How Nuclear Fusion Can Benefit Us … TODAY! Check out the RoyPow Sun Series batteries here: https://www.roypowtech.com/ress/ or email [email protected]. I had a chance to visit a new startup that’s made an exciting nuclear fusion discovery that could have a major impact on our lives, like in nuclear medicine, today. It’s an interesting combination of inertial confinement fusion (IEC) and lattice confinement fusion (LCF). So put the jokes of fusion power always being 30 years away to the side. This is really cool … or should I say hot.

Content

0.229 -> This video is brought to you by RoyPow.
2.79 -> What if I told you that I got to see first hand a really interesting nuclear fusion discovery
6.589 -> that could impact our lives … today?
8.5 -> Before you start dropping frantic comments, just hear me out.
12.24 -> If you’re like me, the word “fusion” makes your mind go straight towards the long
15.12 -> quest for net positive electricity production.
17.8 -> Just look at the news about nuclear fusion just from the past few years and there’s
20.62 -> a huge amount of advances that have happened … but fusion power is still a long way off.
25.44 -> But that’s not the only thing fusion is good for.
28.13 -> In fact, fusion has the potential to improve lives today.
30.77 -> I “know” (just like I’m sure all of you do) that radiation plays an important
34.719 -> role in medicine, like medical isotopes that are used for detecting and treating cancer,
38.79 -> but I never knew how they were made.
40.85 -> Then there’s the story of the complexities and challenges of producing them and getting
44.38 -> them to the patient before their very short half-lives expire.
47.23 -> I had a chance to visit a new fusion startup that’s made a really interesting discovery
51.039 -> in the world of fusion that could have a major impact on our lives, like in medicine, today.
55.82 -> So put the jokes of fusion power always being 30 years away to the side.
59.82 -> This is really cool … or should I say hot.
62.76 -> I’m Matt Ferrell … welcome to Undecided.
72.02 -> The whole reason I make these videos is to share my excitement and interest in technology
75.84 -> and in what humanity is capable of when we put our collective minds to a very difficult
80.17 -> problem.
81.17 -> I’m not a scientist, so these videos are also me sharing my learning journey.
83.71 -> I’ve had an opportunity to meet and learn from some incredible people trying to leave
87.659 -> a dent in the universe.
88.659 -> And my journey over to the UK to meet with the team from Astral Systems is a prime example
93.009 -> of that.
94.009 -> In fact, I’ve kind of dubbed my UK trip as my “UK nuclear tour.”
97.43 -> This is the final video in the series, so be sure to check out my visits to the UK Atomic
101.57 -> Energy Authority and First Light Fusion.
103.939 -> Astral Systems is doing something different from what you might expect.
106.649 -> This isn’t about creating net positive electricity production.
109.26 -> They’ve discovered what they’ve dubbed Multi-State fusion.
111.57 -> In essence, it’s a combination of Inertial Electrostatic Confinement fusion and Lattice
116.329 -> Confinement Fusion.
117.42 -> And if you have no idea what any of that means, neither did I, so let’s get into it.
122.38 -> Just for some quick context, which is important for understanding what they’re doing, fusion
126.299 -> is all about slamming two positively charged things together, like nuclei or protons, which
130.989 -> reconfigures them into different nuclei and releases energy.
135.03 -> The important thing to keep in mind is that two positively charged things don’t want
138.62 -> to combine together.
139.84 -> They actually repel each other.
141.06 -> Think about taking two magnets and trying to push the matching north ends together.
145.59 -> This is the Coulomb force, or electric force, that makes fusion a challenge, because we
150.01 -> have to expend a lot of energy to push those nuclei fast enough to overcome that repulsive
154.48 -> force.
155.48 -> And on the other side, we have the incredibly strong nuclear force that’s holding the
158.16 -> nucleus together.
159.16 -> It’s kind of like trying to roll a boulder up and over a hill.
162.51 -> The hill is the Coulomb repulsion.
164.069 -> Everyone is trying to find the most energy efficient way to roll the boulder up the front
168.18 -> side of the hill to take advantage of the steep downhill on the other side.
172.34 -> That’s when the boulder starts rolling down the other side as fast as it can.
176.01 -> It’s all about finding the best way to reduce the amount of energy needed to roll that boulder,
179.72 -> so we don’t have to climb as high or we can get a bigger running start.
183.409 -> That’s really straining that analogy … a better one might be a roller coaster.
187.41 -> The downhill side is the same as releasing the energy for fusion.
