Day 2008 and From Running On A Dream to Running On Our Reactor

I’ve got to remember to keep tissues in my purse. I’m prone to crying when I’m proud. I am a crier by nature and the experience of pride and awe is becoming distressingly common. Woe is me right?

My very early bet on Valar Atomics (I wrote about it on Day 1145 but met Isaiah closer to day 900 early 2023) is paying off years, if not decades, ahead of my expectations. Never did I expect arguably the hardest operational bet in my portfolio to be such a fast breakaway hit. And I owe it to an executive order from Donald Trump and the efforts of patriotic Americans committed to regulatory reform. Which is crazy.

As it turns out, if the government gets out of the way of talented people, nay, if it demands that our state institutions help them, the impossible becomes possible in shockingly short order. The reports of America’s death are greatly exaggerated.

Today in front of a crowd of hundreds of investors, employees, and family members, I watched a reactor that might not exist without my first check, power an Nvidea Blackwell chip.

In a demonstration rivaling the greats (Ballmer, Jobs) Isaiah brought up NuclearWebsite.com and asked the audience to load it with him.

“Oh no it’s not loading?!!?” What’s happening? Do we have any electricity on site? Quick someone run the GPUs to the nearest electricity! Go go we can’t disappointment all these people!

And then the Blackwell is rushed into the Ward250 reactor. In real time the chip is run to the control room, gets hooked up and boom the website loads.

The first entirely privately funded nuclear startup was critical, stable, producing electricity and powering state of the art silicon.

We actually did it. The mad lads and ladies of Valar Atomics swept ahead of the competition in a frenzied year of progress (Day 1510) from seed round and Ward Zero to producing electricity to power GPUs.

After a twenty four hour travel marathon to get from the Ionian in the Mediterranean to the southern Utah desert, being back at the Valar Atomics reactor facility for a demonstration of this magnitude felt surreal.

Just a few weeks ago (Day 1969) the reactor was days away from being shielded and then fueled. We’d driven down to see her before she was wrapped up in shielding.

Proud first investors in front of Ward 259

Now not only has she gone critical (Day 1996) but I was able to walk into the running reactor room and see the live reactor for myself. The operator Ben (a former naval nuclear operator) seemed surprised and happy to see me. “Julie! Hi!” He exclaimed as me and the other early lead investors piled in for a tour.

I won’t lie it felt really cool that the team knows me on sight. The perks of being the very first believer (Day 1145) are worth the risk. Sure you get called crazy quite a bit, and only half the time does anyone mean the good kind of crazy, but sometimes you get to enjoy being right.

Jason Calacanis (also a master of the live demo) never lets anyone forget he invested in Ubers seed round. I get to brag I wrote Valar’s very first check

And while success has a thousand fathers and failure is an orphan, I’ll always enjoy the satisfaction of being the very first to take a chance on a long shot no one thought had any business even trying. And well they were wrong. And I was right. Not just right but really fucking right. I backed the long shot dark horse (somewhere around day 950) because my gut told me that the kid had the right stuff. And wow did he.

I only had a dim hint of exactly what we’d be seeing today as the invite said “Watts Next” cohosted by Nvidia and Valar. Clearly a number of us connected the dots because it was packed. The atom would power the compute and we’d get to see it live.

The team after the demo

Every existing investor, and quite a few later stage firms, came out to the middle of nowhere to see if these longshots had really done it. And indeed in just three years the impossible became reality. I’ve never felt prouder to be American. And clearly everyone around me felt the same.

This is a win for all of us. The families who gave up time with their loved ones so their loved one could pursue a dream. The policy makers and scientists who did everything in their power to prove we could make nuclear work again. The investors who wrote checks that no one else wanted to write as it was too risky.

And most importantly, it was a win for the team, led by the indomitable spirit of Isaiah Taylor. Their long nights and constant doubt paid off. The road ahead is long but no one is likely to doubt that we are serious contenders anymore.

