What this site is
Sovereign Agentics is an independent site run by Raijin Hibiki in Anchorage, Alaska. It publishes two kinds of work: everyday browser utilities (word count, JSON, regex, diff, Base64) that never upload what you type, and a Power Abundance suite of space and energy calculators with the assumptions written in the open.
Most “free online tool” sites POST your text to a server and wrap it in ads. These tools are static HTML and JavaScript. Open view-source on any of them: the conversion, the physics, and the formatting happen on your device. That is the product. The blog is the other half — original write-ups on lunar ISRU, space-based solar power, data-center watts, and helium-3 mining math, each tied to a calculator you can actually run.
Premium products (PromptForge, SkillSmith, Sovereign SEO, and the rest) are one-time purchases that fund the free tools. Ads, when they appear, are how a solo publisher keeps 58 utilities online without a subscription. Read the about page, the privacy policy, or email Raijin.
Start with the writing, not the grid
Space-based solar power
Why orbit beats the ground four-to-one, what beaming actually costs, and when compute should stay in space.
Data-center power
2026 rack-to-campus numbers, PUE, and a calculator for a load you actually have.
Lunar helium-3
The real concentrations, the mining mass, and why the fusion hype does not survive the math.
Lunar ISRU
Oxygen from regolith, polar ice, and which process to optimize first.
Energy cost of AI tokens
Joules per token plus silicon per token — the physical floor of model pricing.
Solar to power the world
Terawatts, capacity factor, overbuild, and land area vs the Sahara.
