force base, NRL and two private firms. They recently raised funding from Strong Atomics, a new venture capital firm, focused solely on fusion.

The Plasma Liner Experiment is a Los Alamos machine developed to test the idea of Plasma Jet Fusion.  The effort is being led HyperJet Fusion in Chantilly, Virginia. Hyperjet and Los Alamos recently raised ~$5.9M from ARPA-E, an outside investor and ~$2M from Strong Atomics, a new VC firm dedicated to fusion.

US is Already Behind:

If Congress suddenly woke up to fusion power – they might also realize that China is pulling ahead. The Chinese program has mushroomed recently. Developments started in 2011 during their last five year plan. This was the same time that Congress cut funding for last remaining tokamak at MIT. That same year, China started staffing up an INEST office outside Hefei. They now have 500 fresh PhD’s working on fusion and fission innovations. They recently tested the 3D printing of fusion components. Meanwhile, the US program is turning away young people because they do not have the support.  I personally have met many people over the years that could not find a position. Publicly, the INEST office is still supporting ITER – but privately they are very much eyeing the advances in mirrors and FRC. Meanwhile a billion dollar, Chinese energy company ENN has started a project to build a FRC based on the Princeton machine. The ground is fertile with ideas that have not been supported by the US government. Some are not American. For example, the gas dynamic trap in Russia recently broke through many of the problems that plagued mirror machines. Despite calls from US experts – the US has no mirror machine operating anywhere in the country. China has also moved into superconducting tokamaks. Today, Chinas' EAST is a top notch superconducting tokamak. The US has no such machine.  There is raw frustration over this in the fusion community. That anger cuts across all approaches. Everyone in this field agrees: policy-makers simple do not get how important this work is.

Lockheed-Martin Compact Fusion Reactor and the Polywell - two fusion approaches based on the concept that the plasma diamagnetism will reject the outside field. This could lead to an awesome plasma trap. EMC2 has struggled to raise funding in San Diego; while Lockheed has refused to publish results.

Over the summer of 2018, MIT announced that it had raised 50 million dollars in private investment. They formed a company, Commonwealth Fusion Systems. The group is going after a commercial, superconducting, tokamak.  This is in response to the frustration with fusion funding in the US. It also signaled something to DC. They have started to notice the fusion startups. Since then, Dennis Whyte, head of the plasma fusion science center, has been talking to anyone and everyone. Dr. Whyte is trying to seize the narrative, and he has a compelling pitch to make. The tokamak is the most well studied approach in all of fusion – and they want to combine it with the huge advancements made in superconductors. It is worth pointing out what superconductors mean for fusion. One startup in Colorado saw their performance increase by ~100 fold in field strength and a ~1,000,000 fold in run time due to BSCCO superconductors.  That is not even the best wire available. Moreover, the magnetic pressure should drive the fusion rates, exponentially. It is an holy #%$! improvement. Superconductors are so damn exciting; that almost everyone in fusion should be seriously looking at them.

The flowing z-pinch team at Uri Shumlaks' lab at the University of Washington. This effort was spun out into ZAP Energy Inc. In 2018, the company received a fresh $6.8 million in ARPA-E funding. By flowing the plasma through the Z-Pinch; the plasma can be made stable against magnetic-drive pressure instabilities.
A Fusion Ecosystem:
Tokamaks are far from the only approach in fusion; and CFS is far from being the only company. So far, they have been one of the few groups privileged enough to garner a 50 million dollar investment. But, if investors dig a little deeper they will find a wealth of good ideas. Good ideas that our government has utterly failed to support. Examples abound. These groups have a wide variety of technology - from established to crazy - so investor beware.  Some companies have found their new home in the Fusion Industry Association. This was started as an umbrella group for these little start-ups.

Washington State governor Jay Inslee touring the fusion startup Helion. This company has been in business since 2010 and has achieved a 100 Tesla compression of a merged Field Reversed Configuration. The company has raised over 10 million in private capital; notable from the accelerator Y-Combinator.

So what are we to make of fusion? Is it a science project or is power project?  Washington is certain still viewing it as a research program. Congress will probably continue to do so until the fusion community has some breakthrough; a tipping point. The danger is that the administration will react badly to these changes.  If Congress cuts funding for fusion as a science project - there is no guarantee that money will then go to fusion as a power project.Really, fusion funding does not need to be so complicated. What we need is very simple. We need an idea pipeline. We need something similar to what is used in biotech. Fund 20 ideas at 5 million a year, 10 ideas at 10 million and small handful (aka ITER) with the big budgets. Force groups to move up or down the ladder as they move closer to the power plant. That means using cost, runtime and Q as meter sticks to measure everyone by. This is not complicated, folks.

  2. Wash your hair every day at least three to ten days in advance with the Aloe Toxin Rid, and use the Ultra Clean shampoo only on the day of your drug test since the effects last for 24 hours. You can also take multiple showers a day for better results. Remember to wash your hair thoroughly and lather it for at least 10 to 15 minutes. While showering specifically, focus on the scalp because the hair sample will be taken directly from there for the drug test. Are you curious why? This is because the scalp hoards all of the toxins and is full of oil layers. So, make sure you thoroughly rinse and wash your scalp. So, from now on, utilize your shower sessions to prepare yourself for your upcoming hair drug test with this hair follicle shampoo, which is one of the best THC detox methods. Remember to wash off any items you used before that came in contact with your hair, as they can reintroduce or increase toxins in your hair. So, avoid any kind of things like pillowcases, beanies, hats, headbands, and bandanas, etc. And, if you do come in contact with these, make sure you wash your hair before your test. An oral drug test produces really fast results, and it is frequently used for on-the-spot mouth swab drug tests. Now, there is no need to fear any mouth swab tests, because we have a remedy that will help you pass your drug test. A hair follicle is in constant contact with the bloodstream. Over time, toxins and impurities in the blood build up in the hair follicles they’re connected to. That’s why a hair follicle test can find drug residue as far back as three months. These replicas come in a variety of skin tones to help fool even the most diligent observers

  3. I came here looking for info on Bussard's EMCC and polywell, vs Microsoft's news with Helion ... I'm sorry to not see recent news about EMCC and that your publishing of new info has gone quiet ...

    I suspect part of this is the time margins in congress and the usual infighting, part is the lack of strong need expressed by the Navy, especially since Russia has demonstrated their [ lack of ] threat level in Ukraine and China has a show-off (too-low-headcount) military and PLANavy rather than a valid expeditionary invasion force or true naval power.

    But my interest is in fusion for spaceflight and for grid-power.
