The fusion physics-to-engineering gap — ignition (Q_plasma>1) is real, but the four outcome-layer constraints it never touches are where commercial fusion is actually decided
Evidence-first notes on bioscience and deep tech, at the edge of the lab and the market. Information only — not investment advice. Q values are always attributed to a device, series and denominator (scientific Q_plasma, engineering Q, or wall-plug Q are not the same number); tritium, materials and duty-cycle figures are attributed to the peer-reviewed…

Solid-state batteries — the “always 5 years away” story: the headline specs are real, but the bottleneck is interfaces and large-area ceramic-separator manufacturing yield, not electrochemistry
Evidence-first notes on bioscience and deep tech, at the edge of the lab and the market. Information only — not investment advice. All energy-density, cycle-life and charge-rate figures are attributed to the specific cell, sample and test condition reported; many are company measurements, company roadmap targets or trade-press claims rather than independently replicated, automotive-qualified data…