I always say there was never a doubt in my mind. I had faith. Isaiah joked he had moments of doubts. I say I’m blessed that I got to be that first believer to say “I think you can do it and I’m going to help.”

And whenever he doubted that we’d make it (there are always near death experiences in any startup) it was my privilege to remind him that doing the impossible is just what we humans do.

Like Captain Kirk, I don’t believe in no win scenarios. I hope you consider joining me for more impossible long shots. Because sometimes taking the shot is worth more than anything else you will ever do.

Day 2001 and My Odyssey Continues

A vast somewhat intimidating vista is stretching ahead of me between two thousand days of writing every day and the possibility of reaching three thousand days of writing every day. One day and one post at a time right?

So like any sane woman setting out on a long journey, I ate a salad, had some protein and checked myself into a spa for a massage. No reason to start a long journey exhausted right? I need to pace myself.

I got a pedicure to immediately turn restoration to grooming necessities, but one can’t keep pool blue toenails all summer. Not every day is spent on the Ionian. Some days are spent at nuclear facilities in steel toed boots. Other days are spent in kitten heels inside conference rooms.

Just in case anyone does need to see my toes after those scenarios, I try to maintain a tidy nude set of nails. Isn’t it strange what expectations we have for women?

I may work remotely, at odd hours and in odd locations that allow the occasional eccentricity, but at any moment I might need to be on an airplane headed to parts unknown. You only get to be so weird when you have big goals.

In this case, next week I’m headed to a desert town and then a state capital. That’s state is becoming a more regular occurrence in my life. That’s a pretty big privilege for me.

Being a supporting player in a number of larger endeavors gives me the chance to add additional gravity if and when I might be useful. Even if it is just showing up as a cheerleader. I love trying to convince smarter, better capitalized and better connected players than me that indeed it is my startups are the winners in the grand game of macro-cycles.

I wrote that the world was getting to be a lot more chaotic when I first started this writing journey. Now that’s common knowledge. Then and now, I care about adaptability to this increasing complexity. This has turned out to mean compute, energy and decentralization.

The strength of your network is in the flexibility and foresight of its nodes. And I hope I remain a trusted node at the forefront of our long journey as a species for as long as I serve us well. I’ll carry on this Odyssey till then.

Day 2000 and Don’t Stop Believing

Well I’ve done it. I have written and published to the internet a blog post every single day for two thousand days in a row. So I am going to toast myself to a job well done.

In earlier milestone posts, I was always surprised I’d made it, but now the harder thing to decide is if or when I’ll stop, not if I’ll keep going.

Half a decade goes by a lot faster than you think. The accomplishments actually do add up if you keep yourself pointed in the right direction.

In a personal capacity, we got ourselves to Montana, set up a life that let us live the way we’d always dreamed and invested in the future we wanted to see.

From a civic perspective during that time we helped pass meaningful reform in housing, testified for crypto rules of the road and worked to ensure Montanans have a right to compute.

A new era of networked algorithmic power has been building for many years and our rights to use compute as we see fit is bolstered by our 1st, 2nd and 4th amendments.

From an investing perspective, we have been first in Solana’s most crucial infrastructure player Squads. Because yeah crypto is going to matter a lot in an artificial intelligence age. We have stuck to our core mission of adaptation by backing the tools needed to benefit from our new AI speed run.

And yes we care about open source. From vector databases to inference labs to experimental dueling models, we have snuck into some strange experiments. And oh yeah we were the first check in a small modular nuclear reactor that is winning the atomics renaissance race (at least this week having achieved criticality).

There have been a lot of failures in those years though oddly not investments or policy. I have battled health issues and fought to not just maintain working capacity but to gain back the capacity I thought I’d lost forever.

I did woo woo whacky things from PEMF and HBOT to peptide stacks and traditional biologics. Thanks to the horrors of hormones and steroids I was early to GLP1s and made some good investments there too.