190.2 -> That’s where Astral is doing something interesting by combining two techniques together.
193.66 -> But before we get to that, there’s another interesting technology that you can actually
197.29 -> get for your home today, and that’s from today’s sponsor, RowPow.
200.54 -> Their Sun Series line of batteries is perfect for combining with home solar to achieve energy
204.64 -> independence and whole-home backup power.
207.01 -> I’ve talked about this before, but the perfect battery technology for home use is Lihtium
210.97 -> Iron Phosphate (LFP) because it’s incredibly safe, reliable, and has a long lifespan.
216.71 -> The Sun Series is taking advantage of that, plus it has additional safety features and
220.48 -> a smart battery management system.
222.28 -> I love how RoyPow has made this a truly modular system, so you can easily size it to your
226.97 -> needs.
227.97 -> The US model starts at 3.6 kW output and 5.1 kWh storage, but can scale all the way up
233.63 -> to 15 kW output at 40 kWh of storage.
237.78 -> Just add on module by module.
239.36 -> All in a sleek, modern design.
241.489 -> There’s a web and mobile app available to monitor your system and change any settings.
246.04 -> If you’re interested in energy backup or building out a more self sufficient solar
249.17 -> powered setup for your home, you really should give RoyPow’s Sun Series a look.
253.11 -> It’s backed up with a 10 year warranty, and like I mentioned before, LFP batteries
256.479 -> are extremely safe and are absolute workhorses.
259.609 -> Check out the Sun Series batteries at link in the description below.
262.47 -> Thanks to RoyPow and to all of you for supporting the channel.
265.82 -> In a nutshell, Inertial Electrostatic Confinement Fusion, or IEC, is using electric fields to
271.75 -> confine and heat a plasma of hydrogen isotopes to the point where they fuse together, releasing
276.919 -> energy.
277.919 -> The entire system is taking advantage of the Coulomb force by jolting the entire system
281.58 -> with a massive negative charge, so that positively charged ions, protons, and nuclei are forced
287.18 -> towards each other by the same Coulomb force.
289.31 -> Essentially, it’s using the “opposites” attract of the negative charge and those positively
293.35 -> charged ions to get things moving, and “likes” repel logic, of those positively charged ions,
299.02 -> against itself to get the particles moving very fast.
301.97 -> It’s using speed to get the boulder up and over the hill.
305.88 -> This is where Lattice Confinement Fusion (LCF) comes into the picture.
309.8 -> In most reactor plans, researchers are only using one method, like the bigger running
313.56 -> start to get up over the hill.
315.169 -> If IEC is getting the boulder going fast, then LCF is all about smoothing the path … or
320.33 -> lowering the height of the hill.
321.33 -> LCF is a method of achieving nuclear fusion reactions by using a lattice of special, electron-dense
322.33 -> metals to confine the fuel.
323.33 -> LCF combines the principles of fission and magnetic confinement to achieve fusion reactions
324.33 -> at low temperatures.
325.33 -> Even though the Coulomb repulsion of the nucleus is still strong, by putting the fusion material
326.33 -> in the heavy metal lattice it’s fighting against a sea of negative charges making it
327.33 -> slightly less effective.
328.33 -> This lowers the hill, which makes it less difficult to get positively charged materials
329.33 -> to the top of the hill.
330.33 -> That’s a lot to take in, but in short … Astral is combining two relatively successful but
331.33 -> independent methodologies into one and seeing incredible synergies.
332.33 -> Here’s how Talmon Firestone, the CEO and co-founder of Astral Systems, broke it down
335.05 -> for me.
336.05 -> We're using a traditional plasma as almost like a spark plug that initiates fusion in
341.51 -> solid materials as validated by NASA.
344.819 -> So NASA calls this phenomenon lattice confinement fusion right?
348.84 -> But we don't use … we're not building a lattice confinement fusion reactor because
352.55 -> it's not just one, it's two states.
355.1 -> It's a mixture of IEC and a mixture of Lattice Confinement.
358.259 -> We call it Multi-State fusion because we're producing fusion in a plasma … and in a
362.819 -> solid material at the same time.
364.93 -> And that's what really drives the fusion performance up because we're not increasing power input.
369.86 -> There's no magnetic field entrapment that's doing anything.
374.54 -> It is simply doing a second layer of fusion simultaneously using the same power input,
381.75 -> and that's driving performance by orders of magnitude improvement.
384.68 -> You're getting more bang for your buck out of it.
388.13 -> Absolutely.
