A Closed-Web Geothermal Architecture for Phased Scaling with Mitigated Seismicity Risk: A Preliminary Modeling Study

Next-generation geothermal systems are advancing along two primary pathways: Enhanced Geothermal Systems (EGS) that create convective reservoirs via hydraulic fracturing, and closed-loop systems that extract heat via conduction. While EGS offers high energy yields, it carries risks of induced seismicity. Conversely, conduction-based closed-loop systems mitigate seismicity but face challenges related to thermal drawdown and, in the case of multilateral designs, complex well-to-well intersections...

Symbiotic Expansion

The Finite Inventory

Civilization rests on a finite timeline. With current extraction methods we have roughly 50 years of oil, 100 years of uranium, and 150 years of coal. Even the planet's internal heat is a finite resource driven by primordial cooling. We are racing against a thermodynamic clock.

Continuity of Life

The goal is the continuity of life in harmony with Earth. Modern society's issues pose threats more pressing than those numerical constraints. We must leverage these dense energy sources to build a bridge to a brighter future for everyone.

The Planetary Engine

Long-term expansion requires energy on a cosmological scale. By responsibly extracting geothermal heat, we align with the geodynamo that generates Earth's own magnetic shield. We must utilize the power and tools available to us to secure our timeline, explore other worlds, and free humanity to pursue the greater truths of the universe.

"We seek not to conquer the universe, but to understand it, and to ensure that life remains to witness it."

Alpinism

Philosophy of Ascent

Alpinism is a practice of freedom and a proving ground for the impossible. It is one way I test the strict boundaries of thermodynamics, risk management, and physiological endurance in high-consequence environments.

From 24-hour continuous pushes to complex technical descents, the mountains demand absolute self-reliance. I believe that collective safety is built on individual accountability, ensuring that every member of a team possesses the competence to lead and resolve critical situations independently, eliminating reliance on any single point of failure.

This discipline sharpens my clarity and drive, reinforcing the reality that seemingly unreachable summits, in nature or in engineering, are within grasp if we rigorously prepare the mind and body to reach them.

The Cascadia Project

In 2025, I applied this ethos to execute human-powered ski descents of all five Washington volcanoes in a single season.
