A Roadmap for the American Nuclear Golden Age

Today, President Trump established a new policy for nuclear energy which represents a fundamental shift from the last 45 years of stagnation. This shift is codified in four executive orders.

Let's dig in! Image First the history. The United States was once the undisputed leader in atomic energy. We created the world’s first reactor, and piloted every major reactor architecture since, from LWRs to to molten salt to my own favorite, the HTGR.

It took about 10 years to get to Valar Atomics. I began pursuing this question in earnest when I was 14. In 2 years I had an idea of the problem, which I still believe. But it took 8 more years to build an accurate mental model of the industry and of reality, then find a solution The process generally looked like:

1. Describe my mental model in writing
2. Make specific predictions about what I expect to find in reality
2. Spend a few months Googling, reading, and talking to people with experience
3. Figure out why my predictions were wrong
4. Repeat

This morning Samo Burja went on a podcast with some very hard words for nuclear energy. I want address them immediately. But not because he's wrong.

Instead, because he got a few CRUCIAL things right; and the hard truths he tells go to the core of why I started Valar Atomics. Burja argues two things:

1. Energy demand is unexpectedly low.
2. In order to make anything cheap, you need to make thousands of it. Nuclear is too powerful and energy demand too anemic to justify thousands of reactors. There's no market!

(he's right; I'll get to that shortly)

Today I'm excited to unveil Valar Atomics!

Valar is my master plan to make energy 10x cheaper in 10 years by pulling oil and gas out of thin air with nuclear fission.

This will untether energy from climate and politics, fuel American industry, and unlock a new era of growth Image All of our greatest ambitions — interplanetary life, artificial intelligence, robotics, and biotech — need energy that is orders of magnitude cheaper and more abundant than we have now.

In 1970 we stopped our century-long march of making energy cheaper.

I'm here to restart it. Image

Any examples of this @cramforce? docs mention the possibility as well, but attempts have failed. I need sls here rather than edge because @LangChainAI doesn't support Edge Runtime yet; stuck btwn rock and hard place: no streaming on sls, no Langchain on edge 😵‍💫 @cramforce @LangChainAI Here it is in docs as well; goes on to talk about ReadableStream response on edge, but highjacking the response on serverless does not work vercel.com/docs/framework… Image