389.13 -> This is where my brain was breaking a bit, because Astral is building off of previous
392.51 -> discoveries in a very clever way … and my brain isn’t very clever.
396.25 -> In Lattice Confinement, there’s a reaction happening in the metal.
399.87 -> Basically, the crystalline layer of metal atoms in the surface of the chamber are being
403.31 -> used to hold the smaller atoms of a fuel like deuterium.
407.229 -> Doing this allows you to pack way more atoms of a given fuel into a tighter space than
410.87 -> you’d get in a typical tokamak reactor.
412.99 -> That higher concentration increases the odds of the deuterons hitting each other.
416.599 -> Tom Wallace-Smith, the co-founder of Astral Systems, is the person behind the discovery
420.4 -> of Astral’s Multi-State fusion approach.
422.669 -> He walked me through their test device.
424.87 -> So this is a research reactor that we have.
428.27 -> You see these numbers on the top is because something that I didn't expect going into
432.58 -> nuclear physics is how many times it'll be undoing and redoing nuts and bolts.
437.16 -> You have a different sequence, so you can maintain the proper gasket seal.
440.479 -> So you could open and close the chamber and you can replace components quite rapidly.
444.49 -> Different cathodes, different added materials, different probes, different samples.
449.56 -> We have a window down here so you can view the plasma.
451.669 -> You can do spectroscopic measurements as well.
454.31 -> We have two pressure gauges … valves.
457.729 -> These are the pumps to get down to low vacuum.
460.24 -> You can get down to as low as 10 times minus six Pascals and about 10,000 pascals atmospheric
466.889 -> pressure.
468.18 -> Just here, just so you can see as a demonstrator, we have deuterium getter bed, which is essentially
474.49 -> used for hydrogen storage.
475.75 -> You have a metal, which can sort of soak up hydrogen and store it in a hydro form at lower
481.97 -> temperatures.
482.97 -> And then if you heat it up, then you get a pressure of gas coming off that you can introduce
486.31 -> to the chamber.
489.05 -> This is needed so you don't get lightning bolts.
491.139 -> It's called a ceramic feed through.
493.13 -> So it stops short circuiting between the very high voltage so, at the moment we've got about
498.699 -> 50 kilovolt power supply plugged in, which is used for this system which can go up to
502.12 -> a hundred.
503.55 -> These two are much larger for, as you can probably tell, and they go up to about 200
508.18 -> kilovolts and 7.2 kilowatts.
511.5 -> And this system essentially was made in 2021.
515.26 -> And it's kind of like the workhorse.
516.4 -> I dunno if you can see the small blemish on the front that's from arcing events.
521.779 -> That's what happens when you put a large amount of power into these systems when you start
524.87 -> to try and produce meaningful amounts of neutrons.
527.18 -> Before I had that conversation with Tom and Talmon, they started up the machine to fire
530.18 -> up the plasma using a very low power level.
536.258 -> And we have plasma.
540.761 -> As you see, as you increase the current...
544.519 -> ... the brightness increases.
547.587 -> And we have different colors.
550.836 -> And this is a brand new cathode that has never been tested before.
555.331 -> With this geometry. It's been 3D printed.
559.493 -> If you look closely you'll see small sparking events.
564.292 -> And that correlates to the fact this is new and still conditioning.
568.76 -> So you having tiny dust particles getting burned off by the plasma.
572.671 -> And a little later in the afternoon, Dr. Mahmoud Bakr Arby from the University of Bristol stopped
576.94 -> by to fire up the system at a higher power level.
579.5 -> He was formerly the Chief Fusion Physicist at Kyoto University in Japan and an academic
583.88 -> collaborator at Astral, and is a senior research fellow at the University of Bristol.
585.82 -> Before we get into that though, I want to hit on why their discovery and machines are
589.8 -> a potentially big deal for the medical community.
591.49 -> It has more uses than just medicine (I’ll touch on that later), but that’s their initial
596.08 -> focus.
597.08 -> Tom Scott has a fantastic video on his YouTube channel about the manufacturing of radioactive
600.57 -> medical isotopes and how one location shoots them underground to the hospital at high speed.
605.76 -> It’s necessary because the isotopes they’re using have a half-life of minutes, not hours.
610.98 -> If you haven’t seen it, definitely check it out.
613.13 -> One thing you’ll notice immediately when they show the facility and particle accelerators
616.65 -> that are used is that they are massive.
619.86 -> Radioactive medical isotopes are typically made using particle accelerators, such as
622.95 -> high-energy and high-power electron linear accelerators.