Maybe I’ll tag all of this more cleanly later but I do think it’s important to remember the days are long but the years are short.

Get on the airplane. Go meet up in person. Buy that dream house. Build a solar array and a sauna. Do wildly romantic things and go to galas. Say yes to more.

And open your heart to the heroic efforts others are also putting into making our lives and our world better. We live among every day heroes. And yeah lots of bad shit has happened in this time too. My father died. We failed for five years straight at getting a visa for a close family friend.

I am aware of the shitty compromise we all make to survive. But you have got to hold on to that feeling. So yeah on day 2000 I think I’ve earned the right to be corny as hell. Don’t stop believing.

Day 1996 and Criticality at Valar Atomics

I am going to be scattered and long winded so please excuse my exhaustion and joy, as I have used up all of my focus in the excitement of a truly incredible moment that represents years of work.

I watched “our” reactor go critical on a livestream with the Valar team. Yesterday midafternoon on mountain standard time (around 1:45am for me on GMT+3) in the beautiful desert of Orangeville Utah, Valar Atomics took its Ward 250 critical for the first time.

Mission Control at Valar Atomics

Moments ago, Valar Atomics took Ward 250 critical for the first time. This fulfills President Trump’s EO 14301, which called for 3 advanced reactors to go critical by July 4th.

This is our second criticality as a company, and an important step toward our goal of power by July 4.

This is a historic moment and the culmination of two years of work on the part of the Valar Atomics team. This is the most hardcore, intelligent, and driven people I’ve ever had the privilege of working with; which will be seen as we begin power ascension in the coming days.

Our mission at Valar Atomics is to make abundant energy for all mankind. The best way to make energy 10x cheaper today is to mass-scale nuclear fission. We began our mission by creating WardZero, our fully functional thermal prototype. Next, we took the NOVA core critical.

Today, we took the next step: criticality in the Ward 250 test reactor. Ward 250 is a TRISO-fueled High Temperature Gas Reactor (HTGR) designed for simplicity and scale, and is the first nuclear reactor ever air-lifted by a C-17.

We’ve been honored to be become part of the community in Orangeville, Utah, the home of Ward 250. Many thanks to all of our government partners who made this possible: hundreds of individuals across the Trump administration, the DOE, the DoW, and the government of Utah.

The list of individuals who have spent their time and energy and talents to accomplish this feat is too long to list in one post, but I am incredibly grateful to all of them.

Isaiah Taylor of Valar Atomics

I am one of those individuals who spent their time, energy, talents and capital to accomplish this incredible feat. Investing in Valar may well be the greatest accomplishment of my life.

You see I am Valar’s very first investor. Yes I mean I wrote the very first angel investment check from my small venture fund.

I know it’s a little crazy that a weirdo like me should be investing in small modular nuclear reactors built by brilliant young Zoomers and equally brilliant old timer experienced nuclear engineers, but weird is how I invest with chaotic.capital.

Crazy but possible makes complete sense to me. So I said he’s. And we chewed glass for a few years working towards the possible, while everyone told us it couldn’t be done.

Through the magic of Twitter DMs, I met Isaiah before he had even started Valar. He was working on another startup I didn’t love but I knew immediately that I loved him as a founder.

I was so impressed with his intelligence and his capacity to learn quickly. He had that ineffable “it” quality that all founders possess in some measure. He took feedback well but had a firm backbone. He listened to one piece of advice I gave him and based on that decision alone, I told him I’d back anything he did in the future and I meant it. I’ll admit I didn’t expect it to be “I’m building a nuclear reactor” but I am true to my word.

Fast forward several years and here we are. Just a few weeks ago I was racing through the desert to see the reactor our first check helped build the day before it was encased in shielding in preparation for criticality. It will be a memory I will treasure forever.

A few months ago this hanger didn’t exist

We’ve been there for every step of this amazing journey. It was an objectively insane thing to invest in. Yet the more time I spent with Isaiah the more convinced I was that he was a generational talent. The best part of being first is the opportunity to spend lots of time with a founder before anyone else learns of their genius. I learn as much from them as they do from me. And Isaiah is a quick study.

