Capability Expansion: Why AI Should Multiply Our Ambition, Not Replace Our Jobs
We don't suffer from too much human capability, but too little. AI isn't a threat to labor; it's the tool that finally lets us solve our biggest problems.
Quantum
Can Qubits Be Cloned? How Encryption Refines, but Does Not Break, the No-Cloning Theorem
IBM hardware cloned a qubit into 77 encrypted copies using 154 qubits, yet only one is ever readable. The no-cloning theorem is refined, not broken.
Science
Ultrasonic Full-Body Scans, Wellness Spas, and the Science Behind the Spectacle
Ultrasonic CT uses no X-rays, and the prototype runs about 20 minutes, not the 60 seconds claimed. We separate the science from the pitch.
Energy
Boiling Liquid CO2 as a Turbine Working Fluid: Can It Replace Steam?
CO2's 31°C critical point makes condensing CO2 turbines feasible only with cold sinks. Why sCO2 Brayton (10 MWe STEP Demo) leads the field.

EHang's EH216-S and VT35: Inside the World's Only Certified Pilotless Passenger eVTOL Program
EHang holds the world's only certified pilotless passenger eVTOL. We assess the EH216-S, the VT35, and whether autonomy can scale beyond China.
Batteries
Sand Batteries and Thermal Energy Storage: Viability, Economics, and Industrial Decarbonization Outlook
Decision-grade analysis of sand batteries, thermal storage economics, efficiency limits, vendors, and industrial heat use cases.

Is Neutrino Communication Possible? What the Fermilab Experiment and Physics Actually Say
Fermilab MINERvA demo, NuMI beam, DUNE, IceCube, Hyper-K, submarine ELF limits, muon storage ring projections: neutrino comms fully assessed.

Vacuum-Splitting Warp Geometry: A Zero-Integral Toy Model for Exotic Stress-Energy Compensation
A speculative vacuum-splitting warp drive model exploring zero-integral stress-energy, negative energy limits, and QEI constraints.
Astronomy
Gravitational Wave Communication: Can You Actually Use Spacetime Ripples to Send a Message?
A lab emitter radiates 10⁻²⁷ watts. LIGO detects black hole mergers at 10⁴⁹ watts. That 76-order gap is why gravitational wave communication is TRL 1.

Post-Industrial Villages: Human-Scale Production, Adaptive Reuse, and Local Economies After the Factory Age
Local production, adaptive reuse, and shared infrastructure are reshaping communities after industrial decline.

Perfluorocarbon Liquid Breathing: High-G Tolerance, Saturation Diving Beyond 700 msw, and the DARPA-to-FDA Path
PFC liquid ventilation, HPNS, G-LOC, Inolivent, Orixha, NEDU, and 711th HPW: what the science supports and what remains unvalidated in humans.
