A New Paradigm in Compute: Thermodynamic Intelligence

After almost a year of involvement with the Extropic team, it has become clear that their talent and insight are unparalleled, encompassing a unique set of competencies allowing them to reimagine compute. This comes at a major moment for Extropic as they recently unveiled the existence of their printed thermodynamic microchip1 and circuit board. This fundamental milestone is only the beginning of Extropic's journey towards civilizational impact.

The Answer to the End of Moore’s Law - Thermodynamics

For over half a century, computing has advanced at an exponential rate, following the densification of transistors along the trajectory observed by Moore’s Law - the doubling of transistors on a microchip every two years (initially every 18 months) outlined in Gordon's aptly titled “Cramming More Components onto Integrated Circuits.”2 The question now is: what happens when we can no longer cram more transistors into a chip? 

The golden age of transistor growth is now reaching the constraints of atomic scale, EUV printing limits, and Nyquist noise.3 As semiconductor fabs struggle to push nanometer accuracy and AI workloads drive energy demands to unsustainable levels, the industry has responded by continuously scaling costs and input investments—the solution has been simply more chips and more energy.

Enter Extropic, a company rewriting the fundamental rules of computation. Instead of fighting against the thermal noise that limits the continued processing gains of traditional semiconductors, Extropic harnesses it.

Powering a New Era in Electric Flight

H3X has built ultra high-performance electric motors that promise to enable electric aircraft, as well as sustainable marine and industrial transportation. These electric propulsion systems have been delivered to aerospace heavyweights and have found strong demand across aviation, marine, heavy industry, defense, and power generation.

H3X’s electric propulsion systems provide the foundational technology for the electrification of aerospace and marine transport, an evolution that is just beginning to unfold.

Over the past three years, I have witnessed the founding team display a phenomenal speed of innovation. They rapidly commercialized their technical advances into market-leading electric propulsion systems, using key breakthroughs to develop a series of products with numerous industry applications. This has resulted in contracts won with NASA and the US Air Force, as well as partnerships with a range of innovative aerospace companies.