I wrote the check and went about the long grueling process of convincing others they should invest alongside me. It wasn’t easy. We got told no a lot. Failure lurked around every corner. People ranged from outright hostility to tempered skepticism. There were moments when defeat felt very close.

There were hard times. A lot of glass chewing. I never wavered in my belief that Isaiah would get it done. Alex and I were blessed with the opportunity to invest more and gladly wired in additional capital when others couldn’t see as far as we did. This may well be a career defining investment for me. I intend to keep putting in whatever Isaiah will allow us to invest.

Now three years into this journey, it’s clear to everyone that Isaiah is the talent I always knew him to be. I may have been first but I won’t be the last. This is the kind of company investors dream of finding early and Isaiah is a leader I am proud to follow. Valar is racing towards the kind of future I want to build for the next generation. Abundant cheap fuel can power a better cleaner world for all of us.

And to everyone who said it couldn’t be done, or that it was too early or too risky to invest in something as crazy as nuclear, please let me invite you to join us now. There is much more to be done. We will need all the talent and capital we can get to win this bright future for America and for humanity.

Day 1969 and A Very Nice Day

I am in the middle of the Utah desert returning from a site visit to Valar Atomics. If you have the means to tour a nuclear facility I highly recommend it. It is so choice. That’s Ferris Bueller for the Zoomers.

I’ll use another choice line from the John Hughes classic to illustrate how gratifying it has been to drive a remote Utah town for a chance to see our investment in action.

Life moves pretty fast. If you don’t stop and look around once in a while, you could miss it. – Ferris Bueller’s Day Off

We hadn’t planned to drive down to the Ward 250 facility after Abundance Institute’s Operation Gigawatt. Life is busy, it’s a holiday weekend, I’m flying out to part unknown from Montana in two days.

But what’s another three hours on the open road when there is one of America’s sustainable energy labs and a tour from your favorite engineers on offer? Yes they are all working this weekend. They have a deadline for July 4th that’s pretty important. It’s crazy that this wasn’t in my itinerary in the first place if I’m honest. What a way to kickstart the summer.

Getting up close to “our” reactor is a privilege I never conceived of experiencing. I’ve been lucky enough to invest in some very cool things over the years, but to actually place a bet on a serious industrial effort and have my choice end up at the forefront of a major national push for nuclear energy? Not a thing I saw coming.

So in the hustle of the moment, I am glad to slow down and admire that it is actually possible to do things. That’s a very nice day to have. Yes that’s a Day 69 joke.

I’ll treasure this moment forever. Even if we fail, at least we tried. And who wouldn’t want to put yourself on the line and try when it’s something that matters this much? So we speed up to slow down and see. Because it’s true if you don’t you might just miss it. So yeah it was a nice day.

Day 1968 and Abundant Optimism

I’m in Utah with some of the most optimistic people I’ve ever encountered. And it feels so good to be amongst others who believe our problems are tractable, it is our responsibility to solve them, and that we all win when we pursue a positive sum approach together.

The Abundance Institute hosted the Operation GigaWatt Summit in Park City to bring together entrepreneurs, engineers, financiers, legislators and policy experts to discuss America’s energy needs.

I was lucky enough to be invited to the gala where one of our founders Isaiah Taylor gave an incredibly uplifting fireside chat

As some of my longtime colleagues know, I was the first check into Valar Atomics. It was a leap of faith to invest. At the time, we were in the doldrums of negativity towards capital intensive industrial efforts, from both state and capital.

Yet I saw in Isaiah a force that neither leviathan nor fund manager would wish to hinder. I also happened to believe that every other technological trend that was booming rested on our capacity to power it. So I did everything I could to support him in his efforts, including write few more checks. And thank goodness I did as my what a difference a few years make.