626.52 -> These accelerators produce the isotopes by bombarding stable materials with high-energy
631.36 -> particles, such as protons or neutrons.
633.959 -> The isotopes are then separated from the target material and purified for use in medical applications.
639.12 -> This process is important for producing isotopes used in medical imaging and cancer treatment,
643.97 -> such as technetium-99m, which is used in over 80% of all nuclear medicine procedures.
648.279 -> In that case, you’re looking at a half life of six hours.
650.98 -> That’s not much time to get the treatment to the patient, which means these facilities
654.88 -> need to be built close to hospitals.
656.66 -> However, they’re so large and require such massive amounts of power that it’s not economical
660.72 -> or practical to build them everywhere.
663.02 -> Only key hospitals have access to these treatments, which limits the number of people that have
666.82 -> easy access to it.
667.97 -> As you probably noticed with Astral’s test device, it’s tiny … like really tiny.
672.829 -> They actually have an older model of an IEC device that Talmon's previous company used
676.87 -> to sell for industrial and research applications.
678.73 -> In fact, a lot of the parts they’re using are from already existing devices that have
683.13 -> a long track record.
684.649 -> Their device is going to be capable of producing medical isotopes in a very, very small size
689.18 -> and lower cost.
690.66 -> This will bring isotope production to far more hospitals and locations around the world.
694.98 -> Most of those are being produced at linear accelerators, but still with a two-hour or
698.45 -> six-hour half life patients can only receive those diagnostic procedures of PET scans close
705.2 -> to an accelerator.
706.2 -> And accelerators are $10 - $100 million.
709.83 -> To buy and run and they're finicky.
711.85 -> They gotta spin them up by hours, spin them down by hours.
715 -> But our systems are on/off anytime you want.
717.12 -> Earlier you saw it on, and we'll have it on a video you see around, it's just a few minutes
721.62 -> of waiting for a warmup and go, and it goes off.
724.83 -> And these are industrially designed.
725.83 -> And they’re moving fast to demonstrate what they’re capable of producing.
727.97 -> We are looking to demonstrate small batch isotope production.
732.779 -> You asked the question about which type.
734.529 -> Lutetium 177 we want to go for, which is a really, really hot isotope for use.
739.04 -> It was for … until now ... it was only used for prostate cancer.
742.12 -> But like within the last, or like recent, I don't know exactly, but within, let's say
743.829 -> the last few months, it's been approved for 23 different cancers.
748.019 -> So the demand for Lutetium 177 is supposed to 10x or a 100x in the next decade.
753.8 -> And we can demonstrate that in the next three to six months.
756.92 -> At least demonstrate, you know, research, what's called research doses of lower activity.
761.34 -> But how does this truly compare to what’s done today?
763.389 -> Well, we’d be looking at comparing this to devices like cyclotrons (aka particle accelerators)
768.639 -> and even nuclear reactors.
769.639 -> We’re just going to take nuclear reactors off the list for now for obvious reasons.
773.81 -> A hospital isn’t going to build out their own fission reactor (at least not yet).
778.02 -> Cyclotrons used for medical radioisotope production can range in size from small-sized cyclotrons,
779.02 -> at about 2 meters (6.5 feet) and a length of about 3 meters (10 feet), to larger ones
780.02 -> that can produce higher beam currents, at about 4-5 meters (13-16 feet) and lengths
781.02 -> of 10-15 meters (33-49 feet).
782.02 -> The larger facilities can produce a wider range of isotopes, but they’re _very_ large.
783.02 -> I was curious how many of these exist in the world and found that the International Atomic
784.02 -> Energy Agency (IAEA) actually has a database featuring over 1,300 cyclotron facilities
787.42 -> from 95 countries.
789.089 -> That’s 1,300 facilities for 8 billion people around the world.
792.72 -> And when it comes to power, large facilities can use hundreds of kWs of power, if not MWs.
797.79 -> It may not be a completely fair comparison at this point, but something like Astral’s
801.8 -> setup is far less.
803.17 -> How much do you need?
805.279 -> Couple hundred kilowatts?
806.35 -> No, 18 kilowatts per, well that system's 1.8 kilowatts.
809.91 -> And it's software controlled half that.
812.839 -> The double stack is 7.5 kilowatts.
815.48 -> But the high end systems that we built back in the day, and we're gonna use the exact
818.42 -> same power supplies, we're 18 kilowatts each.
820.779 -> So if we build five of those, it's gonna be 90 kilowatts.
