WHAT IT’S REALLY ABOUT
Tesla alumni target minerals, grid upgrades to reindustrialize America fast
- AI leadership is constrained less by algorithms than by “atoms”: materials, energy generation, and grid capacity to deliver power where needed.
- Mariana Minerals aims to close America’s critical-minerals gap by vertically integrating mining and refining and using software (LLMs and reinforcement learning) to speed design, construction, and operations.
- Heron Power targets the grid’s slow-moving core by applying modern power semiconductors to build solid-state transformers that improve monitoring, control, and scalability for data centers and renewables.
- Both founders contend the US can build quickly when incentives align, but permitting, local “yes/no” dynamics, and fragmented supply chains often slow deployment more than labor costs.
- They call for durable industrial policy and coordinated infrastructure planning to unlock private capital, co-locate supply chains, and accelerate grid and minerals build-out domestically.
IDEAS WORTH REMEMBERING
5 ideasAI competitiveness hinges on energy, materials, and grid throughput.
The discussion frames AI dominance as dependent on mining/refining capacity, manufacturing scale, and the ability to transmit electricity to new loads like data centers—not just better models and chips.
Permitting isn’t the only bottleneck—execution speed after approval is critical.
Caldwell argues the US remains slow at designing, building, and ramping mineral projects even once licensed, with multi-year timelines to construct and reach steady-state production.
Autonomy is positioned as the lever to overcome scarce industrial know-how.
Mariana’s bet is reinforcement learning to run refineries and mines amid variable feedstocks and thousands of daily operational decisions, reducing dependence on a thin domestic talent pool with legacy expertise.
The grid’s core remains largely mechanical and under-instrumented.
Baglino contrasts rapid innovation “at the edge” (EVs, charging, storage) with minimal modernization “on the other side of the wire,” leading to fragile, overbuilt systems with limited control and monitoring.
Power semiconductor advances are ready to be deployed on the grid.
Heron Power plans to use silicon carbide–enabled power electronics to replace traditional steel/oil/copper-heavy transformers with solid-state transformers for data centers and large energy sites.
WORDS WORTH SAVING
5 quotesThe US is 50 years behind on critical mineral supply. We are too slow at designing, building, and ramping up new minerals capacity even after we have license to operate.

AI dominance and re-industrialization more broadly are physical projects. They are energy projects. They are mining and refining projects. They are manufacturing projects. They are grid-scale projects.
— Erin Price-Wright
Even though there's so much innovation happening at the edge of the grid, on the other side of the wire, there's really been no change.
— Drew Baglino
We're making a big bet on autonomy in refineries, where we use reinforcement learning to actually remove humans from the loop in determining how refineries operate.

If the outcome is worth it, like, we-- that-- Tesla will, like, fight through the challenges of getting to that outcome.