Utah’s Governor Cox and Isaiah Taylor of Valar Atomics

To see Isaiah on stage with Utah’s Governor Cox amongst a crowd of hundreds speaking on a vision that a mere three years almost no one thought was a good idea (well except us) is testament to the work and faith of hundreds of men and women.

Many other amazing companies are pursuing a vision to produce abundant clean fuels and I myself believe we will need every one of them. I’m just glad that my crazy bet happens to be running full steam ahead in front.

From artificial intelligence & medical research to new home construction and industrialization, all our biggest opportunities will win on energy costs. Regular people need cheaper, cleaner, more sustainable energy. Our needs can’t be met with what we’ve got. We need nuclear in that mix.

And it is a choice to embrace abundance and not scarcity. A zero sum mentality will not get us where we need to go. Not in America, not on our home Earth, and certainly not in the stars. I believe with effort and ingenuity our best days are not behind us but can, indeed must, be ahead of us.

Utah is focused on delivering to the public by gaining its truth through transparency and accountability.

I’ve come out of the last two days refreshed and filled with positivity as I’ve seen sincere people dedicate themselves to finding solutions to our pressing problems. I was able to see much beloved friends, treasured colleagues, and it was family friendly so I brought along my husband too.

Here we are waiting for me to record an interview with MTS who very kindly asked me about Montana’s right to compute law.

If you care about a future that’s not fighting over what’s left, but building something that makes more for all of us, I hope you consider supporting the work of the Abundance Institute.

And also Montana’s right to compute law.

Oh and if you have a chance to invest in the future of nuclear energy I hope you pick Valar. As we are fond of saying in El Segundo circles, we are going to win.

Day 1965 and Don’t Drown in Manic Waves of Algorithmic Surf

It’s hard not to feel like you are drowning when you open up a newsfeed. Every day you are watching people on tilt across every topic and demographic. Is this the singularity?

The doomers and Luddites are being courted by money with shadowy religious grants to “prepare for the dangers of super intelligence.”

Competing political lobbyists in all nations are desperately trying to outscream the noise of crashing feeds as news refreshes with propaganda optimized to reach you.

From celebrity individual contributors making moves to worries about the star struck minds of the managers of the biggest funds, it’s all happening at 1000x the scale of sense.

I go outside and I breathe in the cool Montana air and I am settled by the almost impossible beauty of the mountains out our pasture. If you hike out to the public fields before the canyon you can see the whole valley spread out before you.

Public lands out my backdoor that look like a Microsoft Windows Screen saver

After a weekend snowfall, the grass is coming in spring green and the sky is as bright a blue as a screensaver. The resolution of reality has yet to be surpassed but I don’t know for how long that will be true and if it’s even true for most people.

It’s impossible not to feel as if one is being torn apart as each successive wave of new information comes at you. It’s all on tilt. It’s all faster. It’s all getting better. Or is it all a horror? It depends on the wave.

If you refresh at the wrong moment it’s all getting worse. What about the Vatican and their new encyclical from Pope Leo? Industrial Revolution Leo? Nah Intelligence Revolution Leo. Anthropic is sending a vegan atheist as their emissary.

“You best start believing in singularities!” Cthulhu Dread Pirate by way of ChatGPT Image 2.0 reminds us as we just might be in one. Do we dare laugh back? “This is the day you will always remember as the day you almost caught Captain Jack Sparrow (in a Singularity).”

In other house keeping news, I’ll be driving from the mountains to the desert to participate in the Operation Gigawatt Summit in Park City Utah later this week. If we are accelerating into a new future of intelligence, someone has to provide the power and the compute. And that’s my crew. Lots and lots of white boys apparently.

Day 1917 and Bragging

My brain feels pretty scrambled at the moment. I wish I could say it was over easy but I’m clearly closer to fried than coddled at the moment. Yesterday had some big news. Valar is prepared for a long slog and that means on paper I’ve got a unicorn and a fund returner.