824.86 -> And that's, I don't think we'll ever build a facility with more than five heads.
828.48 -> And then you've got, you've got cooling, which is roughly equivalent.
830.73 -> So that doubles the pass.
832.009 -> You kind double it, and then that's it really.
834.1 -> I forgot about the cooling.
835.52 -> Yeah.
836.52 -> You’re getting the benefits of less power to produce similar output in a small footprint,
841 -> so you can probably see why it caught my interest.
843.829 -> This kind of lives up to the tagline that shows up at the beginning of every one of
846.79 -> my videos.
847.79 -> “Exploring technology that impacts our lives.”
850.05 -> And during my conversation with Tom and what gets him excited about the potential here
853.009 -> … this is precisely why I traveled out to the UK on my own dime to visit them.
857.85 -> For the project that we're doing with the University of Bristol, we had something like
861.92 -> 13 letters of support from different clinicians in nuclear medicine.
865.54 -> Who said, wow, this would be amazing if we could have these in hospitals where we could
871.009 -> actually open up the menu of medical radioisotopes that we could use for diagnosis and treatment
877.029 -> of not only cancer, but cardiovascular diseases, detecting Alzheimer's and dementia, thyroid
883.43 -> cancer, all sorts of different types of tumors, metastases.
887.9 -> So that really, you know, wakes me up in the morning and gets me outta bed.
891.699 -> And to actually try and deploy this in, in a way that can impact people.
895.92 -> And that leads me back to how deceptively simple their technology looked while operating.
899.95 -> We have plasma, very stable plasma inside, so we can measure the neutron outputs from
907.079 -> here.
908.079 -> It's almost now.
910.29 -> Like one times into four, the second generated from the system.
917.18 -> Plasma is very stable inside here.
919.38 -> neutron output also is very stable.
922.06 -> So the, you can see some like dark, uh, color coming from the opening from the cathode here.
930.449 -> This is definitely more electrons are going outside from the, the potential well to the
937.85 -> bottom of the system, which will be very, very useful for our experiments for the lattice
943.621 -> confinement.
948.05 -> Thing will limiting us is only the temperature of the anode itself, which will be very hot
954.17 -> after like few minutes.
956.66 -> But, uh, in the future we'll make like a water jacket to cool down the surface of the anode,
962.38 -> which will make, uh, the system can run for hours without any film, without any degradation
969.5 -> for the input for the neutron output.
972.61 -> Speaking of neutrons, which is key to creating medical isotopes, there’s other uses too.
977.07 -> There’s also tritium production, which is a key ingredient for making the reactors seeking
981.37 -> to create net positive energy work … and it’s incredibly rare.
984.92 -> It’s more rare than deuterium, which is another key ingredient.
987.64 -> ITER, the world’s largest tokamak reactor that’s being built right now, is expected
991.699 -> to use 1 kg of tritium every year, but some estimates show we only have about 20 kg in
997.44 -> supply.
998.44 -> But as I pointed out, some forms of fusion produce tritium.
1001.38 -> For Astral Systems, their system running a deuterium + deuterium fuel mix for the reaction
1006.009 -> could be used for tritium production and research.
1008.519 -> Now, I’m only scratching the surface of what I talked about with these guys.
1011.269 -> I spent an entire day with them, I have hours of footage and audio recordings, a huge backlog
1015.8 -> of research papers I pulled to prep for my trip and pulling this video together, and
1020.519 -> this is just a tiny tip of the iceberg.
1022.28 -> There’s other potential applications for this technology that I’ve barely touched
1025.88 -> on, like tritium breeding for fusion research, detecting explosive devices, space exploration,
1030.98 -> and more.
1031.98 -> And even more exciting to me was that they’ve already achieved an order of magnitude improvement
1035.829 -> over the older IEC devices they’re repurposing for the test device.
1039.6 -> They have new cathode designs they’re getting ready to test that they’re hopeful will
1043.27 -> show another order of magnitude improvement.
1045.15 -> There’s still a lot of testing they have to do to see how far they can push their Multi-State
1048.96 -> fusion, but I’m definitely keeping tabs on how this progresses.
1052.59 -> So what do you think?
1053.59 -> Jump into the comments and let me know.
1054.82 -> And be sure to check out my follow up podcast Still TBD where we'll be discussing some of
1058.44 -> your feedback.
1059.44 -> Thanks to all of my patrons, who get ad free versions of every video.
1062.34 -> And thanks to all of you for watching.
1063.76 -> I’ll see you in the next one.
