Lab Notes
Build documentation, test results, and engineering notes — published in the open. This is what happens when concepts hit the bench.
The Materials Stack That Brings Hydrogen Back
Hydrogen lost to physics — pipeline embrittlement, volumetric density, and turbines tuned for natural gas. Three materials problems with three clear specs. QuantArm was built multi-domain — superconductors, thermoelectrics, dielectrics, photonics — and we are now adding a hydrogen-alloy lens to the same engine.
The Texas Grid Doesn't Need More Storage. It Needs Faster Storage.
ERCOT's large flexible load is up nearly 50% year-over-year. Most of the storage queue is solving the wrong problem. Here's what the load shapes actually demand.
The ERCOT Curve Has Broad Shoulders Now
The classic 2 PM Texas load peak has flattened into a wide plateau. Datacenters and bitcoin miners run the floor. Wind and solar run the middle. Batteries run the evening ramp. And the hydrogen story everyone was telling ten years ago is over — natural gas dispatches at $30/MWh, hydrogen-equivalent generation lands closer to $50, and the physics doesn't favor a comeback.
The ERCOT Battery Warranty Cliff and the Houston Regen Gap
Powin's Chapter 11 stranded warranty obligations on 17 GWh of utility-scale BESS. Tesla Megapacks are coming offline at Elkhorn. Houston metro operates roughly 700 MW of grid batteries with no commercial shred-and-sort or direct-regen inside Harris County — the nearest Texas processor is 250 miles north in McKinney, and the nearest LFP-capable line (Silsbee) doesn't come online until 2027. The OEM-credit math is moving.
Thermoelectrics and the Waste Heat Economy
Roughly two-thirds of primary energy in the US is rejected as waste heat. The thermoelectric materials that could capture even a fraction of it have spent forty years stuck below ZT ≈ 2. The bottleneck isn't physics anymore — it's manufacturing scale and the right substrate.
Superconductors: The Supply-Side Story
Fusion magnets, grid storage, MRI machines, photon-counting medical imaging, and quantum computers all want the same thing — high-temperature superconducting tape at production scale. Global REBCO output is measured in kilometers per year. The bottleneck is not the physics. It is the factory.
The Datacenter Water Floor
Hyperscale compute is colliding with chip fabrication for the same scarce resource — ultrapure water in stressed watersheds. The interconnect bottleneck and the cooling bottleneck are the same physics problem in different clothes. Both bend toward materials that don't exist yet at production volume.
Silver: The Connective Tissue of the Energy Transition
Solar paste, EV power electronics, REBCO tape stabilization, datacenter switchgear — every electrified industry of the next decade pulls on the same metal. Silver is structurally inelastic, the deficit is in its fifth year, and the USGS quietly added it to the critical minerals list in late 2025.