There’s nothing quite so satisfying as becoming big enough that instead of listing the founder and the team, they mention the celebrity investors.

It’s good that people know we have dry powder for an important mission, just as energy insecurity becomes a real concern, along with all of the cascading effects of side products and elements that are part of the hydrocarbon processing chain. Don’t worry. They’ve got a plan for nitrogen if it comes to it.

And obviously I want to brag, as do all of the other people who took a risk on this exceptional team, especially those who wrote multiple checks (we followed on three times) when it was unclear how far we could go and how fast it could be given regulatory hurdles and funding constraints. Those are now gone.

I do feel like I paid a number of social consequences for being a loud mouth and also generally being anti-consensus during the first few years. And I am glad to have paid that price. Real reward comes from real risk.

I felt we had not adequately addressed American energy independence, clean energy, renewable energy, or any of the many effects of our rampant demand for energy.

I do believe that carbon heats the planet and we have to address it in a way that meets our demands and gives us abundant supplies. I thought well how we could possibly serve it in a way that is sustainable and clean without nuclear?

And I’m as surprised as anyone that the Republicans are the ones championing this but we’re in a place where it’s very clear that we have industrial needs and a geopolitical context that require us to go much faster and invest much more deeply in the solutions that we’ve put off for so many years.

I didn’t get into technology to do some set of financial arbitrages or eke out an extra few dollars so I could have status in the world. I know it’s naive but I’m not very transactional and I do it because I think it’s the right thing to do.

We need to slowly push the markets towards funding the things that are necessary and not just the things that give extra capital to people fighting for status and power. I hope that I can look back on the work I’ve done and feel proud that I tried.

Thanks to this blog God knows I’ve got the receipts for it. We’re barely out of the first quarter. Not even confident we’re at halftime. There’s so much work to be done but I feel like I’m playing the right game.

Day 1898 and Please Copy Our Homework

Today has been a very gratifying day for a very strange intersecting set of reasons. You may know that I have spent several years working to pass a “right to compute” law in Montana. It was signed into law in August of 2025 by Governor Gianforte.

I was so grateful that a campaign I initiated became not only become a bipartisan policy but a law supported by many Montana citizens & legislators. Now to see it go national not only model policy for the American Legislative Exchange Council but now have a second state, New Hampshire, pass it in their house, gives me indescribable joy.

Just forty eight more states to go. Though I believe it’s going to be an uphill climb as the topic of artificial intelligence has well and truly become politicized which makes stating simple cases of shared values much harder.

Except this isn’t really about artificial intelligence. Compute is a much broader and bigger thing than AI. It’s the stuff of the modern world. But that doesn’t mean we can’t apply what we know to be core American values as the lens through which we see it. Indeed it’s crucial we do.

Last year people could easily see that this was a sensible law that reflected our American values. Because of this sensible approach “the right to compute” is a winning coalition. It was bipartisan. So naturally it became a culture war.

I urge you not to adopt that frame. The right to compute speaks to American’s most cherished beliefs. Recognizing that it is not a novel legal theory. It is the application of the Constitution’s oldest commitments—to expression, to property, to liberty against government coercion

Even if you do not understand how all of its parts work, most understand that the entire digital world, in its constituent parts, is mathematics executed on physical hardware.

When government restricts computation, it does not merely regulate an industry. It restricts the tools through which people think, express themselves, and make use of their own property. Through that lens it’s clear we as Americans decide ourselves how to use it.

I hope we can remember this as the world changes and political actors look to change your mind. I do expect this to become a very complicated and uncomfortable position to have staked out.

Yet I feel confident that we will be able to make the case that this is not only the most American way of handling our future challenges, but is also practically the best way to bring abundance in a chaotic world. America is a land of reinvention that changes material conditions. We need not seek doom.

I believe that I have articulated that vision over the last five years of writing and investing so you can see my revealed preferences. I called our fund chaotic.capital for a reason. It’s hard, weird, difficult and scary but it’s also possible to be a lot better in the digital world such that we can use those gains to make the material world better. We can be more than productive primates with jobs

From nuclear energy to compute, this is what I believe and where I have put my time and money. We are organizing our world of atoms through the power of compute. And that can bring about a materially better world for everyone. Which I want.

I have been thrilled to see so many different people come together around the basic premise that we are empowered to do things.

We can lean in to the accelerating changes, all while holding fast to the reins of the values that built America, so that we may steer ourselves to material success.

Travis Kalanick of Uber may be among the best founders to have ever played the venture startup game. Today he has espoused our thesis & reinforced the work of my friends & founders. To see a cultural program written by a big coalition be part of his return to startup life (though he was never gone) is validating. We’ve found a rallying call.

The way forward is through the application of math on real problems. We can dramatically reimagine outcomes and the pace at which we do it. It’s scary and will look different but our grandparents lived through a lot of change too. Their grandparents as well. It’s the human condition.

I believe all of this is grounded in a philosophical foundation that is a recommitment to America’s core constitutional values. We are free to make things. And sometimes, when we apply ourselves, the world really does change.

If you are a canny socialist thinking look at this useful idiot for capital, I am honestly surprised that dialectical materialism has become so disliked by its own movement. If states with conservative libertarians can see that culture only changes when material conditions improve why don’t you want to improve them? Please feel free to copy our work as we have studied yours. You can find model policy here.

Day 1873 and Flying A Micro-Reactor on a C-17

I spent most of yesterday on an airplane. I flew nearly 12 hours along the polar routes to go from Heathrow to America’s west coast. I flew British Airways and was disinclined to spend the many pounds for internet access.

Alas this meant I missed the rollout of the joyful flight of one of my favorite investments. Valar Atomics began its journey from California to Utah just as I too was flying. Me and the reactor I angel invested in were both up in the air like bluebirds and sunshine.

HILL AIR FORCE BASE, Utah, Feb 15 – The U.S. Departments of Energy and Defense on Sunday for the first time transported a small nuclear reactor on a cargo plane from California to Utah to demonstrate the potential to quickly deploy nuclear power for military and civilian use.

The agencies partnered with California-based Valar Atomics to fly one of the company’s Ward microreactors on a C-17 aircraft — without nuclear fuel — to Hill Air Force Base in Utah. Via Reuters

I tear up just thinking of the incredible accomplishments of millions of people coordinating together across centuries that these technologies represent.

It’s easy to think of ourselves as being small in the vastness of time and space. I almost cannot believe I was handed such gifts in this life, but I can claim a small but early part in Valar’s story.

U.S. Energy Secretary Chris Wright and U.S. Under Secretary of Defense for Acquisition and Sustainment Michael Duffey on board a C-17 cargo plane that transported Valar Atomics’ Ward nuclear microreactor from March Air Force Base in California to Hill Air Force Base in Utah, at the Hill Air Force Base in Utah, U.S., February 15, 2026. On the right, with the American flag and the Valar logo on his jacket is our CEO Isaiah Taylor

Just a little over three years ago I sent Isaiah a message on Twitter. We had a lot in common and I felt a kinship with this young entrepreneur. It was before he had even begun the incorporation work on Valar. He was working on something else, but I trusted his quiet intelligence and admired his humble inquisitiveness. We kept in touch as he mapped out his path.

His lack of ego instantly marked him as special, as it meant he could hear even the hardest criticisms. His fortitude was clear. He could incorporate what was necessary into his mission, a skill usually developed much later in life.

It’s rare to build trust so early on, and yet we both did. I told him I’d back anything he did so long as he was the CEO. Little did I know just how lucky I would end up as his very first backer.

You might think you will have doubts in high risk early stage investing. But I’d be lying if I said I didn’t believe in him from day one. I knew he was on a mission bigger than any of us. I knew it and he knew it. For God and country as they say.

That faith was required, as it was tested in rapid succession again and again over the next three years. Chewing glass is part of every startup. Even when you go as rapidly as Valar has gone, there are harsh conditions, brushes with death, and moments of utter joy in between.

Not only did we write a first check in the angel round, but in tight spots before the seed closed we wired follow on within minutes when a concern about a cash flow question arose. We put together special purpose vehicles. Nothing could jeopardize this mission. I’d invest more if I could.

We weren’t always the ideal investors as we struggled to showcase to bigger and better firms our conviction. Not too long ago it was all about being asset light and software as a service. Thankfully the execution always outshone the skeptics and we were ahead of the times. And while the skepticism was fierce, Isaiah never wavered. Neither did I.

Today is day 1873 in my daily writing log. I first wrote about Isaiah on Day 1145 which means somewhere around day 780 or so is likely when we first met. I wrote on day 1510 almost a year ago about their seed round and the first successful thermal testing. On day 1721 they broke ground in Utah.

And you can better believe that I am looking forward to July 4th this year. We promised the president we’d be turning on the reactor, so there is much to be done between now and then.

Even the Department of Defense (War?) is writing swan songs about Valar from the Pentagon Twitter account

At March Air Reserve Base, California, yesterday, a next-generation nuclear reactor was loaded aboard a C-17 Globemaster III aircraft for transport to Hill Air Force Base, Utah. The reactor will eventually head to the Utah San Rafael Energy Lab for testing and evaluation.

The Ward 250 is a 5 megawatt nuclear reactor that fits into the back of a C-17 aircraft could theoretically power about 5,000 homes.

For military use, such a reactor could provide energy security on a military base ensuring the mission there need not depend on the civilian power grid, and in military operations overseas, such reactors would mean U.S. forces could operate without concern that an enemy might cut fuel supplies.

A reactor such as the Ward 250 also means greater energy security for the entire United States. It is firmly in line with President Donald J. Trump’s executive orders to reshape and modernize America’s nuclear energy landscape.

The president signed four executive orders designed to advance America’s nuclear energy posture, May 23, 2025. Those include “

Reinvigorating the Nuclear Industrial Base,

” “

Reforming Nuclear Reactor Testing at the Department of Energy

,” “

Ordering the Reform of the Nuclear Regulatory Commission

,” and “

Deploying Advanced Nuclear Reactor Technologies for National Security

.”

Michael P. Duffey, the undersecretary of war for acquisition and sustainment, said the partnership between the War and Energy Departments is critical to advancing the president’s nuclear energy initiatives.

“It’s clear to me that advancing President Trump’s priority on nuclear energy depends on close coordination between the Department of Energy and the Department of War,” Duffey said. “This partnership ensures advanced nuclear technologies are developed, evaluated and deployed in ways that strengthen energy resilience and national security.”

The future of warfare is energy-intensive, he said, and includes AI data centers, directed-energy weapons, and space and cyber infrastructure. The civilian power grid was not built for that, and so the War Department will need to build its own energy infrastructure.

“Powering next generation warfare will require us to move faster than our adversaries, to build a system that doesn’t just equip our warfighters to fight, but equips them to win at extraordinary speed,” Duffey said. “Today is a monumental step toward building that system. By supporting the industrial base and its capacity to innovate, we accelerate the delivery of resilient power to where it’s needed.”

Secretary of Energy Chris Wright said that with small reactors like those transferred from March Air Reserve Base to Hill Air Force Base, the United States is aiming for a nuclear energy renaissance.

“The American nuclear renaissance is to get that ball moving again, fast, carefully, but with private capital, American innovation and determination,” Wright said. “President Trump signed multiple executive orders that have unleashed tremendous reform of all the things that stopped the American nuclear industry from moving.”

Part of that effort, he said, will mean that by July 4, three small reactors will be critical — or running smoothly.

“That’s speed, that’s innovation, that’s the start of a nuclear renaissance,” Wright said. By
